4k Shimano Tranx 400/Tranx 300 full maintenance and service tutorial. Disassembly and reassembly 

Do not use metal tools around the rubber seals treated with Core Protect. Always wear nitrile gloves and use of plastic tweezers when dealing with these treated seals. The frame to spool seal and clutch button seals have this coating. Use of metal tools or bare fingers will remove the coating. The effectiveness of the seal is degraded once the coating has been removed. Also be careful using oil and certain greases other than what Shimano recommends to preserve the coatings. Some cleaners can also remove the coating.

You are the SHIZNIT!!! I watched the video twice and disassembled my reel! Step by step, part by part, obviously you already know how good this video is! This video is awesome! Thank you, for all your hard work. It lets us “ plebes” attempt things like this!

Skip to 23:10 for the start of the reassembly. Also feel free to watch at 1.5 or 2x speed if you want an overview!

I got a 300 as a swimbait reel last year and just cleaned it for the first time. Very impressed after a year with it and now seeing all the internals. I replaced the worm gear bushing with a bearing and just lightly lubed everything since it won't be seeing any salt. Butter smooth.

This reel looks very thought out. I'm kind of impressed by how it was built.

i would be so afraid to do this service on this brand new reel... But damn great info brotha. I need to buy one of these 400

I really enjoy your videos. The video quality and narration are top notch. Can you please do a servicing video of a Daiwa Saltiga 15H or a close relative when time allows and a comparison video of it to the new Shimano Ocea Jigger would be awesome too

I got into my TranX 300 and serviced it with the Quantum hot sauce grease and oil that seems to be good stuff when I used it on my ABU 6500s CL Big game ,Blue yonder and Inshore model the grease didn't migrate away from the teeth of the gears like the Penn green grease. and the reels operate smoother.

Most useful reel service tutorial on RU-vid! Many thanks. Could you also please show the removal of the spool bearing pin?

Make sure you grease up the BNT5506 clutch cam retainer very well (the part held with two screws and two long post sticking out at 12:50 with the number 1712). That crappy part is made out of a cast metal and easily corrodes. If its badly corroded, you lose the ability to use the clutch to go into freespool. Its the worse component inside the reel.

When I cast over my left shoulder the reel spins and the saltwater goes in on the gear side ( facing down ) at the end of the cast through the spool gap. When I take my reel apart the inside of the cover on the handle side is full of salt and the clutch bar and dog bone and spool tension bearing.

shoutout from Malaysia. great video . am thinking bout getting my hand on the tranx300 for snakehead fishing in heavy cover

Awesome! I was considering this reel for swimbaits and was leaning towards some cheaper options but as someone who like to clean my own reels this is really enticing to see.And yea I am jealous of that e-clip tool lol. Those things are annoying.

Extremely helpful video, I can’t thank you enough!!🙌🏽🎣💪🏽

Best fishing channel. Thank you!!!!

Hey, many thanks for this. Just wanted to check what you do to clean the bearings, especially on a reel thats been dunked in SW a few times.

Excellent Help! Freshwater Questions: There are two thoughts on greasing Worm Gears and Fiber Disks. I choose to keep both dry in all my other reels. Grease holds dirt on the worm and my drags are fine. My biggest item that jumps out is that you do not Oil bearings in the Video! I use Clenzoil and seem to have great performance on my other reels

Just wondering about the spool bearings. How do you clean them? How often What is your preferred oil? Thanks

Thank you for everything you do.

Awesome tutorial! Thank you!

I need to figure out how to get the roller bearing clutch out

Love your content. I will be receiving a SHIMANO Tranx 300AHG Baitcasting Reel in the next few days for Father's Day. I prefer using the double paddle handle. Should I just purchase the Shimano OEM handle or do you suggest another. Thanks.

Thanks so much pal. Great video !

Try Permatex 81950 Ultra Slick Engine Assembly Lube...liquid but sticky..

awesome tutorial! could you make a video on how to upgrade the bearings?

Just discovered your Channel. Great videos, I really appreciate your focus on design and build quality! Do you see a ergonomic advantage of the 300 over the 400 (I have XL to XXL glove size), maybe a higher tendency of the rod rolling from side to side while cranking? Wich one would cast 1-2oz lures further assuming a full spool and the identical line type on both?

Hi there, would adding a drop of shimano bantam oil to the side cap of the tension knob, worm shaft, handle knobs and both ends of the spool after every 4-5 uses be ok? Or would it damage some of the sealed parts ? Or should I just continue to use it and get it serviced once a year?Thank you! Love the channel

So I bought one of these (401) and brand new out of the box the reel will not freespool when the thumbar is depressed. I have not taken the reel apart. Simple fix? Love your channel.

Awesome this will come in very handy very soon. Can you please do one for the talica and Trinidad?

Great and detailed video

I just bought a brand new tranx 401 hg and after using it once in brackishwater and not using it for a few days I found that it was locked and I had to break it in again, but then it performed perfectly fine, what should I do?

Full maintenance on other Shimano Reels please! Talica Trnidads Tranx 500

Bravissimo!

Well done! Thanks!

I used to work in a fishing shop in college working on reels. What grease are you using? Im considering buying one of these, and it appears that it follows old shimano curado simplicity and architecture with some hydrophobic goodies.

Quick question for ya: grease on the idler gear of the levelwind? Thanks, and the video was great.

Could you do a disassemble /reassemble of the Tranx 500?

Did you ever notice any play in the reel while messing with It? Like the anti reverse doesn't engage instantly. Straight out of the box i can move the handle 1/16-1/8 inch backwards before it engages. Normal?

I know that you did this video awhile ago but I was wondering, your opinion? Is a tranx300 is too big of a reel for my teramar 7'6" medium heavy ? Your opinion is valuable to me.

Do you know the size of knob washers? In my model from 2018 (301a) there were no washers, I checked 10 times. After knob plastic bushings exchange to metal bearings (4mmx7mmx2,5mm - adopted from lexa 300 knobs) looseness appeared around 0,5-1 mm. Not big deal but i would like to reduced it either by using washers or exchanging bearings to a bit bigers (4X7X3).

What's the best grease for reel? Or which grease you found works the best?

Thanks for sharing!!!

I have issues with the power handle on this reel periodically engaging the clutch mid-cast. What will this damage over time, if anything? The pinion gear?

BIG FAN AND LOVE YOUR VIDEOS!!! but as easy as an abu garica? lol...i need alot to learn

Hi. Any idea why I have to re tighten my drag every 10 minutes. It just decreases every time I'm using it. Even quicker when I am hooked on a fish.

I have a Tranx 300, 500HG, and a 500PG. I fish exclusively offshore, and inshore. My spool side plates have become hard to remove. Any tips?

Hi, I’m just wondering, I want to change the bushings on the handle knobs to bearings. What size are they or where can I find them. I’ve checked everywhere 😅

Can you do a video on right hand reel left hand casting reel maintenance issues. I have to service my reels twice as often because of this and was told extra grease helps.

Can you please tell me is it okay to put this reel on Westin w3 40-130 gram rod (1.5oz-4.5oz) ? What are the down size lures that Tranx 301 can cast? Like Super Shad Rap weighing 45 grams,will it throw it normally or its to big reel? And its okay to spool it with 40/50 pound braid? Wanna use it for pike lures in that range the rod is...Thx...

Such a helpful video. After changing out reel handles on my Tranx 300A I needed help and this was perfect. Hoping you could help with a concern I have. I’ve noticed upon reassembly of the star drag I only have one star drag spacer (part 2172) but the schematics clearly shows that there should be two. And I also noticed in this video there was only 1 on the reel you are servicing. Is that common? I have 2 Tranx 300 reels and the range of motion on the drag is drastically different. I think because one has 2 spaces and the other has only one. Idk...please advise!

@Tackle Advisors are you getting a Tranx 200? Would LOVE a comparison between it and the Curado K. Very interested in that one! I'd think many others too?

Hi the worm shaft is made of plastic?

Is it possible to upgrade the drag pressure? Like different drag washers or added springs etc?

I have lost the washer on top of the levelwind pull thing, now the levelwhind will get stuck and the worm gear metall will get really beat up and have scratches all over it. But for now the levelwhind is okay and the reel is working, but how till this affect my reel?

I noticed that you said you use warm water and soap to clean part... do you ever use degreaser/ cleaner like “Simple Green”?

Whould you choose tranx 400 or tranx 500 for casting big 200g+ rubberbaits?

Hello, what is a good option for a readily available reel grease to use in higher end Shimano reels? Thanks!

I have a tranx 300 and every once ina while the handle locks up. As soo as i take off the cover the pahl clutch springs back seems it gets stuck under the gear. Is there something not tightened down, and there is play?? Thanks

Hi, I have tranx 300 with power knob. Sometimes when I start reeling it feels the reel locks in not so smooth what do you think the problem. Thank you!!

I came to this video to see the level wind being taken out of the reel... however that did not happen so I'm looking for someone in the comments w experience for some help. I have my tranx 300 and the line guide is cracked... 100lb braid max drag grouper was a bad idea. Anyways I ordered a new line guide and its on it way and so Ive been trying to do some research on how to take that part of the reel apart in order to access the line guide and replace it. If anyone knows how to do that and can explain it to me or has any tips it would be greatly appreciated.

Are gear sets interchangeable for the 401? I want to put the lower gear ratio gears and drag washers in a 401hg.

This was realy helpful, thanks alot!

The star drag range is relatively small compare with Shimano fresh water reels. This reel doesn't have much midrange drags. If I install a couple of drag spring washers from other Shimano fresh water reels, will it affect the Tranx performance? BTW the worm gear on my reel doesn't have the black coating. They are exactly the same reels.

I just got the Tranx 300 and it has a bit of reverse backplay. Is that a defect? My curado k and bantam mgl have no backplay so it doesn't seem right.

I have a Tranx 300, 500PG, 500HG. The side plates to take out the spool have become difficult to turn to open. Any tips?

Having a heck of time pulling the drag stack off the stem like you did in the video. Any trick to it ?

Hi man, i really like your videos. I'm sorry if someone has yet asked, but i've two questions: which is the "lower weight" you can succesfully cast with 300 and 400 respectively? And, do you suggest me the 300 or the 400 size for both Sw and fw application? I'm gonna use it for Little tuna, amberjack and dorado that reaches max 30 lb here in Mediterranean sea and, sometimes, for pike and wels (wels reach about two metres length and 60-70 kilos) fishing in fw with lures that reach 2 Oz max, both for fw and sw. I asked a shimano pro staff for help: he told me 300 reel could fit best for these situation beacuse i can reach a better casting distance with the lures ill be using. I'm not fully convinced beacuse i think i will regret picking the little size beacuse of the less spool capacity (ill be using 30-40 lb for Sw, but at least 50-60lb power pro for wels). Can you help me to choose? 😊 Thanks a lot for replies and sorry for so many questions (and for my terrible english) 😁

How can you get the side plate off if one of the screws is worn-out

Finally got my own Tranx 401! Do you get better casting length with only spool- tension brake or only centrifugal brake?

Hey, just picked up the tranx 200.. what's your thoughts on removing those bushings for bearing? Pinion support bushing and the shaft bushing and theres one on the line level as well..and yes I know about the 4 in the handles.. just wondering what your thought where and why.

Do you know why the reel have resistance when winding as soon as I tighten the handle nut with just my fingers?

I need your help: my Tranxs drag is either tight or very tight. I cant seem to turn the drag star too far (I get like 1 full turn and it stops) so I never have super low drag settings - either tight or very tight. Any Idea where the issue is?

I have the tranx200 and took it apart for cleaning but my drag star won't click back in :(

Good day, please tell me what material is made of an endless screw on this coil? Plastic or metal?

I always replace my worm gear bushing with a sealed bearing. Idk why Shimano don't use bearings to begin with.

How do you like that grease that your using ? How does it compare to the usual stuff ? I checked it out its pretty pricey , Thank you .

do the same video for calcutta D reel

Can i use Cal's grease on all parts? It's the only one i have at the moment...

Can you do a disassembly and assembly on the scorpion dc, i fucked up the threading on the shaft not knowing that for jdm reels, left is to tighten and right is to loosen

I have an issue with my newer Tranx 300 HG where the reel loses its drag in colder weather. It can be mid to high 30s, so not even freezing, and the drag will be almost completely gone. Put it in the car to warm up for an hour and it functions properly. I've read about this on a few forums with no clear answer to the fix. Has anyone experienced this or know the fix?

Good info on the Tranx! How's the krytox 225 you're using? Any link where to order a 0.5 oz. syringe from? Can't seem to find any distributor in Europe... Thanks!

Hey guys, for some reason my spool isn't spinning when I release the "spool release" it's acting as if the drag is on. Any ideas?Thanks in advance

Im having an issue with my 400A 5.8 i fish it strictly in the fresh. Just the other day I tried taking off my sideplate to adjust the brakes. Only come to find my sideplate will not budge at all, like it's glued tight........ any reason why??

how is the tranx 300for casting distance surf casting

Its helpful but doesnt answer why my line doesnt reel in even when the drag is tight. And it makes a clicking noise as i reel in the line.

Hey man, I find myself asking for a help a lot here, but I have another issue. One of my shimano baitcasters is really smooth until you put any tension on the line, then I can feel a bit of resistance and lots of little vibrations, even when I’m just putting tension on the line to reel in slack line, do you have any idea what the problem could be? I took it apart and regreased it and it still hasn’t changed. I am out of ideas.

Is it possible to put the tranx gears on a curado 300e ?

I got a brand new tranx and the thumb bar is hard to engage and when reeling to disengage it. Is this normal is there something I need to do? It just seems strange being a brand new reel it take quite a bit of pressure to be able to cast. Any help would be great

not using any oil?

What grease are you using for your saltwater reels?

Hi...TA,The metal oval shape on the line guide(BNT5611) seem to be loose and easily drop off and lost, i found out on this when i was spooling a new line in..is this normal or just mine? Thanks.
