Trx400ex Bottom End Part 1 How to Split Cases 

Thanks bro. All that is in the viewers hands to share the videos

Thanks for the sub bro I appreciate it

This quad is all this week bro

Before you buy any parts lmk. I have cranks, cams, and some other stuff too

Thanks bro I try

Oem when possible

Thanks bro. Trying to get the channel up there. I'd like to start building quads to give away.

Part 2 is putting this engine back together

@@garagemcmatt would be sick

@@garagemcmatt yep ima check it because I have lots of part coming in

@@HaydenForgues have fun bro 400ex's are easy and fun to work on

The pivot bolt that goes through the swing arm? They get seized all the time. Your gunna need to soak it a few times with pb blaster for a few days and either use an air hammer, a slide hammer, or cut it out but try all the other options before cutting it. It is not fun but keep at it and u will get it out

You could leave it on if that's what you wanted to do

If it's a non reverse engine it's a 99-04. The only difference I know of in those years is one of the bearings is different but any good bottom end bearing kit will come with both style bearings. You might be able to find out the exact year by those numbers but I've never tried

It would be the basic idea of it but not something you could follow for a 250x tare down and rebuild. Same principle tho. I have a 87 250x parts bike if you need something

@@garagemcmatt thanks do you have an email?

Lol. What are u to good for your home !?

@@garagemcmatt every bolt has a home, who I'm I to re home one, lol

@@johnbruzzi4381 lol

The bearing on the stator side is a sweat fit. The bearing on the clutch side is slightly less tight but shouldn't just spin freely on the crank

Oh ok

Thanks

You mean the spacer that goes into the cases or the 2 that go in the swing arm?

@@garagemcmatt Between the swing arm and case, I made a video of it. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-625W08C2UbM.html Also this thing is a 2001 (10th digit of VIN) with Reverse so I guess the engine is newer. Is the wiring the same between the years? Because it's wired to jump the solenoid and drive, none of the controls switches function and stuff is disconnected. I've had this less than 24 hours and already ordered a ton of parts and been looking thru your videos. Thanks in advance for any info.

@maglight2006 the reverse came out in 05 and the wire harness and cdi are different. When I get home I'll check out your vid and see if I can help

@@garagemcmatt I see it now, it's the inner race of the swing arm bearing, the one on the right side extends all the way to the case. Mines gone, they left it out. This ones going to be a fun project.

@maglight2006 yes those inner spacers come with a pivot bearing kit and there are 2 of them and the one on the right side is longer. If your bearings are good still and u need that spacer only lmk I always keep take off parts like that

Yes you do

You can see why in part 2 of this engine

The new crank and bearings? 3 to 400 for the parts being oem

It was from BP in the beginning then someone that had no clue touched the intake side. Looks like they let a beaver loose on it

That's what I thought

Yeah bro it's bullsh*t for sure.

Broken or it has a 99-04 engine on it?

@@garagemcmatt definitely not broken. But I've followed the protocol for reverse and it doesn't shift into a gear. I myself never changed the motor so I don't think so to be honest.

@@kodeland7729 would be tough to take a guess at what it could be just hearing about it. I'd start with the reverse cable and how it goes together inside the engine at the clutch cover

@@garagemcmatt it very well could have been removed by previous owner. I'm the second so I don't really have the right to say I know for sure

85mm is stock, 86mm is a 416, 89mm is a 440, and 89mm with a stroker crank is a 465 in most cases

@@garagemcmatt oh okay, I thought 86 was the 406. My bad.

@@Ninoo187 it's all good bro. If you break it down the math don't make sense but that's what they call the sizes

@@garagemcmatt well I bought a kit that was advertised as a 416, and it came with an 87mm piston that's why I'm asking. Thanks to your videos I finally got to finish my build yesterday.

@@Ninoo187 that's cool bro I'm glad it helped. That's what it's all about
