My 2 year and 1 month old chainsaw died on me and I was told that it needed a new piston. For the $20-$25 for the piston kit, I'll give this a shot. Thanks for the great instructions!

@rogerhughessr5588 4 года назад

Removed and Replaced old/new piston per your excellent instructions. Thank you very much for the video......three pulls and it started.....I'm amazed.....thanks again saved me a bunch of money!

@David-uh9cc Год назад

This video plus the other video on poulan chainsaw Piston replacement (more detailed) really provides a thorough tutorial...with these two vids, ya can't get it wrong... I threw in a carb rebuild kit since I had the thing tore down anyway..

@mrjwsouth 7 лет назад

This is an excellent video to show how the piston is replaced when you have a need to , like low compression

@farookbanian3304 5 лет назад

This is progessionally done. The instruction is so clear. Thanks.

@williamphillips7210 6 лет назад

First I want to say great video. Second I just wanted to know if there is a break in procedure or new piston.

@winstonclarke9221 6 лет назад

Mark, That was very neatly done, Great video.

@rogerembry4777 6 месяцев назад

Best video Iv seen yet on doing this

@Bigeye291 3 года назад

Hello mark great video, but what about the timing of the spark and piston

@woodfinchcrafts7267 5 лет назад

Excellent video. My saw is now running (including new cylinder - which was scored). Two additional comments - there is no need to remove the oil pump screw, and it is a lot easier to screw on the rubber carb fitting before putting the cylinder back into the frame. That was never removed in the video, which makes it easy to miss

@on_another_level5661 6 лет назад

That sound effect in the beginning of the video led me on a 30 min search of my backyard to find who knocked on my glass backdoor. This video auto-played unknowingly....and caused QUITE a scare. Haha...smh

@yogakausik1 7 лет назад

Would you please share a video introducing all the different parts in two stroke engine with their mechanism, how they work.

@philliphall5198 11 месяцев назад

Thanks for sharing information and advice 😊

@pondhollow 4 года назад

Great video! Exactly what I was looking for. Appreciate this channel very much.

@philliphall5198 Год назад

Before you start run a bore camera in spark plug hole and inspect cly for damage, keep you from having to wait a week for kit. Also it’s fresh on your mind and less likely to remember more

Great Video, only problem was i have a Poulan 50CC. Pretty much same concept. Was able to completed the head and piston swap out.

@FIXTechGuides 6 лет назад

Glad to hear, Michael!

@dereksmith4178 4 года назад

I just I installed a cylinder kit and piston following your instructions but my compression is 77psi the exact same as the old piston? I am confused where else my compression is escaping?

@winstonclarke9221 6 лет назад

Got your reply thanks, Mark, one more thing do you always have to remove your clutch, just to change piston rings on your 2stroke weed wacker.

@paolachang8787 5 лет назад

Excelente video Mark Muy bien explicado y con una secuencia acorde del video Felicitaciones !!!

@benbrewer5853 4 года назад

You probably should have mentioned that when taking that clutch off the right-handed thread to take off in a left-handed to tighten it up

@tier3rd375 3 года назад

It's clearly written on the clutch the direction it needs to spin to remove it.

@hulenweston 3 года назад

I would say something these poulan's are on the easier side of saws to work on

Very true

What liquid gasket is used?

@johnkosheluk1041 4 года назад

It is nice when you work on a brand now saw I work on still chain saws for a living

@tedbrewer7847 2 года назад

How did you insert the piston into the cylinder without a ring compressor? Also is the bearings attached to the connecting rod still? I took my saw to a repair shop and because of the score it was condemned. It took you 20 minutes to change them. Me probably 2 hours, but repairable. Parts 20-30$, cost to replace, $150. Thanks a heap

@FIXTechGuides 2 года назад

The bottom of the cylinder is beveled which compresses the piston ring as it is inserted into the cylinder. Yes, the needle bearing is still attached to the connecting rod. I'm glad we were able to help you save your saw and save a few bucks! -Mark

Just did this and the cylinder on the poulan pro 42 cc. The video was a life saver as me working on small engines is normally a death sentence for the engine. Aside from a few extra steps for the cylinder- all was the same except the throttle cable is non-trivial on the pro model...and I ended up unseating it at the trigger when trying to re-attach the cable to the carb. Might be better to take the trigger apart when taking it apart since it's pretty simple to reattach it at the trigger vs at the carb. Also on mine- I'm suspicious of the oiler actually getting oil to the chain. I got the spring on in the right direction (watched closely on that part) oil is coming out from somewhere in there but when I run it wide open, the chain should be flicking oil, but it's not.

@woodfinchcrafts7267 5 лет назад

I took my trigger apart - pretty simple to put back together, even for me

@dhswede Год назад

The cylinder head inserts fell out when you disassembled it. You put them back in but you didn't show that in the video.. There's a left and right which I guess are different.

@joelshoe96 5 лет назад

Donny I have had a couple of Poulan chain saws. Both leaked/leak bar oil out of the case to the point that they will empty if stored in upright position. But that is not my concern for today, A year ago, while working by a stream I got it wet, used it throughout the day but never ran great after that. It has since gotten harder and harder to pull start it. I took the exhaust off but still cannot pull it over fast enough to start. Takes 2 hands to even pull it all the way out. Pulled the spark plug and turns over with 2 fingers. Coated the piston from the exhaust side and from the spark plug side with WD 40 and later a heavier oil, but still cannot pull it over at all. Read some of your posts about gas oil mix but I have gone thru many tanks of gas when I could get it started. Any thoughts would be appreciated.

What liquid gasket do you use to seal the crankcase? Thanks!

@tr4415 4 года назад

I just did this job on my 2017 Poulan pr5020... 50cc with a 20 inch bar ... I used J-B Weld black silicone RTV gasket in a tube from AutoZone ... seems to be working

@tedbrewer7847 2 года назад

Black RTV. It’s used to seal intakes on vehicles and is resistant to petroleum and heat

@jzventurez4561 4 года назад

@winstonclarke9221 6 лет назад

Good video Mark, can you tell me what causes a lot of blue smoke and gas to come out your exhaust, Thanks.

@FIXTechGuides 6 лет назад

Hi Winston, there are a couple of causes for blue smoke emitting from your exhaust. One could be to much oil in your gas/oil mixture if it is a 2 stroke engine. The other cause would be because of worn piston rings, letting oil into the combustion chamber.

@tr4415 4 года назад

Just had to do this job on my 2017 Poulan pr5020 ... piston ring got stuck in the Piston Groove due to carbon buildup... happened during storage... about two months ... when it went into storage it was purring like a kitten ... 2 months later I needed it to cut a limb ... wouldn't start ... only making 25 lb of compression ... piston ring somehow got stuck in its Groove and was no longer riding on the cylinder walls to make compression ... took it apart ... put a new ring in it... cleaned out the Piston slot for the ring ... got in touch with Husqvarna by email ..Expert Tech Department ... torque specifications on my saw for the four bolts that hold the engine crankcase and plastic saw frame together... 7 1/2 to 8 and 1/2 foot pounds.... then heat cycle the engine and recheck... and that's just what I did and she's running again ..😉

@dennisneuhaus2607 5 лет назад

There are things you left out about gaskets, seals and the such. If you are going to tear down a saw this far, especially a Poulan, you might as well rebuild it all. There are many prior steps to be considered. Needed more info about cylinder scaring.

@monsterkhaos9292 5 лет назад

You know be cool if you could put a whole different motor in there a different one than a Poulan Pro one. Wander if that's possible

@jamesharbaugh9078 6 лет назад

If the cylinder wall has been damaged, can you hone it with good results?

@FIXTechGuides 6 лет назад

Hi James, from what i have heard, if the cylinder is not terribly damaged, I have heard you can hone it .010 but after that you will need oversized rings.

@paolachang8787 5 лет назад

Es correcto Si la corrección excede los .10 deberás utilizar ring's sobremedida y si es mayor también deberás cambiar a pistón super medida

The instruction is so clear but mounting error - minute 9:39 .

@dennislanier216 5 лет назад

Very detailed

@NathanVdV 6 лет назад

all nicely explained but! why do you dry fit everything? these machines need oil to work, when sliding in any piston rod, or piston in the cilinder lubricate it!!! with 2stroke oil. you are scratching everything up even before use. and yes it may smoke a tad more on the initial run but at least you know its all lubricated more then enough to prevent scratching.

@FIXTechGuides 6 лет назад

Thanks, Nathan. We will definitely keep that advice in mind going forward, and make sure to show it in newer videos!

@woodfinchcrafts7267 5 лет назад

? I thought the video said exactly that?

@JohnDoeEagle1 5 лет назад

This looks like a interesting weekend project for those who are mechanically inclined. The payoff is prohibitive otherwise. This is way too much work and money invested on a junk, cheap box store chainsaw that was designed with a 50 hour service life. Better to cut your losses and go get a quality machine like a STIHL that actually is worth rebuilding. At least you will have something when you are done. You can polish a turd all day, in the end it's still just a shiny turd! John

@seanbush5313 5 лет назад

for the low price of the rebuild kit, I would say its more then worth it

@TheSubpremeState 3 года назад

Imagine doing all this and finding out your cylinder is scored also

@philliphall5198 11 месяцев назад

AllWAYS remove muffler and look at piston and see what shape it is in or look down plug hole with bore scope

@TheSubpremeState 11 месяцев назад

@@philliphall5198while you're there......If I remember correctly I didn't bother going ahead with this tedious looking job as a local shop told me the cylinder and cylinder shaft should be matched perfectly. I got a cheap piston( from Germany though ) and was told it should be mated? to fit the cylinder
