Stihl 020T workshop manual

[charlieh]

Hi could some one please let me have an electronic copy of the 020T workshop manual, I need to do some work to mine and cant quite work out what I need to do,

I have had the saw in the local dealers who said the piston has had it, and that the cylinder has as well, which is good as they didnt take it off, the piston has some scoring but the cylinder has a tiny tiny amount that i can just see below the exhaust port, Is it practical to just polish the slight cylinder scoring out or should i really invest in the cylinder as well?

The reason i am doing this is as the dealer told me to scrap the saw as he wanted £200 ($400) for the parts and then labour on top (about £25/hr), i can get a new stihl P+C for £140 and fit it myself, so do you think i need the new cylinder, or is just replacing the piston just going to be a tempory fix?

the saw will get maybe 5-10days a year use! not every day

Cheers for any advice

What is the compression on the saw? How did you see in the exhaust port without dismantling the saw? They are a pain to work on because you basically have to take the whole saw apart to get to the piston. I am sure that is what all the labor charge is. I would want to know why the piston scored before adding more $$ to the saw.

You could hone the cylinder and put a new piston in it. PM me your email address and I'll send you a manual. And you'll want to find out why it scored before sinking the money and time into it and then have it do it again.

I know about the exhaust port, as once i got it home I stripped it down, the dealership had writen the cylinder off, without taking it to peices. They have only been a stihl dealership for 3weeks! but have been husky for at least 5years. I havent dismantled that many saws but it wasnt that hard to strip down after the carb was off, (getting it back to gether could be more fun! )

I suspect that the saw had not been set up correctly and had been run lean for a prolonged period, which has lead to the scoring, everything else seems correct

I may be mistaked but I think you can go to Stihls web site and down load a copy of the manual for that saw.

I have the shop manual but unfortuanatly it is on micro fiche and I have no way to transcibe it into a form I can send via the internet.

yes you can download the owners manual for stihls site, and i also have the IPL, I was after the shop manual. the problem i am having is the removal of the snap rings that hold the piston on. I cant see an easy way of removing them? how does everyone else do this?


regards

I took a small ice pick type think and was able to pry it out. It's got a 2 inch shaft thats about 1/8 or 1/16 round and comes to a point at the end.

---- and get in the middle of an uncluttered room,those things can go into orbit once they get loose and are like looking for a needle in a hay stack.Best bet for reassembley is to trot on down to your friendly Stihl dealer and buy new circlips.Install them with the gap up or down,never side ways.As to up or down,nobody can seem to agree but all agree that side ways is not good.

 

[charlieh]

so i am ok to replace the clips that are in it with circlips? to make any future disassembly easier (not that i plan to have to do this again)

 

[chainsawjunky]

I think you misunderstood him or miscommunication or something. You can't use the circlips you're thinking of. You need the piston clips. And the gap in the clip should be facing up so that the gap machined into the piston is closed.

Ah ok! glad i checked on that one rather that sticking some normal circlips in Cheers for clearing that up!

Ha,just a Yankee generic term for "piston " clips,not internal snap rings.It's kind of like us saying parts and the Ausses saying bits,means the same thing.
