I'll share here too.

OEM Stihl piston tools I use from stihl that make removing pins easier. Cheaper to buy really since like 5 apiece then time to make on lathe.

Yes I used to redneck use dowels, sockets etc etc etc too. But one day I said f it and bought a set to make life easier. Time is money.

Poulan etc pin puller I got from Chris at sawsalvage for $23. If you aint got the oem tool or redneck your own. This maybe makes it so easy.

Pulling parts from a parts saw for a guy. 3700 thin ring piston and cylinder.

Been using for many years now too. Stihl one for close to 10 years.

Once you got right tool you wont go back. Just a no brainer when tools so cheap for job. Stihl 5 bucks.

The tapered punch sometimes would get stuck and mf to get out. Plus bigger pins the redneck stuff didnt even fit would go right through. Why had to use dowels etc.

Never had a problem removing or inserting a piston pin. Should have ~0.001" clearance, not a press fit.

Circlip tools can be handy.

My scrap oak piston support.

A little heat on the piston from a heat gun (preferred) or torch will also work wonders. Main thing is to clean the deposits off of the exit side of the pin bore. Did this recently on an Echo PB-500T blower.
