Check the IPL for your saw to see if any special tools are needed.
There are metal piston stops available, when square with the piston top these work well, if not square they have been known to punch through the piston. I suggest a length of starter cord or nylon rope be used instead of the piston stop (retain 6" ± so you can remove it). Make sure the piston is near the top of the cylinder before feeding the cord or it can fall through the exhaust port and damage the piston as it rises.
It is probably a left handed thread (tighten it to loosen it). Let us know how it worked for you. GL

I had water in my hydraulic fluid in my Komatsu D39P dozer. I opened the drain plug, drained the resevoir and pumped as much of the contaiminated fluid as I could out through the filer port. I refilled the system through the resevoir and bled the cylinders through the line connections until clear hydraulic fluid was coming out.
The fluid is now clear, the reservoir is full but the machine will not push or engage the tracks properly. It acts like an air/vapor lock either in the transmission or torque converter. I was told this was a self bleeding system, but how do I get the air out? There are bleeders near one of the filters and I've tried that. I don't have a manual. Is there a sequence for bleeding this system?
