well I was disappointed to say the least. the pin didn't move and the cylinder just shows marks from the bearing pins on the intake port.. Mark is being gracious and helping me out.

I pressed the oem bearings in and they where firmly in, and I used the oem pin like you all told me to. everything was a tight press fit. I used redkote and followed the instructions. I guess I will dig out the seams and JB weld and redo the redkote. I lucked out and didn't eat the cylinder...

Well the PM800 rebuild ran for about 3 mins and then locked up. (It was rich and I was cutting some old pine, not pushing it at all.) pulled it apart finally the piston had granaded red barn piston oem bearings and pin. cylinder is savable thank god. (two dings from bearings in the bottom of...

They are the knock offs. I will see if they hold up better than your experience. If it works then I will spring for a real one.

hea you got me there, I have bad shoulders and it is an experiment to see if it helps. the original is safely in a box.

one of my current projects bringing a 450 back to life. Pulled from the local transfer station with a 28" bar (that needs work too) new rings and a set of better used main bearings and the normal parts.

Making progress on the PM800- just need a few screws for the starter cover (on order) and see if I can find or make a handle insert. (3d print possibly ) thanks for the help.

I'll dig in the tank a little more and see what else is in there. it is looking like I will need a new one with the missing bits. Just looked at the cap and I can see where something should screw into it but nothing else in the tank.

PM800 question, I found a black duckbill in my fuel tank (it is disassembled for a full rebuild) Where does it go? on the bottom of the fuel cap? How is it held in? the retaining assy is missing on this saw and I am guessing that is what retains the Duckbill in place?. looked at the IPB and no...

defiantly an 800 and Like I said it is all machined put the final drill hole. (I have bad shoulders )

another question on my PM800 it has the boss for the compression release and the threads but no opening, it is into the side of the cylinder wall I assume that drilling it is a no-go due to the plating?

any recommendations to match mc yellow paint?

I just pulled it and the rear plate was loose, The gasket pliable , I cleaned and inspected and used a thin thin wipe of sealant on both sides (gas safe type) and have a nice bow in the spring steel plate. I think it will seal up ok. Just another reason to pressure test. and I appreciate all...

I watched the vid. I had a suburban load of saws years ago, quite a few went to folks here, and I rebuilt many and either sold and passed them one to new owners or kept them. Do you plan on selling parts?

thanks for the help, I haven't worked on this one before, it was given to me by a dear friend who has passed. I finally dug it out and am working on it. (been sitting for 10 years.) the saw was low hours when it seized (his son was using it) so it is in good shape otherwise. I have most of the...

I am working on a Promac 800 that had a bad piston, (was able to clean up the cylinder ok) One thing I noticed is that there was quite a bit of chain oil in the crankcase when I took it apart. I know the oiler is connected to the hole in the bottom of the clamshell, is this an issue I should...

WTT Husqvarna 2100cd (with bar I will have to measure it tonight) for a 20" bar chainsaw, Husqvarna preferred (60cc and up preferably with a compression release. ) ran great But I cannot start it anymore due to a torn rotator cuff. I can provide compression results and a pic with the muffler...

Someone in the thread suggested several times to make one from a piece of car brake line just smack one side with a hammer and then stuff it on. you can bend the other end for a handle.

Mine came in yesterday and had all the goodies and has good compression. I will get to it this weekend for a test. Happy!:hmm3grin2orange:

Well if I have to do it I break it down wirebrush wet the joint with a little water and then apply the cement and reassemble. Done properly you will get many years of service out of it.
