Hi
The engine builder is finding it very difficult to remove the piston ring pegs on my piston (part numbers 5268 and 5269) Have any of you done this or are they available to buy. I seem to remember reading somewhere that there might be a fellow in Switzerland selling some parts for these Simars. I attach pics.

Hi Charlie
It’s the RD310 I have. Could I get the drawing for that spring. I’ll do a Solidworks drawing of it if it’s not already in Solidworks and make available free.

Hi again
Just wondering can the springs for the tines on this machine be purchased anywhere. If not I’ll draw them in Solidworks and see can I get them made.
The piston and cylinder is with engine remanufacturer at the moment.

Found this maybe you’ve seen it already. There’s a few photos there too.
Practical Machinist.believe this to be an “Orolo” track unit, or a copy of one. “Roadless – The Story of Roadless Traction from Tracks to Tractors” by Stuart…[Read more]

Every day’s a school day. What I thought was a split pin is the bottom piston ring divider. I attach a photo.

No I think you’re getting it wrong. Read it in this photo….not the one you added

Hi Wristpin
Attached is photo of the can of Owatrol oil.
It’s definitely better than WD40 anyway. -

Thanks for the books Charlie.
I attach pictures of the piston and cylinder which finally came apart just now. The cylinder looks OK but I won’t know for certain till later. The piston has a little damage. Rings were broken. And a break between the rings as well.
Anyway what do ye think…..is it repairable?

Thanks Charlie. I could use a copy of the parts book please. Might not have to take the crank apart…..hopefully…..Will try get the piston out the bottom today. A lot of this is learning for me.
Thanks again.John

It’s a split pin for sure. Looks like there’s a flange on the bottom of the cylinder but I wouldn’t be sure. It stops the piston coming out the bottom. The pin doesn’t come out the cylinder either.

1. I attach a picture and am wondering what the split pin is for?2. How to remove the Big End bearing. Picture attached as well.

I knew that before I started. I might refill those holes and see can I balance it some way.
I doubt it would have come off any other way. The starting ring was beginning to break apart when I tried that.John

Got the flywheel off after a lot of drilling and grinding and heating. It shot off like a rocket when I hit it with a hammer. Flew about 2 feet. Luckily I wasn’t standing in front of it.

I tried most of that. The starting ring started to break so I stopped before it disintegrated. Thinking now if I drilled two holes in the flywheel big enough for the pullers to go through to the back of the flywheel might do the job. I’m using wd40.

Hello again
Does anyone have any suggestions for removal of the flywheel from the 56. I have the nut removed.
