Good evening, regards, friend, could you tell me how to put the os 70 surpass 4T engine in time, since it disassembled and nobody took into account the detail of how the time was. I would appreciate your help in solving this problem. Thank you

So you pull the shields on both bearings except for the front bearing, front facing shield?

Just stripped my fs-120 and it too has shields on the rear bearing so this must be from factory.

Hi Dave, have you tried installing the piston in the sleeve, but leaving the wrist pin hole exposed at bottom of sleeve and slide the sleeve in crankcase with rod on crank, then push wrist pin through the opening on case.its seems to go in with less hassle.

Another great guide! Thanks! Can I ask, how do you use the CLR? Soak the part or just apply and brush with a tooth rush and wash off?

Dave - thank you so much for the amazing videos! I am about to start restoring a 1.20 Surpass II engine with a pump that was given to me. Pump and carb are in excellent condition, but bearings are notchy. Do the OS 1.20 Surpass (I, II, and III) use the same crankshaft bearings and camshaft bearings?
