.91 OS surpass problem
I've got a .91 surpass os engine that I got from a guy that has been setting around for 8 years. I'm trying to get it apart without messing it up. I got it down to the cam piston and sleeve. I just trying to put new bearings in it. Thanks :eek:

RE: .91 OS surpass problem
You will have to raise the sleeve up and out of the engine
With the crankshaft pin at about 11:00, slide the connecting rod off the crank pin. The connecting rod is most likely gummed up and will not let the rod slide all the way back? After the connecting rod and piston are removed, the crankshaft can be removed out the rear. You will have to heat the crankcase in the oven for 20 min to get the bearings out. |

Heat guns work too if your Mrs. or Mom doesn't want the sweet smell of engine rebuild in her oven... ;)

One more question. I got it apart, were to buy new bearings at and will anything else need to be replaced? Nothing is rusted up, just really gummy. :)
