Hi,

I had a little mishap with one of my 2 meter pattern.....anyway that led me to disassemble the engine but to my surprise the crank just sort of fell out......I taught no problem I do have a spare set of bearing (OS one)...but to my surprise I can slide the new bearings (both) into the crank without any effort....now the engine have only have about 40 flights on these....they are usually good for about 100+ flights.

Out of my three 140 this the first time I notice that....also this is my newest engine, purchase spring 2002 new. The bearing look in pretty good shape...just the slip thing I'm not sure I like, since it could indicate the crank turning within the bearing, but at this time there is no mark on the crank that indicate that.

If the bearings are a smooth fit on the crankshaft, but there's still enough resistance that they won't fall off the crank by gravity, there should be no problems. We've seen a lot of engines with a very smooth fit. As long as there's no wobble of the inner race on the crank, there's no problem. A bearing doesn't have to be such a tight fit on the crank that you have to drive it on.
