Model Forum / Radio Controlled / Air Models / November 2003Help on engine disassembly
Hi, I've been away for 3 years, so I'm a bit rusty... Can anyone tell me how to remove the crankshaft and the ball bearing on a topaz .46? I can't figure this out... I've tried to use my head, as well as brute force but alas... Is there a trick to it, or a special tool perhaps? And yes... I've removed all other components but this is my first engine with BB's and I don't think I've ever done it. :p Stefan Pettersen Stefan, Warm that engine up in the oven and then try it. 250 degrees or so. This will expand the crankcase and make it easier to remove the bearings. Don't forget to wear gloves when you take it out of the oven!! THen lay it on a wood block and tap the crank with another block. The crank should come right out. Eddie Fulmer Thanks, I'll give it a shot :P > Stefan, > Warm that engine up in the oven and then try it. 250 degrees or so. This > will expand the crankcase and make it easier to remove the bearings.

For you Norwegians, that should be about 120 degrees C, which is about 250 degrees F. We don't want you to melt the engine! :-) > Thanks, I'll give it a shot :P > > > Stefan, > > Warm that engine up in the oven and then try it. 250 degrees or so. Haha, thanks! I didn't fry it, thank god... I didn't think of the Farenheit scale, but I thought "Dang! That's hot!" So I wen't for a little above 100 degrees C. > Don't forget that we use the old-fashioned Farenheit temperature scale here in > the USA!
