Ok... finally got the "not mine" crap off my bench...
Time to get the 056MAG2 built up.. I've been slowly accumulating NOS parts.. and now have enough to pretty much rebuild the entire saw with new parts. The case sides were mismarked as "056 super"; the tank was missing gaskets and mislabeled... and all were coated in grime, dust, nicotine stains, and other crap... Dishwasher... (shhhh!) and they came out nice...
First..... insert NOS bearings into the new cases sides.
The NOS bearings and crank were locked up solid - nothing bad - just the old packing grease had "soaponified" - or.. dried out... Brake cleaner and they were like new (they are!)...
I removed the oil tank vent and all rubber parts as prep for heating in the convection oven.
The flywheel side will be easy - heat it to 300F for 20 minutes, and the bearing will drop in. The clutch side has a steel insert, and presents more of a problem as steel expands much less then mag, so the bearing is likely to be difficult to insert unless everything is perfect.... It needs to locate against the inner circlip. The easiest way is to insert it from the inside, but unless you have a backstop, there is no way to press the bearing in square. If you're not exactly square, it will jamb...
Find a piece of pipe 2 inches OD and square up the ends, or.... if you have a lathe, make one... The piece on the right is a cheap Stihl bearing mandrel. One end does the clutch side; the other end - the flywheel; fits many saws/bearings. MUCH easier than sockets and other mickey-mouse approaches! Time is of the essence.. and fumbling around while the bearing heats up isn't good....
In the arbor press... backstop beneath...
Both bearings in place... Love those new case sides!
Interestingly.. the case has a serial number.. which means it was pulled from production rather then as a "spare"... I might register it with Stihl... and get my warranty... lolol
To be continued...
