Title: Advice needed for Changfa 1115 balance shaft bearings replacement
Post by: rcavictim on June 12, 2017, 08:45:10 PM
Anyone here replaced these?  My engine recently started to make somewhat more gear clatter noise and I suspect I might have failing bearings inside.  What I want to know if this can be fixed without taking the flywheel off or any flywheel side covers?  Where the engine is mounted in the steel box frame I have access to the timing cover where the throttle control is, the rear cover under the electric starter motor, and the top cover.  I plan to look inside the rear cover first since both balance shafts are right there and can feel the bearing play at that access point.

Thanx for any suggestions.

Rob

Sorry Rob, I haven't been that deep in one of these. Yet. But I suspect from looking, that the whole shebang will have to come apart.
Sorry.
Ron.

Thanx Ron,

I had a look at it after I posted and I think you are right.  The flywheel has to come off to access the two bearings on that side.  Also looks like maybe the oil pump is hanging out over the end of the lower balance shaft, behind the flywheel.  Guess I'll be without use of this genertor for some time then.  Not up to major work like this at the moment.
