Thanks Tom. I was mainly showing over all condition because I did see the gouge in the outer wall where the oil seal goes. I swear that was not me! I was also inquiring about the large furrow in the middle of the race. I’m pretty tired from working all night and didn’t even click to that being an oil passage for cushion. I think it’s time to call it quits for the day and get some shuteye. I’ll address the gouge in the outer wall and get it lightly sanded before I put things back together….another day.Tom wrote: Sat Oct 08, 2022 9:55 am Not entirely sure what you are focused on in those pics, but it looks like the area where the seal goes got scraped/gouged a bit, so I would dress that so that no metal is sitting proud. As for the bearing inside that the b/s spins in, that wouldn't be the source of a leak. That bearing will have a cushion of oil when the engine is running, much like a crank journal or the like, and that oil is kept inside via the seal. If you see defects that bearing (hard to say from those pictures...), then I'd just replace it. It's a very low-load bearing that last a very long time, but it's also cheap and easy enough to replace.....

If memory serves, those are all M8 (13mm wrench) bolts that should be torqued to 15 ft lbs. Do those in stages and make sure the balance shaft doesn't tighten up too much as you go. If you just crank them down without paying attention to the balance shaft, it can end up binding a little or a lot.... In general, M6 bolts get torqued to 6 to 7 ft lbs., M8 bolts are 14 to 15 ft lbs., and M10 are 33-34 ft bs. Exceptions do apply -- especially for hardened bolts -- but for regular old 8.8 bolts, those specs almost always apply and are spec'd by the factory for any bolt not having its own listed spec.StaceyQ944 wrote: Thu Oct 13, 2022 3:28 pm Does anyone have the torque specs for the 3 bolts on the front of the top balance shaft support and the 3 bolts on the front of the lower balance shaft support and the 2 on the back of the lower support? I can’t find this info anywhere.

If you removed the covers, be mindful that there is a specific torque sequence to follow when you put it back on, and that the 2 bolts over the rear bearing may have special torque specs depending on which covers you have.
