BIS crankshaft end float asjustment
« on: January 17, 2020, 10:34:56 AM »
I pulled my BIS engine apart, glassblasted it and serviced all parts.

Crankshaft bearings were shot, so I exhanged those.

I did however forget to look at the crankshaft float before I disassembled it. How are the crankshaft hold in place? Right now there are some 2mm float :-) From the exploded view and the workshop manuals I cannot figure out how its fixed. Is it suppose to ride against the flywheel end or the timing chain end?

It sounds like you may have put the thrust washer in the front bearing the wrong way round as circled, the hole in the centre has a chamfer, which mates with the chamfer on the crank if its the wrong way round it will give you 2/3 mm float

Thx.

I hadn't mounted the washer yet. I forgot was I was looking for and misplaced in a box. Once I found it, it was pretty obvious:)

That's good news, I did it myself many years ago and spent a week scratching my head :headscratch: 🙂
