As I said ph1 has the thrust on #3. Ph2 has it on the rear #5. I think I read where some replacement cranks may be machined for both.

Do a search for thrust bearing locations.

IIRC new OEM cranks are machined for thrust in both #3 and #5 now.
Funny that I have never bothered to notice and check. I will on the next new crank I grab.

Phase 1 motors have 48mm rod journals wheras phase 2's have 52mm journals. You should be able to check your rods/bearings for that without the crank on hand.

ok, but all the rods are the same; its the bearing thickness that will make it 48 or 52 correct? because if i ordered a new crank, and will have to get new rods i will bang my head on the wall.
