Hello all,
I'm in the process of changing a worn taper bearing on the drive shaft of my BF130 and I have a couple of questions so hoping you guys can help.
The first question is I suppose more clarification/a second opinion regarding selecting the right shims for the drive shaft taper bearing. I've followed the service manual and have the following numbers and calculations:
Engagement mark on the case = D
(Distance D) Drive Shaft 158.9mm
Taper bearing outer race to inner 21.5mm
Taper bearing outer race 17mm
21.5mm -17mm = 4.5 (Distance E)
D+E-162.95=0.45
If I cross reference my calculation of 0.45 with case marking D on the pinion gear shim selection table i get the value of 0.40mm so therefore I should need shims C 0.30mm and A 0.10mm?
The next question is regarding the needle bearing that's in the case above the pinion gear. The underside of the original bearing was not level with the bottom of the gear case. Should I put the new one level with the bottom of the gear case or in the same place as the original?
Thanks.
