Product Description
For the DIY person. Warning this can be a very difficult job.
It is recommended that you remove the rotor disc from the old shaft then install the gear on the shaft before you reinstall it. To avoid damaging the new viton oil seal insert the shaft and gear assembly from the bottom after the bushing and seal have been replaced. Lastly the most difficult part is attaching the aluminum rotor disc to the shaft while the shaft is installed in the distributor.
That's how I do it here in the shop so the viton oil seal never passes over the groove cut in the shaft.
Kit includes: New Bushing, New Viton Oil Seal and Helical Groove Shaft for BMW 2000 2002.
From time to time due to increased crankcase back pressure a 123ignition may see oil being introduced into the PCB area. This condition is often caused by cracked rings or some catastrophic engine failure and must be addressed. It does not happen to all BMW.
We have modified a new shaft patterned after the original BMW shaft with the reverse oil groove. It is our goal that with this design change and the new Viton seal and bushing, oil intrusion will be greatly reduced if not eliminated. There is no guarantee with this modification.
