I know, a boring on-topic technical thread...
While replacing the paralever pivot bearings on my R11 (at 15,000 miles) last week, I discovered oil around the pinion shaft area. It was obviously gear oil, leaking from the pinion seal- the swing arm housing was bone dry and clean inside, so no way that it was coming from the transmission. There wasn't a lot- I'd guess maybe a tablespoonfull or two, pooled in the final drive and dispersed around the boot. There was oil to the plug, so maybe it got slightly overfilled when I changed it over to synthetic at 12,000 miles earlier this year. May not be a serious leak, but it should probably be addressed
I'd like to replace the seal myself. I saw that Anton cautioned against that in
this thread but then I found a
how-to thread on advrider.com, describing a procedure. Having worked on a lot of 9" Ford differentials, and having lots of fancy tools that I need to justify owning, I feel confident that I can do this, especially if I take my time, remain sober, control my ADHD, etc.
So. What's stopping me? Lack of one specific tool. Specifically, BMW "pin wrench" #33 1 700. The guy who wrote the advrider.com thread made his own. I have enough fab equipment that I could make one too, but if it's cheap enough I'd just as soon buy one. So far I haven't found any on line, though I'll confess to not having called a dealer yet either. Still, I figured I'd ask in case anyone has a better idea.
Flame suit on...
Thanks, guys.
