As I attempt to find a suitable (and reasonable $) repair for the splines on a K75RT driveshaft/final drive, I’ve come across a lot of older information, so I thought I’d give a current update of where we are today (3/14/2018). Please let me know if I have missed anything!!
Brand new OEM:Buy a new driveshaft (~$365) and a final drive (~$824) from BMW
Repair:Hansen’s BMW in Medford, OR - they repair the final drive only. The base price for new pinion shaft splines ONLY is $220 if you do some disassembly work. On an older final drive (above 30k or so), they will also replace the pinion gear and seals. They also sell a brand new BMW driveshaft with a 2-year warranty (~$330 for driveshaft because of 10% discount w/drive repair).
Side note: Craig (proprietor of Hansen's) also said that he accepts final drives from BMW and Independent Shops, so if you don't want to tackle it yourself, you can have someone else do the dirty work for you. He tries to get them back out of the shop in 2 weeks or so.
Bombers Beemers in Durham, NC
They offer a full rebuild of the final drive with new pinion shaft spline, new drive shaft, clean and reseal. ($989.95 with 1yr/12k warranty - it is noted that the metal in the new drive shaft splines are supposedly better quality than original)
Used:Check the MOA Market place, iBMWR, or eBay
Check your local swap meet or motorcycle parts breaker
**I’ve noticed that the quality on eBay has not been the best, as most are used parts with significant wear. You can see that some eBay sellers deliberately choose not to show the actual splines, in an effort to hide their poor condition!!**
Other repairs:MachineService in WI - They only repair the u-joint on the drive shaft, which isn’t generally a problem on the K75/K100
Oshmo in Van Nuys, CA and Hendersen Precision in Big Oak Flat, CA - Seem to only repair /5 /6 /7 model final drives or u-joints in R100's
Motobins.co.uk Driveshaft repair - If you're in the UK, you're in luck, they will repair your driveshaft! If you outside of the UK, they will sell you the "collar" (~$77) which contains the new drive splines, but you would need to source a machinist to remove the old splines and add the new Motobins splines.
Old places no longer providing new/repairs:Brand new:
Ted Porter’s Beemershop and Bombers Beemers sold the Emerald Island (EI) rebuildable driveshaft, but they are backordered for redesign (no known date of when that will be)
Repairs
Bruno’s Repair in Canada (closed down last year)
Side note:
Grease that no longer is made for lubing the splines:
- Honda Moly 60
- Guard Dog Moly grease
Please don't post any "I have a drive shaft for sale" replies here - that's what the market place is for :)
