One of my riding buddies has a '14 RT (55,000+ miles) that just had an alternator fail and has cost him over $3000 (parts/labor) to repair at the dealer.

The largest sample size will be the GS and alternator failures seem to be reported very rarely on the UKGSer forum. Whilst the GS and RT alternators might have higher outputs, they are likely made in the same factory in China or India as those used on the R/RS.

Zitat von Lee im Beitrag #3 It's a shame as I have dealt with this particular dealer for 37 years, through several location changes and owners. This would definitely not have happened at the original store/owners. Corporate ownership with almost 50 locations sure changes things. Larry is a close friend and riding buddy. They did give him 10% off on parts. BTW they gave him a 1000 mile warranty- not even the understood (by me) warranty of 1 year on parts/labor. I have known their master mechanic/tech for all those 37 years and trust him but he can't control what the higher ups do. Frank PS- I am not concerned about my alternator failing, but if it does, I would be very willing to tackle the job myself. 2017 R1200RS- 49,000 mi. 5 yrs. |

Zitat von Duckbubbles im Beitrag #4 alternators are one part of the bike that can usually be fixed by a specialist auto-electrician - I have a place about 6 miles away

Zitat von wessie im Beitrag #5Zitat von Duckbubbles im Beitrag #4 It still has to be removed for repair- that's the rub. Frank 2017 R1200RS- 49,000 mi. 5 yrs. |

An alternator replacement on the LC boxer is a major job. The alternator is where the clutch used to be on the air-cooled boxers. The engine and gearbox would have to be separated for access. Parts and labor costs would be huge. Better not to think about an alternator failure and just trust that it will last forever.

Zitat von Mr. 36654 im Beitrag #7 Talking automotive alternators- go to your local auto parts house and rebuilt alternators are an option. I have rebuilt the alternator in my '85 K100RS a couple of times. It involved bearings and brushes/regulator. I'm sure the external alternators on previous BMW's can be rebuilt. There is an alternator/generator rebuild establishment near me, too. I would bring my external mounted alternator to them to see if they could do the job. Not trying to start an argument, just sharing what my experience is. Frank

No Argument. In some cases, alternators are rebuildable by a local electrical motor shop. I know my mid 80s Celica and 91 Delux (pick-up) had rebuildable alternators. As for US Big 3 vehicles, places like NAPA and such had a ready supply of rebuilt units. The EOM units weren't intended to be rebuilt, so the "rebuilders" scavenged what they could and replaced the rest. In my area, the parts rebuilders weren't great employers and there was preference to avoid their products, if possible. But, the rebuilt units were a lot cheaper than buying new.
