Paul Mihalka Posted November 8, 2007 Share Posted November 8, 2007 I have not seen any recommendation from BMW when to replace the alternator belt. Did anybody have a hexhead belt failure? Anybody out there with over 40K or better 50K miles on the original belt? I don't like "lifetime" wear items. I would like to know how long a life that is. Link to comment
JR356 Posted November 8, 2007 Share Posted November 8, 2007 Hi, Have heard recommendations to replace them at around 35-36K miles. JR356 Link to comment
RodB Posted November 8, 2007 Share Posted November 8, 2007 According to my R1200 Haynes manual, the schedule for alternator belt replacement is every 36,000 miles (60,000 KM's) Rod Link to comment
marcopolo Posted November 8, 2007 Share Posted November 8, 2007 The alternator belt is not a "lifetime" item. The R12RT's maintenance schedule, available as a downloadable PDF file on BMW Canada's website, says this: "12 31 657 Replacing alternator belt (during servicing)*) every 60,000 km". The R12GS maintenance schedule, also available for download, is identical wrt the alternator belt, i.e., replace every 60,000 kms. Link to comment
Marty Hill Posted November 8, 2007 Share Posted November 8, 2007 Paul, no help here. My '05 was perfect when Mark picked it up at 34k. It is now past 40k. Might send him a pm. Probably change it at 36-40 since it's cheap and easy. "He says, having never done it" Link to comment
bakerzdosen Posted November 8, 2007 Share Posted November 8, 2007 Well, according to the DVD, you're supposed to check it every 12k miles. I did that on mine and found that there was a big "bump" on it. Upon taking it off (thanks Deadboy), I found this: So, I replaced it. All belts stretch a bit, so I'll replace mine if a) I find something like that on the next one - probably caused by a rock or the like. b) I reach 36k miles on it. Link to comment
SageRider Posted November 8, 2007 Share Posted November 8, 2007 Replace every 36K per service schedule. My old one looked fine upon removal. Be careful to get the right belt. Evidently the R1200-RT and R1200-GSA use one belt and all the other R1200 Hexheads use a different belt. RT belt#: 12317681841 Link to comment
Paul Mihalka Posted November 8, 2007 Author Share Posted November 8, 2007 Thanks all! Now I have the service schedule printed out. 36K it is. I should have known... Link to comment
lthj75 Posted November 8, 2007 Share Posted November 8, 2007 Thanks all! Now I have the service schedule printed out. 36K it is. I should have known... Here is an Excel based version I created awhile back - figured you might find it useful.... R1200 Excel Based Maintenance Schedule Link to comment
mountainred Posted November 9, 2007 Share Posted November 9, 2007 Too bad my alternator went out at 30000 miles (545$ plus labor). The belt lasted longer.Warranty paid this time. Link to comment
SageRider Posted November 9, 2007 Share Posted November 9, 2007 I posted the incorrect part number above. Thank you Billy (Lawman) for catching the error. For the RT: Incorrect# is 12317681841 Correct# is 12317690571 Link to comment
Rocket_Cowboy Posted November 9, 2007 Share Posted November 9, 2007 Dealer told me to replace at 36K, we are replacing at 24K since the bike is currently in for it's annual service and 24K service. It's just easier to take the down time to do it all now than to have the bike back up there in February to do it then. Link to comment
