Fork oil replacement

[disco51]

Thanks for the help.  I did buy the Clymer's manual, which has been helpful.  It's a 79' with over 30,000 miles.  Have no idea of prior maintanence performed.  
I did see some rubber chunks when I drained the fork oil.  Guess I could try the overhaul.  I didn't notice any clunks when riding.  I'm guessing I'll need to order the rubber bumper since I live in Augusta, GA with no BMW dealer nearby - where is the best place for online parts?
I'll try the wooden wedges tonight.
Thanks again.

Torque for the fork yoke clamp bolts is 29.5 - 33lbft. I use the lower figure or maybe a touch less.

Success!  I got the Allen bolt loose w/ a socket wrench.
Monte, my bumpers looked just like yours did if not worse - guess I need to find a part number and a place to buy them online or a suitable replacement.  THey are disintegrated.  I'm guessing there job is just to prevent complete bottoming of the fork?!
I left the stanchion attached to the triple clamp so far - will see if I need to use the wooden wedges.
thanks again...

The last pair I bought from Motobins was a white-ish nylon.

Remember Benjamin Franklin's Advice to a Young Man- "In the dark, all cats are gray."
Unsure if he was referencing BMW parts.

I also bought the white nylon ones from Motobins and although they will probably last forever in my opinion they are too hard to work effectively in cushioning the forks topping out. Rubber of any colour or description sounds a better bet even if it doesn't last as long.

I am going to tackle my fork seals, and fit gaitors, so I figure I better order these bumpers as well.

Is this the motobins part you guys are referring to?



They list it as BMW p/n 31 42 1 231 314 where as Bob's diagram lists 31 42 1 237 215, maybe its the difference between nylon and rubber?

[Barry]

That bush is definitely from a different type of fork and the dimensions are wrong. The picture below is what I used. Motobins don't list this as an R45/R65 fitment, in fact when looking for fork parts in the UK you will find almost nothing and soon tire of seeing the phrase "Not R45/R65"  In spite of that the 29020 bush is identical in dimensions to the original black rubber bushes and they fit OK. I would prefer rubber ones if I could find them.

What I didn't do because there isn't one near by is check to see if the BMW dealer had the rubber bushes which seem to be available easily enough in the US.

OK, thanks Barry, I see that part you used on the motobins site and its named FORK UPPER BUMPER BUSH, which kinda makes sense based on Bob's diagram.

Yes I noticed ( I checked Motorworks also) that finding any fork parts listed specifically for the R65 is impossible.

I hear what you are saying about rubber v nylon, however, as I am ordering Gaitors from Motobins I will probably throw in 2 of these as well, also I'm lazy ( and cheap), so if they last forever, that'll do me,

Mike, You've pretty much described the membership requirements for the Airhead Beemer Club. The other requirement is a fondness for barley therapy.

Well said there Monte. Whether its the fermented brewed variety or the single malted distilled version, barley therapy is the way to go!

Fermented brewed works for me, looking forward to my Blue Moon this evening. Oops we may have strayed off topic,

You have Blue Moon in Ireland? One of our house favorites here.

Might I suggest you look at the youtube video of Chris Harris's "R65 Fork Disassembly" for some nuggets of wisdom. While his language is somewhat  salty, his information is useful.

Oh, yeah, barley pops are a requirement when working on these beasts.

Well, barley therapy after a job completed will do that to you.

Since the Disco Kid got his project handled I see no harm nor foul.

Wavy, how about wrapping up this thread with a photo of your '47 Salbury scooter?
