Push rod tube seal replacement

[davidpdx]

As soon as the outside temps get high enough to work in the garage without gloves, I am planing to replace my push rod tube seals. I am wondering which parts that I need to buy are specific to R65s and which are generic to all airheads. I am hoping that whoever I buy my parts from will know but I would rather find out ahead of time. Thanks

You could check the part numbers from the 800 and 1000 cc bikes and see if the numbers are the same as the R65 numbers .

Without doing any checking, I would say the push rod tube seals are probably the same across all three displacement bikes, along with the o-rings that seal the lower cylinder hold down threaded studs .

After that, the parts are probably different .

Pushrod seals are "generic" as is the rocker cover seals and stud "o" rings.

The head gaskets and cylinder base "o" rings are R65 specific.
 
for what it is worth Moto bins do a top end gasket and seal kit pretty cheaply.

R65 uses a different pushtube seal than all the other. Below are the numbers from MAX BMW Site.

      R65 part number 11 11 1 335 090      
       11 32 1 250 267       PUSHROD SEAL (to 08/75)      
       11 32 1 262 995       PUSHROD SEAL (from 08/75

Where do you get your parts?  I get mine from the Beemershop in CA.  Give them your VIN, they'll be looking up all the parts you need from the right diagram.  Will you be changing rings too, or just the seals and gaskets?

Thanks for all the input. I thought I would check the rings once I got a look at them and decide. The local shop wanted to replace the rings and rework the heads at about the price of what i paid for the bike so decided to do it myself. Lots of great resources on line and I have Oak's top end book so should be able to muddle through.

Don't be surprised if your piston wrist pin circlips are the older pointy type that you have to pry out with a small pointy tool, not the kind with little holes at each end for a proper plier.  At least, that's what mine use.
