Title: Pushrod tube replacement.
Post by: beemer on June 02, 2009, 03:34:26 AM
Iv'e noticed that the pushrod tubes on my R65LS seem to be quite rusty,i guess this is a common thing as they are located under the cylinder and prone to road muck etc,anyway,i was wondering if you have to remove the barrell completly to do this job,or can you get away without taking the piston out, by just pulling the barrell forward so that you can remove the tubes?there isn't any leaks,should i leave them be?what do you think guys,J.

Motobins lists stainless replacements for the R65.
And yes, the barrel needs to be pulled to change them, IMHO.

Might as well shout it a new set of rings and big end shells at the same time.

Personally, I'm of the "if it ain't brock-up, don't fix it" school. Mine are a bit rusty as well. Factor in all the other work you could do at the same time...add up all the time and money you might take...double it: thats what it will take! I did mine last year (pushrod tube seals) and learn't quite alot from taking the jugs off for the first time. What am I saying?
Its an "if you can be bothered" job.

I would leave it until you need to remove the barrels for another reason.

I have the stainless steel ones and they still leak like Bu**ery.  Never had them sealed since they were changed.  Probably have not got the rubbers properly orientated.

If they are really bugging you, how about painting them in situ.  Be gash, and wait till you have a amost empty tank, then lean the bike over onto one of the jugs (on something soft) - degrease them then clean em up with scotch bright and paint with a brush.  He presto.  Job done.  Now you can go out for a ride - after you have done the other side ;D

As you say they are under the bike and get covered in rubbish.

How abot a nice gaudy colour to make them starnd out - or perhaps black or silver is best.

They are genrally quite stout and take a lot of rusting through.

It might be advantageous to paint them just to stop them rusting further.

I have not heard of then actually rusting through, more usually the rubbers perish before that happens, and you end up replacing them while doing the rubbers.

Most are covered in oil anyway.
