Hey Lorraine, Answers below... > Can't get the oring between tube and housing for > one...local parts don't have > it...does anyone know if the o ring is the same size > of a push rod tube seal? Not sure if it is the same size. The last time I needed one, I went to the auto parts store and purchased an o-ring of size 1 1/4" outside diameter by 1/8" thickness. The reason for all of the RTV is that this o-ring is similar to the o-ring used on later model vanagons. However, the later model is a bit smaller. I think the early ones are no longer available, so folks substitute the later ones - the RTV helps make-up the difference. The size I recommend is slightly larger than the original and causes a nice tight, no-leak fit. When purchsing, ensure the o-ring is heat resistant. > Am I going to have a difficult time finding the > upper cross over tube if I > can't bend it back into shape (at flange area)?

The tube must be loosened and pushed out of the way. It does not need to be removed from the car. I guess you could leave it in place, but then you have the difficulty of ensuring the o-ring properly seats while also trying to line up the two bolts that attach the waterpump housing. > Bently doesn't really go into > detail bout what to remove.

No, remove it. --- Lorraine Rios <Riomelillo@AOL.COM> wrote: > First of all I would like to thank all the input > from everyone on my clutch > slave replacement.
