RE: URGENT 4kQ Clutch Pilot Bearing Question

["Buchholz, Steven" <Steven.Buchholz@kla-tencor.com>]

Well, I think I found the source of my mating problems last night ...
the 4kq engine & tranny that is!

I don't know why that P/N I gave yesterday even showed up on the fiche!
That bearing is set up for a tranny input shaft that has been machined
to a smaller diameter!  No wonder I couldn't get the two together!  This
part would accept the clutch centering tool I had used before on my Fox
...

... that makes me all the more frustrated ... I've got a clutch kit
including pilot bearing sitting in the garage waiting to be installed on
the 5kCSQW ... if I would have looked into the problem sooner and
realized this fact I could very easilyhave had the car back on the road
this past weekend!  Oh well, sometimes I have to learn the hard way!

That part I got from Carlsen yesterday was $32 at the q-list discount.
I think the reason it is so expensive is that it has a very nice seal
built into it.  A careful look shows a nylon guide to ensure that the
tranny input shaft is centered as it goes into a "real" seal (i.e. it
has a spring that runs around the periphery of the seal) followed by the
roller bearings.  As you can probably tell by now, it was so nice I
REALLY wanted to make it work ... :)

Thanks for all the suggestions!

VdT!
