When I read this I thought "OMG, I didn't put these in when I did a
gearbox/OD rebuild a few years ago, is that what causes the
notorious jumping-out-of-fourth problem?!" So I checked my parts
catalog--aka the Moss catalog--and didn't see them listed in the OD
sections, but I did find them in the 'Internal gearbox, 4 speed'
section showing the mainshaft assembly as 'plate, spring bearing'
and 'plate, bearing,' but only for the pre-BJ8 cars on the front of
the gearbox (by the first motion shaft). So, did I miss something,
as I don't recall ever seeing them in the OD adapter in 2 rebuilds
(the catalog doesn't show them)? <br>
<br>
For the BJ8, the catalog shows 2 available shim sizes, in lieu of
the bellville washer and 'plate,' I presume, but I installed DWM's
'uprated' shim and had to have the bellhousing machined
appropriately.<br>

Those "rings" are the Bellville washer and shim that go into the

Hi. All</div>
<div style="font-family:inherit;font-size:inherit;color:inherit;background-color:transparent">
I finally figured out how to get the OD out of my BJ7. Now for
getting the new one installed. I found two rings sitting on
the output shaft which I believe are fitted to the adapter
plate. (See pics attached). The problem is going to be how to
keep them in place while maneuvering the new OD into place. I
was thinking of using either white lithium grease or wheel
bearing grease. </div>
<div style="font-family:inherit;font-size:inherit;color:inherit;background-color:transparent">
Any suggestions? </div>
<div style="font-family:inherit;font-size:inherit;color:inherit;background-color:transparent">
Thank you in advance for any help you can offer. </div>
