Midyear Van Diemen Rear Upright Assembly

[Rick Iverson]

Gents;

Anyone have drawings or photos of the rear hub assembly as it is pieced together?

You might be better to list a year or years, mid-year doesn't really denote anything in the VD range.

inner drive flange and outer sandwitch the bearing. Remove the bolts, the inner flange will just pop out. Outer hub is a light press fit, usually putting it in a cooler with dry ice will make it easy to press out. I usually put the upright in my gas grill and put it on low and eventually the bearing will drop put on its own.

Is there a Teflon plug with six (6) holes on the GB side of the drive flange. I am converting to MS bolts, and the cost is exorbitant. Just want to make sure on the lengths.

There is a teflon stopper but it sits on the center 6 SHCS that hold the drive flange and the hub together. The bolts do not go through the stopper. However if you go away from the SHCS system you will create a problem with the stopper that will have to be tackled.

You can replace the SHCS for hex bolts - i have some inner flanges that have an integrated tripos that use hex bolts. BUT - without hex pockets machined in the flange you may find it difficult to keep the bolts from turning - not sure there's socket clearance available.

Who can supply these teflon stoppers? I did not see them on the Primus website.

With mentorship and the recommendation of Bill Dormandy, I went with MS21250-05-66, 12-point heads. These are far superior to the typical stock SHCS.
