Main Shaft Bearing Retainer Plate   Price: $6 shipped
The 1973 and later mainshaft ball bearing is retained in it's bore by the nose cone casting. However, the contact area is so small, and the magnesium of the nose cone is not strong enough to prevent the bearing from pounding a groove into the nose cone. (see the pic above with the groove indicated by the yellow spots) With this damage, the bearing and the whole mainshaft can walk back and forth. In extreme cases, it will cause the trans to pop out of 4th gear. At the least, it causes extra wear on the 3-4 slider, 3-4 fork, and 4th gear engagement teeth. Every gearbox I have opened shows this problem, even those that were only used with stock engines.

Install this retaining plate to positively stop all mainshaft movement. Cut from 3mm thick steel on a CNC waterjet machine.

Can be used with the following gear carrier castings:
001 301 173
081 301 173
081 301 173A
200 301 173A
311 301 173
002 311 173A
091 311 173

These gear carriers use mainshaft ball bearing 002 301 123A or 091 301 123.

The pinion's roller bearing in the gear carrier is retained by two webs in the nose cone. These two features are only found on the late 3 bolt nose cones. If you are installing a gearbox with one of the above gear carriers into an earlier car and are installing an early 2 bolt nose cone, these nose cones do not have the two webs to retain the pinion's roller bearing. Installing my steel plate will hold the pinion's roller bearing in place, allowing you to use the early nose cone.
You can also use this plate on a Bus 'box. You will have to grind clearance on the inside of the nose cone for it.

To install this plate requires you to drill and tap a M8x1.25 threaded hole between the two bearing bores. Then use an M8 x 20 bolt and washer with Loctite.
Drilling tip: The first few I drilled, the hole ended up way off center. I realized that since the center of the hole is not on a flat surface, the drill will tend to walk to one side. To prevent this, first drill from the nose cone side with about a 2-2.5mm drill. Then flip it over and drill the rest of the way from the inside. This will keep the drill centered to your original pilot hole.

$6 each or 3 for $15. Shipping included!
