1967 K20 Adjust rear wheel bearings after new seal install

[Jason Banks]

Does your HO52 still have the barrel shaped rear bearings?

I recently replaced the rear bearings on my 1967 K20 with the tapered bearings that are more common today. I treated them like I do other tapered roller bearings, where I tighten until hard to turn and back off some to free turning.

I think the service manual procedure is for the factory type NDH Barrel Roller Bearings. If you look at the bearing itself, the bearings are barrel shaped and not straight cylindrical. If you look at the race the bearings ride in, it is concave.

Have you discovered Torque King for parts for your truck yet?

Here's a link to their bearing set they sell, but I have called them a couple times and they have been very helpful.

If you read their descriptions it talks about the NDH (New Departure Hyatt) bearings.

Have you discovered ChaparrallMan1974's build thread yet? He recently went through his whole chassis.
