Re: Blue K/5 K/10 Spicer hub dial restoration
While we are on the topic of Spicer hubs, there are a couple of points to be made here with my recent experiences:
My inner hub clutch ring was worn and would not allow smooth locking engagement. Fortunately there are a few NOS on Ebay at the moment. Once I installed the new part, the hubs engaged flawlessly. The bushing on the inner circumference was mostly missing.
Make sure that you have all 12 (6 per side) of the small copper sealing washers 650595 for the Allen head screws on the outer chrome hub ring (retainer plate).
Also, I made a lubricant just for the hub parts. I mixed Amsoil gear oil with some synthetic grease. If you use straight wheel bearing grease, the hub parts can stick and you are looking for smooth engagement. Dana specified the use of Moly XL hi speed grease on the hub parts, and Parker O-ring lube on the control knob o-rings.
