Re: Attempting my first build 72 K5

Thanks for this Pete.

I ended up solving the problems with the hubs and the bad threads on the spindle.

I took the bearings and race seals out of the hubs. I then started to clean all the dirt and grim stuck inside the groves of the hubs because I believe this was causing the larger gear not to slide through smoothly as it should. So I spent about 4 hours cleaning them up pretty good. I cut out a piece of cardboard to place inside the hub and plenty of napkins to catch the dirt. (see pics)

I removed the bad spindle and used a file to file off the ends of the bad threads on the spindle. That did the trick and I was able to get the spindle nuts to thread on smoothly.

So today I finished assembly the hubs and putting on the brake calipers. Doesn't seem like a whole lot, but with the amount of work I had to do just to start putting it back together it was a full days worth.


The first pic below shows how much crap was inside the hubs. I took a very small file and a small flat head screw driver to scrap everything off.. This stuff was stuck on there to say the least.. Took me a good 4-5 hours to really clean them out well. The 2nd pic is just show that I cut a piece of cut board the same diameter size of the hub and included a few paper towels to make sure none of the dirt falls in the grease. I also removed the bearings and seals, too.
