Topic: Rebuilding CB750K8 front end.

The front end needs rebuild. Steering bearings, fork seal and front tire. I figured I post some pics of the rebuilt. 

I used an all balls Timken kit.
I'll admit I had a minor screw up and did not use any spacer under the lower bearing.. The lower tree dragged on the neck so I had to trim the bottom of the neck and lower tree. 

One thing to expect is that the top timken race sticks out of the tree a little.  This made the dust cover not cover the top bearing adequately.  I ended up making an extension sleeve out of aluminum to help cover the bearing.

I also tossed in a picture of how I removed the front brake adjuster screw. It was broken and stuck when I got the bike.

It is a pain in the ass to have to pull the gauges and the headlight bucket or leave all that stuff hangin all over the place but it will be worth it come ride time.  Most of these bikes have damaged races after as little as 5000 miles.  Once the races are damaged the handling of the bike is never good.  So many guys just got used to it and don't know what they are missing.  It becomes obvious once you get all the weight off the triples and you turn the handlebars and bearings crunch, snap, and spring back to straight.

You're preaching to the choir here.  The ones in were only a little bit bad but I could feel it. Disassembly showed small dents. Irritates like heck.

Makes for speed wobbles, too! Like at 100 MPH, SURPRISE!!!!

welll...yeah!  When slightly dimpled steering  bearing races cause problems at 40mph, you damn well better not be going 100.

BTW, After the forks were going together the headlight brackets needed to be slightly respaced. I made some new top bushings out of black UHMW that were taller than the original rubbers.
