750 K2 Rebuild

(1/2) > >>

SeanFD:
Hi All,

Having restarted my stalled rebuild, I encountered some diffs :(. Help appreciated!

The bearing retainers on both front and rear (wheel and sprocket flange) wheels are siezed solid - even my attempts at destructive removal failed. Rather foolishly I sent the wheels to be rebuilt and rechromed with the bearings intact, hoping I think that the guy would remove them before doing the work - he didn't and I am now reluctant to apply too much heat to my shiny new chrome. Would the rechroming process have helped in the seizure? How can I get these off?

Problem number 2 relates to the fork legs. These were so badly rusted and pitted at the top as to be unsalvageable. I got a set of forks from a 750F super sport. Now these area bit longer than the originals. Can I use these safely?

Thanks for your thoughts

Sean

Bryanj:
Do you mean you have chromed the hubs? in which case getting the retainers out will wreck the chrome.

have you drilled out the "stakings?"

Rust at the top of the legs dont show as its under the headlamp brackets

SeanFD:
Hi Bryan

Thanks for your thoughts. Yes the hubs are chromed and I was afraid this would be the answer. The problem was the fork legs were pretty pited throughout and the chromer didn't think he could do a good job on them.

Haven't drilled the "stakings" What are they?

Cheers

Sean

Bryanj:
If you look arround the thread edge of the screwed in retainer you will see 4 points where it looks like somebody used a centre punch. you need to dill down with a 1/8 drill (ish) till you have removed the deformed metal to allow the retainer to unscrew.

Now i seem to remember that one of them is a L/H thread and i think its the rear---but dont take that as gospel as its been a LONG time.

Dont think much of your chromer if he has done a hub complete with bearing and grease in it!!

Have you tried going to a fork specialist to rechrome the forks rather than a chromer, there's a few advertise in ccm magazine, they precision grind down the forks the build them up again in a somewhat complex process to original specification
