Topic: checking on direction

[mark52]

Hey all, before I mess up another hub  I would like to make sure of which direction you need to turn the rear bearing retainer to loosen it up for removal. The retainer I am talking about is the one in the hub, not the drive flange, and is Honda part number 41231-300-020. Oh yeah the bike is a 1975 cb750k. And hey, if you want to offer any sure fire tips on how to get that thing out I'm all ears. Thanks

Lefty tighty, righty loosy.

PB blaster in the threads overnight while the rim is on a table.
drill out the punch marks
use a punch in ONE of the grooves and whack it clockwise (you'll mess up this groove, but not to worry)
OR
fab a bearing retainer removal tool (do a search, many home made ideas here)
OR
get a Pin Spanner Tool to fit in the retainer holes
OR
stick the tips of needle nose pliers in the retainer holes and used something to turn the pliers...

clean up the threads before you put it back in.  re-punch so it wont spin out.

STOP!
That retainer has a LEFT hand thread.

Sorry, Deltarider is right.  I pulled up a front bearing retainer.
for the rear, its left handed...

Thanks flybox and Deltarider.  I have drilled out the the punch marks or stakes, and have shot pb blaster on the retainer just about everytime I walked by it. Given how I mucked up the first hub I was sort of just hoping the ring would work itself loose with all that blaster on it.  A question for Flybox, while I think you edited the first line of your reply,  should the fourth line state "use a punch in one of the grooves and whack it clockwise (not counterclockwise as stated)"?  Also, in reading through some of the stuff on here people have also suggested warming the hub up.  For anyone who has done that, would you mind relaying how you did it and how it worked out.  Again thanks for everyones help

Actually it can be a rotten job. I had a friend do it for me. He made a special tool and he heated it up using a little flametorch. Are you sure the bearing is bad?

[flybox1]

the retainer is replaceable, and in a few cases, comes out with difficulty.  I have made tools like others here have done.  Bought a $30 pin spanner, and a $8 assortment of punches from Home Depot.   the punches come out first.   I did front bearings last weekend on a used front rim. This is what i pulled out.  yes, a punch will mar up one of the little retainer grooves, but you'll only have to replace bearings, with sealed ones, once.  I just used a file to repair the marred top of the retainer.
