Is it left or is it right?

Forums

Hi guys, halfway through rebuilding my '75 Mk 3 - have turned my attention to the rear wheel and hub. Now - the lockring that releases the bearings etc, my Haynes manual says it has a left hand thread BUT my original workshop manual states it as having 'RIGHT HAND THREAD' in capitals just like that. Which seems odd because ifit is a right hand thread, why mention it at all?

Anyhow, I have written the lockring off and another is on its way but I still haven't got the old one off. The wheel is set up on the bench so the 12 rubbers are facing me, the lockring has four drillings which were originally round for a peg spanner to locate into. Which way do I need to turn it to unlock it? Clockwise or anti-clockwise?

Thanks brothers.

Someone will probably tell me I am wrong but this is what I am thinking:

The drive chain pulls the wheel anti-clockwise. If the locking ring threads were left hand the ring would be continuously trying to loosen so I would think that the threads must be right hand. If they are right hand then the ring must be turned anti-clockwise to remove it.

Thanks for that Cuz, but it doesn't seem to want to move either way. Before I administer the 'final solution' I need someone who has done it to tell me for sure which direction to hammer the lockring. Cheers anyhoo.

The story here is that the original factory manuals incorrectly stated that the ring had a left hand thread and Haynes picked up the mistake. Later editions were corrected and that is presumably why they stress it in capitals, as the incorrect info has been out there so long.

Fortunately, the flange on the retainer is not all that strong and thumping it the wrong way usually only means a new ring. I remember the first time that I replaced my rear wheel bearings and cycled back to the dealer later in the afternoon to ask for a bearing retainer, to be met with "They're not a left-hand thread, you know"

By the way, it's worth inserting some rubber or packing behind the cush rubber retaining plate in the hub to stop it rattling once the drive has fretted into the ring a bit.

Thanks Richard, so the exam solution is knock the ring in an anticlockwise direction to undo it... OK, I'll progress things along those lines tomorrow - for now: a nice Shiraz.

Well that's confirmed then, a 2.5 Lb ball-pein pursuader and a quality centre punch administered in an anti-clockwise fashion has done the trick and thereby ended this thread - Richard is a guru and I salute him. The hub is absolutely sparkling now and I await (amongst other things) a set of stainless spokes from Norvil and my adventure can continue... It's great this club isn't it? Taraa. Peter.

A guru eh ? I'll have you know that I got my skinned knuckles the hard way ! I have tried to learn from my mistakes though and not break the same component twice.

Might be wise idea to scribe or engrave the direction it - so you will know next time, and it will quicker than looking back for this thread!!
