Clutch adjusting rod + nut

Post by **badfelafel** » Mon Jul 14, 2008 2:54 pm

The nut on my clutch adjusting rod is always slipping. Its an easy fix but have bought a domed nut for it. Question is... what does the domed nut do? Why will it not slip?

I had thought about leaving the nut thats there, using a spring washer and then the domed nut to stop it slipping.

All advice much appreciated! Thx

PS all... am sitting with my brand new baby girl whilst I type

The domed nut fits into the operating arm and is locked by a plain one.

I think the 'doming' helps it to move smoothly with the operating arm . Well done with new baby - home from hospital now I assume !

Are you referring to an acorn nut (which looks like a dome on top of a nut) or a nylon locking nut?

I think your talking about the nylon locking nut. Basically the nylon increases the friction between the bolt and the nut and makes it a harder to get on, but more importantly harder to get off.

Congratulations onn the baby

Thx for congrats

baby lovely and big sister (19 mths) loving her too.

Domed nut doesnt appear to have any nylon - its very smooth and shiny and has a little ridge between the dome and the nut. Ordered it thinking it would be obvious why it would help, but once it arrived realised I have no idea how to use it!

You don't need a spring washer. If you look closely at the arm sticking out of the gearbox, the front side of it has a depression around the hole - the rounded part of the dome nut goes in there. As BG says there should be an ordinary nut too that you tighten up against the front of the dome nut to stop it moving.

Exactly!

Had a go.. the nut that is there IS a domed one, it just wont stay. Will have to get the right size of nut to be a locking one. The domed one that I bought doesnt fit the rod! (Typical Morris style...). Guess will have to go making adjustments for a wee while longer!

you could take the existing one off, fit the new one (might as well use the new part) and then when that is where you want it then turn the old nut around and lock it against the new one (flat to flat)
You can use anything for a locknut, even an "acorn" nut

But sadly - Barry says the new one doesn't fit the rod !!

Yip... the rod is much thicker than my new nut! Didnt know there were different sizes of adjusting rod, but not surprised!

The Series MM cluch rod is thinner but that has a nut on either side of the clutch release arm

Do none of the nuts from that spare engine fit Barry ?
