Right hand gear change rose joints

[Alex93]

I'm fitting the roae joints for the gear linkage on the right hand side and having trouble screwing the rose joint in. Is the joint an M12 fine thread? The threaded mounting appears to be a regular M12 thread. I know there's powder coating obviously which would make it a bit tougher to screw in but it just appears as though I'm knack wrong the thread on the mounting. Any help please?

Can't remember if the threads are metric or AF.

Do remember that quite a few bits use imperial threads (usually fine) so don't assume you need to run a metric tap or die over them.

It's just that the joint is knackering the thread on the mounting that's all. Has anyone else had this problem?

From memory CJ build site had some info on thread size for the rose joint for gear linkage etc

I knackered one rose joint whilst doing that job, and put it down to powder coat in the threads. I ordered a new one from the factory and they told me the thread size. I decided to buy a tap to clean out the threads first. I can't remember what they told me but in my garage I have an almost unused 5/8" UNC tap in its box - it could be that size...

A call to the factory on Monday will give you a definitive answer.

Can you not use a hacksaw to make a cut in the end of the joint, then use the joint like a tap to clear the thread of powdercoat?

[Alex93]

I emailed the factory and they confirmed that both the joint and mounting are standard 1/2" unf thread so just needs a tap running through it.
Thanks for the help guys

A thread chaser or restorer would be better than a tap

The OP says the thread on the joint is being damaged so I suspect that the problem is a weld spatter in the thread rather than just powder coat. In which case a tap would be the better tool and even that may get damaged as weld spatter is quite hard.

I agree if it's a weld splatter then the tap

IMO the factory should check all welded threads then it could be fixed before paint, these are standard procedures for a quality build. I had a rebuilt engine once that had a bad thread on a crank and they said never checked them because they never had a bad one!

I hate threads and mosquito's

Cheers guys.
I'm going to try and pick up a tap today or tomorrow and try running it through and just see what happens.
Thanks for the help
