Is this a complete balls up?

I've bought in a new outer CV (Metelli) and driveshaft. In my excitement and tiredness decided to put them together tonight. So put circlip on the end groove and then slotted on CV wallop lovely that was easy but now the CV slides back and forth an inch or so. Did I miss a second circlip? If so what do I do to get it off?
Or is it just not on fully?

[DILLIGAF]

I'd suggest that the circlip has jumped out of it's slot and is stopping the joint locating properly. If the shafts off the car you'll need to persuade the cv of with a BFH, just make sure you keep it all inline. I usually hold the shaft CV down and give the CV a good clout.......

I agree, most likely the circlip is out of its groove, a common occurrence, but there are a couple of other things to check too. Firstly, did you fit the CV to the correct end of the driveshaft? Secondly, is the other circlip in place, the thick square section one one that prevents the CV sliding up the shaft? These are rarely removed, and ought to be on the new shaft, but nowadays you never know....

 

See here, item 35:

Competition shafts used to have a welded on collar instead of the thick circlip to avoid a major stress raiser due to the groove for the circlip. If you go that route, it needs to be welded with low hydrogen consumables, in utterly clean and dry conditions, especially with no trace of oil, as anything which contains hydrogen will result in embrittlement of the shaft. MIG with clean wire is probably ok, but I believe they are normally arc welded with a 7013 electrode.

Firstly many thanks.

Yes it is the correct end of the shaft which came without the thick circlip (I think is called a retainer clip/ring). From the very place tiger99 linked so I guess I should get back to them?
I tried to get the cv off with little success. I believe I should use a plastic hammer? So I'll get one.
Cheers

A brass hammer is very good for that. At one time you could get a "Yellow Hammer", German I think, which had interchangeable heads, including brass, and hard and soft plastic, but they have not been sold for many years now. Sadly, mine was stolen, and I have never found one as good.

 

You could use a piece of softish metal such as ali or brass, or even hardwood, to cushion the blow from a nomal steel hammer. As I think you know, it is a bad idea to use a steel hammer directly, as you may chip the hammer, or the CV, or both.

Plastic hammer wont work that well, as your relying on the shock effect to over come the cir clip rather than the weight of the implement.........

Brass hammer sounds good I have been trying with a brass punch but no joy since I don't have a vice.

Have you ever seen this driver

 

Looks just the tool for the job but can't find one anywhere except one in America.

 

Also took a look at getting the thick circlip from Somerford but they're sold out, I don't get that since the shaft can't work without it.

 

Some available on ever useful ebay though.

 

Thanks again

  Just sounds like a Thor hammer to me, a very old English company.  I have a few sizes and have them setup with Nylon and rawhide but you can get a few different faces in several sizes.  No.4 with copper faces is a good choice.

No, not a Thor, which I have also seen, and is not nearly as good. It was called a Gelbe something or other in German, as well as Yellow Hammer in English. Probably about 1973. The handle and head were yellow plastic coated steel, with a rubber grip on the handle, and one end of the head was a large domed head on a through bolt, with a transverse hole to use a tommy bar to tighten it. That screwed into the back of the interchangeable head, which fitted in a recess at the other end of the body, with an anti-rotation pin. The heard had a largish female thread. You could hammer safely with the interchangeable head or the domed end, which was as good as any ball pein hammer, and the design allowed the interchangeable head to be secured very tightly so it did not tend to unscrew. It came with several heads, definitely brass, steel, red hard plastic and yellowish polyurethane, and about 6 other different heads were available as extras.

 

They were advertied in the motoring comics of the era, and probably sold by Halfords.

 

I guess that if I ever get my proper workshop, I will have to make one, as close as possible to the original, from memory, as nothing is like it.

 

It is unfortunate that we can't get various tools of that era now, for example an Aven Trimmatool was useful as a body file, and cheaper than the genuine article, and Abraflies disappeared for a time but are now back.
