NIVOMAT ..... Gaiters

[bob12]

What's the easiest way to put new gaiters on Nivomats? The lower end of the gaiter is far smaller than the top end and all of the new gaiter has to go over the lower bushing!

The proverbial camel and eye of a needle come to mind!

Is the only answer to soften the gaiter up in boiling water and then just plain brute force (without splitting the new gaiter of course!)?

Ideas or practical experience please

Bob.

Hi Jim ..... I got the gaiters 3/4 years ago direct from the local Volvo main dealer as my n/s Nivo was weeping slightly and the gaiter was splitting up. It's Part No.1387105 and was the only place I could find replacements. Can't find the invoice (it's somewhere!), but seem to recall they came in at about £7 each with delivery from UK stock the next day.

The Nivos in the pic are not Sachs, but Boge eXtreme (after ZF bought out those companies) which I have had in reserve and am now cleaning up for possible fitting to the 745 all as a precautionary measure as I fancy I might just have to replace one at MOT time in August!

I bought some new rubber gaiters recently from Skandix. I like the look of this method, but I’m not sure how practical it is.

Now that's very interesting. I had looked on the Matthews site but missed that. All I had found there was about 4 words saying you can unscrew them and that was all. I shall have to consider this further!

Another suggestion for you to investigate Bob - on a lot of FWD cars, replacing the CV boots often causes a problem because of driveshaft diameters and so on. I've seen plastic (Teflon?) cones used to stretch the boot over the larger part, presumably with some grease to aid slippage over the tight bits (Ooo-errr missus! ) and it's crossed my mind this might be a way round your problem.

This ebay link shows the animal in question including a pictorial method of use.

That could almost certainly be used with care on your bellows, perhaps in conjunction with a piece of pipe the right size that will go over the end of the Nivo - slide the bellows onto the cone, pipe over Nivo, slide bellows off cone and onto pipe then onto Nivo - or a variation thereof.

Thanks Dave. You suggestion might come in useful ... or I could use one of those medical contraptions for expanding certain parts of the human anatomy!! It's not a spatula but that's near enough!!

I am now seriously considering the method of unscrewing the piston as put up in the above post by Forrest. I have been in touch with 'kahl' on Matthew's Forum as to exactly what he meant by "using v clamps in a press". Is that just a vice or a side press?

Should unscrewing the bushing work it's a very neat and simple solution.

Currently, I have cleaned up the piston end at the lower bushing and it's looking exactly as per karl's photo. It's now been given a good dose of Devcon 'Twist-Off'. It's very old and always seems to work where others don't. I am sure that it wouldn't pass any H&S requirement today!!

By the way, what was that magic formula you always propound for difficult 'bit'? I have it somewhere but to lazy to hunt for it!!

Is it a speculum your thinking of Bob? Used for "expanding passages" to enable viewing usually!

Hellermann pliers are a similar device, used in electronics to fit sleeving over wires - this was in the "pre-heatshrink sleeving" days though.



I believe they're still used these days but obviously for specialist applications, squeezing the handles causes two of the legs to move outwards while the third stayed where it was so the sleeve (placed over the three legs when they were together as in the photo) was stretched to enable sliding over a wire joint then released. This is one example of their use, there are others like sticking them up your mates nostril and squeezing so his nostril was stretched!

Not that i did anything like that as an apprentice you understand...........

For fear of being redacted all I can say is that I am told that they, and 'other' implements feature on all sorts of websites.

What's your formula though for the release oil ... please?
