Club 80-90 Forums

I know there is a lot of experience on 80-90 so I hope you don't mind me asking;

I've had to remove the oil tank on my bike to get at some of the 'leccy parts. The manufacturers manual is insistent that I replace the clic hose clamps with clic hose clamps and DO NOT use screw hose clamps (Jubilee type). I've never had a problem with decent quality screw type clamps but, what do you think?

Cheers,
Ian

Usual issue with J clips, is that they don't expand and contract with the engines heat. Thus a J clip is wound up tight to stop leaks when cold and is potentially over tight when the hose heats up. The metal doesn't expand as much as the hose. When I did my engine rebuild I went for stainless J clips, worst decision! Slowly changing them all back! Just my tuppence....

^^^^^^^^^^^^^^^ Exactly that. I use to work for a company that designed and made thermostats for cooling systems. The thermal cycle test rigs originally used J clips but the rubber hose would extrude out from under the J clip and the hose then leaked; tighten it up and the cycle was repeated until the hose was almost cut through.
The spring clips move with the hose but they do have to be the right size. And they hurt when the twang out of the pliers!!

OK, cheers. Just gives me an excuse to buy some new tools!

Out of interest where are you getting the clic clamps from. I binned mine from the radiator for jubilees and they both leak.

That's a good question, any recommendations anyone?
Not got that far yet myself, I will probably ask for recommendation of where to get them on the Aprilia forum. Will let you know.

I often wondered why vehicle manufacturers (incl our T25s) used those (damn) hose clips that need(ish) a special tool and even then can be a right pain to deal with. I have gradually replaced all mine with J clips

i find long nosed mole grips works best at removing/installing the spring clips. There is a special VW tool for them if you can find it!

You can pick the tool up from ebay etc.

£15 ish, either hand/plier type ones , or aratchet style handgrip with long (half meter) flexible line with inner with clamp on end

Advanced Fluid Solutions have them in stock http://www.advancedfluidsolutions.co.uk ... -128-c.asp" onclick="window.open(this.href);return false;

Two factors... The constant tension vs constant diameter side is one. The other is that they're a LOT easier (=cheaper) to install on the production line...

I'm going on the basis that none of the originals leaked but the replacements do. I generally use plumbers grips but should I be using something like this:



although I can't see just by looking at the picture how it would work!

Looks like something that'd normally be used for...


Seriously, I suspect that once you'd tried that, you'd want to gold-plate it and put it in the position of honour in your toolbox. The remote end allows you to work in a confined space, the handle end allows you to get a decent grip and squeeze.
