Clutch MC seal gets stuck

[alanr]

I fitted a 'PT' branded cylinder to my +2 a few months ago. I used an ordinary copper washer, no messing with annealing, just fitted it and its fine . No leaks and the cylinder works perfectly.

Glad it worked for you. I wonder if their quality is inconsistent, or if mine was the exception, possibly made on either a Monday morning or a Friday afternoon?

If it is leaking just slightly up the thread how about trying some Loctite 567 or Permatex thread sealant in addition to the copper washer?

Yes - I suppose some sort of gap filler applied to hard surfaces might work in a lowish pressure low risk situation like this.
But wouldn't answer the question.

It's very strange.
I can't help but feel another slave is called for if you want to be completely confident.
An absolute PITA to have spent so much time and effort on a 10 minute job.

Hi
Is this a USA standard to fit banjo's to the MC and SC units of the clutch system.

My +2 as original had flared steel pipes which I have now changed to copper pipes with flares, I have never had the flared type of connection leak on any type of car.

Was the SC ever designed for a banjo fitting ?

An intriguing post especially the sticking cylinder piston I hope a solution is found as I read most of the posts on this forum to increase my knowledge and prevent any future problems.
Thanks for comments guys

I guess the same goes for the MC which has very little "landing" for a banjo.
Or maybe that helps.

Is it worth trying the other hole on the slave?

Not sure about that, maybe, but also maybe just what's popular to use these days. My 2012-built BMW motorcycle uses banjos on every caliper or MC connection that is easy visible. Not sure what it uses on the ABS-pump connections though as those are buried under the tank.

The attached picture shows both SC connections. The blue fitting is on the hose from the MC, a braided type that uses a banjo at the MC connection, supplied by one of the US usual suspects (probably Dave Bean but it's been a few years so I'm not certain). The blue part threads into the SC and into a threaded fitting on the hose. There is an aluminium washer between it and the SC and that has no problems with leakage. The banjo is on a hose that goes up the firewall to a remote bleeder, an idea that I got from this thread:

Maybe I should switch it to a fitting like the blue one. I'd been ignoring it's leak-free status (squeaky wheel type of thing, you know), but maybe that would solve it. If I were to try this, anybody know what thread/connector type I would need to specify for the hole in the SC?

I hate to say it but once again OEM is best. Ford OEM (not sure about Lotus) is a flare connection directly to the slave cylinder and flare connection directly to the master cylinder. Only that method presents the minimum amount of possible leak paths. That's what's used in the brake system to connect wheel cylinders so the clutch system should be no different.

I suspect that the banjo isn't quite big enough to get a good seal withe Dowty washers.
Dud you try copper on it?

Copper washers do the trick.

[MarkDa]

Great - at last

[gjz30075]

Mark, I'm just posting an example of copper washers in this application. Hopefully this will help
