clutch cylinders

I have found it is a Dolomite master cylinder, see here for a link to replacement unit or seals.

thanks very much! this may well come in handy when/if it comes to rebuilding the thing

A bad pic, but Mud has one of that type & has had for a few years now- works fine.



There was someone selling them on eBay (as Triumph) for not a lot at all, I nearly bought one for the Mk2 but decided to fit an original type instead.

i got a call from the garage today- neither cylinder has any visible signs of leakage- and when bled there was no air displaced, nor was there any change in the pedal.

it has lead him to deduce that either: the clutch cover is knackered or the clutch fork is bent/ worn out

he's going to drop the gearbox to investigate further.

he also reckons there is some oil leakage from the rear of the crankshaft- which i understand is par for the course with an a series- but, since its leaking, would it be worth fitting one of the upgraded "proper seal" kits that i have seen available. the chap reckons if its worth doing, its worth doing now while its apart anyway.

TIA

The clutch fork has a natural curve set into it, so don't be fooled by that. My bet is that the friction plate is stuck to the flywheel, that will lock up the whole drive train.

Is there any resistance in the pedal at all or does it go straight to the floor? When the clutch was bleed did fluid definatly come out? If it did you must assume the hydralic sytem is bled correctly if the fault is inside the bellhousing as you suggest you will be able to see the pushrod/ cluch arm moving if it is moving fault is in bellousing ie clutch or related components if no the fault is hydralic if so and no obvouis signs of leakage I would suspect a master cylinder fault.

I see Chris has replied at the same time thinking about it if there is pressure on the pedal I suspect he is correct. If the cover had worn through there would be horrible noises coming from bellhousing when operating the clutch with engine running it may even make it feel like brake pedal ie solid as it pushes the arm as far as it can go locking system up completely.

its not so much that it wont go into ger, more it is reluctant to.

i think its probably worth further investigation anyway. while hes there he's going to replace the seal in the tail of the gearbox, which has been weeping for sometime.

it would be strange if the clutch was stuck- it had done a near 100 mile journey a few days before, and had only been sat over night for 2 days- i was under the impression clutch plates stick over a few months not a few days.
