I don't have a Midget but this looks like a good tip. See 1:50. 5:25 Not sure about the tip at 2:50?

Can you not gravity bleed a Midget clutch?

I had to do this at the end of my rebuild. Bleed it like you do you brakes. BUT hold the last pump, then push the plunger in the bunge hole to push out the bubbles trapped in the housing. Lastly tighten the bleeder.

You can gravity bleed, but the upper piping along the firewall holds air and it's really hard to remove it unless air pressure is applied.

I feel your pain. As I was bringing the 74 back up I had the misfortune to replace the flex hose to the slave, then shortly after the slave itself, then shortly after that I had to rebuild the master. Each of these required me to re-bleed the system. Add to that the transmission mounts were shot (and I didn't know it) making the slave bleed screw almost impossible to get to. After about two weeks and spending many hours crawling around under the car I finally got it bled.

Don't give up! You'll get there. If I were closer to Missouri I'd come over and we (and a few beers) would get it done.

Anyone closer that could give a hand?

Carver, we haven't heard from you about the issue. How's it going? You may have a forum crew there soon!

I had exactly the same problem, tried the Gunson - no luck. Then I had my wife pump the pedal 10 times while I held a spanner on the union on top of the master cylinder. After 10 pumps she held it down and I loosened the union half a turn. There was a loud 'pop' as the air bubble in the union was expelled. Did that twice - perfect clutch.


The trapped air bubble will simply bob up and down in the union when using other methods.

let us know how you get on.

Best of luck!

@Chas 906, we haven't had time to work on it recently, we were supposed to go work on it yesterday, but plans (sadly) changed and we are now scheduled to work on it this Sunday. And oh man, having a crew of experienced MG owners would be amazing... One more weird thing about our Midget is that there is a metal cord/wire hanging down from the undercarriage. I can post a pic if that helps. Any ideas?

Ya, sounds like the ground cable. About an inch wide 1/8" thick and braided?

If I remember correctly the loose end with the hole in it should mount under the nearest bell housing (tranny to engine) bolt.

Secure it with the least amount of loop hanging down. You don't want it to snag any road debris.

Chuck,
Some parts of 1500 Midgets are much, much different than your 61. So sometimes your well-meaning advice can be confusing or unfortunately misleading.

In this thread, for instance, the recommendation of installing a remote bleeder hose doesn't apply. The slave cylinder is very different and located on the other side of the engine with a semi-flexible line.

Also, the cable hanging down from a 1500 is likely the engine restraint system, often not reconnected when re-installing the engine. (its a pita to install).

Some of your posts ARE helpful, but your experience with your year does not apply to the engine, transmission assemblies of the 1500s.

I mean this kindly. I hope you understand.

Thanks Peter. I'm fairly new here and didn't realize the misinformation given. I'll stick to the MK1.

Let the slave cylinder hang down under the car for some time (HAVE BEER) then put it in place this is what works best unless you have pressure from the reservoir assisting the fluid through he pipe to the slave cylinder.

Cheers
