I've installed a couple M5OD 5spds but I do have a continuous vacuum bleeder which makes things like brakes and hydraulic clutches much easier to deal with.

I've installed a couple M5OD 5spds but I do have a continuous vacuum bleeder which makes things like brakes and hydraulic clutches much easier to deal with. I have bench bled the MC (twice) then bled the Concentric bearing by gravity (twice) by opening And closing the Bleeding screw while someone keepers the reservoir full. Tried this method by pumping the clutch and also without… Tried to aspirate bubbles through the MC reservoir. I have half a clutch that stays midway after pressing fully and then releasing. Forgive my ignorance: What is a continuous vacuum bleeder ? Is it the gun like contraption? Link to comment Share on other sites More sharing options...
Rembrant Posted January 18, 2023 Share Posted January 18, 2023 Forgive my ignorance: What is a continuous vacuum bleeder ? Is it the gun like contraption? I call it a continuous vacuum bleeder, but it's a homemade affair. I put what is called a vacuum ejector on the cap of a pickle jar and connect a compressed air line to it. I then have a line I can attach to a bleeder screw, and then it applies full vacuum for as long as I need it to, hands free. I saw one somewhere...forget where now, but just made a cheap copy. I use it for brakes, hydraulic clutches, etc. It makes things much easier when working alone. Have you adjusted the master cylinder pushrod?

The MC pushrod is non adjustable unlike the 84 and up. I wonder if I have to have a MC for a 84-86….. Link to comment Share on other sites More sharing options...

I wonder if I have to have a MC for a 84-86….. The factory pushrods were not adjustable that I'm aware of. The only adjustable ones I've seen were the aftermarket ones that come with some new MC's. I'm not familiar with the '93 up master cylinders. I think they're different than the 84-86, and 87-92 versions. I'm sure the bore/stroke is the same, but otherwise they are different. Of the two M5OD swaps I did, I used new 1984 replacement MC's both times, and ordered the slave cylinders and hydraulic lines for 1991 models. I don't know if it makes any difference or not.

SUCCESS AT LAST!!! The issue was with the stroke length of the pushrod! I installed the original 93 MC and an aftermarket adjustable pushrod. After some trial and error with the length of the pushrod, the transmission shifts nicely now and the clutch pedal returns fully when released. This was a huge learning experience with some very frustrating segments. With all the information on this thread and all the lessons learned, I highly recommend the transmission swap as the truck feels a lot lighter now! Thanks to all who chimed in, couldn’t have done it without all of you. Link to comment Share on other sites More sharing options...
