Help with Clutch not disengaging

[Blue_MS3]

I recently replaced my engine and upon completion I went to take the car for a test drive and could not. When I move the shifter into gear with the car running and clutch pedal to the floor it will not go unless you force it. The car begins to creep forward as soon as the shifter moves forward which tells me the clutch is not disengaging all the way. Is there any adjustment in the clutch system that would allow the fork and throw bearing to move a bit further or is it possible that the system still has some air in it? I bled the system but maybe I should keep going? I have looked for someplace to adjust it but have been unsuccessful. If anyone has any ideas or has anything else to check please let me know. Thanks.

possibly put the clutch disk on backwards, I am in the same situation with my MSP but I think mine is for a different reason

don't know if this could be your problem but i had a similar problem with my ford and the cause was the clutch spring popping out of the clutch disc

There is no adjustment on the hydro clutch in the MS3. TOB bearing could be hanging up on the input shaft also. Tough thing is, you gotta rip it all out to find out. Give another crack at bleeding the system, then crack yer knuckles and get at it, if that doesn't work.

Yeah I am going to try and bleed it again tonight, yesterday was not good we got 6" of rain so it was a soaker. I think I am going to get one of those vacuum pumps that sucks the air out and try that. Seems stupid that they would design a clutch system with no adjustment on it.

Are the Speed 3 and Speed 6 OEM clutch and flywheel the same? I think the clutch I used ended up being from a speed 6. If they are not the same then that might be my problem.

You don't need adjustment in a hydro system. It's designed to adjust itself. The 6 has an adjustable pedal and, that's something I would have really liked Mazda to keep for the 3.

Can't say if the clutch parts are the same or diff, though, sorry.

Power hydraulic bleeders are the only way to go, and an air bubble would definitely cause this sort of trouble.

Did you do the swap or did a garage?

I did the swap. I bought a motor out of a wrecked speed 6 so the clutch and flywheel was never disconnected from the crankshaft, I just bolted my transmission up. I did discover that it shifts perfectly when the car is not running, then if I put it in gear then the car will drive fine. The clutch feels like it just needs the last 1/4" to let go.
