70/71 Transmission
I have a 70/71 Transmission, and having trouble mating the engine to the tranny. The clutch release fork hits the throw out bearing and prevents the two from mating togther. Is there a trick or a simple method.
Thanks Eric |

Eric,
You need to use a screwdriver inserted through the holes in the transmission case to line up the throwout bearing flanges. The flat sides of the throwout bearing must be parallel to the arms of the release fork. This allows the release fork to slip over the throwout bearing so the tranny and engine can be mated. Hope that helps ![]()

In order to get the transmission attached to the engine you need to do the following things. First make sure that you have the throw out bearing arm on the transmission case assembeled in the correct order. There are four components in the throw out bearing arm assembly. The pivot ball, the arm, the spring plate and the washer. If that is assembled correctly, then you have to disconnect the clutch cable from the trans housing removing the clutch cable end, the trunion, and the two clutch cable bowden tube adjusting nuts. Then you mount the transmission to the engine and tighten the four retainers between the engine and transmission. You then position yourself under the car facing toward the rear and reach over the top of the transmission with your right hand and while you pull the throw out bearing arm with your left hand toward the front of the car you reach over the top of the transmission to position the throw out bearing arm so it will pass the two flat spots on the throw out bearing. Once you have reached this spot, rotate the throw out bearing 90 degrees, let go of the throw out bearing arm and listen/feel the throw out bearing click into its' resting spot.(90 degrees from the flat spots on the side of the throw out bearing that you have slipped the throw out bearing arm by. Then you put the bowden tube adjusting nuts back on the clutch cable bowden tube, all the way back, slip on the alum trunion, put the retaining clutch cable end on and place it in the allotted slot on the transmission. Position the trunion in the throwout bearing arm and take the slack out of the adjusting screws. There should be one inch of freeplay at the top of the clutch pedal at the floor board. Then tighten the lock nut on the bowden tube. OTTO

VERY important step. If no click, the throw out bearing will slide a little bit everytime you use the clutch until it realeses completely. Don't ask me how I know! BK |

I think I've heard "the click" but I am still able to move the throw out bearing from the 90 degree spot with not much effort. In vague terms, I don't hear an UNclick when I move it from the 90 degree mark.
So do I just trust that it'll stay in that same spot (the 90 degree) or, based on this description, will it slide as I use the clutch. Once I heard the click, does the throw out bearing lock in or is there still movement from there? Thanks.
