The Ford Barn

Doing final assembly on a #78 case 3 speed. Had new oillite bushings installed and the they were too oversized to permit the cross shaft for throw out bearing fork to go through.

Re-read Mac VP's book and he stated this could be a problem. Followed his trick of filing the slot to open them up a bit.

One side worked, the other is still super tight. I even found some old NOS Ford bushings. One side went well, but the side with the clutch arm is still not going through.

When I put the shaft into the case without the bushing, the hole seems concentric and there is no obvious reason for this to be happening.

I even tried a different shaft and same thing occurred.

When I fit the bushings to shaft out of the case, I can see the amount the shell casings need to be opened, I carefully filed, reinserted the bushing and tried again. The same tightness keeps happening.

Any thoughts on what the problem could be?

Thanks,
