case 310B pump coupler

[ronb.vip]

I have an abused Case 310B B/L. The Crank pulley was assembled without the four buhings in the pulley end coupler connection, the key is sheared on the crank, the end nut (square 1/2' hole to tighten and undo is ok but the pulley wont pass by the two cast pieces in front of it....so how can I put the nut back on and provide enough hold on the crank without the key that it will turn the pump,waterpump and alternator? Have to get this thing back and running. Have ordered the 4 bushings for the 7/16 bolts but need some help with ensuring that no slippage occurs between the front crank and the pulley.

Thanks a lot

You best bite the bullet and take the bracket out of the way or raise the engine to get the pulley off so you can replace the key otherwise you may have to replace the crankshaft,I think that bracket is the front engine support held on to the block with four bolts,there should be a rubber mounting in the middle,a new oil seal and mounting would be a good idea as well as the key,you may find that the pulley is a little loose on the shaft,if so put some bearing lock on it and some Loctite on the nut threads.
Good luck
