47 H water pump

How do remove the adj. pulley from the H's water pump? Mine is cracked and I want to replace it. Also when I replace the bearings and seals etc. should I replace the spacer betwwen the bearings? Thanks DTK.

Once you have the hub off of the spindle, remove the seals, bearings, and *re-useable* spacer. There is a pin about 1/8" in diameter that holds the fixed part of the pulley to the hub. It is at the transition between the smaller generator pulley and the other half of the fan belt pulley. Drive this pin on into the ID of the hub. The fixed half is a light press fit on the hub. Now, you can change the broken pulley half. Assemble in reverse order.

Notes: a) When you remove the hub from the pump housing spindle, check the felt dust seal that the end of the hub turns against. It is still available from Case/NH and should be in place when assembling. b) If the packing nut has less than 3 threads showing, purchase packing (again, from a CNH dealer) and put it in. It will save you time and trouble later.
