Jack shaft was bent and housing was cracked
I removed jack shaft and the housing with socket wrenches and open end wrenches. Cleaned up the deck where the new parts would be installed. I had to tap the four holes in the new jack shaft housing,, because the four holes were not tapped. after tapping these four holes I mounted the housing on deck, and,, secured it with the four bolts from the previous installation. I slipped in the new jack shaft and mounted the drive pulley. I did grease up the new assembly as well.

Repair Difficulty:
Medium
Time Spent Repairing:
1-2 hours
Tools Used:
Pliers, Socket set, Wrench Set, Adjustable Wrench, Had to use a pneumatic impact wrench to remove the spindles
Noisy when blades were engaged. Excessive vibration from deck when engaged
Removed the mower deck from mower. The mandrel spindles simply unfolded from deck with help of impact wrench. Replaced in that order. Replaced pulleys. Be careful not to lose the spacer bushing for the idler pulley! The new mandrel spindle bolt holes were not threaded. But the weight that came out of them were tapered fine threaded bolts that will simply thread themselves into the aluminum mandrel spindles. I highly recommend going to a special you faster shop to replace all the bolts that go into the mandrel spindles. It was worth the extra $12!

Jack-shilf bearings & shaft wore out, the blades were bad, all new parts purchased fit great.
I used my 2 ton engine lift to raise the lawn tractor mower front end high enough to do the repair job easily. 3 of 5 screws attaching jack-shaft to housing broke. Could not remove the spacer from old main shaft to replace with new shaft. Hardware store for new screws, I had metal tubing on hand to make a new spacer. This old machine is working again.

Thanks, for having all the parts I needed.
