Shaft Assembly

The star that goes into the blade to keep it from spinning was worn out. I took the top bolt off, took the pulley off and the entire assembly came out through the bottom. Attached blades to the new shaft assembly and inserted through the bottom, put on the pulley and tightened the bolt. Voila now cutting like brand new!

1. First removed the belt cover guard by removing two 10mm bolts.
2. Removed the nut on top of the pulley using an impact gun. The immediate torque on the nut busts it free so there is no need to lock the blade in place or try to other wise hold it from spinning, as with a wrench.
3. The shaft and blade were damaged so I left the blade attached to the shaft and discarded both to the scrap pile. You would need to remove the blade first, if it is still good and will be reused.
4. Clean the area where the bearing rests before installing the new shaft. lots of debris there after 5 years of mowing.
5. Insert the shaft into the spindle housing.
6. Make sure you install the little spacer on the top of the shaft then the pulley and thread the nut on.
7. Again using the impact drive the nut on tight.
8. Add grease. The bearing comes dry. I filled the spindle with about 1/2 of a tube of lithium multipurpose grease.
9. Install the new or reused blade.
10. Install the belt guard. The center spindle had no guard.

1. Removed the mower deck.
2. Removed the upper pulley.
3. Removed the blade.
4. Removed the housing mandrel from the frame.
5. Removed the upper bearing from the old mandrel.
6. Inserted the upper bearing in the new mandrel.
7. Inserted the shaft assembly.
8. Attached the housing to the mower deck.
9. Attached the pulley to the top of the shaft.
10. Attached the blade.
11. Returned the deck to the mower.
12. Reattached the drive belt.

1. Loosened the belt.
2. Removed the blade.
3. Removed the pulley.
4. Removed the jack shaft.
5. Removed the shims using a vise.
6. Placed the shims on the new jack shaft.
7. Installed the new jack shaft.
8. Installed the pulley.
9. Installed the blade.
10. Installed the belt.
11. Greased.
12. Started to check.

1. Removed the old components.
2. Installed the mandrel assembly.
3. Installed the blade.
4. Installed the pulley.
5. Reattached the belt.

Not knowing the extend of the damage I order all new parts to build an new housing (Mandrel) complete with shaft bearings and blade. Parts were exactly the same as original and fitted perfectly. Had a little trouble getting the old one off, had to break off the bolts that took some doing, but putting the new one together was a breeze. Thanks for the reasonable pricing.

Removed Deck from tractor then replaced barings in all three towers, New Belt on deck.
replaced the steering linkage, I had one wheel spendle bent, parts not available so had to modify the linkage to take up the slack.

Replaced spindles, bearings, and retaining bolts.

Removed blade. Remove complete old shaft assembly. replaced with new shaft assembly and replaced blade and bolt.

Took old part off installed new one
