Right Part First Time
I ordered the part on Friday afternoon and it was in the mailbox that Monday. Unbelievably fast. It was very easy to look up and order the correct part too. I will continue to use your company for all my Husqvarna needs. Thank you!

The only vendor I've found that stocks the shaft independent of the mandrel assembly..
While the part was exactly what I needed, shipping was very slow, nearly two weeks. Shipping costs and the time between ordering and receipt are equally important to me from a total value of service standpoint. The cost of expedited delivery was more than the part itself, thus, wasn't a sensible option.

Worked Great
The part worked out great. Only problem was it took 1 1/2 weeks to get. Grass was pretty tall by the time I got the part.

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!

Parts Used
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.

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.
