Exact replacement on AYP decks with 3-hole housings, works fine Mar 15, 2014
By Harold Melton
This fits into the 3-bolt AYP mandrel housing (128774). Has the 5-point star blade drive, which wears down if you ever let your blade(s) get loose -- which frequently happens if (when) the blade lock-washer splits and falls out. Also, if the v-pulley ever gets a bit loose, it will grind off the splines on the top end of the shaft and also on the inside of the pulley.
1. Remove the mower deck
2. Do NOT un-bolt the spindle housings, just leave them on the deck (unless you have a bearing press handy)
3. Remove the v-pulleys (sheaves), then the blades, with a 1/2-inch impact wrench
4. Drive the old shaft downward with a big drift punch (like, see Armstrong 70-197, Amazon B002FCP5WE) and a 3-pound hammer (but don't get too carried away or you'll crack the aluminum housings)
5. If your mower is like 10 years old, or has ever been stored in the rain, the lower bearing will likely be stuck in corroded housing and take a good bit of hammering to get it out.
6. Turn deck over and drive out top bearing (you really do need a that long drift punch, or a least some re-bar)
7. Important! Clean out the corroded bearing seats in the housings, where the bearings go, very well, with fine sandpaper, then grease them.
8. Remove nut and top bearing from new shafts
9. Put new shafts in from bottom; tap in lower bearings, then turn over and tap in top bearings, and put on v-pulleys with impact wrench. The top nut will seat both bearings fully in the housings.
10. Make sure shafts turn freely -- if not, you left one or both bearing seats in the housing dirty/corroded, and the bearings are in a bind. Remove, clean the bearing seats right down into the corners of the steps, and replace. Check for free-turning again. If you leave them in a bind they won't last long! You should feel a little drag from the bearing seals, but no more than that.
11. Replace blades, and use a torque wrench, 5/16x24 grade 8 takes 27 ft.lbs dry, or 20 ft.lbs. lubricated.
Remember to check your blade bolts occasionally -- if they ever get loose, the blade will grind the star off the shaft, which is much softer metal than the blades.

Good quality Jan 02, 2010
By S. Price
Spindle shaft w/ bearings seems like a good quality shaft. I would purchase an impact wrench before attempting to remove the old one. I used this on a Husqvarna 42" due to striped stars. For this mower the shaft is a little long, about 1/8" I used the old washer and added it to the top of the pulley otherwise the threads will bottom out. Nothing major, well worth the money. Shipping was ok; packing could be a little better.

Just what I needed. Mar 03, 2011
Well made, easy to install if you're willing to get a little dirty. Works perfectly on my Craftsman 42" belly mower. Highly recommend.

This worked like a charm Aug 18, 2014
By A. Lleras
I bought an used Craftsman riding mower that needed some work. I bought the shaft kit to replace the existing ones when I replaced the blades. This worked like a charm! I pulled the old parts (after getting down and dirty getting them out there due to rust and wear) and compared them side to side ant they were an exact match (length, size and threading). My kits arrived pre-lubed thus made it easier to insert. Im happy to say that this worked perfectly now my mower deck does not vibrate when I engage the blades. Also,the kit includes the bolts and washers to hold the blades (not pictured).

Freaking Awsome!!! Nov 01, 2009
By M. Hutson
Replaced because the star was stripped off. I figured I would replace both at the same time. I didn't realize the bearings were bad on the side that wasn't stripped. Mower works like new. Seems to be so much quieter now. AND, VERY fast shipping!!!
