Mandrel Assembly 587819701

Once the mower deck was removed the repair was simple. Remove nut on top of mandrel holding the pulley wheel in place and remove wheel. Remove screws holding the old mandrel assembly to the deck, make note of where the belt guides are, and remove old mandrel (blade still attached and must remove by pulling the mandrel down through the deck). Remove nut holding blade on and remove blade. Take the mandrel screws and use them to cut threads into the screw holes of the new mandrel (the holes in the new mandrel are not pre-threaded). Put new mandrel in place, replace belt guides in their proper positions, line up the holes and replace the screws and tighten firmly. The brake pad is self explanatory: remove nut and take off old brake, put new brake on and replace nut.

Set lawn tractor front wheels up on ramps. Blocked rear wheels.
Set mower deck to lowest setting.
Used wood block to secure mower blade and removed top nut on mandrel housing.
Set mower deck to highest setting.
Removed bolt below mower blade. Removed mower blade.
Set mower deck to lowest setting for clearance to tap out old mandrel.
Used hammer and block of wood to tap out old mandrel. After old mandrel is free, set mower deck to highest setting (must have about 6" clearance below mower deck) to completely remove old mandrel.
Install new mandrel into mandrel housing from below mower deck by gently tapping block of wood held against star gear. After bearing seated, reinstall top nut on mandrel and reinstall mower blade making sure blade fully engaged with star gear on mandrel.

Thanks for sending the mandrel quickly so I could get back to mowing my lawn.

I removed my deck, found that the left blades was a little harder to turn and made a roaring noise when spinning it. I removed the top pulley and then the blade. Next I removed the spindle ( mandrel ). The fall bearings had came out of the top bearing. Also the bottom bearing was bad as well. I ordered my spindle or mandrel from eReplacementparts.com and when it came in I replaced it and my blades...which it is a good time to do since the deck was already off. Reinstalled the deck and was back in business.
Thank you eReplacementparts.com

This was on my 46 inch cut Husqvarna riding mower.
Make sure to remove spark plug wire before starting any work on or near the blades.
Wear gloves and eye protection!

The mandrel broke in two places, and also the deck ripped out at the mandrel mounting position bolt holes. Removing the blade and mandrel was fairly easy since I have done this previously. This model of Husqvarna allows for very easy removal of deck assembly from mower. What took the bulk of time was taking deck to welder to make repairs to the damaged mounting holes on deck. He used metal washers then scraped and painted to match original deck. Once I picked up deck re-attaching every thing else was done within 20-25 minutes. Mower now sounds quiet and runs & cuts maybe better now then when it was new. So the lesson here is when an unusual noise starts don't hesitate investigating before continuing to operate mower.

I removed the deck completely from the craftsman lawn tractor. Removed all damaged parts from the mower deck with the necessary tools making sure to take a cell phone picture prior to disassembly. FYI, I did not realize the mandrel assembly was not threaded at the 4 points where you attach the mandrel to the deck with the washer head screws. Don't panic though, because the washer head screws self-thread into the mandrel assembly making for a very firm attachment. This project was a little more time consuming because the old mandrel assembly had sheared off at 3 points and the broken pieces under the washer head screws were troublesome to remove. Liquid wrench helped with the removal though. FYI, make sure you don't forget to put the spacer on top of the mandrel before you attach the pulley to the top of the mandrel. All new parts went together very nicely on re-assembly. I re-attached the deck to the Lawn tractor. I started the mower and it worked flawlessly.
