Product Description

?

This OEM mandrel assembly is a genuine replacement part sourced directly from the manufacturer and is designed for use with riding lawn mowers. Sold individually, this tall-style mandrel includes the housing, shaft assembly, bearing, and nut. Please note that the pulley, washer, blade bolt, and washers are not included. The mandrel is the component to which the mower blade attaches and is mounted to the mower deck using four bolts. The mounting holes on the mandrel are not threaded; however, the bolts used are self-tapping to ensure a secure fit. For proper installation, the spacer must be positioned underneath the pulley. Installing the spacer on top—or omitting it entirely—can result in damage to the shaft and pulley. The mandrel shaft passes through the deck, where the pulley is attached, and the drive belt is then routed around the pulley to power the blades.

Mandrel assembly
recieved part ordered, was exact match as original. I think on your shipping options should add USPS priority mail. This method would get the part to customer in 3 days. I chose lest cost shipping and this method said would take 4-8 business days(arrived in 6 business days) for $8.47 I think. Even if was couple more dollars would have been worth it to get part in 3 days. Just something to think about. I will still use your service for addirional parts because I like the fact it gave me a coumplete layout of deck with all parts numbered and labeled. Made choosing the right part very easy.After getting part had mandrel replaced and deck back on mower in about one hour.Thanks again for having exact parts

The original mandrel assembly cracked badly around the screws that hold it to the deck, and the brake arm was bent and no longer contacting the pulley

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 d eck). 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 hit my water meter and bent the deck a little. I was able to straighten the deck and when I turned the blades back on, the left pulley started smoking and it felt like the deck was vibrating apart.

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 eReplacem entparts.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.

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 scre ws. 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.

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.
