Default LT42 Mowing Deck Spindles Issues

chased the part # to an aftermarket and same exact part # BUT the spindle and pulley are not EXACT copies, the net result was the pulley is about half a pulley too low causing the belt to rub on the spring and the brake rod so...

Has anyone tried removing the pulley and inserting a spacer/washer to raise and better line up the pulleys with the deck OR

Should I just source and find a four set of new bearings for the old spindle and rebuild what was on there? Model # 13AOA1CS056 2018 Build LT1042 Mowing Deck CC spindle part # 918-06976

Any advice/help/assistance is appreciated, I am trying to help a client that tried doing it themselves and got stuck. I am inclined to suggest rebuilding the old spindles with newly installed and greased bearings, does anyone happen to know the correct part number for these spindle bearings?

Rebuild them just take the whole package to a reputable bearing seller , they will identify the correct bearings
Odds are the bearings you get will be substantially better than the existing ones
Just remember on the rebuild to pull the inner seals from the bearings so the grease can get in
I rebuilt a spindle and installed "Timken " bearings , it is about a thousand percent better than a replacement one

Default Thank you

I was able to source four new bearing sets for the spindle pulley and will rebuild Friday. Not sure if they are Timken bearing or not but I am familiar with that brand from working on Sears Garden Tractors and attachments.

A local Cub Cadet retailer actually had the exact parts I needed in stock and available, which always makes me nervous.

Thanks for the reminder about removing the inner bearing seals, will do!

Hi Oz, I just bought a LTX1046 with one rough spindle. Amazon has a set of 6204 Timken's that are suppose to fit. Not sure if the spindle is OEM or aftermarket. Also will need a new pulley as it's spline teeth are rounded.

Question about removing the seals.

If I remove the inner seals, then pump it up with grease thru the zerk.. how do I know when to stop? I wouldn't want to blow out the outer seal or curl the spring loaded lip of the seal around either shaft. Curious on your input. New member to the forum BTW.

The book says you will hear a cracking/clicking type sound , injecting grease through any grease nipple/zerk is always a bit hit and miss unless you can see the other side
When assembling put plenty of grease into the housing so it will not take many squirts to fill
Every mow I give my spindles 2 pumps from a lever grease gun has not given me any grief yet
Only one spindle failure in 25 years and I put that down to dodgy China bearings

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
