MTD 990 Kit

This was posted on FB marketplace in the Detroit area. The owner offered to exchange halfway. About 1hr 20mins drive. This was a restore project that the owner lost interest. Everything but a seat and seat spring. This was a working tractor used to mow the Wayne State Univ. campus.

3pt hitch, good tires, good dash tower, engine honed, carb rebuilt, mower deck is nice but needs spindle bearings replaced.

1979 with a 1978 engine. Stickers are still on the dash tower.

$150 for the lot. Needless to say I am delighted.

Re: MTD 990 Kit

The 50" deck is not as nice as it looks so it is parted out.
The blade baffle is gone, the gear box is cracked on the top side, and two of the three blade spindles need bearings. I will replace the bearings and sell the spindle set. Will sell the idler pulleys also, which are tight.

Re: MTD 990 Kit

Found the spindles to be unobtainium. MTD part number 741-0211 or 941-0211.
So the spindles are scrap.
Looks like the bearings may be pressed into the outer shell.
Anyone ever try to press the bearings and spindle out of these?

Re: MTD 990 Kit

Ive never had one apart so cant help ya there... but I have 2 or 3 old rusty 42" decks that I got from littletractorguy... if they have the same spindles I Might have a spare. I just recently put my Columbia deck on the 960 that I got from him and was surprised how quiet it is so I dont think I need any parts off those spare decks.

It may be possible to find some modern and readily available spindles/pulleys/blades and modify the deck to use those.... bit of grinding/welding involved but Im sure it wouldnt be too hard to do.

Re: MTD 990 Kit

I already have a nice 50" deck so I will just keep some of the spares and sell the extras.
My deck has easily replaceable spindle bearings.

Re: MTD 990 Kit

The deck spindles do not want to be pressed apart so they are in the scrap pile.

Both drive shaft u-joints are bad. I do not like that task.

The charge pump makes a noise I never heard before. I can hear the 6 carrier rollers clicking as the shaft is rotated by hand. I am not sure if this a bad thing.

Re: MTD 990 Kit

Are you sure the spindles press apart? For my Gravely zeroturn (which Gravely would prefer I buy whole new spindles for when they wear out), my dad figured out that the spindle shaft was screwed together (like a nut & bolt, just without the hexes), with a dose of red loctite to require heat to get it apart. Saved me a bunch of money by just replacing the bearings...

Maybe use an angle grinder with a cutting wheel to cut one of the old spindles in half (in the direction the spindle is) and see how the spindle goes together?
