I'm just curious where the deals are for spindle bearings, I tore apart one of my extra decks tonight as I think the one I'm mowing with will need rebuilt soon.

The spindle I pulled apart had a Torrington Y-160 (I think, the last digit is tough to make out) needle roller bearing and a Hoover (Japan) ball bearing Z9504B. It appears there was another drive in seal, but it was so bad I can't make anything out.

A little help woud be appreciated, I'm sure someone else has rebuilt theirs.

Here are the spindles I rebuilt on my 1974 MF-12 deck. I have drilled and tapped the spindles (1/4"-28) for some grease fittings as well. I decided to place them on the top side of the deck. Granted, the cover must come off to grease, but it will give me a reason to clean the grass out. Make sure you remove the inner shield from the wide bearing so the grease can get into it. You can also buy new clips at any hardware store. I replaced them all when I re-built them. The spindles housings were also sandblasted and powder-coated in matte black while I was in there. All the hardware was replaced with new stainless steel where ever a nut or bolt was to be found on the deck. Yes, even the one that holds the blade on!

I ordered the bearings from Accurate Bearing on-line for the best prices I could find after searching. (800) 323-3116 (ask for Lynne)

NICE 7488-8 (3.75 each) Upper bearings

Torringington B-1616 (4.90 each) 1" wide lower bearings - these are 50% wider than the stock for more shaft to bearing contact. Plenty of room to install these in the housing.

Seal
Trans-Com 10122TC (2.00 each)



Here are some photos of the rebuild.

I just took my old bearings, what was left of them, to a local machine shop and they matched them up......

Thanks FirefyterEmt. I have a couple mf610 decks I want to rebuild. That info will help a lot. Very nice work on the deck!

Todd, that is what is really nice about the bed liner. This fall or in the spring, I can very easily re-paint the deck. The liner allows me to simply mask off everything like the spindles and belt work. Granted, I suppose you could do that anyway under the deck cover, but my deck will still be perfect under the shield and not NEED painting. So far so good, I have mowed four or five times now and it still looks good. Due to the design, the mounting arms hit the top of the deck shield and chipped the paint, and my left tire rubbed the arms at the latch plate before I adjusted the bump stops to clear. All minor things that would happen anyway, the big thing is that it's mechanically rebuilt as well as being pretty!

Maybe next year I can swing it and buy new blades and belts! My wife has been giving me "That look".... But if I only did the expensive mechanical part, I bet it would be just fine... Paint it all glossy red and it's "too much". LOL

You did a great job restoring that deck and it is a great idea about the bedliner. I would have a hard time mowing after redoing a deck that pretty.

LOL, thanks guys! The funny thing is that with the bed liner done like that, I can easily repaint the deck without even pulling off the belts. I can just mask off the outer edges of the deck and if needed, paint the top cover. It needs to be re-painted every year or two to fix the scratches. I tend to scrape it on those t-posts for my garden fence. One day, that will not be a problem when I fiinish my "final fencing" it will be a non-issue.

Wow!! Thanks for this post. Better than new. I like the fact that you improved the deck by using stronger bearings and the bed liner. It gives me some ideas for my MF8 deck when I rebuild.
