How Much Wobble in Woods Belly Mower Drive Sheave

Postby kajun » Thu Jul 06, 2017 11:59 am

Men:

Pls forgive me for asking before I fully investigate/disassemble . But how much wobble is permitted in normal operations in the drive sheave [ Woods PN 1481 ] of a Woods 42C-4 belly mount mower ? With belt off on mine , I get a 5 degree wobble from horizontal .

What is the fix ?

Obliged for guidance.

So you are talking about the main central pulley, item 18, in the Figure? (This figure may not be an exact match for your mower, but it apparently uses the same part number you found.)

5 degrees sounds like a lot to me. Sloppy spindle bearings. I would be shopping around for a new spindle, item 25, part number 305. Maybe the bearings that go into the spindle can be had separately, maybe only as an entire spindle assembly.
The site where I found that figure also has a breakdown of the spindle assembly, though it didn't seem to match the spindle shown in the main figure. :roll:
If you've got a Woods distributor/dealer that you are working with, you can work out the cost difference versus labor difference for the spindle assembly versus the individual bearings.

Tim:
Much obliged . Yes , your Figure , part 18 , matches to my drive sheave.
However the slop is not at the drive shaft [ central shaft of spindle ] ; there is no movement there . The slop is between the drive sheave in way of where it meets drive shaft . So far as I remember , the drive sheave secures to the drive shaft with keys . Perhaps they are worn .
Is it true that if properly fitted there will be no slop [ horizontal movement ] of drive sheave at all ?
Truly appreciate the help.

Ok, here is the correct diagram for a 42C-4.

And the spindle diagram.

Yes, there is a key.

So the spindle bearings are good, but the pulley is loose on the spindle shaft?
Check for:
Loose/incorrect fasteners holding pulley on shaft -> Tighten/correct fasteners
Worn key -> Replace key
Worn pulley -> Replace pulley
Worn shaft -> Replace spindle shaft or assembly

If left to wobble, the pulley and shaft can eat each other up over time.
It should be pretty obvious once you get down there and start pulling it apart.

Incidentally, I got those diagrams from an online search that took me to: https://store.germanbliss.com/woods-42c-4-ih-farmall-cub-undermount-mid-mount-rotary-cutter-parts

We probably have the manual for that mower right here on the site, though.

Good luck!

Tim:

There was no-pulling apart on Saturday , July 8 . I had to soak with PB Blaster for full week before I could get hex drive off .When I finally disassembled on Saturday , July 15 I found some wear [ not too substantial ] of bronze bushing . I replaced bushing and reassembled overrunning clutch and I'm good to go .

Deeply appreciate your help.
