Another update on that starter problem with my WD (w/ pic)

For the curious, I took this thing apart today and lo and behold I did have a broken starter spring (bendix spring, yes?) inside.

Parts on order. Hope to clean her up inside in the meantime. She's got 60 years of seeped-in gunk and carbon build-up inside.

I see some scraping on the armature, probably needs
new bearings/bushings too

springs are available. Either from nnalert or steiners I can't remember which.

Last few times I went to get a new spring for my various Farmall's, they handed me an all new drive. The drive had no spring but is like what starters use now. They work just fine and will never break a spring again.

Thing that caught my eye is no center bearing. If the housing is machined for it I would surely put one in. Can make a man out of a boy as they say.

Center bearing?

Some starters have a center bearing between the
bendix and the armature.

Lots of diesals have them and I think most or all
that run oil of some sort in the flywheel housing.

The Allis WC/WD/WD45 series didn't and no good way
to add one either.

Yup , center bearing. IH tractors use very similar starter,(along with a lot of other machines) and some have center bearings and some don't. The smaller tractors like a Farmall C did not use one and I have seen starters on H Farmalls that did not. Some times the drive end housing is machined and holes with tapped threads for the bearing, and some are not. I installed a lot of them over the years and it really helps those 6 volt grunting starters. When you throw the juice to that starter the magnetic fields push and pull that armature toward the pole shoes. If the armature touch's or even gets closer it affects the torque delivered by starter. I have been around a few WC's and know they never had an extra lively starter either so I think a center bearing would be good for that starter. Also, a lot of the commentator end frames do not have replaceable bushings in them and a center bearing will support that armature much better even if that end is worn. Those end frames are expensive to replace if worn and no bushings in them.

Just what engine did use a center bearing if you have seen so many.

Good lord, look at an M farmall starter, 460, 560, 806, 1066 on and on. Only ones that don't are older smaller engines.
