857 Starter Gen

[Sparky-(Admin) 23,909]

  The starter/generator on my 857 starts and charges well…but it’s noisy. It’s model #1101973.  I’m looking for a rebuild kit. Amazon has what I think is the exact same kit that I Save Tractors was selling (some picture and same write up) for $43. 
  The number on mine isn’t on the list that the Amazon ad shows, it lists off many numbers and then says “and many more”. Am I one of the many more? I assume mine is just a standard start/gen from the 60’s? 
  The last two pics are off the Amazon page.

If you take the s/g apart and find that the brushes are in decent condition you might be able to find just the bearings for it.

Mike:

That kit fits both styles of S/G's. Early ones with 2 ball bearings, later ones with 1 bushing and 1 ball bearing. Should be fine? Does Yours have two oil cups on it?? My 854 does - 2 bearings.

Check on Fleabay  - search under Delco Remy Starter Generator. There is an Electric Shop that sells kits... good feedback rating.

Haven’t opened it yet, I suspect it’s all original so I figure if it’s apart I might as well replace everything and hopefully never have to open it up again.

Didn't we just do this?

 We did…what I wanted to know is if the Amazon kit I showed is correct as I didn’t see my start/gen number listed.

 Bill, no oil cups on either my 857 or my 867. I can see when the casting has been changed to eliminate em though

They just become a conversation piece when you use sealed bearings....

The Genny's are pretty much all the same. Use the same bearings or maybe one end has the bushing. 90% of Delco genny use the same R430 brushes. I've probably done about a dozen WH genny's and everyone was the same.

On the one that I’ve done, the pulley-end bearing needed replacing, but the other one was tight, smooth, and quiet so I left it. The brushes were only ⅓ gone so they got left in too.

Pulley end bearing - a classic case of overhung load. Constant sideload from the V belt - even when the tractor is off.... The inner bearing / bushing just cruises along for the ride!

When I first set up the 854, I tried not to over tighten the S/G belt. Then I watched it slip on the first crank as it hit the compression stroke (this is a spark-retard K181, so no help on compression). So much for being “gentle."

If you have bearings on both ends this is a kit I have used with good results.

         A raw edge cogged belt is best for a S/G.
