880 Power Booster

[Antique Acres]

Good Afternoon all. This is my first post on the forums. My father (Germantown Green on this forum) are getting ready to reassemble our 880 power booster. I have read through the shop manual and have since discovered that there were many changes throughout production of the power boosters. This power booster is on a 1958 880.

The bearing that has the shield in my pictures is the bearing that came out of the power booster. I have located another older stock bearing that does not have the shield. The replacement bearing I have located does not have the slots milled out of the inner race of the bearing like the old one does. Should I be concerned about this or should I have slots milled in the new bearing and see if I can install a shield in my new bearing.

Thanks,
Bailey

Did you closely check the old bearing for any letters/numbers?

 

[Antique Acres]

Yes scooter, the part number from my old bearing was a
new departure 4L13. This new bearing is the same
number.

OK. Couple of things- what's the Oliver part number and do you have the capability to post a picture of the bearings side by side?

 

[scootergmc]

Also, the Oliver parts book lists the original Torrington bearing numbers for the corresponding tractor serial numbers, assuming your power booster is original.

 

[scootergmc]

Nevermind, I found it. I guess they did source the ND bearing.

Is it a 43L13 and not a 4L13? Oliver part number 102142A?

 

[Antique Acres]

Scooter,

Yes the bearing is Oliver #102142

New departure 43l13

I tried posting pictures of the 2 bearings side by side but
they would not upload on my phone.

My email is enabled in modern version. Send me a photo of the original bearing. 43L13 might've been the original part # "style" of bearing but NDH would've updated their part numbers to correspond with your features. Just to confirm, there's no snap ring on the outer race?

 

[scootergmc]

OK OK, last post of the night, but go on eBay and look up NDH part number Z993L13. Shielded on both sides, correct? I'm thinking that's your bearing?

That should cross to a SKF 6013 series for a more modern selection.

There was a page in the shop manual just for the revisions in the power booster. I can mail you a copy. J.
