Someone wanna sacrifice a yearling goat and a calf to the picture gods ? They’re very angry again

Top is oem

bottom is generic

SVcummins · Jun 28, 2020

And then the pictures flipped on me ! Bottom Is the John Deere top Napa . This is what the number crossed to

Measurement across the outside of the cups is immaterial.

What matters is the measurement between the inner edges of the snap ring grooves plus the thickness of the snap rings.

But you know that now!

I was thinking more a fresh hit skunk and a bloating raccoon.

NAPA gives you extra room for the retaining rings!!

db,

The state bird of the state of Tennessee is the mockingbird and we have bunches of them. However, as nasty looking as they are, it seems to me that the state bird should be the buzzard. They are all over the place and they do a superb job of cleaning up the road kill. Skunks, raccoons, opossums, armadillos, deer, etc. don't last more than a day or two. The flocks of buzzards descend on them.

Nasty, but good for cleaning up the roadsides.

I ran into a similar situation a while ago.
I considered it a plus as there appears to be more bearing surface.

Had to take the handy dandy cut off wheel and polish a few thousandths off the ears on each yoke in order to get the snap rings on I figured it only takes a very few horsepower to run the thing so hopefully it’ll be ok

SVcummins · Jun 28, 2020

It turned out ok just had to “machine” a hair off the inside of
each ear of the yokes to get the snap rings in

SVcummins · Jun 28, 2020

Well I hope someday comes up with something

SVcummins · Jun 28, 2020

That’s amazing they can do that so fast must be millions of em

The "fix" would have been thinner snap rings.

Some cross kits come with snap rings of several thicknesses.

I keep any extra U-joint rings just for such problems.

I have also held U-joint snap rings against a belt sander using leather gloves to make them thinner.

Less "permanent" damage than grinding on the yoke, IMHO.

SVcummins · Jun 28, 2020

No way to get the snap rings even close to fitting no matter
how thin they are the unjoint is just to wide . Should have got
the one from John Deere was 3$ cheaper anyway but I
wanted to get mowing

CenTex Farmall · Jun 28, 2020

I run into that off and on; u-joint snap rings that barely won't fit, almost right. Sometimes massage the yoke a little and sometimes massage the cups or snap ring a little.

SVcummins · Jun 28, 2020

I’ve found that a quite a few times usually with the cheaper will fit parts from the auto parts store there definitely is a difference between the quality of the u joints you can get . Makes sense they only want to make one part almost right and be able to almost fit A hundred different applications rather than make the part right for each application

SVcummins · Jun 29, 2020

Less the extra width makes the snap ring grooves to wide for
the yoke

.09 can be easily explained by the worn ends of the cross and the insides of the caps.
I learned last summer if the napa u joint says federal-mogul on the box, ask for another. It was pretty sad how poor the tolerances were.

SVcummins · Jun 30, 2020

I shouldn’t have tried to make it fit but I made it fit and it works lesson learned get the right part
