Can you verify the measurements in this chart and add specs for the s44?
Thanks

Something to add...

This is not verified, just info I've collected.

The Saginaw 44 (S44) joint is also known as the GM 3RL.
This u-joint uses 'inside' locks.

The 447 is a 1350/S44 adaptor joint, NOT a 1350/1330.

73-87 trucks never came with a 1330, it's an S44.

1330/1350 joint is Neapco PN 2-3050.

1310/1350 joint is Neapco PN 3-3140.

S44/1350 joint is Neapco PN 2-1153.

eh ..... hmm ...... nice ..... whoa ...... *me explode*

 

[ProJunkRacing]

we shure got some great info and tech dudes o this site

 

[pvfjr]

You forgot about 3R...

Can somebody put this in the tech article thread though? I'd hate for it to get lost. Could save an awful lot of posts about U-Joints.

 

[Cricket]

Thanks guys, I needed that. Good post!

 

[thebigdaddyof2]

You forgot about 3R...

Do you mean the GM 3RL?
It's the same joint as the S44.

Anybody know the actual width of the S44?

Anybody know the specs on the 1480?

 

[Zeus33rd]

I don't know the specs on the 1480, but it's the same as a D60 wheel joint. Spicer part# 5-806X.

 

[sandawgk5]

The specs for a 1480 are

Cross width= freakin huge

Cap diameter= really big .

I dont really know anything at all this is good info though.

Well I can tell you that a 3R joint has the width of a 1350 u-joint. The bearing cap is directly between the 1310/1330 and 1350 sizes though. I believe that 1310/1330 are 1 1/16 and the 1350 is 1 3/16, leaving 3R at 1 1/8. 1310 is 3 3/16 wide, and 1330/1350/3R are all 3 5/8 wide. So if S44 is the same as 3R...

 

[u2slow]

1350/1410 cap is 1-3/16" AFAIK.

Good info, Muddog.

I measured the S44 tonite and updated the tables with info.

Really helpful thread. Thanks.

Holy dead thread

This seems like the most helpful place to put this question and possibly someone later on will find it also.

OK, so I was searching, and Googling, and any other-ing I can to find info on the 3R / S44 u-joint. I ground up the strap bolts on my 12b the last time out and I'm wanting to go with a u-bolt style pinion yoke.

As listed above, the 1330 and 1350 have max op angles of 20*. I was wondering if anyone had found what the max op angle of a 3R / S44 is. Does anyone know how to calculate this? Is it as simple as pulling my rear shaft and pushing the yoke around till it will not move any more and measuring the angle?

I think this should about cover any u-joint questions...
