Roll Pins

[Footer]

Somewhere in the past I remember reading about the orientation of the rolled pins that hold the half shaft to the out put shaft of the transaxle. My recollection is if the pins are oriented incorrectly, they will tend to shear from the action of the suspension.  I did some searches for the topic but have not been able to locate the discussion.

So, if you were looking at the end of the pin installed. would the " outside end of the roll" be in line with the half shaft or perpendicular to it.  Stated differently, would the end be at 3 o'clock or noon?

Thanks.

There has been discussion of roll pin clocking. But roll pin shearing comes from not shimming the ends correctly.

I think it should be in line with load as it is one thickness thicker …

The hole through the u-joint and output is offset slightly so it only fits in one way.

You can put a 5mm twist drill through the holes to hold the shafts together while you press the roll pin through from the other side.

I line up the shafts by eye to make sure they are not 180' out of alignment.

7mm normally.

7mm normally.

for the S2, it's a 7mm with a 4mm insert.  Usually the larger one has the slit to the outside, and the 4mm is inserted 180 degrees (slit to inside).  The inner yoke should be an RCH to the outside so that driving the pin in, it pulls the yoke solidly against the shims. That's how it's always worked for me; and I never had a loose yoke shear the pins.  Thinking the TC is just the same in terms of fittment; please correct me if I'm wrong!

The TC uses "spirol" pins which are one piece coiled (spring steel, I assume) pins for both the 352 and 365 as opposed to the two-piece roll pin setup you describe which is for the 33 box. The 336 pins are 7mm while the TC is 5mm. All that according to r.d.

So I think the conclusion is that it doesn't matter, as long as the pin goes in completely.  My recollection must have applied to a different application.

Thanks.
