NP242 H&T Yoke Confirmation

Hylander · Nov 25, 2009

I'm ready to do the SYE on my NP242
Is this the correct Yoke ?
3103-27CV, Is there a better place to order it from, or a better one to order ?

Other than the Yoke and Grade 8 3/8" bolt & washer, anything else I need ?
Also since the Yoke is actually a Slip Yoke, what keeps it from sliding on the output shaft.
The bolt keeps it from sliding off the shaft but what keeps it from sliding forward ?

Do you have a write up that you are referencing on this? You simply can't swap yokes and make it a SYE, which I assume you know already. Being a hack and tap you will cut your our put shaft, tap and drill it (where the hack and tap in H&T comes from), maybe change the rear housing and put a bolt thought the yoke to hold it to your output shaft.

The bolt tightens it down on to your shortened output shaft so it can't slid at all.

Yes I have read all the write ups, but they don't seem to really address how the Yoke rest on the output shaft.

Heres a thread I found when I was doing mine.

I ended up using a Powertrain Industries p/n 3103-27CV yoke. Cut, drilled and tapped a 3/8" x 16 hole in the out put shaft. Welded a thick washer in the yoke and bolted it up. Been running it that way for 4 years +. No issues. I also running a front drive shaft on the rear, this works out well since I only need to carry one spare drive shaft. Hope the thread helps.

Why the welding of the Washer ?

I'd probably throw a few tacks in just to keep it from migrating, but a 1/2" grade 8 washer fits PERFECTLY in the end of the yoke so I think just loctite on the bolt threads should be fine. I guess you could put a 3/8 washer on top of the 1/2 washer and then use a 3/8 bolt but I'm extremely tempted to just use a 1/2 bolt. It will make drilling and tapping more difficult however.

If the washer gets any kind of play at all (stretching anywhere) it will start to skip and warble, which will cause the bolt to work itself out. Better to tack it and be safe, even if you are 100% sure that it will never come loose
