I 'm gonna try this time Hippie...Dana 44 Question

[studebaker-R2-4-me]

I purchased a 3.54:1 ring and pinion to swap out my 3.31:1 TT in my Hawk. I was trying to track down a Master bearing kit c/w shims, pinion seal and the other stuff that comes in a Kit.

My question along with Hippie is that the pinion that I bought is a 10 spline. The kits for pre-1967 Dana differentials are for 19 spline. One kit makes a note that the 19 spline is the same kit as a 10 spline

With that said, and all the other posts lately on the Dana 44's...
did I buy the correct ring and pinion for a 1964 Hawk

I have not taken apart my differential yet and want to swap this ring and pinion out before the Cedar Rapids Drags.

The correct information would be cool for Hippie and me.

Thanks Allen

Are you talking about the splines on the pinion shaft for the Yoke?
If so, the shaft size should be the same . I have done a few 44's and have used the same bearings for all of them.

Get an install kit for a D44 19 spline. The later 30 spline(also 27 spl flange axle) uses different carrier bearing cones.(#25590-30/27spl,#25577-19spl. Everything else you'll need is the same. If you use a later ring & pinion you have to replace the input yoke as the spline changed from 10 to 26 spline. Here's install kit from Randy's ring and pinion, http://www.ringpinion.com/ProductDet...px?ProdID=3462 Master kits are listed on this site.http://www.backcountrybinders.com/axle_&_diff_parts.htm
Rereading your post to avoid confusion the 10 spine is pinion and the 19 spline is the axle. . Then ring and pinion will interchange between the different axles splines. The only difference is spline count on the pinion.

Jamie and Leyrret,

Interesting, I have checked out both of these sites and the costs of these kits prior to my post. I also looked a National Drive Train.

I am talking about the yoke and the one that I purchased is a 10 spline pinion. I am currently running Fairborn flanged axles in my '64 Dana 44 TT which I believe are 19 spline axles.

When Randy's, Back Country Binders or National Drive train mention 19 spline are they talking about the pinion splines or the Axle splines? This is where my confusion comes in. The mechanic that I am having do this has never seen a 10 spline pinion and was surprised to hear that a 10 spline Dana 44 pinion even existed. He's never done a Studebaker either but hundreds of Dana 44's.

Are all '60s-'64 Studebaker pinions 10 spline? I just want to make sure that I have purchased the correct 3.54:1 Pinion and Ring and then get the right parts from Randy's Ring and Pinion or the others the first time.

Most Stude Dana 44's I've seen have a 10 spline pinion...although I have seen a 26 spline in later cars.

I don't think it will matter, however, to the master install kit.

You will need the correct pinion yoke (obviously) depending upon which pinion spline count you end up with. Both are readily available.



Just a couple of words of caution (disregard if you are way ahead of me).

Make sure you have a MATCHED ring and pinion set (same serial numbers scratched in to both). You can't interchange rings and/or pinions from different gear sets.

Unless you have the proper precision measurement tools and experience, it is better to have a rear end shop do the install for you. They will have the bearings, shims, seals, etc. on hand, BTW. No need to buy them in advance.

Dick,

Okay that's good to know that most if not all had 10 Spline pinions! I should be good to go then. My Dana uses Mechanics u-joints so I am hoping all match up with the Yoke that I currently am running in my 3.31:1 differential and the 10 spline pinion that I purchased.

The mechanic that I will be using owned and operated a rear end shop, he subsequently sold that shop and now works for the speed shop that rebuilt my fiasco I had with my R2 engine. The ring and pinion that I want to install, I purchased off of Tom Kurkowitz in Reedsville Pa. are a matched set. I was asked by the mechanic to track down the bearing set for this ring and pinion swap.

Thanks. I have a slight advantage, a good friend owns a transmission shop. I'm rounding up the "old" stuff and getting the common parts through him and he'll go through the rear end for me and set it up. It was pretty cool scoring the NOS 3.73's!

I think I got a pretty good deal on the master bearing kit from National Drivetrain to set up my Differential for anyone that is interested.

Kit comes with Timkin bearings -

Master kits include, Timkin Pinion and Carrier Bearings, Pinion and Carrier Shims, Pinion Nut, Pinion Nut Washer, Pinion Seal, Ring-Gear Bolts, Crush Sleeve (some applications), Cover Gasket, Gear Marking Compound, Locktite, Baffle and Slinger.
