Technical Help identifying rear end & transmission

Greetings All

Because I didn’t build my car, I need help putting the puzzle together please.

Hopefully the photos will help.

Thanks!

 

Cant help on the ident, of 47/11 is indicative of gear ratio, its pretty steep.

 

looks like a rear from an early to mid 50s ford, either wagon/delivery/pickup, and a mid 60s transmission. The rear is a Spicer 41, and the trans is a Ford top loader 3 speed with the 1965 and later design case.

Pictures that show a bit more of everything, instead of just the details, will help.

 

My concern is that I run out of 1st. gear very quickly. It seems to be geared pretty low for the weight of the car. I don’t know if it’s the transmission or the rear end or possibly both that are geared low.

Here’s a full on shot of the rear. I can’t get a better one of the trans.

 

Looks like That's out of an old Jaguar and looks like it has 4.27 gears. 4HA model designation more specifically. Very similar to an old Dana 44 but with bolt on hubs at the wheels.

 

The transmission is 1:1 in high gear, but the rear end gears are very steep, as he said.

 

4.27! Well that sure would ‘splain why I run out of 1st. gear so soon. Even in 2nd. and 3rd. It seems too low.

Any remedy suggestions would be greatly appreciated.

Thanks

 

Either install an overdrive transmission, or change the ring and pinion in this one.

Cryoman, I have no doubt that you speak truth, but I don’t understand why a Jag rear end would have U.S. patent numbers on it. Would you mind schooling me?

Thanks
Jeff

 

Sourced from Spicer Dana perhaps?

I followed the link you provided. If my conversion calculations are close, that gear set is about 750.00 before shipping. Is there a “Walmart” equivalent that you know of or is that price good?

 

Or go to taller tires!

A cursory search appears that maybe Dana 44 gears will work. Look further or contact a vendor like Randy's Ring and Pinion and see if that is the case.

 

Car manufacturers share capacity all the time. Not uncommon for Dana/Spicer to build things for other companies and fit whatever tubes/axle ends required for the build.

 

Try this thread, might just have the info youre looking for

Again, what wheel bolt pattern does it have? I don't know what the rear is actually from, there were several vehicles that used the Spicer 41 rear. I had a 59 Chevy pickup that came with one, six lug. Ford cars used them with 4.5" bolt circle, Ford trucks with 5.5", I think Jags used 4.75" bolt circle, and someone mentioned something about different hubs.

More info needed!

 

These rear ends, in Jaguars, came with a bolt on hub at the wheel. These were commonly found in Jaguar XK's.

 

Here you can see the bolt on hub.

 

Just finished dinner and now I’ll digest all the info sent my way!

Here’s a photo of the rear brake assembly if that helps. The bolt pattern is 5 X 5 1/2

 

Interesting. Looks like those are one piece axles. Hmmmm

 

Its entirely possible, given the one piece axles that its a Dana 41 out of an old jeep. Hard to say for sure but its definitely a Dana 41 center section. Out of what exactly? Who knows. The ratio tag looks identical to the Jaguar units I've seen in the past that's what led me to the Jaguar connection but the one piece axles points more to a jeep axle especially with the 5X5-1/2 pattern. Hope that helps.

 

Looks like 5.5" truck bolt pattern, eh? I'd see if I could find info on the Ford F1 rear from the early to mid 50s, see if it matches what you have.

When did jeep go to one piece axles? they had separate hubs for a while, didn't they?

edit: 48-50 F1? https://www.jalopyjournal.com/forum/threads/1948-1950-ford-f1-dana-41-complete-rear-axle.1076338/

 

Try searching part and patent numbers.

Quote: BTW the Salisbury 2HA seems to be equivalent to the Dana 41, used in 46-50 Jeep CJ2&3s and 48-56 Ford F100s so there is still some parts support.

 

Jaguars did use a lot of American parts. For years they used a spicer 44 rear ( just like a old old Dana 44 ) Jim you are right they did have 4 3/4 bolt circle.maybe it’s an old Dana 44 out of a ford truck? Dana 44 has been around since about ww2

 

it says 41 right on it, it's not a 44. The cover is a different shape, also.

 

I can't tell if the last number is 6 or 8, but there are some 6s:

Better, maybe:

The 7006 number just means that it's a transmission case. The C5AP thing means it's for a 1965 full size car. (although other applications could use the part, and it could have been used for several years).

 

Okay. OP should look for a tailshaft housing p/n and transmission tag, then look at toploader info, which would likely narrow it down.

 

Whew! So much information. I thought for sure I would get responses like, “oh, that’s easy, you’ve got X,Y,Z. Wishful thinking on my part.

I’m going to put it up on stands tomorrow and try to find some more info, tags, etc.

It starts up front with a great running Y block so I’m hoping that it’s Ford all of the way back. We’ll see.

Thanks everyone
Be well
Jeff
