Not listed 1957/72. Studebaker didn't manufacture trucks after 1963.

A 2R10 Studebaker truck is a 170 cid I-6 (flathead) 3/4 ton made 1949/52.

Back in the 1960's, I made up a cross reference list for Studebaker nuts for interchangeable Studebaker & Ford parts.

Y'all know of course that Studebaker used Spicer (Dana) 44 rear axles in 1/2 ton pickups thru 1963 and passenger cars thru 1966.

btw: I wonder how many ex-Studebaker partsguys are typin' away on that Studebaker site?

There's one here on FTE that once in a while types Studebaker part numbers, mainly for Bill Walford, who has an Avanti.

Many moons ago...before I was a Ford partsman...I was a Studebaker/Packard partsman.

 

Glad to see you back, Bill. Hope you're feeling better. Just take it easy. Stu

 

what happened to all the scrap rear ends everyone had?

 

Ive got one you can have, stop by tonight after work and I'll help you load it! Seriously

 

Does anyone have a set of 4.11s? I have a friend that is looking for a set.

 

Me too! It's just sitting behind my garage collecting rust...

 

Assuming you've looked through this whole thread, I asked a while back if anybody had ever actually heard of or seen a stock 4.11 gear set. I got no responses. The only ones I've heard of were from Studebaker guys. One was in a 1950 F-2, and the other a NOS set from the now defunct Studebaker parts supplier SASCO.

I got my sets, which are new racing sets that are now being reproduced, from Chuck Mantiglia at Chuck's Trucks. He'll know more about availability and cost. Here's his link. Stu

Im still looking but none yet!

 

Studebaker truck part numbers:

682046 .. 4.11-1 R&P / 1948/52 Stude 3/4 ton.

1685531 .. 4.10-1 R&P / 1953/61 Stude 3/4 ton.
------------------------------------------------
Studebaker International, located in Greenfield IN has the largest stock of NOS & repro parts.

Myer's Studebaker Parts located in Duncan Falls OH has a large stock of parts. Myer is a former Ford line mechanic.

Studebaker's West, located in Redwood City CA is another large parts supplier. Has reproduced the 6V overdrive relay that is the same as Ford used.

There are dozens upon dozens of Studebaker NOS parts suppliers, because...

Studebaker made enough parts for TEN times the number of vehicles they actually sold (I kid you not), so there is a HUGE supply of NOS parts still available.

EDIT: I just spoke with Chuck Collins, owner of StudebakerParts.com: He said to try BLUMENTHAL TRUCK in OK for R&P's for F2/F3's: 800-262-9557.

When Studebaker folded the tent in March 1966, the parts division became SASCO = Studebaker Automobile Sales Corp.

O1Y4209A .. 4.11-1 R&P Kit (Timken Part Number: A34552) / Obsolete / 1948/52 F2, F3.

AB4209D .. 4.09-1 R&P Kit / Obsolete / 1953/56 F100.

 

That's great info, Bill, both the Timken and Stude' part numbers. As few of these as seem to be known about you'd have to think that there is a treasure trove of them sitting somewhere. I'd seen the Ford number in the Chassis Manual. Any idea why none of the product literature or Dealer Handbooks of the era ever listed the 4.11 as an option? The only place I'd seen it was in the Chassis Manual. Stu

 

Cannot answer that question, but it doesn't make much sense when you consider that the O1Y R&P part number actually dates to 1940.

Did you notice what I edited in?

I wouldn't be bit surprised if there were stashes of these R&P's laying around in dealers basements/attics/storage rooms.

There may even be a few in junkyards...cuz many junkyard owners used to go to the auctions when dealers folded the tent.

There's one locally that has all sorts of NOS parts...the same place I referenced that has the wheels.

Since 1967, I've prolly spent 6 figures buying these parts (and made at least 4 times that amount when I sold them).

There is next to no NOS car parts left, but NOS truck parts can be found...if one searches around a bit.

I took FTE member Gangstakr there recently. He crawled up in the attic...found...and bought a NOS 1960 F100/600 upper chrome grille.

 

Yes I did. When I first asked the question I was hoping to get responses from other F-2/F-3 owners that have these gear sets in their trucks. I'd never heard of any, except for the responses from the Studebaker guys. Since they were available, you'd think there'd be a few still on the road.

What you've said about the number dating back to 1940 might confirm a hunch I've had on them. I've known that the 4.11 was an option on the '47 and earlier tonners, and have assumed that that era truck used the same Timken 51524 axle. But with the oddball 5 x 6 7/8" pattern half shafts and hubs. That's been an assumption because I don't have the earlier Chassis Manual. I've reasoned that the availablility of that ratio may have just been an unadvertized carry over option when the Bonus Builts were introduced. If I remember correctly, you've cited other examples of special order parts that weren't in the standard sales literature. Stu

 

meet a fellow in Findley, OH after El Dora race and gave $100 for complete F-2 rear end, still need one more

 

Boy they are sure out there if you believe all we read about guys swapping in D-60s. And more yet trying to turn their F-2s/3s into half tons by mounting 9" axles. Here's a real good discussion we had on these axles recently. Stu

https://www.ford-trucks.com/forums/9...io-timken.html

Edit - Not sure if this has been said before in this context, but be aware that the cases on the earlier Timkens (pre mid-year '51 I believe) are slightly narrower than the late '51/'52 cases. Only reason I see was they changed brake hardware mid-year '51 when they went from the 14" drums to 12" Bendix. We learned this when Chuck was redoing my rear axle. Stu

 

The story on 4.11 ratio Timken axles in Fords is this: in 1938 Ford started offering the 1 ton trucks. These had torque tube closed drive line Timken axles available in 4.11 and 4.86 ratio. In 1939 Ford brought out the 3/4 ton but used a car based axle, still closed drive. In 1940 Ford changed the 3/4 and 1 ton trucks to open drive and revised the pinion gear to accept a u-joint coupler. If you look at the ring and pinion part numbers, the ring gear part number dates to 1938 but the pinion part number dates to 1940.

I have seen two 4.11 ratio Timken axles in trucks, one in a '38 1 ton and the other in a '41 3/4 ton. I think the 4.11 ratio was much more prevalent pre-WW2. This probably is because Ford was trying to maximize the pulling power of their trucks while high speed use was not much of a concern.
