Warn Hub Service Manuals WA-1, WL-2 and WO-1

UPDATE: I found this 18-page Warn Selective Drive Hub Service and Repair Manual on eBay last week. This appears to be an earlier version (February of 1955?) than the PDF version linked to at the very bottom of this post (which covers WL-2 and WO-1 hubs).  It covers the WA-1 Automatic Hub and the WL-2 hub. This is document No. WD-255.

Free-Lock Hubs on eBay

UPDATE: These Free-Lock hubs are still available.

(11/18/2020) This ebay ad for Free-Lock hubs provides the most detailed pics I have for this version of the hub. These are 27 spline, which means they were produced after 1972? If that’s the case, then for some reason the Free-Lock brand that was abandoned circa 1959 was resurected for these hubs.

Imperfect .. Perfect Circle Branded 10-Spline Selectro Hubs on eBay

• CATEGORIES: Parts • TAGS: .

These are imperfect Perfect Circle hubs as a cam is broken (see broken part in pic one). However, there are some useful photos of these Perfect Circle-branded 10-Spline Selectro Hubs.

View all the information on ebay

“Selling the used locking hubs in the pictures. These are aftermarket and called Perfect Circle. We don’t know much about these hubs. My husband said he removed these from a 1971 Jeep truck that was in a junkyard. He thought they were neat and brought them home. Of course they are the special 10 spline hubs. These appear to be complete, but the “cam” piece (#8 in the schematic) seems to be broken on at least one hub. Look closely at the pictures and determine if they are something you want. Maybe just a little eye candy for the bench area. These are being sold for parts or not working. Hopefully there are enough good parts here to allow someone to complete their project. These are very clean and ready for a new owner.”

As you can see, the Dualmatic schematic is similar to the Perfect Circle Schematic, though, surprisingly, the casting of the base is slightly different. I’m betting the cams are the same though.

Unusual Dualmatic Hubs (Possibly for a Ford?)

• CATEGORIES: Features • TAGS: .

Tim’s father-in-law purchased these Dualmatic hubs, but Tim’s unsure what vehicle they fit. Given the hub model number is F-230, we believe these were likely used on a Ford truck (possible the F-250, as that was the model of truck his father-in-law had). Anyone recognize them or know if they’d fit on a 1960s/70s Ford truck? The hubs are 19 spline.

Dualmatic Twin-Lever Hub Variations

• CATEGORIES: Advertising & Brochures, Features • TAGS: .
dualmatic-hub-sticker

You’ll note that the patent number 2854111 is the same one connected to this single lever design: https://patents.google.com/patent/US2854111. Read to the end, as this patent number appears connected with an odd looking, Dualmatic-related hub.

This post is all Scott Gilbert’s fault. We got talking about the different color of Dualmatic hub labels on Sunday and, suddenly, my Sunday afternoon vanished into research!

This post leverages the great work from the CJ-2A.com’s dualmatic twin-lever page and the ih8mud hub forum about Dualmatic twin-lever hub variations. For the record, I’ve never owned any of these hubs, so I’m leveraging pics and the internet as best I can. It is a working post. If you have corrections or comments, please let me know!

If only I had each set of hub in front of me I might have a better shot at highlighting the differences (height and faces), but I do not have them. So, I’ll just do my best with the faces and some documentation for dating purposes.

I was going to use the CJ-2A page’s nomenclature, but after studying the different faces, I think it’s better, as I hope you will see, to expand the styles types:

Design A: Recessed center, full ribs, sharp-ended ribs
Design B: Raised center, full-ribs, sharp-ended ribs
Design C: Raised center, full-ribs, round-ended ribs
Design D: Raised center, one-end of both ribs recessed from the edge, all round-ended ribs
Design E: Raised center, both-ends of ribs recessed from the edge, all round-ended ribs
Design W: These were marketed by and stamped as Watson hubs (hence why I call them Watson hubs), but also stamped and sold by third-parties like Sears unstamped and unbranded.

Before we begin with the twin-lever design, let’s look at the single lever design. Dualmatic’s founder Charles Simonsen’s original patent was for a single lever design.

dualmatic-single-lever-charles-simonsen-patent1-lores dualmatic-single-lever-charles-simonsen-patent2-lores

This photo may highlight why that design didn’t hold up well and why support was needed for the cam levers:

dualmatic-first-hub-single-lever-g503-2

This photo was found on a G503 forum. You can see that the lever has been highly stressed.

CONJECTURE: If the bending of the single lever was even a somewhat common occurrence, then it would explain the shift to a dual lever, rib-supported design. One of those early designs may have been the Design W or the Watson hub seen at the bottom of the post, but it seems to me that when full of mud and small debris, that loosening the levers would have been difficult. So, my theory is that the next idea was Design A, which is the earliest one documented with a specific date.

DESIGN A: The earliest example of a Dualmatic hub with a date comes in the form of this April 1958 advertisement in Popular Mechanics. For our purposes, this would be Design A. It has full, un-rounded ribs and a recessed interior

design-a-recessed-dualmatic-hubs

Design A hub with recessed center, full ribs, sharp rib ends.

design-a-recessed-block-dualmatic-hub-brochure

Design A hub with recessed center, full ribs, sharp rib ends.

Design A can also be seen in this undated brochure, most likely pre-1963 given the lack of full-size jeeps:

Curiously, Design A was still around in 1964, as evidenced by this 1964 Montgomery Wards catalog ad below, but a new type of style appeared, which I call Design C, with a raised center (for branding I assume) and full, but rounded-ribs (and around as late as August 1965 in a Four Wheeler Ad):

Designs A & C Dualmatic hubs. Lower pic — Design A hub with recessed center, full ribs, sharp rib ends. Design C Dualmatic hubs with raised center, full ribs, round-ended ribs.

DESIGN C: Here is a better pic of Design C. You’ll note that the sticker branding is colored black. So far, the consensus is that there were three different colors of stickers, black, blue and red. Again, when each was used and why they changed is uncertain:

design-c-raised-center-hubs-dualmatic

Design C Dualmatic hubs with raised center, full ribs, rounded-ended ribs.

DESIGN B: At some juncture, Design B was introduced. Design B had a raised center and full, sharp ribs like Design A. You’ll also note that this has the red center branding sticker: Continue reading

Unknown Hubs … Anyone Recognize Them?

• CATEGORIES: Features • TAGS: .

I am looking for more information on these hubs. Anyone recognize them?

Austin Smith posted this unusual hub to G503 Facebook. He theorizes they may be a freewheeling hub of some kind, as he can find no way to spin the hubs nor, after disassembling it, did he find any internals to do so.

A Hubber: Easy Engage’s Device For Hub Management

• CATEGORIES: Features • TAGS: .

UPDATE: Marty notes that this is called a “hubber”, a correction from “scubber”.

Barney from Barney’s Jeep Parts shared an image of this Easy Engage device. It’s called a “hubber” (no R) and it’s made of a durable plastic. It’s used to engage certain types of Warn hubs.

He added: “They were a dealership counter accessory on a cardboard display, but were not Kaiser or AMC Jeep. It works perfect if the hubs are properly lubricated or not in a “parking” bind. And, it won’t mar the metal as homemade ones can.”

hoffman-hub

In December of 1958, Floyd G. Huffman filed a patent for a new type of hub structure. His patent, designed to “provide a hub structure that can be simply and quickly manually operated to release the front wheels so that they will rotate freely on the axles without the necessity of having the gears etc. rotate simultaneously when the front wheel drive has been disengaged” was finally approved in April of 1961.

John’s Cutlas Selective Hub Rebuild

• CATEGORIES: Builds, Features, How To • TAGS: .

John recently rebuilt a set of Cutlas Selective Hubs, the type with the knob that rotates to engage and disengage the hub. There appear to be at least two styles of these hubs, one with a flat top and one with a groove, so that a tool (or improvised tool) can be used to help engage, disengage the hub.

This exploded overview from 1961 shows how the parts assemble (see the full brochure below this post):

1961-12-01-cutlas-selective-drive-model100-2-partial-lores

As you can kind of see from this diagram, there are two sections: 1) is the hub cap that holds the knob and the spring in place (from part 107-2 in the middle and everything to the right of it) and 2) the hub base (part 108-2 and everything to the left of it).

John wrote, “Overall I’d say these are my favorite hubs I’ve worked on so far. I have a pair of Warn hubs (with the tiny needle bearings) and a pair of Selectro hubs (big chrome knob type). The Warns seemed like a real pain to rebuild since the needle bearing were in rough shape. And the Selectro hubs, while very easy to operate, were probably the weakest design I’ve seen.”

Here’s a look at John’s finished product, as it’s the best example a complete hub next to a hub with the top separated from the base:

cutlas-hub-groove-rebuild-john8-lores

I went with a 2 tone paint job just for fun. If it doesn’t last for any reason I’ll end up with the whole thing gloss black and a chrome knob. The body was so badly pitted there was no saving the original finish

HUB CAP:

We’ll start with the hub’s cap first. John provided the following note: “To remove the coupling piece (part 102-2 Coupling) from the chrome cap (with the cutlas knob) you have to line it up right with the correct groove, then push down firmly against the spring inside (part 110-2 coupling spring). While pushing down spin the coupling, and then the coupling spring will pop the coupling right out and its free.”

With the inner portion of the cap apart, you can see the coupling ring, the coupling, the coupling cam spring (part 107-2) and the coupling cam pins (parts 105-2).

1958 & 1960 Cutlas Power-Lock Brochures

• CATEGORIES: Advertising & Brochures, Features • TAGS: .

UPDATE: The bottom brochure examples show a brochure from 1958, probably Cutlas’ first one. You’ll note that the brochure (and the hub itself) was branded “Power-Lock”. However, the 1960 brochure (shown just below this text) lacks any “Power-Lock”branding. Perhaps someone else knows why, but I can find no reason why. Maybe there was some concern about whether the patent would be awarded? (It wasn’t awarded until 1962).
