I am looking for any references of the parking brake drum being used as a belt pulley. Has anyone ever seen anything ever driven from the e brake drum? It really looks like the grooves in the outer drum would hold a v-belt.

The only belt pulley's I've ever seen used on jeeps have been PTO driven rear mounted right angle pulleys very similar to those used on Ford and Ferguson/MF farm tractors; (I don't recall ever seeing or reading any jeep literature that stated the grooves on the parking brake drum were designed or engineered to drive belts, but then again, I didn't read every piece of literature ever printed by the mfg. either).

Yeah I have not heard of it used that way either.

Naturally it would probably have to be used while stationary with the rear wheels jacked up.

Just looks like one could rig a small generator or something in the bed and drive it off the drum.

K~B () - 22 Mar, 11:53 AM

The Spicer 18-H PTO drove a multiple "V" belt drum.
The belts came up through a hole in the floor pan near the 18-H PTO unit to drive the welding generator.
The Jeep Operation Data Booklet shows a picture of the G.E. welder mounted in the bed of an early CJ.
This booklet was produced sometime in the era of the CJ-3A.
So the welder generator shown would be 1949 to 1952.
Also as I indicated earlier the Hobart welding generator was later on mentioned in the OM 1010 circa about 1964.
The Hobart welder was given status as Jeep Approved Special Equipment.

Wow that thought was going though my mind as I was reading this.. Ive seen welders in old jeeps & they sit real close to where the brake brum is located... But you'd have to have some good wheel chucks with you ,,, I might drive a Dump truck to make ends meet butt at heart Im still a rod burner,,, & Hobart was a real good weleder...

Do a search on this they will not let me copy anything ,,,

This is good stuff. It would be great to find a few pictures someplace of it set up.

Thanks for posting the data operations booklet Dave as some of the pictures sure bring back some old memories. Though I've seen a number of old jeeps with the mounted three point lifts, the picture/drawing of the double bottom disc plow reminds me of a couple of jeeps that used to sit outside the US Forestry Service building in Groveton, TX. These were used to plow deep furrows through the trees in the East Texas piney woods to prevent the spread of fire. The jeeps were later replaced with more powerful JD dozers that were kept on the dove tailed flat beds of 2 1/2 ton Chevy and Ford trucks. Thinking back now, I seem to recall the jeeps may have been 3B's.

Here you go, not a 3b but some fun

Coined by Popular Mechanic’s Found here:
(The link is larger than the Jeep)(Just Google: The Mobile Midget Plane starter)

http://books.google.com/books?id=29kDAAAAM...tarters&f=false

The Mobile Midget Plane starter was on a cut down Cj3a. The interlock pin was removed and the front axle was locked in at all times. The drive for the generator came off the rear break drum.
To see them in action here is a really fun link to a movie clip from. “The Bridges at Toko-Ri”

http://www.youtube.com/watch?v=tp4AmbYTnRQ

Here’s a link to a really good picture and I have translated the text.
http://willysargentina.com.ar:8090/viewtop...ab5f4628a4f3155

(Translation)
Jeeps really are not, but APUs (Auxiliary Power Unit) used to start the engine and electrical power aircraft on deck.
Made by O.E. Szekely Co. of Philadelphia, components and parts used Jeeps M38/CJ3A, engine, chassis and body of the front axle (mounted securely, without suspension or direction, etc.).
The direction is effected from a small rear wheel (actually two closely spaced) which mounted on a vertical pivot maneuverability provided an astonishing, as seen in the video.
A generator coupled to the PTO provided the current requirements for aircraft systems

This link has a good photo showing anti roll skids under the Jeep.

When I first came to the page looking for a 3b there was a M606 in the southern desert of California. Sitting alongside were 3 of these units, all for went for $3000,00 off Ebay. Living 2800 miles away I could only drool.
I would have given a unit to the Yankee Air Museum because here is what’s left of their Jeep from a fire that nearly wiped out a B-17 and their whole collection of planes.

If anyone of these units let me Know.
