Lever ID wanted

[Hanno Spoelstra]

Who can ID the lever on the left (the closest to the camera)?

Pic shows it in and under the cab of a C15A.

aftermarket PTO

[Grant Hopkins]

Probably turning a front mount pto winch or maybe a bumper mount water pump on a tanker.

It can't be powering anything forward because the bell housing and engine mount are in the way. I couldn't find any outlets on the housing making it a complete mystery to me.

Could this PTO be part of the Wireless Truck configuration?

I am asking as the truck has the tell-tale aperture for the speaker tube as found in the back of the cab on a Wireless truck.

[Grant Bowker]

Some comment on the PTO and roof configuration at http://www.mapleleafup.net/forums/sh...661#post215661 post #18.

[David Dunlop]

Hanno, I could be wrong, but the speaker tube for the WIRE-5 was much more square than the one you have shown here and was not as close to the rear window. Also, the dash has the late military instrument configuration, which although correct for 1944 WIRE-5 production, should also probably have the round roof hatch, which is missing completely in any form.

I concur with David's comment regarding the rectangular vs. square opening in the rear of the roof. It does not appear to be original. I also believe this truck should have come with an observation hatch (square or round). If you look closely at one of Hanno's other pictures of the roof it appears that the upper portion has been welded in which would explain the lack of a hatch or hatch opening. It also explains the correct reinforcement ribbing for the roof. My two cents.

[David Dunlop]

Hanno.

Another tell tale WIRE-5 feature to look for is a pair of holes diagonally across the centre line from each other, on the side curve of the upper roof assembly, above the horizontal join, in the left corner. Behind the co-drivers position. This is where the wooden block supporting the signal buzzer would be located. Nice loud buzz in the co-driver's left ear when it went off!

Also note the absence of rife holders or corresponding holes. It appears some sheet metal work has been done. Nice truck however and good to one with a wooden box.

I have looked at the picture in full screen and the only guess I can come up with is an overdrive gear. Is this possible?

[Richard Farrant]

The vertical lever continues down past the pivot pin and believe we are missing something here. The attachment on the gearbox SAE mounting may only be a selector with detent, the actual item being operated not being part of the gearbox.

Is it possible to see anymore photos?

Not for now, these are they only two I snapped on my way back when I realised I had spotted a (to me) unknown lever.

Following my comment in another thread about possible PTO use on the water tank trucks, both the 200 gallon (on 15cwt chassis) and 350 gallon (on 3 ton chassis) had PTO driven pumps in addition to the hand pumps but I don't think the PTO used matches the one being discussed here. The water trucks used a PTO that had the driveshaft leading to the rear and seem to have had both the engagement control and the control leading to a governor to prevent overspeed of the engine driven pump leading forward.
See the attached PDF file for the general layout of the water pump PTO.

[John Mackie]

These aftermarket powertake offs were used on lots of farrm trucks to drive any powered gear. the most common were underbody tipping bodies with the hydraulic punp mounted on the power cylander and driven by a shaft and universal joints.

[Grant Bowker]

Bob Carriere has 2 PTOs mounted on transmissions similar to those used on CMPs (one has the speedometer drive associated with 2 wheel drive on the rear cover). He is sure one came from the remains of a CMP water truck but isn't sure which of the two it is. Neither of these PTOs has the connection to the governor mentioned in the water tank body manual. Depending on the viewing angle, it would be easy for the output shaft to be hidden by the control lever system if the extension to the driven equipment wasn't in place.

[Harry Moon]

The other issue with that PTO is that without a transfer case to put in neutral you can't use it while stationary. For the same reason there is no air pump in that position on a 15 CWT.
I see no levers on the floor for a two speed transfer case. I really don't get that PTO set up and what it could be used for, somebody might have done it and then got to the point of realization that w/o the transfer case it was useless.

I think you will find that the PTO on the side of the gearbox, works when main gearbox is in Neutral. No different to those trucks with tyre pumps and only 2 wheel drive. Going on the assumption that the Chev gearbox is nearly identical to the Bedford (both GM) and tyre pump works in Neutral.

[Harry Moon]

not sure of that.

[hrpearce]

Richard is right the pto will run in neutral, the countershaft is live. I have a pto on a Chev gearbox that came off a Bedford originally.

[Lynn Eades]

Harry, that is the case. The front gear on the cluster is "constant mesh" with the input shaft. To put your PTO into gear you put your foot on the clutch to stop the cluster turning. Other wise it is turning all the time the engine is running.
There are many vehicles with single speed transfer cases that run PTOs. As an example the WC Dodge 4x4 with winch. In fact there are many 2wd trucks without transfer cases that use a power take off to run an auxilliary of some sort.
Some gearboxes will accept 2 ptos and some transfer cases can run a pto.

[Grant Bowker]

To get back to the question of C15A s with PTOs - can anyone think of other C15A variants that might have used PTO other than water tank trucks? Perhaps the question should be expanded to other CMPs (both Ford and Chevrolet since many bodies were built on both chassis) that used transmission (as opposed to transfer case) PTOs?
The C60X is another likely candidate for transmission mounted PTOs since the transfer case position occupied by the PTO on C60S andC60L was used to power one of the rear axles. The C60X is an example of a transmission that could drive a PTO from either side of the transmission (but normally only used the left side opening - perhaps due to interference with the front driveshaft - only a guess)
