Lever ID wanted

[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.

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.

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.

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.
