Chevrolet 1533X2 30-cwt trucks

Power Tire Pump

The conclusions drawn above regarding the Power Tire Pump may be incorrect.

We know that the cabs were different between 1533X2 and 1543X2, but these two different MCP cabs were more similar to each other than they were to a CMP cab.

The description in Driver’s Handbook CC60L-HB1 includes “...is controlled by a lever located on the running board valance to the rear of the front mudguard...the dust cap located to the rear of the control lever...disengage the clutch and pull out on the lever” (see first two images for complete text).

The comparable description in Driver’s Handbook C60L-HB1 (a normal CMP) includes “... is controlled from within the cab...the dust cap from the hose connection at the left frame side rail...insert a screwdriver...turn the shaft counter-clockwise to engage the gears.” (See last two images for complete text and image).

Are there any clearer images of the left running board valance on 1533X2 where we might be able to make out the control lever (knob)?

Like many of the Chev Parts Lists, CC60L-01 uses mostly generic diagrams which do not give an accurate visual representation of the specific parts for the vehicle.

The Driver’s Handbook series are well illustrated.

Again, acknowledging that only some images from CC60L-HB1 may give a reasonable representation regarding 1533X2, here are some images that may be beneficial.

Here are a few more images from CC60L-HB1 that might be useful, and the last of my “blast of info” for tonight.

I have re-read the entire thread and note that the info on page 37 of Volume V of the Design Record has not been included.

I note the discrepancy between the 133” wheelbase that has been quoted a number of times and the Design Record entry of 134 1/2”.

I have also included an image of “Maximum Vehicle Speeds” from CC60L-HB1, as the question of speed has come up in relation to two-speed rear axles.

Hi Colin
This is great, thank you for sharing this information.
Reference the PTO air pump controls, I have over 300 photos of 1533x2 trucks in LRDG service and I can confirm that I have yet to see a control lever by the air hose connector. All evidence points towards the control lever being in the floor, activated by a screw driver.

Great scan of the waterfall grill, is there any more information and/or diagrams of this area. I'm interested in the bumper brackets and support rods details.

Actually I'm interested in as much information as possible as the 1542/1543 parts books seem to be the only useable references specific for the 1533.

Your 1542/1543 parts books area little goldmine of information!

I note that in post #184 in the 'Description of body' it states that "STANDARD tool boxes are provided", which I take to mean that these are to some extent universal, which would fit in with the suggestion that they are the same as used on CMP C60L trucks made in an earlier post.
