Manuals and CCKW ownership

[pfarber]

I have collected many (but not all) CCKW manuals. Some (the mighty Bendy-me-Over) will say that the best and only TMs you need are the later TM9s and SNLs because they are more accurate.... I just want to give my view of what TMs you need and why.

First, you need the TM/SNL/Parts books released with your truck. If you don't have the data plate specifying what they are, its easy enough to find out by date or or Registration number (though not always!).

Second, Originals are nice, but expensive. Get digital manuals so you can print out what you need for the job at hand. For example when I was rebuilding the 28AV11 I had not only the SNL exploded diagram printed out, but also I printed out the TM9-1826C chapter giving step by step directions. I also had TM10-1563 standing by. I also had an original zenith rebuild book for civvy 28AVs as another reference.

But, in mid/late 42 the Army started to move to the ECHELON system of motor vehicle repair. No more were owning units able to perform in depth repair or rebuilding of CCKW components. They were to be simply replaced via the supply system as an entire unit. By mid 1943 the first of the TM9-801 was released and missing was A LOT of technical details regarding repair. It was mainly a preventative maintenance, operation and replacement guide. New TMs were printed for units involved in 3rd and 4th Echelon maintenance: TM9-1801 and TM9-1802A since the specific engine (and transfer and tranny and carb and governor and...) that USED to be the in the TM10's were no longer in the new TM9's

Add in to the TM9s not being as complete as the TM10s the TM10s also have issues... that of multiple engine configurations across multiple contracts... so a later 43 TM10 may be showing parts that were not in production for early TM10s. Its a real nightmare.

But there is an answer

If you have a 1941 CCKW (no, not because the guy on ebay said it was a 1941, but an actual 1941 contract CCKW) you need to have the TM10s (parts and maintenance) for those contracts. Ones that I know of are TM10-1501 and TM10-1500, there are at least 3 others.

What about for all of 1942 and early 43 TMs and Parts books. The latest TM10-1563 maintenance manual is dated March 20th, 1943 and TM10-1562 Parts manual dated 1 May 1943. The next month the First TM9-801 was released on April 12th, 1942 and all that good rebuild and technical data goes buh-bye (well, into two more TMs)

For early trucks this is easy... its two TMs the Maintenance and Parts books assigned to your contract.

If you have a 43-44-45 CCKW you will need the
TM9-801 Operation and Maintenance
TM9-1801- Chassis and Powertrain
TM9-1802A - Engine
TM9-1827B - Hydrovac repair
TM 9-1826C - Zenith Carb repair
TM 9-1825A - Delco Remy Electrical Equipment

Most of these are available in the Technical Manual section off the home page.
