Sherman Tank Site News Post 17: 

Sherman Tank Site News Post 17:  Summer is here, I have all kinds of content for updates, but less time than I would like. 

I am always tweaking the site and doing minor edits, but in the past few weeks, I’ve had time for some more major projects. There have been a few minor projects worth noting as well.

The Editor over at  Tank and AFV News sent me some very interesting reports that give a very interesting look into the Army’s search for a suitable tank Motor.

THE NEW REPORTS! (They are new to the site, not new)

Ordnance Development of the Wright-Continental R-975 Radial Engine: This report is very interesting. It shows how long, and just how far the Army and Continental went to try and improve the life of the R-975 tank motor. By the time they were done, it was almost a new motor, but still not a great tank motor. Good enough for sure, but no Ford GAA, or as reliable as even the A-57!

Ordnance Development of the Chrysler a-57 Multibank Tank Engine:  This report is just like the one on the R-975, but all about my favorite tank motor, the Mighty A-57! This motor became shockingly reliable for how complicated it was. What made it great was the complication only came in mating the five motors, the banks themselves were solid, wells designed, motors.

Ordnance Development of the Ford Tank Engines: The same report, this time for the Ford GAA, GAN etc. Very interesting, the GAA had a lot of developmental bugs. Aircraft motors, even Vs do not always make the best tank motors.

Ordnance Report on all Army Diesel Engines, June 43:   This report is not exactly like the three above, but close enough. It is a very interesting look into the GM diesel program and the other oddball diesel.

Memorandum on Tank motors: This report is more of a summary of the Tank motors as of mid-June of 1942.

These reports will give you a very good look into why the US Army chose the motors they did and the story behind getting each one to work as a tank motor. They are interesting stories in their own right.

Sherman Tank Site Post 74: A  Guide Through The Maintenance Maze

While I was poking through some old issues of Army Motors, I ran into this fascinating little guide to the Armies maintenance system. Most people who have not dealt with some kind of large motor pool have no idea the large maintenance tail a big number of tanks or even trucks has.  A hell of a lot of men and equipment are required behind the front to keep the 5 men and their Sherman running in combat.

I thought this would be a good place to link to the new paper put out by Arthur Gullachsen on the Canadian Military History site. The report is called No Shortage of Tanks!: THe Canadian Army’s SYstem for the Recovery Repair and Replacement of A and B Vehicles and Major Weapons Systems. 

This fascinating report gives a very nice overview of the Canadian version of the echelon Maintenance system. Between the Army motors article and Arthurs Report, it covers just about any questions I could have come up with on how the Allied maintenance systems were run.

Special thanks to Hanno Spoelstra of the Sherman Register for finding the report!
