Using tools safely

Never use a wrench which fits the nut poorly. This practice batters nuts and spreads wrenches. Use correct size wrench.

 

Using a vacuum gage to diagnose WW2 jeep engine problems?

The vacuum gage can tell you much more then a simple compression check.

See How to Master the Vacuum Gage

You may not have a port on an early manifold. Army Motors told the troops to drill a hole or the vacuum part. And I reckon to tap it for a plug as well. As an alternative you could fashion a spacer with a vacuum port for those jeeps that don’t have a port…and when you don’t want to drill a port.

 

What’s a good tool list for WW2?

If you have my book “Military Maintenance” (available from lulu.com and most major bookstore chains) it provides a description of what is in Standard Nomenclature List (SNL) G-27.  “Ordnance shops will get most of their information from SNL G-27, including the basis of issue for special tools.  Basis of issue for unit equipment sets of 3rd and 4th-echelon tools is contained in the organization’s T/O&E, but details of the sets are published in G-27.  In addition you can find pictures of special tools in SNL G-175.”

More on the subject?

“Organizational Spare Parts and Equipment (OSPE).  These are individual pamphlets for each make and model vehicle.  They tell what tools the vehicle itself carries (first-echelon tools), and what special tools the second echelon will need to maintain it.  OSPE’s are used as a basis of issue.”

“Tool Sets, Motor Transport (SNL N-19).  This one has a tool-by-tool listing, with pictures, of everything in the second-echelon unit equipment sets (including the Armored Command sets), plus the hand-tool kits of general automotive mechanics and automotive specialists.  It’s good only for identifying the tools in the sets; the basis for requisitioning sets is company’s T/O&E.”

BANTAM, FORD AND WILLYS—1/4-TON RECONNAISSANCE CARS

By Robert Notman

Paperback, 170 pages

Price:	$24.95 plus shipping

Ships in 3–5 business days

The 1/4-ton, 4×4, truck of World War Two started out in the hands of the Infantry and a little company called American Bantam Car Company. Bantam worked with the Army’s Quartermaster Corps to produce the pilot model that was accepted and then fulfilled their initial contract for 70 trucks. During testing of the pilot both Ford and Willys-Overland were invited to check out this new vehicle. The vehicles were studied in great detail. Soon, at their own expense, Ford and Willys-Overland submitted pilots for testing too. This book covers the production prototypes–Bantam BRC-40, Ford GP and the Willys MA.

This book is available through major book sellers and Lulu.com.

Which Tool List for WW2 jeeps and other vehicles?

Original from WW2 Army Motors….

A round-up of SNL’S . . . six different kinds carry tool information.

Do you ever just sit around and wonder about tools and tool lists? I do. Here is some lists and info that I’ve found. ..why not ponder this list?

Every afternoon our office boy rushes in with a little white pamphlet, tosses it on our desk, and screams, “Latest tool list, Jackson.” And every afternoon we throw the latest tool list whizzing past his left ear, to a mounting pile of latest tool lists we keep in the northeast corner of the office. This morning we decided to sort out the pile. We found not one, not two, but six different’ kinds of tool lists, all published in SNL’s. And you in the 1st and 2nd-echelons are supposed to be using at least two kinds, maybe three or four.

Some of them cover common tools (that is, tools you can use on most all vehicles), and some cover special tools (designed for one vehicle, but maybe interchangeable on a few others).
Some are used as a basis of issue (mention ‘em and you can have anything that’s legal), and others aren’t. For those’ that aren’t, the Table of Organization and Equipment (T/O&E) is very often the basis of issue.

These are what we found:

1) Organizational Spare Parts and Equipment (OSPE). These are individual pamphlets for each make and model of vehicle. They tell what tools the vehicle itself carries (first-echelon tools), and what special tools the second .echelon will need to maintain it.
OSPE’s are used as a basis of issue.

2) Tool Sets, Motor Transport (SNL N-19). This one has a tool by-tool listing, with pictures, of everything in the second-echelon unit equipment sets (including the Armored Command sets), plus the hand-tool kits of general automotive mechanics and automotive specialists. It’s good only for identifying the tools in the sets; the basis for requisitioning sets is the company’s T /O&E.

3) Special Tools for Combat Vehicles (SNL G-175). Here’s where you find an ABC list of all tools used by any or all echelons for maintenance of combat vehicles. It has pictures, tells the stock numbers, piece-mark or drawing numbers, and SNL numbers for each and every tool. It is not a basis for issue (use the OSPE instead). Sorry, but there’s no publication like it for transport vehicles at present.

4) Interchangeability Chart of Organizational Special Tools for Combat Vehicles (SNL G-19).

This baby tells you how to save weight in your 2nd-echelon tool load, and at the same time help to avoid tool waste. It’s a cross reference to special tools that can be used on more than one vehicle. For instance, if you already have an idler-wheel puller (41-P-2940800) for maintaining the M12 Gun Motor Carriage, this SNL tells you the same tool will fit 15 other motor buggies. Like G-175, this one is for combat vehicles, and is published for information only. It is not to be used as a basis of requisitioning.

5) Tools, Maintenance, for Repair of Automotive Vehicles (SNL G-27) is a 3rd and 4th-echelon publication, for Ordnance outfits only. It lists their unit-equipment sets, their special tools for component parts of vehicles (such as voltage regulators, brakes, etc.), their special tools for specific makes and models of vehicles, and a few additional kinds of special equipment. This publication is a basis for requisitioning and issue of all special tool sets allowed to Ordnance organizations for maintenance of combat vehicles.

6) Shop SNLs. These give complete tool lists for certain types of shops-all of them Ordnance shops, with the exception of SNL N -23, which covers unit equipment for posts, camps, and stations.

So you see, gentlemen, this is what you will need:

First echelon:
For your vehicle tool set-the OSPE for your vehicle. It provides a basis for requisition, and identifies the tools with stock numbers and pictures.

Second echelon:
If you have transport vehicles only, you’ll need your organizational T/O&E (as basis for requisitioning unit sets of common tools), SNL N-19 (for details of the tool sets), and each vehicle’s OSPE (as basis for requisitioning special tools).

If you service combat vehicles also, you’ll need in addition to the above, SNL G-175, which gives pictures and full identification of special tools for combat vehicles; and SNL G-19, which gives you the dope on interchangeability.

Ordnance shops:
Ordnance shops will get most of their information from SNL G-27, including the basis of issue for special tools. Basis of issue for unit equipment sets of 3rd and 4th-echelon tools is contained in the organization’s T/O&E, but details of the sets are published in G-27. In addition, you can find pictures of special tools in SNL G-175.

If your outfit is covered by a shop SNL (and they’re rare-but consult the new OFSB 1-1 for the list), that will be your Bible, of course.

 

How about a complete Motor Vehicle Mechanic’s tool set?

You are certainly looking at a large task to collect 88 different tools including the toolbox.

I like to have the right tool for the right job–don’t you?

Among other things you will be looking for a saw, hammers, feelers, hammers, screwdrivers, several punches and a whole bunch of wrenches. Here is a version from my website:

And here is the list!

 

WW2 tool to make assembling the T-84 jeep transmission easy!

Tool used to assemble the cluster gear.

Those of you familiar with my earlier work will recognize the drawing above from, Military Maintenance for MB/GPW jeeps 1941-45.  It is not my intention to duplicate that work here but to bring into this discussion of transmissions those portions that may be appropriate.

While assembling the lower part of the T-84J is not impossible to do without this tool it is certainly easier.

The tool is easy to make, any machinist should be able to whip one out for you in no time. Mac McCluskey is a skilled machinist who agreed to make a copy of the above tool for our testing.

Having the right tool is a good idea–isn’t it?

Dear Editor,

We use a tool that can be made very easily and saves much time and profanity when there are 1/4-ton jeep transmissions to work on.

To line up the thrust washers on the countershaft, which must be set in the case before the clutch shaft can be installed, use a tool of the dimensions shown in the Fig. above.

The tapered end of the tool will pick up and aline the washers. It’s .OO2” smaIIer in diameter than the countershaft and slides through the clusters easily.

The countershaft is used to push the tool through. Since both tool and shaft have flat ends, the washers arc picked up smoothly by the shaft and are not bent or chipped.

T/5 Robert E. Bayes

APO 298

Ed. Note-Good idea—in fact, it’s similar to what the manufacturers use. A little grease on the washers helps to hold them in place during assembly.

You might also be interested in our book, Trouble Shooting and Repairing the T-84 Transmission. I wrote this book to make it easy for the average shade tree mechanic to work on the WW2 jeep transmission.  Why it was almost fun!
