My project this morning was to finish derusting these Iola souvenirs, get them working, and oil them. I squandered $3 on them last week.
After getting seriously into the Model T game nine years ago, somehow I never knew about this tool until I saw it at Chickasha this March. 3Z-2034 and 5Z-829 are different (earlier and later) numbers for the same tool. The extra 1" hole on the bottom one for low band adjustment is the first I've seen. All the other examples of the 5Z wrench that I've run across are just like the 3Z version above.
$3 is an impressive release of cash from your Vise-Grip wallet - LOL
I like the one on the bottom as it will fit everything that need adjusting on the Model T transmission.
I have one of those wrenches but i havent used it just yet. Tim
You might also take notice of the slightly "rounded" reliefs in the band nut end of the 5-Z-829 wrench - that fits the low band adjuster but seems to be for the later ? models - most likely when the detachable ear bands came about.
If I find another one with the low band adjuster I may go hog wild and spend up to $5 on it.
Unfortunately a lot of those band adjustment wrenches have poor internal workings and no longer ratchet properly. I have a box in the barn with 12-15 of them and only one works as it should.
Those early ratchet wrench's are good for what they were designed for.
Over time they got used for removing tightened nuts on other types of machinery and were sprung or stripped. Folks on the farm used whatever they had to work on tractors. T screwdrivers and wrench's were in most farmers tool boxes.
I guess I've been lucky with these. Of the five I have so far, only one doesn't work properly (broken spring).
The big end also fits Differential plug and oil pan drain plug.
Those which have the odd hex to fit the low band adjustment don't fit '26-7's, but they are very handy for use on the earlier ones. I have more than 20 different ones, and they all work. (This is an old picture, showing only 19.)
Always good to stock up before the hoarders get them (just kidding)!
