sagefinds Posted February 1, 2021 Share Posted February 1, 2021 It is FORD script although that fact eluded me for a few years. Pretty sure the number is 5-Z-1900. I'm guessing AA or TT rear axle nut,looks like 1 7/16". Anyone know the exact application? Appreciate any help. Link to comment Share on other sites More sharing options...
viv w Posted February 1, 2021 Share Posted February 1, 2021 Pretty sure that wrench is used on the front crankshaft pulley nut on Model A. I have a reproduction one that is very similar in appearance. Viv 3 Link to comment Share on other sites More sharing options...

Mark Wetherbee Posted February 1, 2021 Share Posted February 1, 2021 Model A crank ratchet is correct... I also have used it on a 1931 Pierce-Arrow with great results! 2 Link to comment Share on other sites More sharing options...
Mark Wetherbee Posted February 1, 2021 Share Posted February 1, 2021 I’ll also add that the tool is most useful in getting the car to TDC for setting up timing, or turning the engine to set valves. 1 Link to comment Share on other sites More sharing options...

Mark Wetherbee Posted February 1, 2021 Share Posted February 1, 2021 Pistons going in today... literally just stopped for a coffee in between 4-5 and the next pair going in. Thanks for asking but now I wish there was an OUCH button instead of thumbs up🤣🤣🤣 Link to comment Share on other sites More sharing options...
sagefinds Posted February 1, 2021 Author Share Posted February 1, 2021 You mean those pistons don't want to be shoved into a hole where they'll have to work their little skirts off and they're fighting back? 1 Link to comment Share on other sites More sharing options...
Mark Wetherbee Posted February 2, 2021 Share Posted February 2, 2021 The most problematic issue seems to be getting down and then back up off a cold cement floor... relatively cold, anyway at least for here but thank goodness I’m not in Maine plowing snow these days! All 8 Pistons are now snug in their holes waiting to see what the rodent has to say tomorrow when he crawls out of his... my next argument is getting the oil pump properly aligned So the distributor is pointing the right way. More fun than a barrel of monkeys... Link to comment Share on other sites More sharing options...
Mark Wetherbee Posted February 2, 2021 Share Posted February 2, 2021 (edited) I was just beginning to feel bad about thread deviations... but since it’s your thread and you asked I think it’s allowed🤔 but if it isn’t., I throw myself on the mercy of our awesome moderators and beg forgiveness...
