Running back an hourmeter

Bought this tractor last fall. Realized that I had been running it for nearly a year without the hourmeter recording. Tach cable broke which is what attracted my attention to it.

Installed new cable and decided to add some hours to try to make the thing more accurate.

Hooked the cable to a drill and away we went. The tach ran up to 2000 rpms and the hour meter went merrily on it's way recording time just as if the engine was running at 2000 rpm's.

So I got curious. How do the cheaters cheat on things like that and back in the old days running speedometers back?

From what I observed you ain't gonna get there from here cause they lap just like you put them on....so to add or remove say 100 hours you would have to run the drill 100 hours, or in the case of a car to take off 10,000 miles you would have to run the drill the equivalent time to cover that distance at whatever speed you were indicating.

Funny, I heard about it all my life but just now wondering how it was done.

the old ones could be taken apart and the numbers reset to anything you wanted. at the dealership we had a list of how many miles a car should have on it depending on age.if anyone asked we were to tell them that it was broke and we fixed it. by the way txgrn this happened about 20 miles south of you. HHHHMMMMM MMMMmmmmm

Well when I use to buy used cars I'd look at the brake pedal especially looking for wear especially on the lower right corner where your foot slides off.

Later in life when I could afford a new one, I would look at the wear on my pedal and the odomoeter and attempt to see of the guys who sold me used cars cheated or not.

Thanks,

Mark

I worked at a Harley-Davidson dealer back in the seventies.One day some kids broke into a storage garage and stole three Yamaha dirt bikes.They were IT models,off road but lights and speedo equiped.When the kids got caught each bike had about forty miles on the speedos.The owner was in his office all day for a week or so with a drill in reverse.Everytime a mechanic walked by they would yell to the owner"Bill those are used machines now" He would yell back,"No way am I taking a loss because of some punk kids." It was actually pretty funny to see the grouchy jerk winding away for days on end.So I think it takes alot with the reverse drill method.Good luck.

I had a 1973 Gran Torino Sport with 83 thousand miles on that I wanted to trade on a new 1976 Pontiac Grand Prix, took it to the dealer, and he was only go allow about 1100 on a trade. Next stop was the Ford Parts Counter, bought a new speedometer, had a garage set it at 38K miles, drove the car up to Robstown, TX and bought a demo Ford Torino Elite.
The salesman couldn't believe it only had 38 thousand some hundred miles on it, I said I had a company pickup, and only drove the car on my days off, got a much better deal, but got screwed on the quality, or lack thereof, on the "new" car.
Rule 1. Never buy a demo
Rule 2. Never do something like this and deal in your own backyard.
Unanswered Question: If I had bought the Pontiac, would I still be driving GM today?

Rule 3. don't be dishonest and screw not only the dealer but perhaps the next poor guy that buys that car from the dealer.

Rule 4. what comes around goes around.

Most vehicles from the '20's through the early '80's had a speedometers with a drag cup movement. To set the odometer back take the drum apart, set whatever mileage you want and put it back together. It is kinda like a rube cube, everything has to match but you can get any mileage you want with some patience. The problem is that the reels are plastic and any out of synch wear or the slightest wrong contact and the digits won't read out in a perfect line across after it has been installed for about 1000 miles, some digits will be higher or lower than others.

Nope, I don't make a practice of turning back odometers or hour meters, just have repaired many. I can spot a rollback in an instant and so can any instument repair person.

On cars what can (could beins they're electronic now) get you is if some filling station had put an oil change sticker on the door sill with mileage and date on it..... ....

I am a firm believer in rule 4. I have witnessed it many many times over the years and it really does work. I also believe in an old saying my dad taught me "If you never tell a lie, you dont have to remember what you said".

You don't need to run them back just leave them unhooked,or put in a new one.I hear that the older cars were extreamly easy to take the speedo apart and roll back the numbers.Or you could do like the State Trooper I heard about get a ratio box made that only runs it at half speed---wala half the miles !

Todays elctronic speedos record the miles forward even when going backward.
