You find a few Olivers with hours that don't match the condition of the tractor. Do the 4-digit tach cables seem to break easily, or do they tend to not get reconnected after repairs?

On the 1850 diesels there's a pin that drives them that breaks if the cable starts to run a little too had. Those pins can be a bear to get out of they break flush. I don't know of any big problem with any other models.

I know on the 1550 gas there is a little plastic gear that drives the tack off the distributor shaft that will brake if not oiled or lubed up every so often. Ours broke 3 years ago and got a new gear to fix it. Sometimes looking at a tractor you can tell how many hours it has on it no matter what the tack says, Then sometimes you look at one that really looks so good and strait you cant believe the high hours on the tack. But most of the time you can tell how they were taken care of good or bad. Bandit

I think there's plenty of other color 40 year old tractors that don't show the right hours. I've heard that gleaner combines
often show incorrect hours.

We have a pair of Olivers (1650 and 1850) with working tachs. However neither tach's engine hour "odometers" have added 0.1 hour in 30+ years of occasional use. So I gotta think there is a weakness in the 4 digit Oliver OEM hour recorders.

My 1850 gas has the worm gear stripped down at the distributor, been that way since I bought it 12 years ago, it is like a woman, stopped counting when it felt like it! LOL

i think josh hit the nail on the head , lots of tractors have tach troubles , lots sit out side there whole life , thats not good
for anything , as far as olivers in my life our 1650 gas & 1655 D , never had hr/ tach problems , but they never spent the night
outside either , my 1855 D, i bought 2 years ago tach & speedo still work , but it looked like it didnt sit out to much in its life
, on the other hand the neibors 4030 & 4430 Deere that sit out, they needed tach cables all the time & 1 dont count hrs when it
does work , gave up on the JD 70 diesel it brakes the tach cable every week it seem like it . ive leaned , if you take care of your
equipment it will take care of you , if not it gets even when you need it most .

My 1650D tach hovers back and forth at the rpm mark, is it the cable doing that or the gear/pin driving the cable? Are new parts still available? - thanks

Donald Lehman · Mar 27, 2015

Our 1650's second or 3rd cable twisted off around, 5500 hrs and we just got sick of replacing the thing. My 1955's cable gave up at around 2200 hrs. never seem to get around to replacing it. Pop's 1355 cable gave up at around 6500 hrs. That thing had at least that many more hours on it when I sold it. My JD 420's tach/hr meter didn't work when I inherited it nearly 20 years ago. Still doesn't. So I think the answer would be that except for a few isolated cases, very, very few older tractors' tach/hr. meters show anywhere near the hours that are actually on the tractor.

I replaced the cable on my 1650 gas. The tach works when I run the cable with a drill, but I think when the old cable seized up it must have damaged the gear in the distributor. So, Brown Swiss, I've never found info on replacing those gears in the distributor. Anyone have any more information about that? (By the way, I'm pretty sure my hours are off by at least 3000, so I'm surprised the tach still works when I manually spin it)

Thanks!

Have you oil the cable?

Grandpa's 1600 broke the original cable back in the late 70's with over 7000 hours on it. The needle pointer was broke too when I rebuilt it so it got a new aftermarket tachometer that's now a little over 700 I think. Probably has well over 10,000 hours. Dad replaced it as the big tractor in the early 80's with our Massey 285.
