MF135 Tach/hour meter problem

I have a MF135 deluxe that my great-uncle bought new in 1967. The hour meter stopped working at 919 hours, however the tach still works just fine.
Is there anyway to fix this? Or would I need to buy a new tach/hour meter? I am assuming the cable attached to it must be fine since the tach still
works. Thanks.

If the tachometer works there must be something stripped in the hour meter gearing. Probably could be repaired by a shop that works on them but it would be more cost effective to replace it. Aftermarket ones can be bought for less than $50.
 
Hello,
Would certainly agree with Phil on this one. These clocks are not worth trying to repair. In the UK a non-Multi-Power clock at today's exchange rate can be had for $36.90 and a MP clock for a 135 for $51.66 including our 20% purchase tax.

Can the tach be replaced without removing the dash? Is there enough wiggle room to remove it from the underside?
Thanks
 
I have been looking online for a replacement tach but none of them look like the one on my tractor. Is the style of my tach still being produced or will I need to switch to a different one? These replacement dashes look so much more complicated than the simple one that is on my tractor. I am planning on calling the dealer tomorrow to see what they say.
thanks.
 
The replacement tachs all seem to be standardized and look the same. Not much choice if you want to stay with the mechanical driven one.
 
After you remove the bracket on the back side that holds it in, the tach will come out towards you if you are sitting in the seat of the tractor. You can take the battery out to get to the back side of the dash much easier. There is also places that restore gauges for old cars. Those places can fix the "mileage meter" in speedometers so a hour meter shouldn't be that much different.
 
(quoted from post at 20:01:47 03/20/17) After you remove the bracket on the back side that holds it in, the tach will come out towards you if you are sitting in the seat of the tractor.

I had the battery out once on the 202. You can't see the backs of the gauges from there. It is a solid piece of metal. That's why I was wondering how much disassembly I'd have to do to get at them.
 
I just got off the phone with my local Massey dealer. They told me the only part number available is 1078005M91. Agcopartsbook lists two different numbers for the tach but both numbers have been replaced by this one. They want $114 for looks like I can get online for about $40.

This may be a dumb question, but I do not see where this new tach shows you the rpm of the pto? The tach I have now has right on the face 540RPM, which is what I use when I am mowing or using the brush hog. How does one adjust the RPMs to 540 using these newer tachs?

Thanks
 
Ignore that last post. I had to turn my monitor upside down, but I see where the new tach does indeed say 540RPM on it. Odd why they have it printed upside down.
 
Transfer the pto range marks from the old tach to the new one with a paint pen. Otherwise you have to get that double needle tach that seems to be universal replacement.
 
The British Standard Belt & PTO speeds are on the lower half of the dial because that is in the speed sector for low range gears, where they thought back in the day you would only use the PTO in the low range. That type of revcounter is called a 'Tractormeter', they were made by Smiths industries and were standard equipment on the Coventry built 135, Ford Super Majors and Dextas also had them
