Hour Meter tachometer cable broke SC2400

[CaptFerd]

When I saw this I was for certain that this was the result of another problem. I tried turning the cable in the meter box and sure enough it was froze up. This is how I fixed it.

You need to remove the dash cover and bar across the top. Disconnect the battery. Pretty strait forward just find all the screws and bolts and remove them. Unplug and take out the emergency flasher button. 2 screws are hid under the rubber gasket surrounding the steering wheel.

Unplug all the wires under the dash and remove the cover

Be very careful handling the meter box. Some parts inside are delicate and will break easy. Remove all the screws you see in the picture above. This removes it from the case, removes the gearbox, and rear cover.

Remove the 3 screws marked ground these hold the gas meter. On the other side remove the screws holding the front cover. The assembly will come out the front. Handle with care

(The gear on this shaft was removed to show the problem area) Where the shaft goes through this bushing is where it froze up. With some 3 in 1 oil and by slowly working the shaft back and forth You can free the shaft. Soak it with oil over night. Be careful not to get the oil anywhere else. You should be able to spin the shaft with your fingers and make the RPMs needle move. On older meters where the grease on the gears is dry. You can clean them and re grease if necessary.
Reverse the procedure to install. Install the cable to the meter before you put the dash cover back on. A little easier to do this way.
Hope this helps someone. Could save you a few hundred bucks.

Great job, thanks for sharing! I will show these pictures to a coworker tomorrow, he has a SC2400 and will be interested in seeing them.

I've removed the dash cluster from my LX before, its a similar process and of similar construction, but the tach cable does not run into it so there are only wires to disconnect. These pictures would also be helpful for someone trying to get into the instrument cluster to change out a burned out light bulb. Un this picture the blue and black light bulb holders are visible, just twist out the old bulb and insert a fresh one.

I've also replaced a tach cable on a 1966 2.5 ton Army truck before, I could plainly tell this was a more delicate operation, handle with care indeed!

Nicely documented fix!
I was wondering where you stood on the issue.
I wish you many more hours of trouble-free seat time!

My offer stands on any parts/tractor assistance in the future.

Here's some documents from the tech manual that might help others.

Anyone have part numbers and availability of a replacement cable? I also need a replacement angle drive as well as the plastic gear on the back of the meter box. The angle drive is the black item on the back of the meter box in the picture. The gear on the back of the meter box connects to the gear in the angle drive when it's installed. The tach and hour meter run well but the two gears destroyed themselves. As soon as I have the part numbers of the needed items, I can try to locate a source. Any help you can provide will be very much appreciated.

Good Luck and if you have any please reply to or repost - My green helical gear at the inst cluster has a couple broken teeth. I have searched hi and lo for a gear - the whole inst cluster is not available - manuf says discontinued - I don't think they ever made any spares. May have to go to an electric tach and hour meter.

Still looking for a solution. If you go the electric tach/hour meter way, please let us know the details, particularly if your replacement can be fit in the gauge assembly on the tractor.

Does anyone have an inside contact at Cub or Yanmar that might tell us where they purchased the parts we need. I doubt if they manufactured the pieces. If we know the original equipment manufacturer and the part numbers, maybe the parts are still being used elswhere.

Has anyone sent an email to Yanmar asking about the parts needed? I have contacted them in the past about warranty issues and they were very helpful. Just an idea.
