I have a YM2820 with what appears to be a broken tac drive cable. I purchased the cable from a dealer out of state as well as a shop manual and and operators manual. There is no reference to the tac cable replacement. Can anyone give a brief run through of the proper procedure? I am limited in my experience with this type of repair, but am very mechanically able. How much of the sheet metal/ side panels or dash has to be removed to facilitate this repair?Thanks in advance for any help.

I am not familiar with the YM2820 but I have a JD 950 that was made by Yanmar. Don't know how similar they are. I replaced my tach cable not long ago. I only had to remove a small access panel under my dash to reach the bottom of my tach. The other end of the cabel attached at the front of the engine so all I had to do was raise the hood. Then it was just a matter of threading the cable from the engine thru the firewall to the tach. ....

I can say what I did on my Ford 1710, but that may be some different than proper procedures for a Yanmar.
I was able to remove gauge end mounting nut by hand or small pliers without disassembly. There was enough space for my hand between the console and fuel tank. I then pulled on the centre wire to see where the cable was broken. It was broken about a foot from the gauge end so I didn't have to worry about pulling the drive end and leaving a broken cable in the drive or something dropping into the timing gear case. I then, removed the drive end (I don't think it even took a wrench) and threw away the old cable. I pulled the centre wire out of the new cable and slobbered white (speedo cable) grease on it and installed it.
The brake was cause by a previous professional repair to the steering column. The console had been pushed forward over the fuel tank without removing the cable, which caused a crimp in the cable. I don't think it's common for a cable to fail due to old age, and I might wonder what caused the brake unless something is apparent like there was on my Ford..
