The tachometer on my 5300 has stopped working. I have cheked the fuses, replaced the instument cluster and the voltage regulator on the alternator without success. Is there some other component between the regulator and the tach that could have failed?

Mine stopped working at 1 point. The connection came undone from the back of the tach.

On Friday the tach on my 6 month old JD 3320 went south as well. Operation seemed normal except RPM would not register over 2300. At first I thought maybe some linkage had slipped, but as time progressed the actual tach readings became erratic - e.g. at quick idle reading showed 0 RPM.

Called the JD store to set up for appointment. Service guy tells me "most guys don't pay any attention to tach anyway" I say "sure when I'm paying the bill maybe I won't either, but seeing it's under warranty it's getting fixed."

Also need them to look at the Rockshaft - is about 3/8" short of full lift to insert pins to hold backhoe in place. Also needs to go down about 1" further so I-Match can engage pins on BB when sitting on flat level floor.

There is a small sensor on the left front side of the engine near the water pump. Sometimes it go bad. I replaced mine once, was about $25-30. Easy to replace. Otherwise it may take a whole new instrument cluster which you have already replaced.
