450 Case tach drive

[304thomas55]

I bought a 450 Case a few years back and most of the gauges aren't working. The tachometer is missing too. Where does the tach drive attach on motor ?

Gas or diesel engine ?
Case gauges don't get any cheaper than these.

case 450 never had a tach just a plug where the drive would go

My 450 is diesel.

Reference #30 is the tack. drive. You may find a used one in a farm equipment salvage yard if you need one.
Do you have a service manual ?
This is a copy from the service manual.

Something else I'd like to ask, hydraulics on blade drifts while in operations. Fluid level is good. Pump or relief valve?

Most likely a leaking piston seal in one or both of the blade hoist cylinders.
