Does anyone on here have a service manual for a 2605 Massey Ferguson tractor? I just replaced the clutch for a guy and not sure if the tach was working prior or not, but was at least going to try to diagnose and/or repair it as well seeing’s how I’ve already found the water pump was leaking a rebuilt it while it was still sitting in the repair lane. Also not working is the oil pressure gauge. I at least know where the sending unit is for the oil pressure, I cannot find where the engine speed is read on this thing and the www hasn’t been any help so far either.
