Original mechanical hour meter (insert) 704/19705 for JCB machines. This is a key dashboard component designed to precisely record engine runtime. As an insert, it is mounted inside the main instrument cluster. It fits a wide range of JCB machines, including 3CX, 4CX backhoe loaders, telehandlers, and Fastrac tractors. It provides an accurate runtime reading, essential for scheduling service intervals.

The list above is for reference. It is crucial to verify the part number 704/19705 on your old meter insert.
When diagnosing the meter, we also recommend checking the oil pressure switch or alternator (depending on the model), which typically provides the signal. Also check the condition of the wiring harness and fuses.
A non-functional hour meter is the main cause of missed service intervals. Lack of runtime tracking leads to delays in changing engine oil, hydraulic oil, and filters. This can result in catastrophic engine, hydraulic pump, or transmission failure, with repair costs far exceeding the cost of a new meter.
The 704/19705 hour meter is an electro-mechanical insert mounted in the instrument panel. It receives an electrical signal (usually +12V) when the engine is running (e.g., from the oil pressure switch or alternator). This signal powers a small motor that mechanically turns the numbered drums, recording the machine's runtime.

No, this is a mechanical (electro-mechanical) meter. It has physical, rotating number drums, not an LCD screen. This is the original type used in older JCB models.
No, this is the meter insert only. It is the small module that fits inside the existing main instrument panel (gauge cluster) on your dashboard.
This is the most common cause. However, if the meter still doesn't work after replacement, you must check the signal circuit (fuse, wiring, and the oil pressure switch or alternator "W" terminal).
