Description of Change: A new waterproof tachometer is now available.
Adaptable To: The 119-7248 Tachometer has been replaced by the 149-7208 Tachometer/Service Gauge Gp. The 149-7208 Tachometer/Service Gauge Gp is a part of the 246-3256 Parts Kit (TACHOMETER).
The 121-2551 Instrument Panel Gp is used in irrigation systems. The 121-2551 Instrument Panel Gp has a 125-0845 Box that holds 119-7248 Tachometer. The 125-0845 Box is not waterproof. This can enable water to damage the 119-7248 Tachometer .

The 246-1435 Cover will deflect water from the tachometer on engines that are used in irrigation systems. Also, the 246-1435 Cover can be used on the 125-0845 Box. The 246-1435 Cover can be installed before the 119-7248 Tachometer needs to be replaced.The new 149-7208 Tachometer/Service Gauge Gp is a waterproof unit.
Note: The 149-7208 Tachometer/Service Gauge Gp also provides an emergency stop command to the engine in case of an engine overspeed.
