The heater for the jacket water raises the temperature of the engine coolant and transfers the heat to the block. In cold climates, jacket water heaters aid in starting. The 117-9320 Jacket Water Heater (120 Volt) can be installed on B-series backhoe loaders. The 166-0658 Jacket Water Heater (120 Volt) or the 166-0659 Jacket Water Heater (240 Volt) can be installed in the C-series Backhoe Loaders.

Do not plug in the jacket water heater if the heater element is not immersed in coolant. If not immersed, the heater element sheath may burst and could result in personal injury

Do not use more than a 65 percent concentration of antifreeze, as a shortened heater element life will result. Do not use a heater in a cooling system that contains any form of stop-leak additive, as a shortened heater element life will result.

Jacket Water Heater Installation On B-Series Backhoe Loaders
Illustration 1. Installation of the jacket water heater on a B-Series Backhoe Loader. See Table 1.
1. Drain the coolant from the engine.
2. Remove the pipe plug on the cab heater fitting port just behind cylinder #4. If the cab heater is installed at that port, reinstall the heater line in the 3/8" NPT port.
NOTE: Apply 5P-3413 Pipe Sealant to all threads of pipe plugs, nipples, and fittings.
3. Install the 7M-7410 Pipe Plug (2).
4. Install the 117-9354 Heater (7) into position. Do not twist or bend the 117-9354 Heater (7). Be sure element does not turn while tightening adapter.
5. Connect the black and white wires of the 117-9324 Wire Assembly (6) to each of the insulating terminals on the 117-9354 Heater Assembly (7). Connect the green wire to the screw in the brass retaining nut. Slide the boot over the edge of the retaining nut, completely sealing the terminals, and the plastic block to ensure a water and vapor proof seal.
6. Route the 117-9324 Wire Assembly (6). See Illustration 1. The cord must be routed over the steering line. Secure the wire using the 3S-2093 Straps (1).
7. Mount the 121-7849 Bracket (8) using the 8T-4189 Bolts (3) and the 8T-4224 Washers (4).
8. Push the wire through the bracket and attach the 117-9322 Plug Assembly (5) to the wire. (Place the green wire on green screw. Place the black wire on the gold colored screw. Place the white wire on the silver colored screw.)
9. Mount the plug assembly to the bracket.
Jacket Water Heater (120 Volt) Installation On The C-Series Backhoe Loader
Illustration 2. Installation of the 166-0658 Jacket Water Heater (120 Volt) on C-Series Backhoe Loaders. See Table 2.
1. Drain the coolant from the engine.
2. Remove the lower 1.5 inch core plug from between the #1 and #2 cylinders on the right side of the block. Use a screwdriver and mallet until the plug begins to turn and then pull the plug out with pliers.
3. Clean the hole out with a rag to remove all debris.
4. Insert the 161-8198 Heater Assembly (6) into the hole with the element positioned straight up.
5. Gently tap the Heater Assembly (6) into the block until the flange is flush with the block. Use a tool such as a socket so that the pressure is placed on the flange of the heater.
6. Connect the 161-4150 Cord Assembly (5) to the heater.
7. Route the 161-4150 Cord Assembly (5) and secure using the 3S-2093 Straps (7).
8. Mount the 165-8357 Bracket Assembly (1) using the 8T-4189 Bolts (2) and 8T-4224 Washers (3).
9. Connect the cord assembly to the 130-0165 Covered Receptacle (4).
10. Mount the receptacle (4) to the bracket (1).
Jacket Water Heater (240 Volt) Installation On The C-Series Backhoe Loader
Illustration 3. lnstallation of the 166-0659 Jacket Water Heater (240 Volt) in C-Series Backhoe Loaders. See Table 3.
1. Drain the coolant from the engine.
2. Remove the lower 1.5 inch core plug from between the #1 and #2 cylinders on the right side of the block. Use a screwdriver and mallet until the plug begins to turn and then pull the plug out with pliers.
3. Clean the hole out with a rag to remove all debris.
4. Insert the 161-8199 Jacket Water Heater Element (6) into the hole with the element positioned straight up.
5. Tap the Jacket Water Heater Element (6) into the block until the flange is flush with the block. Use a tool such as a socket so that the pressure is placed on the flange of the heater.
6. Connect the 161-3874 Wire (5) to the heater element.
7. Route the 161-3874 Wire (5) and secure using the 3S-2093 Straps (7).
