Safety* Explanation of signal WARNING Do not allow any body part words for safety to be trapped by equipment. Read and carefully observe these installation Body parts can be crushed instructions before installing/operating/ by subassemblies during troubleshooting the assembly. The assembly operation.
Description* Fig. 1 Model 339005 is part of kit 343683, and is designed to meter motor oils (SAE 5-50), Pulse meter (339005 and 340080) gear oils (SAE 80-240), and automatic transmission fluid. Model 340080 is part of kit 343684, and 2.77 in...
Reed switch rating 120 V AC @ 10 watts chamber. The force of the fluid causes the Flow rate (343683) 0.25 to 8 gal (0.9 to 30 l) ±0.75% internal gear assembly to rotate and forces Flow rate (343684) 1 to 6 gal (3.8 to 22.7 l) ±1.0%...
Function and Fig. 4 Pulse meter overhaul* Refer to Troubleshooting (page 11) to determine where to look if problems occur. Disassembly Switch module 1 Remove screws (2) that secure switch module (1) to housing (3) († Fig. 4). 2 Separate switch module from housing. NOTE Switch module is serviced as an assembly.
Assembly Fig. 5 Pulse meter housing assembly with gears Metering gears NOTE Position gear with magnets († Fig. 5). Before assembly verify gears rotate and do not bind. Manually turn gears through three rotations to verify free movement. Meter will not function properly if gears are incorrectly installed.
Fluid solenoid Fig. 6 Fluid solenoid wiring (343683 and 343684) Fluid solenoid valves contain diodes in their connectors. This diode prevents electrical surges from damaging relay contacts in the keypad controller. Connections at fluid solenoid valve are pre-wired († Fig. 6).
Operation Fig. 7 Solenoid (343683 and 343684) Valve assembly († Fig. 7) consists of two separate internal valves; the primary needle valve and the secondary valve. The primary valve actuates first, causing the secondary valve to operate. When the coil is energized, the primary needle valve lifts and allows fluid into delivery port.
