Introduction 20220422N 5 1 INTRODUCTION Note ! This manual does not cover a previous model RPU80 with serial numbers 101-248. The model is covered by the RPU100 Reversible Pump Manual. Minor modifications where made to the RPU100 model and they are described in a separate "Technical Information" no.
Simrad Reversible Pump RPU80/160/300 6 20220422N An automatic "Rudder test" function in these autop ilots will also limit the output equ ivalent to a rudder speed of 8 degrees per second which is optimum for aut opilots with proportional rudder control.

Simrad Reversible Pump RPU80/160/300 14 20220422N 3 DESCRIPTION OF RPU80/RPU160/RPU300 3.1 Construction The pump comprises an electric perm anent magnet m otor, valve block with reversible gear pum p, non-return (ch eck) valves on outlet A and B and suction valves from both sides of the gear pump to outlet C.
Description of RPU80/RPU160/RPU300 20220422N 15 3.2 Principle of operation (ref. figure 3-1 and figure 9-1) RPU80/160/300 is reversible: that is the motor changes direction of rotation and the gear pump deliv ers oil to that side of the rudder cylinder dictated by the signal from the autopilot.
Simrad Reversible Pump RPU80/160/300 16 20220422N 3.3 Valve block This is an aluminum block with borings for no n-return valves, suction valves, slide, gear pump, motor coupling and all necessary oil ways. The three out lets A, B and C are positioned on top of the valve block.
Description of RPU80/RPU160/RPU300 20220422N 17 3.8 Pipe connections The 3 outlets have fittings for 3/8" (US model) or 10 mm (EU model) outer diameter pipe. The two outer outlets A and B connect to the main pipes. The middle outlet C connects to the bottom of the expansion tank in the steering wheel pump or a separate expansion tank.

Installation 20220422N 19 • Use the fingers and turn clockwise until a noticeable increase in torque is required. • Tighten further by 30 degrees (= 1/12 of a turn) using necessary force (25-30 Nm/230-260 In.Ibs). Pumps with new fittings have got new serial no.
Simrad Reversible Pump RPU80/160/300 20 20220422N A clearly formed lip should be visible on the pipe in front of the cutting ring. If this is not present, the nut should be tightened by an additional ½ - 1 turn. Check once again as above. From the T-couplings run a pipe 10x1 mm (US model: 3/8"), to the pump unit.

Installation 20220422N 23 5 PREPARATION AND TESTING 5.1 Oil filling and bleeding When installing a pump unit, it is recommended that the whole system be emptied and refilled. Use a well known oil of a viscosity meeting the specific ation of the steering gear manufacturer.
Simrad Reversible Pump RPU80/160/300 24 20220422N 6 MAINTENANCE 6.1 Dismantling After approximately 1000 operating hours, the pump unit should be removed for examination. Close the stop cocks to the pump unit, remove the nuts on the 3 couplings and all retaining nuts.
Fault tracing 20220422N 25 7 FAULT TRACING If fault develops, the so urce and location must be traced. Close all stop cocks to the pump unit and check whether the steering gear functions normally using only the steering wheel pump. If so, then the fault is most proba bly in the pum p unit or junction unit/autopilot computer.
Simrad Reversible Pump RPU80/160/300 26 20220422N 7.4 The rudder does not stay in off-midship position, but drifts towards midship due to water pressure on the rudder Probable reason (Does not apply for the previous model of RPU80): 1. The non-return valves are leaki ng.
Fault tracing 20220422N 27 7.7 Rudder movement stops as water pressure on the rudder increases. (J1000B, J101A, J45A only) Probable reasons: 1. Overload. Check whether the r.p.m . of the mo tor is too low. Eventually turn potentiome ter RV1 in junction unit clockwise (CW) until rudder m ovement is recovered.
Simrad Reversible Pump RPU80/160/300 28 20220422N 7.10 Rudder moves only in one direction (with pump running) Probable reason: Suction valve not working (pos. 20, 9, 21) on one side. This is most probably caused by metal fragments that have entered into the suction valve(s) through the tu be fitting for the return line (C) during installati on.
