This KaMeWa Controllable Pitch Main Propellers Description and Service Manual, document 0324, is the complete technical reference for the KaMeWa CPP system installed on Nordsovaerftet Hull numbers 217 through 220. Across roughly 290 pages, the manual brings together the propeller hub design, the shafting and push-pull rod arrangement, the pitch setting mechanism with its oil distribution box, the hydraulic power pack, the electronic remote control system, and the Simplex-Compact shaft seals — aft seal Type SC 2 BC and forward seal Type SC 2 Z — in one place. The document opens with the KaMeWa propeller concept and a section on hydrodynamics and optimization, then moves into the detailed technical data: hub size 94 KS/4, propeller diameter 3900 mm, four blades, NiAl-bronze hub and blades, SKF coupling OKFB 280 HB, pitch setting mechanism Type 500 B, and weights for the hub, blades and propeller shaft. From there the manual works through the hardware in the order a service engineer would meet it — hub, shaft, OD-box, hydraulics, electronics, seals — before closing with mounting and dismantling, installation, and the spare parts lists for the hub, shafting, pitch setting mechanism, OD-box, hydraulics and remote control.

For anyone maintaining or overhauling a KaMeWa controllable pitch propeller, the sections that matter most are the ones that carry numbers, dimensions and procedures: the tightening torques (hub cylinder screw 450 Nm, shaft flange screw 4550 Nm, blade flange screw 4550 Nm), the blade sealing ring O-ring dimension 514 x 17, the emergency pitch setting instructions for both Level I and Level II situations, and the B+V wear-down gauge measuring procedure for checking propeller shaft bearing clearance. The seal chapters cover the full Simplex-Compact story — how the aft and forward seals are built, how they are installed with the propeller shaft drawn in from either the inside or the outside of the vessel, how the anodes protect the chrome steel liners against corrosion, and how sealing rings are exchanged either with a bonding device while the ship is afloat or in the workshop with the seal removed. The lubricating oils and lubricants list gives the approved grades for Perbunan and Viton sealing rings, and the filling quantity tables give the exact oil volumes for the aft and forward seal chambers across the full range of seal sizes.

The hydraulic and control sections explain how the pitch setting mechanism actually works on this installation: the Type B working principle, the oil distribution box, the feed-back box with its zero pitch indication cam, micro switches and potentiometers, the hydraulic power pack with its double pumps, booster valve, proportional valve and cooler, and the electronic remote control system with its central unit, bridge control panel, ECR panel, load control, RPM indication and back-up manoeuvre system. Operating instructions for both bridge and engine room staff are included, along with the trials programme, start-up and flushing instructions for the hydraulic system, and the instruction for cleaning hydraulic pipes. The mounting and dismantling chapter covers the KS propeller — blade removal and refitting, blade sealing ring replacement rotation, tightening and locking of screws — and the OKFB shaft coupling mounting and dismounting procedure with its hydraulic pump, oil injectors and drive-up dimensions.

Because this manual was written for a specific build — Nordsovaerftet Hull No. 217, 218, 219, 220, KaMeWa manufacturing numbers 1443-1446, serial numbers 60109-60112 — the drawings, dimensions and spare parts lists in it are tied to that equipment. Anyone working on a similar KaMeWa CPP installation will still find the principles, procedures and most of the service data applicable, but the exact part numbers and build dimensions should be checked against the specific unit. The manual is built around drawings and diagrams: hub assembly, shafting arrangement, OD-box assembly, hydraulic diagram, hydraulic power pack, feed-back box wiring, remote control cable diagrams, control panel layouts, P/D-n diagram, and the anode dimension tables for both ring and block-shaped anodes.

What This Manual Lets You Do

With this KaMeWa Controllable Pitch Main Propellers Description and Service Manual on hand, a marine engineer or service technician can work through the full range of jobs on the KaMeWa CPP system: understand how the hub, crosshead, sliding shoe and crank pin ring translate push-pull rod movement into blade pitch; set up and adjust the oil distribution box and feed-back box; commission the hydraulic power pack and set the safety valves; test the remote control and back-up manoeuvre systems; carry out the emergency pitch setting procedures if the hydraulic or electrical system fails; check shaft bearing clearance with the B+V wear-down gauge; replace blade sealing rings and shaft seal sealing rings; install and remove the aft and forward Simplex-Compact seals; protect the propeller and seals against corrosion; and find the right spare parts from the parts lists. The procedures are written for the shipyard and the ship’s technical staff, with the torque values, oil quantities, tolerances and measurement points needed to do the work correctly rather than by guesswork.

Getting these procedures and specifications right matters because the KaMeWa CPP is a precision hydraulic-mechanical system: the wrong tightening torque, the wrong oil, a mis-set end position or a damaged sealing ring can lead to oil leakage, loss of pitch control, water ingress into the hub, or damage to the OD-box and feed-back components. The manual’s measured stroke tolerances, filling quantities, pressure test values and wear-down gauge reference figures exist precisely so that the work can be done to specification and the equipment can be returned to reliable service. The emergency pitch setting section alone is worth having aboard, because it describes how to bring the propeller to full ahead mechanical end position using the hand-operated emergency pump when the normal system is out of action.

IMAGES PREVIEW

Delivery is instant: this KaMeWa CPP service manual is supplied as a PDF download, no shipping and no waiting for a physical book. It can be opened on a laptop, tablet or phone in the engine room, on the bridge or in the workshop, and pages can be printed for use at the shaft or on the dock. The file keeps the full manual together — cover, contents, all chapters, all diagrams, all tables and all spare parts lists — so the information you need for a job is in one document rather than scattered across separate sheets.
