1.1.2 Preparations

Pay attention to instruction “General warnings and cautions”.

Tools provided with the propeller (see scope of supply for exact WCZP delivery). Lifting eyebolt for propeller. Pressure gauges and high-pressure pumps. Hydraulic hand pump with high-pressure hose.

Check propeller fit on the shaft cone. Make sure that the fit is according to the classification’s requirements. See the procedure “Propeller cone fit procedure”.

All parts that are fitted for temporary protection, such as covers, caps and plates, have to be left in place as long as possible and are only to be removed for immediate connection to opposite parts.

All pipe ends, O-rings and O-ring grooves are to be inspected for damage before mounting.

All temporarily unprotected parts are to be kept extremely clean.

It is advised to start propeller mounting early in the morning in order to avoid temperature differences between propeller and shaft.


procedure





1.1.3 Lift and pull the propeller on the shaft cone

Pay attention to instruction “General warnings and instructions”.

1. Do not unpack propeller hub. Position the propeller at the tapered side of the propeller shaft. Check the port and starboard position if twin propellers, see installation drawings

2. Unpack and clean the propeller shaft cone, check the cone for burrs and damages, repair when necessary, clean and lightly oil the shaft cone.

3. Unpack and clean the propeller bore, check the bore for burrs and damages, repair when necessary, clean and lightly oil the propeller bore.

4. Lift with care the propeller to the proper position in front of the propeller shaft cone. Lifting can be done with slings.

5. Carefully pull the propeller on the propeller shaft cone.

6. Move the propeller on to the shaft until no further movement up the taper is possible.

7. Install the hydraulic nut / ring. The hydraulic nut / ring should have the piston in the fully closed position.

8. Screw the nut / ring to the end of the propeller boss.

9. Remove all plugs of the oil inlet connections in the hub.

10. Provide for all other necessary tools. See instruction “Tools and equipment for (de-) mounting of propeller”.

1.1.4 Determination of the starting point and of the propeller drive up.

For an accurate first determination of the starting point the mounting procedure shall be carried out at least twice.

The starting position when compared between first and second push-up may differ more than 5% of the total required axial drive-up because of the possible bedding action of the fitting process.

Temperature stabilization Time should be allowed to stabilize the temperatures of the propeller and shaft before commencing any push-up procedure. Record the prevailing ambient temperature.

It is essential to commence the push-up process from the correct axial starting point on the shaft. This is achieved by applying an initial start point load with the hydraulic nut / ring without oil injection into the propeller boss. The start point load is given on the drawing “Propeller boss”. The start point load is stamped on the propeller hub as well.

To convert pressure as measured by the pressure gauge on the hydraulic hand pump to a load applied by the hydraulic nut / ring, see the drawing “Assembly hydraulic nut / ring” or to the hydraulic nut / ring suppliers manual.

The appropriate push-up distance has to be determined from the push-up diagram on the drawing “Propeller boss”. When the ambient temperature is measured the belonging push-up distance can be read out or calculated.

Only the axial drive-up distance will give the right position of the propeller. The theoretical mounting force as given in drawing “Propeller boss” is only for guidance to get an indication of the required


procedure





pressure in the nut / ring.

The movement of the piston of the hydraulic nut / ring shall not exceed the maximum value as given on the drawing “Assembly hydraulic nut / ring”.

1.1.5 Push–up the propeller on the shaft cone

• THE INFORMATION GIVEN IN THIS CHAPTER IS FOR GUIDANCE ONLY. THE RESPONSIBILITY

FOR FITTING REMAINS IN THE HANDS OF THE SHIPYARD AND TO THE SATISFACTION OF THE OWNERS AND THE CLASSIFICATION SOCIETIES, UNLESS AGREED OTHERWISE.

1. Bleed all air from the hydraulic nut / ring.

2. Slowly inject oil into the hydraulic nut / ring to meet the predetermined start point load pressure. No oil injection in the boss is required.

3. If the propeller moves up the taper without any significant pressure recorded on the hydraulic nut / ring, this indicates a lack of full mechanical contact between bore and shaft. The tightening of the propeller shaft nut might be insufficient. Tighten the nut and repeat from point 1.

4. When the start point load is reached, set the dial gauge to zero.

5. Inject oil into the boss, with the center vent plug removed, until all air is bled from the center vent hole, then plug center vent hole. Continue pumping until oil bleeds at the forward end of the propeller boss.

6. Record the hydraulic nut / ring pressure and all boss injector pump pressures during the axial movement of the propeller at steps of 1 mm. The pressure difference between the two boss injectors should not exceed 10%, as the pressures become higher. Increase pressure in the hydraulic nut / ring and the boss injectors in the same ratio. Operate all pumps i.e. boss injector pumps and hydraulic nut / ring pump.


procedure





7. When the maximum piston movement is reached release boss injector pressures while maintaining the hydraulic nut / ring pressure, allowing the boss to settle and oil to drain off for a period of not less than 30 minutes. Record the dial gauge reading.

8. Release pressure from the hydraulic nut / ring. Screw on the hydraulic nut / ring till the piston is again in fully closed position.

9. Repeat the procedure as described in 5 and 6. Add new dial gauge readings to the already recorded readings.

10. When the required axial drive–up is achieved, release boss injector pressures while maintaining the hydraulic nut / ring pressure, allowing the boss to settle and oil to drain off for a period of not less than 30 minutes. Record the dial gauge reading.

11. Release the pressure in the hydraulic nut / ring by slowly opening the pump return valve. Record the dial gauge reading.

At first drive up

12. Remove the propeller; see instruction “Keyless propeller demounting procedure”.

13. Fit the propeller by repeating all steps 1 to 11.

14. In case a hydraulic nut is applied, tighten the nut on to the boss. In case of a hydraulic ring is applied, unscrew the propeller nut. Remove the hydraulic ring and screw on the propeller nut again.

15. Tighten the nut with a wire rope around the nut groove to about 1 ton tension.

16. Fit all plugs in the oil inlet connections. Secure by punch mark.

17. Remove the hoisting facilities from the propeller.

18. If applicable, remove the lifting eyebolt and fit the plug. Secure by punch mark.

19. Clean and store all tools and auxiliary equipment.

20. Continue with mounting the propeller cap, connection of the aft seal liner and installation of the rope guard.

1.1 Propeller cone fit procedure

- For installation sufficient space is needed.

- Hoisting facilities must be arranged.

1.1.1 Documents

- Instruction “General warnings and cautions”.

- Drawing “Propeller boss”.

1.1.2 Required conditions

- The shaft hole in the propeller boss is either pre-machined to a scraping tolerance or is finishmachined.

- When the shaft hole is finish machined by WPNL, a blue fit test on the propeller shaft hole hasbeen carried out. A classification surveyor has witnessed the result of this test.

- In most cases the yard has to perform the blue fit test for a local classification surveyor, evenwhen WPNL already obtained approval of the fit.

- The contract indicates whether the propeller cone is delivered pre- or finish machined.

1.1.3 Preparations


• Prepare required tools and blue fit paste.

• Sufficient space.

• Cleaning material.

1.1.4 Procedure; Fitting of propeller by means of scraping

The shaft hole in the boss is pre-machined to a specified scraping tolerance on the inner diameter.For an accurate fit between propeller and shaft cone an additional scraping shall be carried out.The result of scraping has to be checked by means a blue fit test.

- In order to reduce the possibility of a premature oil leak it is important to avoid linear groovesto the extreme forward and aft ends of the propeller bore. See drawing “Propeller boss”.

- The effect of the scraping shall be regularly checked, by means of a template, cone or shaft fit.

1.1.5 Blue fit test

A classification representative shall witness and approve the results of the blue fit test.

The propeller is not pushed up the shaft cone. For the purpose of contact area determination onlythe shaft shall be put into the propeller shaft hole.

When the blue fit test is carried out in a machine shop, it is advised to position the propeller(exactly) horizontal on the floor. The shaft is lifted in vertical position above the propeller shaft hole.

1. Clean the shaft or gauge and the propeller cone hole with solvent cleaner.

2. Apply a thin layer of blue fit paste on the shaft or gauge cone.

3. Gently insert the shaft or gauge cone into the propeller. Do not force the shaft or gauge. Onlythe own shaft or gauge weight is applied during the fit test. If the propeller has to be fitted inhorizontal position (for instance behind the ship), the propeller must be pushed onto the shaftusing the hydraulic nut. Use in this case the start point load as an alternative for the shaftweight that is used in case of vertical fitting.

4. Protect the propeller blades to prevent damaging.When the cone is completely in the shaft hole, hit one of the propeller blades with a softhammer. These vibrations will lead to a reliable marking.

5. Check the markings at the propeller cone hole.The fit is acceptable when markings are obtained over a 50 mm band at the extreme forwardand aft ends of the propeller cone and on at least 70% of the total cone surface.

6. In case the fit is not acceptable, scrape the propeller cone surface where required.

7. Continue with point 1 and repeat this procedure until satisfactory result.

8. Check the linear grooves to the extreme forward and aft ends of the propeller bore.

9. After approval, clean all cone surfaces and protect all cones against any dirt and damage.
