Preparation condition before push-up6.1 The propeller shaft were a niced match for the propeller have finished machining & matching, and submit it to owner and surveyor for approved.6.2 Bolts hole of the big end propeller have bore use to mounting pressplate.6.3 To make sure the working safely and conveniently, there is an working platform with the railing、ladders etc to be built nearby the stern and from basic line abt. 3m.6.4 Lifting eyes for propeller to be checked and welded at proper position on hull structure.6.5 Lifting devices and fittings have been checked and prepaied etc.6.6 There is no any job casing the strong vibration of concerned hull structure.7. Application7.1 After carefully cleaning all touching surface and oil passages inside propeller hub and shaft by using compressed air,the touching surface to be painted with lubrication oil which is the same as hydraulic oil. 7.2 Carefully checked the propeller shaft and hydraulic nut screw thread,At the coating MoS2 on the screw thread surface after ensure cleaning .7.3 Keeping the propeller and shaft at the same abbient condition for abt. Two(2) hours in order to make the both parts with nearest temperature as far as possible.7.4 Fore seal device with the gasket and after seal device of sterntube onto the shaft and temporarily fixed , and submit it to owner and surveyor for approved.7.5 Lifting and putting the propeller onto the taper part of propeller shaft until the fore end of propeller reaches at the position with special mark on the shaft,which is made after finally tooling the touching surface between the propeller hub and the taper part of shaft in workshop.7.6 When one bolt hole of the shafting is upward（TOP）,we should be sure that one blades of propeller is also upward(TOP).7.7 Carefully cleaning the hydraulic nut and turning it onto the screw-thread part of the propeller shaft properly.Connecting the hydraulic system according to Fig.2 untill vent out the air in full hydraulic system by operating the manual pump A,B and after that screwing the plugs on the propeller hub and hydraulic nut. arranging the three(3) sets of micrometer according Fig.2.7.8 Confirmation of the Zero(0) point (detail see Fig.2)7.8.1 Owing to propeller and propeller shaft is to be keyless fitting,in order to procure nicety axis push-up and thrust force of the propeller, ensure greating installtion on its position,so must be confirmation of the Zero(0) point at first.7.8.2 Open valve A,close valve B,operating the manual pump a connected with hydraulic nut,adjusting the micrometers G1&G2 at the Zero(0) position respectively after oil pressure reaches 3Mpa,continue to opening the pump until the propeller to be pushed-up with 0.4mm(reading on micrometers G1&G2) and record the concerned oil pressure P1.Rrepeat the above operation by three times again and record the concerned oil pressure P2,P3,P4.One approximate line “CL” can be made out by using the above recorded datum and the cross point “Ls” of the line “CL” and axial line “S” is just the Zero(0) point total push-up distance.Detail see Fig.P-S curve.7.8.3 Open valve A and B,slowly pushing up the propeller by operating the two manual pumps properly until the required push-up distance “S” is obtained. Oil pressure of the manual pump A is no least than 4.74Mpa.A High pressure oil inlet of the expand hub;B High pressure oil inlet of the compaction.7.8.4 At all installation process,axes offset removed use by G3. 7.8.5 During this procedure,at least 10 groups of concerned oil pressure and pushed distance datum of to be recored in the below table,and drawing out Cw curve. Valid area of piston:1245.64cmPush-up distance（mm）pressure（Mpa）Axial pres.Radial pres.Environment temperature()：7.8.6 First releasing the oil pressure inside the propeller hub and thence keeping this condition until abt. 1015 mins passed,check the reading of the two micrometers G1&G2,the figures should be same as that before the hydraulic oil released.the hydraulic oil inside the hydraulic nut then can be released secondly,fitting the hydraulic nut and its safety devices according to the concerned drawings,complete the installation of propeller bonnet and fittings according to the relevant drawing.8 Push-up distance and thrust force8.1 Confirm actual push-up distance of the propeller According to location Environment temperature and Calculation for propeller keyless fitting(Drawing No.:SC4484-401-07JS).A.
