DISMANTLING AND ASSEMBLING OF PROPELLER BLADES AND HEAD
Before stopping the engine, set the propeller pitch at zero position.
When dismounting the propeller head cover, take care that the joint surface is not damaged. When
the joint bolts have been unscrewed, the cover can be loosened by turning the blades. When the
cover has been removed, the blades can be taken out by turning them around the sliding journal.
Thus, neither pull rod nor flange coupling have to be dismantled.
When blades and sliding blocks have been refitted, lubricate all moving parts with engine oil. Do
not fill up with grease until the cover has been mounted.
Prior to assembling the propeller head, see that the joint surface is completely free from dirt and
burrs, and prior to mounting the cover, clean the threaded holes of the propeller head carefully to
remove grease and dirt; otherwise the bolts may not be tightened sufficiently. Lock the joint bolts
by means of the stainless locking screws bored into the cover.
Then fill the propeller head with thin grease or sterntube oil SAE 140 as follows:
Place the head so that the filling hole is pointing straight downwards and the air relief hole straight
upwards. Fill grease into the bottom hole. The head is filled when grease is beginning to run from
the top hole. Finally, fill the joint bolt holes with tallow.
If the pull rod has been dismantled or when the pull rod is being mounted for the first time, proceed
as follows:
Screw the pull rod into the piston rod or the intermediate shaft sleeve by turning the propeller shaft.
Screw the pull rod home and then about 1/4 - 3/8 turn back so that the holes in the flange
couplings are facing each other.
