Overhaul
Fit the nozzle to the nozzle housing
Inspect the steering nozzle
Before re-assembly, the nozzle should be examined for any sign of damage. In the case of a severe jam-up of
the steering system, the nozzle arm may have become bent or cracked. If any cracks are found on the
underside of the steering arm or if there is any sign of bending, the nozzle must be replaced. No
straightening or welding repair is permitted.
Ensure that the nozzle housing is fitted to suit the correct nozzle trim required (nozzle straight or nozzle

up options). Refer to drawing: HJ21206000 Steering Assembly.
Fit the steering nozzle [16] into the steering housing [9], ensuring that the steering crank boss is

uppermost and the nozzle is aligned with the nozzle housing.
Rotate the nozzle to align the upper and lower bushes [10] with the upper and lower fixing points in the

nozzle housing.
Smear the stepped adjusting washers [14] with marine grease and fit to the bolts [12], ensuring that the

step in the washer faces inwards.
Thread the pivot sleeve [13] fully onto the bolt to retain stepped adjusting washer [14] in place.

Repeat the above to fit the second bolt [12].

Smear new o-rings [11] with an approved marine grease and fit to the seal groove in the pivot sleeves

[13].
Apply Loctite 222 to the threads of the bolt [12] and fit the upper attachment bolt [12] complete with

stepped adjusting washer [14] and pivot sleeve [13]. Screw the bolt in hand tight.
Apply Loctite 222 to the threads of the bolt [12] and fit the lower attachment bolt [12] complete with

stepped adjusting washer [14] and pivot sleeve [13]. Screw the bolt in hand tight.
Tighten both bolts [12] and torque load to 40Nm (30lbf ft).

Move the nozzle through its full arc of travel to ensure that there is no restriction.

Nozzle vertical end float adjustment
Check and ensure that the end float between the nozzle and the nozzle housing is between 0.1 to 0.4mm on
the bottom pivot.
Measure between the outer shoulder of the steering pivot flanged bush [10] and the inner face of the

stepped adjusting washer [14], at the bottom steering pivot point. This should measure between 0.1mm
to 0.4 mm.
Invert either one or both of the stepped adjusting washers [14] to achieve the measurement above.

The end float can be altered by inverting one or both of the stepped washers [14].
Apply Loctite 222 to the nozzle attachment bolts [12] and torque load to 40Nm (30lbf ft).

The nozzle and nozzle housing may now be refitted to the tailpipe of the jet unit.
