1. Drive Shafts and Coupling Flanges

Between the jet and the engine there is always an intermediate shaft which transmits the

power from the engine to the jet propulsion unit’s main shaft. There are various types of

shafts. Normally, the shaft has been chosen and installed by the boat’s manufacturer.

1.1. Joint Types

A constant velocity shaft is a cardan shaft between the engine and the jet, which allows

angle deviations. The joints are based on balls rolling on a spherical surface. This shaft

type enables vibration-free running even if the joint angles at different ends of the shaft

deviate from each other.

1.1.1. Constant Velocity Shaft

Detachment, Repair and Installation

At the engine side the constant velocity shaft is attached to the ywheel, to a coupling

ange installed by the engine manufacturer or to the gearbox. There can be an adapter

ange between the joint and the engine, with which the engine and shaft hole spacings

are tted with each other.

There can also be an adapter ange between the jet’s coupling ange and the joint.

Open the joint fastening screws

at the jet side and leave the pos-

sible adapter attached to the

coupling ange. The bolts can

be hex or socket screws (gure

1.1.1-1).

Open the joint fastening screws at the engine side and leave the possible adapter at-

tached to the ywheel.

The rubber covers and the whole end of the joint are removable parts of the constant

velocity shaft.

If the rubber cover of the joint is broken, lubricating grease comes out and the danger is

that the whole joint may break down. A broken rubber must be replaced immediately.

Follow the manufacturer’s instructions in repair and installation.

Figure 1.1.1-1

Repair Manual 1 6

Version 1.00

The rubber joint is an elastic rubber element on the intermediate shaft between the en-

gine and the jet. The rubber element dampens the vibrations and sudden torsional loads

that are transmitted from the engine to the boat’s hull, and allows some angle deviation.

An intermediate shaft equipped with rubber joints is installed similarly to a constant

velocity shaft. Because the shaft, engine and jet propulsion unit anges are not always

compatible, it is usually necessary to use adapter anges.

There are various types of intermediate shafts equipped with a rubber joint. The

manufacturer’s instructions must be followed in repair and installation.

1.1.2. Rubber Joint

1.1.3. Cardan Shaft

The cardan shaft has been pivoted with spider bearings. The joint angles at different

ends must be of equal size to attain vibrationless and durable running.

The cardan shaft has been installed similarly to the constant velocity shaft. Adapter an-

ges are used sometimes because the shaft, engine and jet propulsion unit anges are not

always compatible.

1.2. Tightening the Fastening Screws

The following information will serve as general instructions:

Always tighten the fastening screws of the coupling anges ngertight rst and after

that in a crosswise sequence gradually until they are at the correct torque. This ensures

that the joint is attached evenly to the coupling ange.

However, check with the manufacturer that possible instructions given separately by the

manufacturer are followed in tightening.

Use thread locking compound to tighten the bolts. Observe the manufacturer’s instruc-

tions on using a thread locking compound.

1.3. Balance

The balance and correct installation of the intermediate shaft on the joints at different

ends is imperative to a functioning whole. Unbalance of the intermediate shaft, anges

that have been tightened or attached incorrectly cause the equipment to break down very

quickly.

1.4. Coupling Flanges

Different kind of coupling anges are installed to the jet’s main shaft depending on the

type of the intermediate shaft and engine power. Commonest of these are SAE 1310,

VNA 10.

If necessary, there is an adapter between the coupling ange and the transmission shaft,

which enables fastening.

Removing:

The coupling ange is tightened on the conical shaft end with an M16 nut. Unscrew the

nut (gure 1.4.-1) and pull the ange off the cone with a puller (gure 1.4-2). There is

a spacer under the fastening nut, which presses the shaft on the coupling ange. Never

install the coupling ange without the spacer. Remove the wedge from the groove (-

gure 1.4-3).

Figure 1.4-1

Figure 1.4-2

Repair Manual 1 8

Version 1.00

The shaft can be stopped from rotating with a bolt that is pushed

through the fastening screw hole against the surface of the bearing

housing. See gure 1.4-1.

Different models have different types of bearing housing structure. This does not affect

the fastening of the coupling ange.

2. Bearing and Main Shaft

2.1.1. Disassembly

2.1. Front Bearing

2.1.1.1 Jet-160

The bearing housing is xed in the casting. Only the support bearing housing is remova-

ble.

Before the shaft can be disassembled, the reversing deector, the steering nozzle, the

stator (see sections 4-6), and the impeller (see section 3) must be removed from the rear

of the jet. The boat must be out of the water.

Remove the coupling ange as described in section 1.4.

Open the fastening screws of the support bearing housing (6 pcs) as in gure 2.1.1.1-1

and remove the support bearing housing (gure 2.1.1.1-2).

Version 1.00 Version 1.00

The shaft protrudes into the en-

gine room with the bearings. The

t may be tight, but when pushed

from the outside, enough force is

produced to remove the shaft (gu-

re 2.1.1.1-3).

There are still two shaft seals in

the bearing housing. They can be

removed with for example a sc-

rewdriver.

Figure 2.1.1.1-3

The bearing (gure 2.1.1.1-4) consists of a thrust bearing that receives the pure axial

force (A) and an angular ball bearing that carries radial loads (C). The plate (B) between

the bearings transmits thrust from the thrust bearing to the outer race of the angular ball

bearing.

The safety ring (D) prevents the bearings from sliding off the shaft. The actual forces

are received with the shoulder in the support bearing housing, which presses on the ou-

ter race of the bearing.

Figure 2.1.1.1-4

Repair Manual 1 10

Version 1.00

To remove the bearings, rst

remove the safety ring (A) and

then push the bearings off the

shaft (B) (gure 2.1.1.1-5).

Figure 2.1.1.1-5

Figure 2.1.1.1-6

There is a needle bearing in the

support bearing housing, which

carries radial forces. There is a

shaft seal behind the bearing,

and a safety ring in front of it,

which stops the bearing from

sliding out from the bearing hou-

sing.

To remove the bearing, rst re-

move the safety ring (gure

2.1.1.1-6) and then push the seal

and the bearing from the seal

side at the same time.
