The Owner’s Manual 595-055-E recommends that the Motor/Gearbox is removed and returned to Seldén
at 5 yearly intervals. This rarely happens.
For Owners, there are two options:
1. Return the motor/gearbox to SML as suggested. Repairs will use the relevant kits, and have the
necessary labour time added.
2. Purchase the relevant kit/s, and have a knowledgeable mechanic carry out the service. This is a
specialist task, and not a service offered by Seldén representatives.
Kits are available for replacement seals and bearings

The core of the gearbox is lubricated with marine "non-water absorbing" type grease. This surrounds the
worm wheel, worm shaft and associated bearings. Oil is not required**.
(** Earlier model gearboxes were oil lubricated. The only regular attention is to check the oil level. Remove
the white plastic screw. If there is a slight weep of oil, the oil level should be fine. If not, slowly top up with
OEP90 gear oil. The total capacity is 0.5L, so it should only need a little extra to reach the correct level.)
The port side gears and belt, inside the oval casing, are not lubricated.
To fully service the electric motor/gearbox, it should be removed from the mast.
After removal, the sequence is :Remove the oval side cover, and withdraw the motor and 540-410 driveshaft.
Remove the Worm Retainer (see Page #1). Angle the Worm Shaft aft, and remove the vertical shaft +
wormwheel (see Page #2). Remove the Worm Shaft.
Replace bearings as necessary, and all seals.
To only replace the horizontal shaft seals & bearings , the motor/gearbox casting does not need to be
removed from the mast.
The sequence is:1. Remove the oval outer cover. This also withdraws the electric motor, which might be restrained by its
cables. If necessary, push the cables from below deck to introduce slack behind the motor.
2. Remove the large pulley, shaft 540-410, shaft key 301-079, spring & drive shaft 530-405. You may need
to push from the star socket end to force them out. The plain bush in the worm retainer will also slide out
with the drive shaft.
3. Remove the 6 hex socket screws and remove the worm retainer. If it doesn't move easily, you can push
out from the star socket end. As you push, you must also turn the worm shaft, as it is engaged with the
horizontal worm gear. This is shown in dotted outline on page #2.
4. Having dislodged the worm retainer, remove it. This will allow the worm shaft to move off centre.
5. Continue to unscrew / remove the worm shaft. The starboard 540-414 roller bearing will stay on the
shaft, and withdraw from it's recess.
6. When all is cleared out, you should be able to replace the 530-450 oil seal.
By this stage you will be very aware that the gearbox is grease lubricated ~ not oil
Gearboxes of an earlier production type used oil for lubrication. This should be replaced with a suitable
“non-water absorbing “ grease.
Before re-assembly, check the worm retainer plate seal groove edges. If they are sharp, they can be
rounded slightly. During re-assembly, take great care not to damage the “O” seal.

The seal is a continuous cord type, and must be cut to length so that the complete recess is
filled.
When removing the cover, the upper gearwheel & shaft, plus the lower gearwheel, shaft and
motor all move.
If oil is present in the cavity containing the gears & motor, it is likely that the seal 530-451 (see
page #1 ) is leaking.
