5.3. Disassembly of the Altimeter
Important
The steps outlined here will expose sensitive electronic equipment and so
appropriate steps should be taken to prevent any static discharge occurring
which may harm the equipment.
Service tools required
• Clean absorbent wipes
• Silicon grease MS-111 lubricant (or equivalent)
Disassembly
1. First rinse the altimeter and connector in fresh water and dry with absorbent wipes.
2. Grasp the connector endcap firmly in one hand and the body tube in the other.
3. Gently unscrew the body tube.
4. The electronics block will then slide out of the housing attached to the connector endcap.
5. The transducer may be unscrewed from the opposite end of the body tube in the same
way.
Re-assembly
1. Carefully clean all parts and check for damage.
2. Inspect o-ring seals and replace if necessary.
3. Check that the earth loop on the electronics block is secure and sprung so that it will
contact the inside face of the body tube when it is fitted.
4. Lightly grease the o-rings, o-ring grooves and mating surfaces.
5. First screw on the transducer to the body tube until the thread shoulder faces contact.
6. Carefully insert the electronics block into the body tube and screw on the connector
endcap.
7. Ensure that the individual parts are aligned and mating correctly.
Caution
The threads of the altimeter should be made up and broken out by hand, or by
using light pressure on a strap wrench. The application of additional force may
indicate and result in damage to the unit.
