X-Dimension engine maint log

Feb-May 2013

An extensive engine maintenance program was carried out to address:

Lube Oil leaks:
Both the front and rear crankshaft oil seals were replaced. The timing cover gasket was replaced as well. As of 6-May-2013 there is still a slight oil leak from the timing cover.

Fuel Oil leaks:
The lift pump was replaced. The O-rings in the injector pump sealing the throttle and cut-off shafts were replaced. The cut-off lever was reversed so that the T-handle is now pulled to stop the engine.

Filters:
The lube oil filter was changed from a cartridge filter to a spin-on filter. The new spin-on mount needed the fabrication of a 2-inch aluminum spacer (Thanks Keith W.!). The primary fuel oil filter was mover from the bottom of the stbd cockpit locker to the port side of the engine compartment (under the stairs). The primary fuel filter element was changed from a 30-micron filter to a 10-micron filter (the same size as the secondary fuel filter mounted on the engine) so that a clogged filter will be easy to change (assuming the first filter will become clogged first). The secondary fuel filter element was replaced.

Also:

• The Jabsco raw water pump was rebuilt (new lip seals), and the impeller replaced.
• Intake and exhaust valves adjusted.
• The copper tube assembly of the Bowman heat exchanger was flushed with Simple Green (no real build-up of scale noted). The rubber boots were replaced.
• Engine idle and anti-stall body adjusted.
• Prop aligned
• Throttle and transmission shift cables replaced.
• Various hoses replaced.
