Sandblast outdrive parts
|
Lower unit is disassembled, and placed into the sandblast area
|
|
inside gearcase and out
|
The outside and inside of the housing is sandblasted, removing all rust and corrosion
|
|
Sterndrive rebuild parts
|
New parts are installed, with the exception of the bearing carrier and bearing retainers which are sandblasted and
primed. For repair jobs, if parts removed from customer unit can be re-used, they are sandblasted. Some are primed such
as the bearing carrier.

New prop shaft installed
|
For replacement rebuilt lower units, a new propeller shaft (GLM P/N 22414, 1-3/16") is installed. For
customer units, a dial indicator is used to determine if the propeller shaft is out of round (bent). This would not be visible
to the eye when turning so the tool is required. The threshold we use to determine if it needs to be replaced is .004"
out of round. Any more than that, and continued use of the bent unit would damage the oil seals and allow for water to enter
the gear case and oil to leak out.

Forward gear set
|
For rebuilt units, a new forward gear and pinion are installed. For customer units, the forward and pinion are
inspected for any chips or cracks on the teeth - or excessive pitting that would effect the integrity of the tooth on the
gear. If found, a new forward/pinion set is installed.

forward bearing retainer
|
The forward bearing housing assembly is installed (GLM P/N 27700, replaces 389455). This has the bearing pre-installed into
the housing.
|
|
Clutch dog
|
A new clutch dog is installed (GLM P/N 22625, replaces 337774). For customer repair jobs, the teeth (corners)
on the clutch are inspected - if there are signs of wear, in which the edges are beginning to or have rounded out, a new clutch
is installed. Re-using a worn clutch would continue to cause problems with shifting, possibly loss of forward and reverse
or shift cable damage.
|
|
Drive shaft
|
The vertical drive shaft is installed. For customer lower units, the unit is inspected for excessive wear or
damage to the threaded area. In many instances, the boat parts can be repaired using a lathe. Shaft must be replaced if it
is not repairable.
