4) Use a screwdriver to gently pry out the seal cartridge.
5) Place the washer on top of the new seal cartridge and push it onto the shaft and into
the cartridge cavity.
6) Screw on the nut by hand until is tight against the seal, then back it off 2 turns.
7) Hold the nut with the wrench and tighten the propeller.
8) Replace the nozzle:
We recommend that you check for the presence of water in the oil bath every 10-20 hours
of usage. This interval should be on the shorter end if you use your VideoRay in deeper
water – in excess of 60 feet or 20 meters – for extended periods. If there is water in the
oil, the cartridge should be replaced within the next 10-20 hours.

8.8 MAIN HOUSING

8.8.1 OPENING VIDEORAY'S MAIN HOUSING

Note: To perform this operation, it is necessary to remove the Skid System first by un-
screwing the 4 skid retaining screws.
1) Prior to opening the main housing, it is important to ensure that VideoRay is clean and
dry, and that a clean, dry work area is available.
2) Remove the flotation block by removing its retaining screw.
3) Remove the main housing tie-rods by first loosening, then removing the tie-rod acorn
nuts and regular nuts at the rear that serve as jam nuts. The acorn nuts at the front are
permanently Loc-tited on and can be used to rotate the rod with a socket driver. Next,
pull the tie-rods from their guide holes in the front and rear main port retainers.
Remove the main port retaining rings.
Both the front and rear main port domes are sealed with O-rings and, while some resistance
may be encountered due to a slight internal vacuum, they can be removed by carefully
pulling them out of the main housing. The domes have tabs on them to facilitate dome
removal. You can use the tool kit nut driver or other blunt tool to apply pressure on these
tabs to remove the domes. Do not pry the domes off with a screwdriver as this can damage
the domes and the seal surface.
4) A hair dryer may be used to aid in removal of the domes by warming the VideoRay
housing and creating a positive interior pressure.
