Abstract
A gearcase assembly for a marine drive has a torpedo housing having a cavity for containing lubricant, a passage configured for filling and draining of the lubricant to and from the cavity, a first bore and a second bore which connect the passage to opposite sides of the cavity, respectively, and a combination filling/draining device having a filling configuration in which inflow of the lubricant to the cavity via the first bore is restricted, a draining configuration in which outflow of the lubricant from the cavity via the first bore is comparatively less restricted, and a closed configuration in which outflow of the lubricant from the cavity via the passage is prevented.
Claims20
A gearcase assembly for a marine drive, the gearcase assembly comprising:
- a gearcase housing having a cavity for containing lubricant;
- a passage providing an inlet to the cavity from outside the marine drive, the passage configured for filling and draining of the lubricant to and from the marine drive;
- and
- a combination filling/draining device having alternate configurations including a filling configuration in which inflow of the lubricant to the cavity via the inlet is restricted, a draining configuration in which outflow of the lubricant from the cavity via the inlet is comparatively less restricted, and a closed configuration in which outflow of the lubricant from the cavity via the inlet is prevented.
A gearcase assembly for a marine drive, the gearcase assembly comprising:
- a gearcase housing having a cavity for containing lubricant;
- a passage configured for filling and draining of the lubricant to and from the cavity via an inlet;
- a first bore and a second bore which each connect the passage to the cavity;
- and
- a combination filling/draining device having a filling configuration in which inflow of the lubricant to the cavity via the first bore is restricted, and a draining configuration in which outflow of the lubricant from the cavity via the first bore is comparatively less restricted,
- wherein the combination filling/draining device prevents inflow of the lubricant to the cavity via the first bore and wherein the combination filling/draining device permits outflow of the lubricant from the cavity via the first bore.
A gearcase assembly for a marine drive, the gearcase assembly comprising:
- a gearcase housing having a cavity for containing lubricant;
- a passage configured for filling and draining of the lubricant to and from the cavity;
- a first bore and a second bore which each connect the passage to the cavity;
- and
- a combination filling/draining device having a filling configuration in which inflow of the lubricant to the cavity via the first bore is restricted, and a draining configuration in which outflow of the lubricant from the cavity via the first bore is comparatively less restricted,
- wherein the combination filling/draining device includes a fitting disposed in the passage in the filling configuration and wherein the fitting is removed from the passage in the draining configuration.

- a passage configured for filling and draining of the lubricant to and from the cavity;
- a first bore and a second bore which connect the passage to opposite sides of the cavity;
- respectively;
- and
- a combination filling/draining device comprising:
- a filling configuration in which inflow of the lubricant to the cavity via the first bore is restricted,
- a draining configuration in which outflow of the lubricant from the cavity via the first bore is comparatively less restricted, and
- a closed configuration in which outflow of the lubricant from the cavity via the passage is prevented.
