Item Details- MerCruiser Sterndrive Alpha One Lower Unit Complete Gearset 43-96084A4 (Pinion, Forward, Reverse) & Bearing Carrier
- Used in MerCruiser MC-1, #1, "R Drive" lower units 1970-1982 (If your driveshaft HAS A PRELOAD PIN then these are the CORRECT parts, if yours does NOT have a preload pin (1983-1990 drives), then these are NOT the correct gears)
- The time period 1970-1982 should be the time period that covers when the drives still had the preload pin, but the easiest way to identify what type of gears is whether or not there is a preload pin, and by physically looking at the gears you can see they have a different rotation.
- Gearcase Must have Preload pin and Serial Number 3469428 & Up
- Also, the gears used from 1970-1977 were different than this set here, but as long as you are replacing the entire set you can interchange both ways. The set presented here is the updates superseded version.
- Pinion Gear: 43-826192
- Forward Gear: 43-96084
- Reverse Gear: 43-92320
- Used in MerCruiser MC-1, #1, "R Drive" lower units 1970-1982 (If your driveshaft HAS A PRELOAD PIN then these are the CORRECT parts, if yours does NOT have a preload pin (1983-1990 drives), then these are NOT the correct gears)
- Used but in great shape!
- This set should be good to go, but you will need to please inspect the ball bearing to your liking before installation. It may need to be replaced and these can be obtained rather affordably easily if needed.
