3/4" to 1" inch w/Step Key Gas Engine Crank Shaft Sleeve Adapter for Predator
This 3/4" to 1" inch crank shaft sleeve adapter with a step key is designed to fit gas engines, allowing a 1" shaft to be adapted down to 3/4" for use with pulleys, couplings, or other drive components.
Overview
This gas engine crank shaft sleeve adapter lets you mount a 3/4" bore accessory onto a 1" engine shaft, with the step key locking it in place. It is commonly used on horizontal-shaft engines for go-karts, generators, water pumps, and other power equipment applications.
Built For Performance
- Machined steel construction for durable, long-term service on gas engines
- Step key design provides a secure, non-slip connection between the shaft and adapter
- Precision-bored 3/4" inner diameter fits standard 3/4" keyed pulleys and hubs
- 1" outer bore matches common gas engine crank shafts, including Predator models
- Simple slip-on installation with no special tools required
Fits These Machines
- for Predator 212cc and similar horizontal-shaft gas engines
On-The-Job Use
- Adapting a go-kart torque converter to a 1" engine shaft
- Mounting a water pump or generator head with a 3/4" bore
- Connecting a jackshaft or clutch assembly to your engine

Good To Know
Q: Will this adapter fit a standard 3/4" keyed pulley? A: Yes, the 3/4" inner bore is keyed and accepts a standard 3/4" shaft pulley or hub with a 3/16" keyway.
Q: Is this adapter reversible for use on a 3/4" shaft? A: No, this adapter is specifically machined to step down from a 1" shaft to a 3/4" bore, not the reverse.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
