The gear sets for the 5NHP Road Locomotive are available as complete sets, gear cut and with the two keyways cut in the final drive pinion but not the splines on the crankshaft pinions. All gears are steel, in EN8.
The three speed crank shaft gear cluster on the Road Locomotive pinions are identical to the Devonshire engine but the final drives are noticeably larger on the RL. The Devonshire final drive is 19.25” OD whereas the Road Locomotive is 23” OD, both are 1.375” thick.
By ordering multiple gear sets the price is believed to be highly competitive. Both the 3 speed Devonshire and 3 speed Road Locomotive gear sets are normally stock items.
Each gear set comprises:
3 speed change pinions, note splines now not cut
3 seed gear rings
2 final drive pinions, keyways cut
2 final drive gear rings (larger rings and bigger teeth than Devonshire engine).
Road Locomotive gear set £2,140
Road LocomotiveWorm and Wheel £195
