UK made straight cut A PLUS gear kit includes 1ST, 2nd, 3rd gear, 1st motion shaft, reverse gear and laygear for Rod change. Please order genuine C-22A1741 baulk rings when fitting this gear kit or if using your own please make sure they do not rock on the gear. These are the original ratio and tooth counts as used by ST Abingdon but from new tooling and teeth profiles which are shot peened for efficiency and durability with less noise, which also does not absorb so much power from the engine. These gears are banded with 2 rings for identification. Laygear still uses 3 bearings on layshaft.

Do not mix and match with other gears that have same teeth counts unless they have the same 2 identification bands.

For rod change only with 18mm mainshaft. For 4 sync remote see C-AJJ4014. For rod change with 14mm mainshaft see C-STN76. Always select 1st and 4th gears plus reverse when locking up gearbox for dismantling and assembly.
