🔌 Function

Sets the reduction between the drive's input and output, the matched pinion and crown wheel turning engine speed into propeller shaft speed at the marked ratio.

⚠️ Common Signs of Failure

• Whine or growl from the drive that changes with load rather than with engine speed
• Clunk when taking up drive or changing direction
• Metallic glitter or flakes in the drained drive oil
• Teeth found pitted, chipped or with the hardened surface breaking away
• Contact pattern found off the centre of the tooth on strip-down

🛠️ Service Notes

• Order by ratio - the seven sets here fall inside 370 grams of one another, so weight separates nothing
• Supplied as a matched pinion and crown wheel; fit them as a pair and never mix halves from different sets
• Renew the bearings, shims and seals with the set, and set backlash and contact pattern on assembly
