Description
Ares Anti Reversal Latch GB-42
This is an Ares replacement anti-reversal latch, part code GB-42. The anti-reversal latch is a small but important gearbox part: it stops the gears from spinning backwards under spring pressure once the motor stops.
A worn or broken latch can let the gears spin backwards, which can damage gears and the motor, so replacing it promptly is wise. It is also a sensible spare for anyone who services Ares gearboxes.
How it works
After each shot the piston may be partly drawn back with the spring under tension. Without an anti-reversal latch, that tension would drive the gears backwards when the motor stops. The latch engages the teeth of the bevel gear and holds the gears in place until the motor turns again.
Decocking and safety
Because the latch holds the spring under tension, it must be released carefully before opening a gearbox. Always discharge the gearbox in a safe direction or release the latch carefully as described in your manual, and remove the battery first.
Fitting
The latch sits next to the bevel gear and is held by a small spring. Check the new part moves freely and springs back before closing the gearbox. Make sure the spring is properly seated, as a misplaced spring will stop the latch working.
