Jumping and hacking gears, loosening brake drums, quick worn gear wheels can all be caused by a worn or defect drive shaft.
Bad maintenance, high mileage or extreme tuning can support irregular wear. With this spare part you can bring your Vespa back into top condition for clean gear shifts.
This spare part has hardened flanks for accurate cruciform actuation. Designed for the gears and cruciform of the late p-range.
The bearings on the drive side and the shift side should be renewed for a perfect result and reliability.
Check the cruciform for wear as well and renew.
Gear box shims to set up the gearbox accurately are available separately.
