Vespa primary repair kit - springs, plates and rivets for rear damping

In the primary gear of many Vespa engines, there is a spring assembly under the cover plate that absorbs drive shocks - a mechanical "buffer" between the crankshaft and gearbox. This primary repair kit provides the right components to repair this back damping: Springs, cover plates/separating washers and rivets. The highlight: It is an inexpensive kit for a low-cost repair if the primary itself is still in good order and you don't want to replace a complete primary gear straight away.

When the damper springs in the primary gear get tired or break, the power transmission becomes rough: when engaging a gear or changing load, there is often a noticeable jerk or a hard "clonk". This is a typical indication that the damping is no longer working properly. With a fresh repair kit, the primary can be calmed down again - and the mechanical load on the periphery is reduced.

Ideal for overhauling standard and lightly tuned engines where a reliable, economical solution is required.

Primary gear back damping Inexpensive overhaul 12 springs Ø 106 mm Øi 58 mm With rivets

Reinforced version (200 cc) - also suitable for 80-150 cc

The kit corresponds to the reinforced version of the 200 cc models with double springs. This version can also be installed in engines that have a single suspension in the primary gear as standard (typically 80-150 cc), making the kit a practical option if you want a little more reserve in the rear damping during an overhaul - without having to invest in a completely new primary.

Conclusion

Replacing the rear damping in the primary gear is a must for many engines if they are being overhauled anyway. Worn or broken springs not only make for a rough ride, they also increase the load peaks in the drivetrain. With this cost-effective primary repair kit, you can restore the damping - ideal for standardand lightly tuned setups. Thanks to the reinforced 200 cc version with double springs, the kit is also a sensible option, even if your engine was originally only equipped with single springs (80-150 cc).
