Lambretta Cylinder stud kit (long studs, extended nuts, thick washers) MB

MRB0328K

This is a set of MB 4 cylinder head studs, 4 thick cylinder head washers, three special cylinder head nuts and one extended cylinder head nut for the cowling.

The studs are longer than normal and have more thread to suit cylinders commonly used with cylinder packing plates and head gaskets and the threads are longer to suit shortened cylinders.

The studs are thicker in diameter so they locate the cylinder, giving no rock so if you have the transfer ports opened out the ports stay inline. Some cylinders can be tight using these studs - cure is to drill out the stud holes in the cylinder to 8.5-9mm.

Fit the short threaded end into the casing, the longer threaded end lets you fit shortened, standard, extended and cylinders using packing plates.

There is nothing better on the market, Mark Broadhurst has designed and tested them over many years.

These studs do not stretch and if assembled correctly the head nuts stay tight.

Torque the nuts down to 18 - 20 lbs ft.

Re-tighten the nuts at 500 - 1000 miles from a new rebuild.
