Lambretta cylinder stud kit (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.

if you are not doing a 100% factory restoration there is no other remade cylinder stud on the market better than these!

Great bit of kit. As I build my engine though, the only thing missing is some nice thick section spring washers to transfer the load from the flange of the nuts to the plain washers. What do you reckon MB? From Mark, they are designed not to use a spring washer as they get tired when heated up, nothing wrong with the thick plain washers these spread the load.

Good solid studs and bolts that hold the cylinder and head better than the originals

Steve G on 11 Oct 2012 asked "Hi,should i use any loctite on the ends that screw into the casing and is there a torque setting for the studs? (not the nuts) Cheers.....Steve"

MB Scooters Ltd replied: I always clean out the threads with a taper number one tap, and either use a fine smear of grease or loctite on the sides of the thread, I just nip them up, don't torque them into the casing, they just need to be in firm.

Sebastien M on 17 Sep 2009 asked "Hello mark, i've bought those studs from MRB, but don't know which threaded side goes inside the crankcase : the longest threaded side or the shortest threaded side. Shortest threaded side seems to be screwed completely to be fixed ( so no margin on the threads from the surface of the casing ) thus was wondering if there could be any risk to crack the casing then ? what do you recommend ? many thanks"

MB Scooters Ltd replied: The short thread goes in the casing. These are designed to be perfect fitting in most casings.

David on 26 Apr 2009 asked "I have a question about "Cylinder head stud kit (studs, extended nuts, thick washers)" Hello! Are thoose studs M8? How long are they? Regards David"

MB Scooters Ltd replied: The studs are 8mm and 163mm long.
