The Lucas MO1 replica by BT-H Magnetos
Ltd MD1R extra fitting instructions The
fitting of this unit is similar to the fitting of our PM platform magneto but
the following should be noted and checked relating to the fitting of your
dynamo. 1. Before fitting, push the
dynamo onto the top of the magneto and engage the gears. Tighten the strap
supplied and make sure there is a little clearance / backlash between the gears
by rocking the shaft back and forth. Check all the way round. The gear is new on
the unit and will bed in after a few miles, however a tight gear will put
pressure on the gears and bearings. 2.
There are two types of fittings for the unit. One is by strap as on Royal
Enfields, BSA singles, etc. The magneto will have 4 x 5/16” stainless pegs in
the base to locate in the engine platform. The other is bolted from the
base by 4 x 3/8 BSW holes as on Ariel singles, Nortons, etc. The strap type can put
pressure on the dynamo when the engine strap is tightened and make the gears
tight causing them to whine. If this happens you may need to insert shim under
the dynamo to create a little backlash in the gears. 3.
Make sure the fibre gear and steel gear are well greased. This can be
done easily through the dynamo hole rather than by removing the gear cover of the magneto.
This is sealed
on assembly and the screws
have "nut lock" grade Loctite on them. 4.
You can run a rev counter off the pinion nut as per original if the bike
was fitted with one 5.
The unit will also run a second spark plug if the bike has a twin plug
head. This can be retro fitted at a small cost without removing the
magneto. Please contact us for more detail |
