MKI Ignition Coil Bracket

Contributor: F. Navest

Originally the LUCAS ignition coil was located very close to the distributor on a bracket that was attached to the engine support.  This bracket was exclusively applied for the Mk1 MGB, 3 synchro cars built form ’62 till October 1967.  This bracket was removed during the design of  the Mk2 to allow future   simplification of maintenance.

Early MGB Lucas Sparkplug caps, cables

The original LUCAS 78106A sparkplug caps were original wear on 3 synchro cars, (i.e. during the production of the 18GA & 18 GB engines). They do, on the other hand, cause radio interference that was difficult to suppress properly. The technology involved with these plugs and cables was outclassed.

The state of art technology in 1967 meant that the copper core cables had to be replaced by silicone cables, which have a degree of  internal resistance that surpasses the interference to radio and TV equipment.

 

These early 60’s  Solid copper core High Tension cables in combination with LUCAS side entry distributor caps and LUCAS sparkplug caps last forever, however. I am not sure how long the Ignition Lead Spacer and yellow identity markers were maintained. I have the impression that the Spacer as discontinued in 1967, whereas the markers were probably continued till 1969.

Early Spare Wheel Clamps

Contributor: F. Navest

In order to secure a spare wheel to the boot floor of the MGB, various design clamps have been designed and applied.

 

Wire wheels:

The original wire wheel clamp has only been supplied for ’62 cars upto chassis GHN3 / 4514 in December 1962.  It had a cylindrical head, sticking well above the spare wheel. This protruding area caused damage to the luggage.

The later design clamp is a simpler design that would cause less damage to luggage.  It has a flat bar across the top protruding to a lesser degree above the spare wheel.

Standard pierced steel disc wheels:

The spare wheel clamp issued for the standard steel wheels was retained right-up to the introduction of the Rostyle wheels in 1969.
