HPS{Horace Percy Smith - Experimental Factory Mgr}/RH.{R. Hollingworth}1/VS.{J. Vickers}3.6.37.

Oil Cooler LOP.E.86801. LeC.4871.

Special strengthened cooler supplied by Rm{William Robotham - Chief Engineer}/Std.
Condition good - no sign of leaks or breakage.

Spring Drive LOP.E.86976.

The friction faces were in good condition and were free from tarnish or corrosion. The initial load required to move the damper was high, being 35 lbs. at 17 1/2" radius. Immediately movement started, however, the load dropped sharply, 10 lbs. being sufficient to maintain movement.

Ignition Distributors LOP.D.75167. LeC.4950.

The main spindle and bearings were in good condition. The centre automatic advance spindles had been running dry and were rusty. The governor arms were worn badly in the centre holes, which accounted for some lost movement in the automatic advance, and wear had also occurred on the ball-pins of these arms and the holes in the centre spindles. These governors seem to be a poor job as regards material and finish, and, as several complaints have been made about lost movement, we suggest that this should receive attention.

Carburetter Air Silencer LOP.E.88088. LeC.5000.

The filter element (Burgess) appeared to have been effective as it was quite clean on the inside, though dirty on the outside.

As this silencer had been used in combination with the four port head system, there was no rear stay fitted. The rivets at the front were loose. We suggest additional rivets with a view to deleting stay as on this test.

Controls.

A considerable amount of wear had taken place throughout the controls and could be mainly attributed to excessive wear in the spherical bearings, the majority of the wear occurring on the bronze spheres rather than on the steel seatings. This matter requires investigation.
