LUBRICANTS

We receive a number of inquiries regarding the effects of adding any of the proprietary Molybdenum Disulphide based additives compounds to the lubricants of our various mechanical units, and perhaps more to the point, we are asked frequently if there is any need to use such additives.
If conventional lubricants are perfectly satisfactory for the lubrication of any given bearing, there is no purpose to be served in adding anything.

Bearings lubricated in accordance with our standard recommendations used under normal operating conditions and running within their defined capacity, can obviously derive no benefit from the addition of MoS2 to the lubricant

There are certain applications on our vehicles where the addition of such additives can lead to dissatisfaction. The makers of the overdrive unit fitted to Rootes Group vehicles have stated that MoS2 additive should not be used in their units and we also feel there is danger of the synchromesh action being affected in our gearboxes if the normal lubricants are interfered with.

To summarise, there is no need to use these additives under normal conditions and, in the case of overdrives and gearboxes, they are not recommended.

Kindly bring the above to the attention of all concerned.

Very truly yours,

ROOTES MOTORS INCORPORATED

SUBJECT: BRAKING SYSTEM FLUIDS

Our overseas associates advise us that since the Automotive Products Co. Ltd. has announced that a new brake and clutch hydraulic fluid is being made available this will supersede the present fluid used in Lockheed hydraulic components.

This new fluid is known as LOCKHEED SUPER HEAVY DUTY FLUID and meets the requirements of the International SAE Specification 70 R3. Thus the fluid is suitable for use in Lockheed drum brake systems and the Sunbeam Rapier disc/drum system as well as hydraulic clutch units.

Effective immediately, therefore, the recommended hydraulic fluid for all models of our Light Car and Light Commercial Vehicle range (which are equipped with Lockheed brakes) is Lockheed Super Heavy Duty Brake Fluid (SAE Spec. 70 R3).

Kindly bring the above to the attention of all Service personnel at your location.

SUBJECT: DISC BRAKES SUNBEAM ALPINE SERIES I & II

Where complaints are received in respect of “squeal” on the disc brakes fitted to the front wheels of the above model, this can be overcome by fitting special anti-squeal shims.

The shims, of which four per car are required, can be obtained through the normal Parts channels against Part Number 1206222.

To fit, proceed as follows:

Jack up the front of the car and remove the road wheels.

Remove the retaining pins and clips used to secure the brake pads in the calipers.

Clean off any road dirt or grit found on the pad backing plate. Insert the shims supplied between the front of each piston and the rear of each brake pad. When fitted, the semicircular cut-out on the shim should be facing downwards, away from the bleed screw, and the tongues should be facing outwards. (See illustration).

Refit the retaining pins and clips. Refit the road wheels and lower the jack.

These shims have been fitted in Production from Chassis Number B.9103936.

Kindly bring the foregoing to the attention of all Service personnel at your location.
