Luvax-Bijur car chassis "one shot" lubrication system.

Cover of the Luvax-Bijur instruction book
A number of quality cars built in the 1930s were equipped with the Luvax-Bijur centralised lubrication system. Rover, with its range of 10, 12, 14 and 16hp P2 cars was a well-known exponent of this labour-saving fitment, enabling the motorist to lubricate the key components of his/her vehicle's chassis simply, in one go. Riley, Lea Francis, Alvis, Rolls-Royce and Bentley also approved of its use on their cars. So long as it gets used regularly, there's no reason why the Luvax-Bijur system can't go on functioning into the future, although it's important to remember that if a car has sat idle for many years, there's a good chance that the plumbing for the oiling/greasing arrangements may clog up, leading to essential lubrication of suspension components and so on being missed.
Quite a few surviving cars have had the plumbing removed, or at least bypassed, reverting to grease nipples as fitted to most cars of the pre-war era. While this requires more time spent servicing a car, at least you can have confidence that the lubricant has reached the places it's needed. On the downside, it's a grubby old job, so having a central lubrication arrangement must have appealed to many buyers in the 1930s.
This original service instruction booklet dates to the 1930s. It describes how the various implementations of the system, as supplied by Lucas-CAV-Rotax, actually works, and how they might be maintained to ensure reliability in their operation. The choice of oil to use is also discussed.

Manual system.

The manual system - not dissimilar to the type found on various Rolls-Royce and Bentley cars of the era - is introduced in the following paragraph:
"All chassis bearings requiring frequent lubrication are oiled from the driver's seat by a single push on the pedal of the Luvax-Bijur Chassis Lubricator. This is mounted on the dashboard, where it can be reached by the driver's foot."
"Daily, when starting the engine, and before starting the car, depress the pedal of the Luvax-Bijur Chassis Lubricator. Push it until it stops against the dashboard, then let it go quickly. The pedal will return slowly of its own accord."
"In wet weather it is important to keep water out of the bearings in order to prevent rust and wear; therefore, when driving over wet or muddy roads, give the bearings an extra shot of oil. When driving long distances, the pedal should be depressed at least every 100 miles."

Alternative types.

The automatic system (which I believe the Rovers were fitted with as standard), and also the thermal system type, are discussed over the following pages. A supplementary page added in looks at the engine pump version, which receives pressure from the engine's own oil pump to distribute the chassis oil.

Information presented in this section is provided as an aid to classic and vintage car owners only. It shouldn't necessarily be taken as gospel, more of a useful series of pointers. It may be that since these period instructions were created, better ways have since evolved to tackle work on the components being considered. Tips and advice may be given in these period articles, but inclusion doesn't necessarily suggest that anyone involved with OCC endorses the methods portrayed. A certain level of mechanical know-how will be required in undertaking work as described in these pages, and anyone unsure of their own abilities is advised to seek further assistance. Delve into your car's inner workings only if you feel confident in your own abilities, after all - a little knowledge can be dangerous, as the old saying goes.
No-one at OCC can be held responsible for breakages and injuries that might occur, while working on a vehicle following a read of pages hosted on the site. Dabble at your own risk.
