Part Numbers for Common Repair Parts

Air Chamber Diaphragms:

Air Chambers were used on many machines as low cost, high force cylinders to operate a variety of mechanisms. They contain an internal 'rubbery' diaphragm that is subject to failure and subsequent replacement. Here is a stock number listing for the replacement diaphragms for the several types of air chambers used on Lucas machines:

Belts:

Cog Belts are used as the 'final drive' for high-speed Spindle Rotation on many Lucas models. The following chart will help you determine which belt stock fits your machine.

* = NOT AVAILABLE
() = Mechanical Modifications Required

Machine Hand-cranks:

Many machines use hand-cranks. The older types of cranks were unsafe, since they could be 'forgotten' on the shaft when the machine was returned to power operation. The crank listed below has a 'kick-out' mechanism to not allow the crank to be forgotten while still on the shaft.

Way Wipers:

Early Lucas way wipers (in the days before commercial wipers became available) were actually Lucas part numbers. We no longer stock individual part numbered wipers for the earlier machine models. Part number 905781 is a 'stick' of way wiper material that may be trimmed to length and used to replace most of the individually numbered parts after drilling suitable mounting holes. The 'T' and the 'DC' series of machines continue to use individually part numbered wipers. We have packaged kits of wipers for these models. Each kit should contain the proper quantities and sizes of individual way wipers to fit the largest machines of these models. Smaller machines may have an excess quantity of certain wipers that can be used for future 'spot' replacement duty.
