Gearbox spacer washer 823/M4743 JCB, aftermarket

Gearbox spacer washer 823/M4743 is an aftermarket part for the JCB machines. According to the product card, this part is a gearbox spacer washer.

Adjusting shims set the axial position of parts and the bearing preload in gearboxes, axles and other units. Shim thickness matters to hundredths of a millimetre: too thick a shim squeezes and heats the bearings, too thin a shim leaves play and upsets gear meshing. Adjusting shims are therefore chosen to the measured value, and shims of different thicknesses may be used in one unit. The measured value is recorded in the service record.
