MEASURING RAIL-TO-ROLLER CEARANCE - TM-10-3930-647-14-P0388

. . . and four rollers that work between the intermediate rails

and inner rails.

Sharp fork truck mechanics know that with age and wear, the

...

. . . clearance between upright rails can increase and cause

excessive looseness between rails. Upright rollers become

worn, rail surfaces wear, and stress relieving due to

handling of heavy loads over a period of time may cause

slight dimensional changes between upright rails.

MEASURING RAIL-TO-ROLLER CEARANCE

The method for measuring rail-to-roller clearance is

quite easy.

We'll use this graphic example that shows the upright

rails without flanges, to show how it's done. The

t r i p l e stage upright has four sets of rollers.

One set at the top of the outer rails . . .
