MEASURING RAIL-TO-ROLLER CLEARANCE - continued

Repeat with the

rails at one half...

... and full upright

extension ...

Here, clearance between the roller set at inner rails and

intermediate rails is found to be 3/32nds of an inch,

5/32nds of an inch, and 7/32nds of an inch. We must add

three 1/32nds inch shims to this roller set. This means

that two shims will be added to one roller and one to

the other.

Having recorded the number of shims to be added to each

set of upright rollers, we are now ready to make these

adjustments.
