Product Support Bulletin
Subject: Tractor Pin Alignment
Date: 5/15/89 PSB No: P - 0044
Page: 1 of 1 Originator: RP
The purpose of this bulletin is to insure the proper installation and alignment of
the FX- 850/1050 and LQ- 850/1050 push tractor assemblies.
There are two possible ways to install the tractor frame on the push tractor
assembly. If the frame is installed incorrectly, the tractor belt pins on the two
tractors will not be aligned, and the resulting printout appears to be slanted on
the page, or the perforated edge will be tom. This is caused by the marks on
the tractor shaft holders being 180 degrees ‘out of phase.’
When assembling a tractor, there are two grooves in the shaft, and two tabs
on the tractor shaft holder. lf the pins on both tractor belts are not aligned, it
will be necessary to disassemble the tractor, and rotate one tractor shaft holder
180 degrees, to bring it back into alignment with the other shaft holder.
Alignment can be verified by examining the marks in the shaft holders, which
will both be in the forward position when properly aligned, as shown in
Figure
4- 51 below.
