• Torsion Spring should be at an angle of 60±2°. Lay the spring over the drawing below to see if
the spring is made properly.
• Plunger pins should be centered on shaft. If either pin is loose DO NOT use the plunger. The
pins should be checked before installing.
• (Rev 3) Replace both roll pins on all reworked assemblies.
• (Rev 4) Effective 3/3/97 a large nylon washer will be added between the coil pin and the c-clip
on the plunger. To install, the c-clip has to be removed, then put the large washer on the
plunger and push it down against the coil pin. While holding it in that location, re-install the c-
clip. Now the Small nylon washer and spring can be put on the plunger and inserted into the
solenoid.
