ASSEMBLY INSTRUCTIONS
NOTICE
Numbers in parentheses ( ) refer to key numbers in assembly drawings on pages 35, 37, 39 and 41.
1. Make sure all metallic parts are clean and free of any nicks or burrs.
2. Lubricate the outside diameter of the lip seal (15) with a light oil or grease. Install seals in both the drive
headplate (24) and gear headplate (18). The seal lip should always face towards the bearing or lubricant. New
seals should be installed each time the headplate is removed.
NOTICE
Make sure seals are fully seated. Use extreme care when installing.
MECHANICAL SEALS ONLY
A. Lightly coat the headplate bores with assembly lubricant.
B. Refer to Figure 7-1. Install mechanical seal (A) into the headplate bore (C) using a press and the
correct driver shown on page 24. Drive the seal securely on to its seat.
Use extreme care when installing seals in the headplate bores. Do not attempt to install the
mechanical seals without the use of a press. Blows from a hammer or mallet can damage the fragile
seal surface. Too much force can crush the seal casing. Make certain the seal is properly seated and
undamaged before proceeding.
