3. If prying off sections becomes necessary, take
extreme care not to mar or damage machined
surfaces. Excessive force while prying can
result in misalignment and serious damage to
parts.
4. Match mark exterior surface of housings
before separating the parts. Align match
marks during assembly.
5. Gears are closely matched. Gears must be
kept together as sets when removed from a
unit. Handle with care to avoid damage to the
journals or teeth. Avoid touching gear jour-
nals. Always replace matched parts as a
set.
6. Do not grip machined surfaces in a vise to
prevent damage to fine surfaces.
7. If parts are difficult to fit during assembly, tap
gently with a soft hammer. Never use an iron
or steel hammer to tap parts.
8. Never hammer bushings into bores; use an
arbor press.
