MARK ONTO REPLACEMENT FRONT PLATE
IMPORTANT: Replacement front plates do not have
an injection pump timing mark. It is
extremely important that the timing
mark be accurately transferred from
original front plate to the replacement
plate in the exact location for correct
injection pump timing.
1. Position DFRG5 Aluminum Template (B) onto original
front plate (C) as shown. (See Group 199, Dealer
Fabricated Tools for manufacturing details.) Install
three 3/8-16 cap screws securely.
2. Transfer injection pump timing mark (A) from previous
front plate onto template using a fine tip marker and
straightedge. Remove template from front plate being
replaced.
