Bulletin No. SB-875-A
SUBJECT: Modification of Propeller Straightening Fixture #377537
for #377635 prop (8¼ x 8½)
10 h.p. QD(L)-19 through QD(L)-24
We have found it necessary to modify #377537 propeller fixture - providing
additional clearance to the propeller blade at its base segment. This will
eliminate interference between propeller and fixture and prevent possible
mis-pitching during the straightening process. Merely grind a 5/16 radius
on #377537 fixture as shown in figure 2.
FIGURE 1 BEFORE MODIFICATION
FIGURE 2 AFTER MODIFICATION
All #377537 propeller fixtures in OMC Parts Depot have received this
modification, therefore, this bulletin does not apply to future purchases
of this item.
Sincerely,
JOHNSON MOTORS
