4A-27 90-13645--2 495 POWERHEAD
Any GREASE used for bearings INSIDE the
Powerhead MUST BE gasoline soluble. Use only
Quicksilver Needle Bearing Assembly Lubricant
(92-42649A-1) or 2-4-C w/Teflon (92-825407A12). If
other lubricants are used inside the Powerhead,
damage to engine may occur.
CAUTION
Assembling Rod to Piston
Place clean needle bearings on a clean sheet of
paper and lubricate with Quicksilver Needle Bearing
Lubricant (92-42649A1) or 2-4-C w/Teflon
(92-825407A12).
NOTE: There are 29 needle bearings per piston.
Never intermix new needle bearings with used
needle bearings at the same connecting rod end.
Never intermix needle bearings on one
connecting rod with those of another connecting
rod. Should one (or more) piston pin needle
bearing of a connecting rod require replacement
(or should one or more be lost), replace all of that
connecting rod’s piston pin needle bearings.
CAUTION
Place sleeve, which is part of Piston Pin Tool
(91-74607A1), into connecting rod and install needle
bearing around sleeve, as shown.
