7. Oil Pump Cover Assembly
S&S® manufactures five covers for current S&S oil pumps. Covers #31-6059 and #31-6060 have 1991-earlier mounting bolt pattern. Covers #31-6061,
#31-6062, and # 31-6063 have 1992-later mounting bolt pattern.
First step in cover assembly is to identify cover and insure that cover is correct for application. See Picture 5 and Chart 1. Customer must then
install oil line fittings and other required hardware, if applicable, in cover.
All covers require fittings for supply and return lines. Some covers offer more than one location for supply and/or return line fittings. Other covers
provide for primary chain oiler and/or oil pressure sending unit in addition to supply and return fittings.
Customer must decide which holes in cover will be used and block off holes not used with supplied pipe plugs. Correct identification of locations for
supply, return, and other pump cover fittings is critical. See Pictures 6 and 7.
Incorrect placement of oil lines or oil line fittings can cause extensive engine damage not covered under warranty. See Appendix (Page
21) for correct routing of oil pump lines.
NOTES
•
Covers #31-6061 and #31-6062 are compatible with rigid oil return and supply lines found on 1992-up rubber-mount models. In these applications,
hole #6 in face of cover is used for supply line, hole in bottom left location is used for return line. After installing elbow fitting #50-8114 for return line,
customer must install compression fitting #50-8120 (supplied in kit) in elbow rather than conventional hose fitting #50-8115. Fitting #50-8115 will be
used for supply line fitting. For use with OEM rigid oil lines, return fitting must face forward, toward front of engine. Supply fitting will face downward at
approximate 45° angle toward lower left corner of pump cover.
•
Covers #31-6059 (early bolt pattern) and #31-6061 (late bolt pattern) appear similar, and both are compatible with rigid oil return line found on 1992-up
rubber-mount models. HOWEVER, holes in face of covers have different functions. Hole #3 in face of cover #31-6059 is high-pressure site intended for oil
pressure sending unit. Hole #6 in face of cover #31-6062 is low-pressure site for oil supply line from tank. This and differences in mounting bolt pattern
prevent covers #31-6059 and #31-6061 from being interchangeable. See Picture 5.
•
Always apply PTFE plumber's tape or pipe sealant such as Slic-tite to threads of fittings before assembling fittings or installing fittings
in cover. Failure to install fittings correctly may damage cover and void warranty.
•
Apply tape and pipe sealant to threads only. Avoid using excessive amounts that may protrude into and obstruct oil passages or
contaminate engine oil. Incorrect use of PTFE tape or pipe sealant may cause engine damage not covered under warranty.
A. Cover #31-6059 - See Pictures 5 and 6. Fittings for oil supply and return lines can be placed in holes at either bottom or top of cover
according to installerís requirements. Hole #3 in face of cover is intended for oil pressure sending unit. This hole cannot be used for supply
or return line! Cover #31-6059 also has provision for primary chain oiler.
NOTE - Although hole #3 provides adequate pressurized oil for top end lubrication in Panhead-Shovelhead and similar applications, S&S recommends
this site be used for pressure monitoring only. Oil from hole #3 bypasses hydraulic lifter filter.
1. Preparation - Apply PTFE tape or pipe sealant to threads of 2 ea. 90° elbow fittings #50-8114, 2 ea. hose fittings #50-8115, and 2 or 3 ea.
1⁄8 -27 pipe plugs #50-8331, depending on whether oil pressure sending unit/gauge will be used in hole #3. If 1992-up rigid return line
is used, substitute compression fitting #50-8120 for 1 hose fitting #50-8115. If primary chain oiler is used, apply tape or sealant to 1⁄16 -27
hose fitting #50-8116. If primary chain oiler is not used, apply tape or sealant to 1⁄16 -27 pipe plug #50-8332.
2. Install elbow fittings in locations #1 or #5 (return) and #2 or #4 (supply). Hole #5 must be used for 1992-up rigid return line. If applicable,
apply PTFE tape or pipe sealant to threads and install oil pressure gauge/sending unit (not supplied) in hole #3. Install 1⁄8 -27 pipe plugs
in holes not used.
3. If primary chain oiler typically found in 1965-1984 models is used, install 1⁄16 -27 hose fitting in hole #7. If primary chain oiler is not used
(belt primary drive or sealed primary housing), install 1⁄16 -27 pipe plug in hole #8.
4. Install hose fittings in elbows. Substitute compression fitting #50-8120 for hose fitting in hole #5 if 1992-up rigid return line is used.
Compression fitting must face forward for use with rigid return line.
NOTE - 1992-up rigid supply line will require modification for use with cover #31-6059.
