S&S, sump kit 84-91, STD diameter. Natural

S&S Superstock™ oil pans, manufactured from 356-T6 aluminium, are significantly stronger than the OEM oil pan. OEM oil pans can fracture in high-performance applications or even in standard applications, as we have discovered to our own detriment. These S&S Superstock™ oil pans can be used for both standard replacement and competition purposes. For the engine builder, the considerable labour savings achieved by using S&S oil pans are paramount. These oil pans come ‘prepared’ with Timken main bearing seats for the crown shaft installed and needle bearings for the camshaft fitted, in addition to the main bearing seat for the pinion, which is pressed and ground in-line. Additional parts included are: Timken crown shaft bearings, cylinder studs, nickel-plated oil pan bolts, oil pan fittings, oil pressure sensor, timed and magnetic oil pan drain plugs, and a special S&S clamp bolt for the alternator stator. Flywheel scrapers are machined to suit original 8-1/2" diameter flywheels. S&S oil pans maximise oil suction efficiency from the sump via a vented port system. S&S oil pans provide clearance for capacities up to 5", requiring no additional machining for long-stroke crankshafts. S&S oil pans are supplied complete with fitting instructions.

(Keep unchanged: OEM.)
Note: For 84-E85 Evo Big Twin models an L85-91 style cylinder head stud kit must be used. These can be ordered separately as MCS 505266 (Gardner-Westcott) or 989599 (Colony), standard lengths only.
Note: In 70-91 applications the H-D aluminium oil pump (26190-73) or the S&S oil pump, MCS 519923, can be used.
Note: In any application, the technician must be able to assess the suitability of the components in combination with the other engine components before installation. It is important that a qualified mechanic performs the installation and any necessary adjustments.
