S&S, sump set 84-91, diameter 3-5/8". 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 many have discovered at their own expense. These S&S Superstock™ oil pans can be used for both standard replacement and competition purposes. For the engine builder, the substantial labour savings achieved by using S&S oil pans are crucial. These oil pans come ‘prepared’ with Timken main bearing seats for the drive shaft installed and needle bearings for the camshaft fitted, in addition to the pinion main bearing seat, which is pressed and ground in-line. Additional parts supplied include Timken bearings for the drive shaft, cylinder studs, nickel-plated oil pan bolts, oil pan fittings, oil pressure sensor, timing and magnetic oil pan drain plugs, and a special S&S alternator stator clamp bolt. Flywheel scrapers are machined to fit original 8-1/2" diameter flywheels. S&S oil pans maximise oil suction efficiency from the sump via a breathers duct with ‘ports’ of design. S&S oil pans have clearance for capacities up to 5", requiring no additional machining for long-stroke crankshafts. S&S oil pans are delivered complete with assembly instructions.

(Keep unchanged: OEM.)
Note: For Evo Big Twin 84-E85 models, an L85-91 style cylinder head bolt kit must be used. These can be ordered separately as MCS 505266 (Gardner-Westcott) or 989599 (Colony), in 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 judge the suitability of the components in combination with the other engine components before assembly. It is important that a qualified mechanic carries out the installation and any necessary adjustments.
