NEW!.. S & S BILLET ALUMINUM OIL PUMPS FOR BIG TWINS
CNC machined to maintain close tolerances and strict quality control, these billet oil pumps all feature the same oiling pattern as 1981 -up engines. This results in split oil path that applies more pressure to the top end for longer component life. Each pump features multiple oil ports for a variety of plumbing options. Kits include: billet oil pump, supply and return gears, drive shaft with keys and snap rings, check ball and spring, pressure relief valve and spring, check ball and relief valve cover screws with O-rings, gaskets, fittings, and hardware. No provision for rear chain oiling.

S & S DIRECT REPLACEMENT OIL PUMP KITS
The S & S oil pump incorporates the latest design features to supply 33% more oil than early stock cast iron oil pumps. Each S & S pump is machined with a pressure relief passageway above the oil pressure valve to allow trapped air and/or oil to bleed off quickly - valve operation is improved resulting in consistent oil pressure regardless of temperature or oil viscosity. A special bypass arrangement recirculates excess oil (above engine requirements) back to the supply side of the pump minimizing oil cavitation. Installations from 1936-1969 and 1981 -up are strictly bolt-on and require no modifications. Engines from 1970-1980 require a simple drilling step and engines from 1970-1972 require a plugging step - both steps can be performed while the engine is in the chassis. Each kit comes complete with oil pump assembly, paper gaskets, drive gear key, snap ring, mounting hardware kit that includes both early style and late style mounting bolts, and easy to follow instructions.

REVTECH OIL PUMP KITS
These kits are available in chrome-plated or polished versions for most For all Big Twin Models 1936 to present. The RevTech® oil pumps were designed to take advantage of all the improvements made over the years to the Original Equipment pumps. Even 1936 thru 1980 models can be easily fitted with a RevTech® oil pump to take advantage of these features which include an improved oil pressure regulation system that ensures perfect oil control to all  areas of the motor at all times, especially during initial start-up. All the oil line fittings and mounting hardware are chrome-plated. The oil pump body and cover have a redesigned smooth outer surface with counterbored holes for the sockethead mounting hardware that really enhances the overall style and appearance. The oil feed line can be routed to the stock location at the top of the cover or directly to the pressure gears through a fitting located at the bottom of the cover. The oil that lubricates the front and rear chains can be easily adjusted or blocked off entirely for belt drive applications with pipe plugs. These RevTech® oil pump kits were engineered and designed to be bolted right onto all engines 1936 thru 1969, or 1981 to present. Engines 1970 thru 1980 will require a small drilling operation, and 1970 thru 1972 engines will also need a plugging step. Both of these modifications can be easily done while the engine is still in the frame using CCI #20-265 oil pump drill fixture.(sold separately). Each kit includes all the snaprings, keys, gaskets, shaft, fittings, mounting hardware (1/4"-24 early-style and 1/4"-20 late-style) and detailed instructions.

This allows the owner to select from 3 output pressures: 20, 24 or 26 p.s.i. at road speed (55-60 mph) while maintaining a 10 p.s.i. minimum at idle. Adjustable spring kit combines a pressure relief cap and spring that allows for precise oil pressure adjustment with the turn of screw. Simply turn the thumbscrew to increase or decrease pressure. Allows "fine tuning" pump pressure for optimum performance.
