684639 Oil Pressure Bypass Shim For 99-06 Twin Cam engines (except 06 FXD models). Increases spring pressure on oil bypass valve. Use to raise low rpm oil pressure. Reduces lifter noise on engines with low oil pressure at low rpm, increases oil flow 614762 Oil Pressure Bypass Shim, Sold each 9 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 81-99 engines. This results in a 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.

ENGINE APPAREL Relief Valve Remover Tool by Feuling Use for easy removal and installation of relief valve and spring. Holds spring away from roll pin. Fits all Twin Cam engine plates. 622171 Relief Valve Remover Tool, Sold each Chrome ‘Tight Spot’ Sockethead Oil Pump Fitting by Rivera No more custom wrenches, scraped knuckles, damaged fitting edges or leaky oil pump fittings! • Uses a 5/16" sockethead wrench to tighten or loosen • Precision machined from solid brass and show-chromed • Replaces the 90º fitting on top of the oil pump body • Replaces Original Equipment 26338-68 667499 Fits Big Twin models from 68-91 S&S Crankcase Breather Valves for Twin Cam 88 Models By installing pressure sensors in the crankcase, cam chest and rocker covers S&S determined the source and solution for the problem of “oil carry-over”, or in other words, oil out the breather. The result is an ingenious valve that is installed over the pinion shaft and inside the pinion bearing boss. It’s contained between the pinion bearing outer retaining ring and the oil pump. Also increases midrange horsepower and torque very slightly. 601115 Fits all Twin Cam 88 models (except Softail models) from 99-02 622164 Pressure Relief Valve Plunger Kit by Feuling Camplate pressure relief valve plunger, spring and roll pin.

Made in the USA. 24572 Fits Big Twins from 36-95 688250 688251 Oil Line Retainers for Twin Cam Models Every time the oil lines are removed from the oil tank these retainers should be replaced in order to avoid any leakage. 688250 Oil line retainers (pr) to engine OEM 63632-00 688251 Oil line retainers (pr) to tank OEM 63783-00 Breather Valves for Big Twins These are Original Equipment plastic breather valves for Big Twin models. 75201 Late 77-99 (except 99 Twin Cam) (repl. OEM 25310-82A) JIMS Breather Valves Aerospace-quality steel breather valves with very precise breather timing. An excellent upgrade for stock plastic breather valves. Oversized versions allow repair of worn case without welding and machining. 20936 Fits all Big Twins (except Twin Cam 88 models) from late 77-99 (repl. OEM 25313-77) 20935 +.030 oversize for Big Twin models (except Twin Cam 88 models) from late 77-99 20937 Fits Big Twin models from 48-E77 (repl. OEM 25313-73) 20938 +.030 oversize for Big Twin models from 48-E77 U.S. Patent #4,869,213 RevTech Adjustable Breather Valves Permit the engine builder to alter breather timing to match the displacement of the motor. Increasing the stroke or cylinder bore changes the total volume of the crankcase. If the breather is not modified, the cylinders fight the pressure build-up in the lower end that a stock breather cannot relieve. RevTech offers an all-steel breather valve for Big Twins from late 77-99. It’s designed to replace the stock steel or plastic breather valve and with its removable gear, permits you to dial in the exact timing needed to ensure proper scavenging. Includes a selection of four different-sized thrust washers. Fit engines from late 77-99 (except Twin Cam 88 models). 58076 RevTech breather valve, stock duration. 58077 RevTech breather valve, +10° duration. 58079 RevTech +.030" oversize breather valve, +10° duration. S&S Breather Valves These steel breathers for Big Twins are designed to replace and outperform their Original Equipment counterparts. Special Design Features: • Steel vs. plastic means greater durability and strength. Particles are less likely to get imbedded in the gear which can damage the crankcase breather gear cavity. • A screen vs. slots means better protection. Particles are stopped from getting to the gear cavity where they may damage the gears or pump. • S&S steel gear with welded in screen with larger diameter holes vs. stock steel gear with screen with smaller holes held in with a clip means improved air flow/oil scavenging from the flywheel side. • Crankcase flywheel cavity vacuum and oil scavenging in late 77-99 engines further improved with synchronizing refinements. 45845 Breather valve with shims for Big Twin models from 77-99 (except 99 Twin Cam) (repl. OEMs 25313-77A, 25313-77B) 45716 Breather valve ONLY for Big Twin models from 77-99 (except 99 Twin Cam) (repl.
