MOTORCYCLE ENGINE TOOLS FOR HARLEY-DAVIDSON AND TRIUMPH BUILDS

Doing engine work without the right tools means improvising on jobs that have no margin for error. Crankshaft timing, valve adjustment, bearing installation, and primary locking all require specific harley special tools because the geometry and torque involved make general-purpose substitutes a liability. The engine tools here are built for the platforms builders actually work on: Harley-Davidson Big Twins and Sportsters across multiple generations, and vintage Triumph and BSA motors where factory tooling is increasingly hard to source.

HARLEY-DAVIDSON ENGINE TOOLS

Platform-specific tools covering Big Twin and Sportster applications:

• Crankshaft Turning and Rotation Tools: The Lowbrow Customs crankshaft turning tool covers 1954 to 2005 Big Twin. Fast Eddy Co. engine rotation sockets cover 2007-up Big Twin (24-spline) and Sportster XL (6-spline). Rotating the engine to TDC accurately is the foundation of any ignition timing or valve train service.

• TDC Top Dead Center Tool: The Lowbrow Customs TDC tool threads into the 14mm spark plug hole and confirms piston position without removing the primary cover. A straightforward tool that eliminates guesswork on timing setup across most Harley platforms.

• Primary Drive Locking Tools: The Lowbrow Customs primary drive locking block covers most Big Twin applications and prevents the compensating sprocket from rotating during nut removal. The Colony compensator sprocket nut tool covers 1955 to 1970 FL/FLH and 1957 to 1976 Sportster.

• Bearing Race and Sprocket Tools: Fast Eddy Co. bearing race removers and installers cover crankcase Timken races and wheel bearing applications. The sprocket shaft bearing installer covers 1955 to 2002 Big Twins where pressing in the bearing without a proper tool risks case damage.

• Connecting Rod and Pinion Tools: Fast Eddy Co. connecting rod alignment tool covers 1936 to 1999 Big Twins and all Sportsters. The pinion nut socket covers 1954 to 1992 Big Twins. The pinion gear locking tool covers 1954 to 1999 platforms.

• Engine Stands: Lowbrow Customs engine stands are available for the Twin Cam A and the 45 Flathead, both at $65.99. A proper stand keeps the motor stable and correctly oriented during a teardown or rebuild without improvising with wood blocks and floor jacks.

TRIUMPH AND BRITISH MOTORCYCLE ENGINE TOOLS

Vintage Triumph and BSA tooling is harder to find than Harley equivalents. The British Standard and Lowbrow Customs tools here cover the most common service points:

• Valve Tools: British Standard valve adjusting tool for Triumph and British motorcycles, and a valve spring compressor for Triumph and BSA. Both are purpose-built for the valve geometry on unit and pre-unit motors where aftermarket substitutes often do not fit correctly.

• TDC Tool: The Lowbrow Customs TDC tool covers 1963 to 1982 Triumph 500, 650, and 750, and 1969 to 1972 BSA A50 and A65.

• Tappet Block Tool: The Lowbrow Customs tappet block removal drift covers Triumph unit and pre-unit motors, a job that damages the cases if driven in or out without the correct tool.

• Cam Gear Puller: British Standard cam gear puller and installation tool for Triumph 500 and 650, covering the factory OEM spec for cam gear removal without crankcase damage.

ADDITIONAL ENGINE WORK TOOLS

• Pushrod Wrenches: Unity Manufacturing solid and hydraulic pushrod wrench sets for adjusting pushrod length during valve train setup on Big Twin motors.

• Bore Plug Sets: 9 Finger Fabrication engine case bore plug sets cover Twin Cam, Evolution, Shovelhead, and Sportster cases during pressure testing and assembly.

• Clutch Tools: Cycle Standard 10-stud clutch hub puller and primary clutch tools for primary disassembly. Browse the full motorcycle transmission tools range for gearbox-specific tooling alongside the engine work.
