TightSteer©s spring-loaded plunger replaces the Ross set screw and keeps the sector shaft in full contact with the cam (worm gear) through the entire turning range of the wheel. The constant engagement of the sector shaft’s pins into the cam eliminates the free play common to early Ross steering systems.
The Ross steering box features a worm gear referred to as a cam (1) and a sector shaft (2) with two pins (3) that engage in the teeth of the cam. The teeth are moved forward or backward depending on which way the cam is turned by the steering wheel. In the standard Ross steering box, the contact of the sector shaft’s teeth are controlled by a set screw (4) which controls the depth of the teeth into the worm.
Even on completely rebuilt steering systems, the standard Ross set screw does not provide for full contact of the sector shaft’s pins in the cam through the entire turning range of the steering wheel. Also, the uneven wear caused by years of use makes it impossible for a stationary set screw to remove free play in all steering positions
The patent-applied TightSteer© unit features a machined steel body with a hardened-steel plunger. A custom spring is enclosed in the unit by a cap screw that sets the spring to the desired “standard” pressure. TightSteer© replaces the Ross set screw and threads into the coverplate of the Ross steering box.
TightSteer© cannot compensate for worn wheel bearings, worn king pins or king pin bearings, worn pitman arms or pitman arm bearings, improperly set camber, improperly set caster, improperly set toe-in, or worn tie rod ends. Ensure that these components and settings are correct before installing TightSteer©.
