Expansion chamber — cap made of corrosion resistant cast Large capacity rubber diaphragm aluminum; rubber diaphragm allows — expands with heat and oil to expand and contract during pressure to minimize water operation. Vented cap prevents pressure buildup, prevents seal from leaking. Input and output bearings Threaded endcap — allows — American made and case accurate bearing preload to hardened to provide the highest increase bearing life. quality and load rating available in the industry. 52:1 gear ratio — full recessed tooth design keeps oil between Worm gear — high strength engaged...

Expansion chamber — large open volume to minimize internal pressure changes with temperature changes. Input and output bearings — Chinese through-harened bearings. Shims — used to set bearing preload. Worm gear — high strength ductile iron provides significantly longer wear life than steel when combined with a cast iron bull gear. 52:1 gear ratio — full recessed tooth design keeps oil between engaged gears. Long output shaft — exclusive to Valley gearboxes. Provides extra clearance between the gearbox and wheel flange, reducing mud buildup, resulting in reduced seal damage and extended...

Drive Units for Every Application 4-Wheel Articulating Track Drive

Track Drive Articulating Track Drive Four drive braces on each side Improves span alignment when crossing deep ridges, balances the load Wide wheel base Improved span stability on rolling ground and in windy conditions Wide range of tire sizes Traction and floatation options to match field conditions Three driven tires More traction to help prevent stuck drive units Heavy duty base beam Strength to support center tires on ridges Increased traction Helps prevent stuck drive units Heavy duty steel tracks Distributes weight over a wider area than tire options, minimizing ground pressure...

Valley Center Drive Valley Center Drive ®

Stator — can be replaced independent of rotor, and is held in place with corrosion-resistant, stainless steel bolts for easy maintenance Large 13/16" motor shaft Extra-large motor bearing Pinion gear— integral with motor shaft Exclusive coating — applied to internal surfaces to prevent corrosion Extra-large intermediate gear bearings — assure longer life Watertight seal— between housing components Finned aluminum housing— for cool-running efficiency. Operates at temperatures 20˚ F (11˚ C) lower than comparable motors with steel housing, because the Valley aluminum housing and fins dissipate...

The VS-7000 center drive offers the performance you have come to expect from Valley, but at a lower price. The VS-7000 is similar to the original Valley center drive except that the VS-7000 has a corrosion-resistant painted steel housing. • Same performance specifications • Same helical gearbox • Same amp draw • Same torque rating In the Valley tradition of continuously improving our products, the center drive has been designed to be the most reliable and energy efficient unit available today. * Not available on the 8000 series. Only available in US and Canada Field and Accelerated Test...

VS-7000 – Center Drive Choice

Floatation Option Ground pressure Recommended for sandy soils and limited operating hours Maximum base beam clearance and narrow wheel track; Non-directional tires available Increased base beam clearance, a wider, shallower wheel track; Non-directional tires available Increased base beam clearance, a wider, shallower wheel track Maximum base beam clearance, a wider, shallower wheel track Radial tire for minimum ground pressure with a tire, plus maximum base beam clearance VERY GOOD Three driven tires provide increased traction; recommend with 11.2 - 38 tires Articulating 4-wheel drive keeps...
