Valley Gearboxes…built to last

The Valley Gearbox is designed and built to work under today’s most demanding growing conditions. There’s a stronger, heavier bull gear…pre-loaded worm gear…and new shaft seals that keep oil in and problems out. A heavy-duty bronze bull gear is an available option for severe applications. Exclusive Valley Gearbox input and output seals help ensure long life for gearbox components. A Valley exclusive, these seals are standard on all new Valley equipment, or retrofit any existing Valley Gearbox.

Largest capacity rubber diaphragm — expands with heat and pressure to minimize water condensation.
Input and output bearings — American made and case hardened to provide the highest quality and load rating available in the industry to insure long trouble-free life.
Worm gear — high strength ductile iron provides significantly longer wear life then steel when combined with a cast iron bull gear.
Tooth design — industry exclusive 250 tooth angle provides 40% longer life and better reliability in tough conditions compared to normal 14 1/20 tooth designs.
Largest bull gear neck and keyway — for strength in critical load-bearing area.
Expansion chamber — cap made of noncorrosive cast aluminum; rubber diaphragm allows oil to expand and contract during operation. Vented cap prevents pressure buildup,
Threaded endcap — allows accurate bearing preload, to increase bearing life. Prevents seal from leaking.
Bull gear — high strength cast iron provides the highest load capacity in the industry and longest life. Optional bronze gear is available for extreme conditions.
Multi-viscosity gearbox oil — exceeds 85w140 GL5 oil for long gear wear under extreme load conditions.
Heaviest gearbox housing — more material in high stress areas. Designed to distribute loads more evenly.
Longest output shaft (steel) — exclusive to Valley gearboxes. Provides extra clearance between the gearbox and wheel flange, reducing mud buildup, resulting in reduced seal damage and extended gearbox life. Special offset rims position the tire back close to the gearbox to minimize bearing loads… another Valley exclusive.

All these factors add up to one thing — the best quality gearbox in the industry, giving you long, trouble-free economical equipment life.

VS-7000 Gearbox.

 

VS-7000 Drive Train is Now Available

The VS-7000 drive train is now available as a lower priced option on the 7000 series pivots. VS standsfor Valley Specified performance. The VS-7000 will provide a substantial savings per drive unit. It is important to note that the VS-7000 and Valley drive trains cannot be mixed on a given pivot. The first span selection determines which drive train choice must be used for the entire machine.

Input and output bearings — Chinese through-hardened bearings.
Worm gear — high strength ductile iron provides significantly longer wear life then steel when combined with a cast iron bull gear.
Tooth Design — 14 1/2º tooth angle
Shorter bull gear neck and keyway matching non-Valley gearboxes
Expansion chamber — large open volume to minimize internal pressure changes with temperature changes.
Shims used to set bearing preload.
52:1 gear ratio — full recessed tooth design keeps oil engaged between 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 gearbox life. Special offset rims position the tire back close to the gearbox to minimize bearing loads…another Valley exclusive.
