Engine Make:
Allis-Chalmers
Engine Model:
Diesel (Specific model often a turbocharged variant, e.g., 670T or similar)
Engine Displacement:
Approx. 401 cubic inches (6.57 Liters) for the 670T engine, but variations may exist.
Engine Cylinders:
6 Cylinder
Horsepower Rating:
Advertised gross horsepower typically in the range of 130-150 HP, depending on specific configuration and turbocharging.
Fuel System Type:
Direct Injection Diesel with Turbocharger
Injection System:
Typically an American Bosch or similar inline injection pump.
Transmission Type:
Allis-Chalmers Powershift (e.g., 20-speed full Powershift)
Optional Transmission:
While primarily known for its Powershift, other configurations might have existed depending on specific market variants or later updates, though the Powershift is the defining feature.
Gear Selection:
Multiple forward and reverse gears with on-the-go shifting without clutch engagement.
Transmission Fluid Type:
Likely requires a specific tractor hydraulic fluid (e.g., UTTO) or Type 'F' automatic transmission fluid for powershift operation. Manual will specify exact type and viscosity.
Engine Oil Change:
Typically every 250-500 operating hours, depending on operating conditions and oil analysis. Manual will provide precise intervals.
Transmission Fluid Change:
Likely every 1000-2000 operating hours. Manual will specify.
Engine Oil Specification:
CD or CE grade diesel engine oil, SAE 15W-40 or 30W depending on ambient temperature. Manual will specify exact API classification and viscosity.
Hydraulic Fluid Specification:
UTTO (Universal Tractor Transmission Oil) or equivalent with specific viscosity grades as per manual. May also require Hy-Trans or similar for powershift components.
Common Wear Points:
Powershift transmission clutch packs, hydraulic pump wear, injector wear, and turbocharger seals.
Electrical Gremlins:
Older wiring harnesses can degrade, leading to intermittent electrical faults. Manual's wiring diagrams are crucial.
