The CASE 1150E is one of the most widely serviced mid-size crawler dozers in North America — its combination of 130 hp, wide undercarriage options, and Powershift transmission made it a fleet staple throughout the late 1990s and 2000s. Service parts are still available, but without the factory manual the hydraulic system adjustments, final drive oil specifications, and undercarriage wear limits are nowhere to be found in print.
What the 1150E Service Manual Documents
The official service manual organizes every system into a standalone section that can be referenced independently during repair:
- Section 1001 — Fluids and Lubricants: Engine oil viscosity chart (ambient temperature vs. SAE grade), diesel fuel specification (No. 2 diesel, cetane minimum 45), hydraulic oil spec (AW 46 anti-wear), final drive oil (EP 80W-140 gear oil), and coolant mixture ratio. These are the exact specifications — not generic recommendations.
- Powershift Transmission: The 1150E uses a 3-speed Powershift transmission with wet disc clutch packs for each forward and reverse range. The manual documents clutch pack clearance limits, modulation valve spring specifications, and the oil pressure test procedure at the transmission charge port.
- Hydraulic System — Blade and Ripper: Variable displacement piston pump with load sensing. Main relief valve setting: 207 bar (3,000 psi). Blade tilt relief: 193 bar (2,800 psi). The manual shows test port locations on the main control valve with gauge thread specifications.
- Undercarriage: Track roller, carrier roller, and front idler removal and installation procedures. Sprocket wear limit: tooth thickness minimum 25 mm. Track shoe bolt torque: 600 N-m (440 lb-ft). Track tension adjustment: 25-50 mm sag measured at mid-span.
- Final Drives: Two-stage planetary reduction. Oil change interval: 1000 hours or annually. Oil capacity each side: 4.7 L. Bearing preload adjustment procedure with the measurement tool required.

- Engine crankcase: 18.9 L (20 US qt) — API CF-4 minimum
- Hydraulic system (tank): 53 L
- Transmission/bevel gear: 36 L combined
- Final drive each side: 4.7 L EP 80W-140
- Cooling system: 26.5 L — 50/50 coolant mix minimum

Frequently Asked Questions
What is the transmission oil specification for the 1150E?
The manual specifies UTTO meeting Case CNH spec MS-1210 or Allison C-4. This oil is used in both the transmission and bevel gear housing. Do not use straight EP gear oil in the transmission section.
Does the collection cover LGP (Low Ground Pressure) variants?
Yes. The 1150E LGP (wide track) uses the same engine and hydraulics as the standard machine. The manual notes the wider track shoe bolt torque difference and the larger idler clearance specification for LGP undercarriage.
Are the Fiat-Allis HD-series manuals English language?
The Fiat-Allis manuals in this collection are the English-language editions used for the North American and export markets.
