Case-IH MX 90C specs: hp, weight, years

Name: Case-IH MX 90C
Brand: Case-IH

PERKINS-FASTRAM 1004-40 Turbo-HR four-cylinder diesel or Perkins 1004-4T HR. The manufacturer claimed 88.8 horsepower. The only laboratory test on record is of one version: OECD Test 1929 measured 75.5 hp at the PTO of the MX 90C (4 WD). Compared at the engine's rated speed, where the brochure figure is quoted, the shaft gave 75.4 hp — 15.1% below the claim.
