Perkins 1104D Industrial Diesel Engine Operation & Maintenance Manual
Instant Answer & Quick Specs Box
Engineering Overview & Technical Coverage
The Perkins 1104D (Mech) series is a four-cylinder, 4.4-liter heavy-duty diesel engine engineered for off-highway construction machinery, telescopic handlers, agricultural tractors, and generator sets. Covering engine build prefixes NK (1104D-44 naturally aspirated), NL (1104D-44T turbocharged), and NM (1104D-44TA turbocharged aftercooled), this mechanical injection platform meets EPA Tier 3 and EU Stage IIIA emissions standards. This official factory Operation and Maintenance Manual (SEBU8325-01) details daily inspection walkarounds, fluid change intervals, cold starting procedures, and routine valvetrain maintenance.

What are the valve lash settings for the Perkins 1104D mechanical engine?
Valve clearances for all Perkins 1104D mechanical models (NK, NL, NM) set on a cold engine are 0.20 mm (0.008 in) for inlet valves and 0.45 mm (0.018 in) for exhaust valves.
How often should engine oil and filter be changed on a Perkins 1104D?
Under normal commercial operating conditions, change the engine oil and spin-on oil filter every 500 service hours or 12 months, whichever occurs first, using API CI-4/CH-4 multi-grade oil.
