Engine Service and Diagnostic Content

This manual details the technical maintenance of Case IH 1255 and 1455 power units, spanning 25 specialized sections. Coverage includes engine diagnosis, lubrication systems, crankshaft pulley and vibration damper maintenance, and complete engine testing benchmarks. The document describes procedures for camshaft and idler gear servicing, valve lever assembly overhaul, and piston-to-cylinder sleeve fitting. Readers gain technical insight into engine run-in schedules, cylinder head rework protocols, and injection pump timing, specifically for the EP/VA and VE fuel injection systems.

Technical Specifications and Dimensional Data

This reference includes detailed tables for bolt torque, valve clearances, and coolant capacities. Valve clearance for the intake is listed at 0.30 mm in the cylinder head specification table. Main bearing cap bolt torque is documented in a three-stage sequence with a final value of 101–109 lbf-ft. The manual details engine displacement across the D-155 through DT-402 series. For those researching how factory workshop documentation is structured, this publication offers high-depth reference values. The D-268 and DT-402 engine compression ratio is specified at 15:1. This is an official 641-page Case IH service manual covering the 1987 Case IH 1255 and 1455, documenting engine, timing, and cooling system specifications for the Neuss-build diesel engine series.
