At Timik Engines, near Southampton in Hampshire, we specialise in remanufacturing quality diesel engines on-site. As proud members of the Federation of Engine Re-manufacturers, we ensure every engine meets the rigorous standards of BSI AU 257:2002, part of the British Standard Automobile Series.
The Perkins 1004.42 Short Block for AR build code is a 4.2 litre 4-cylinder diesel short block assembly with naturally aspirated induction and direct injection. Produced from 1994 to 2004, this short block was specific to the AR build code specification.
It was designed for Hyster and Yale forklifts including the S80-155XL and H80-155XL models, as well as JCB, Scat Trak, C70 tractors, and TS6-44/TS8-44 sweepers. The short block configuration includes the engine block, crankshaft, pistons, connecting rods, and bearings.
It excludes the cylinder head and ancillary components, allowing rebuilders to reuse serviceable heads and peripheral equipment while replacing the core rotating assembly. The AR build code denotes specific engineering requirements for the applications in which this block was used.
Parts availability is strong through Perkins networks, and the short block design allows for straightforward rebuild to original specifications. Post-assembly, each engine undergoes rigorous dynamometer testing, guaranteeing reliable operation under realistic conditions.
