7.5L Turbocharged Intercooled Power Across the TM115-TM190 Range
Timik Engines supplies fully re-manufactured turbocharged intercooled diesel engines for the New Holland TM Series, built at the Basildon factory in Essex and produced from 2000 to 2007. The TM range covered eleven models from the TM115 to the TM190, all powered by variants of the same 7.5-litre six-cylinder engine and sharing a common architecture throughout.
The series represented a significant step forward from the preceding 40 Series tractors, with a closed-centre load-sensing hydraulic system, full powershift transmission options, and a substantially more capable engine platform suited to large-scale arable and mixed farming operations.
The TM Series was available in two-wheel and four-wheel drive configurations across the range, with transmission options including Range Command and Dual Command on the mid-range models, and the full Power Command powershift on the larger TM165, TM175, and TM190. The 7.5-litre engine used air-to-air intercooling throughout the range, with power outputs tuned by variant from 115hp on the TM115 to 190hp on the TM190.
Higher-spec models also featured engine power management, allowing brief power boosts for headland turns and transport. The TM Series earned a strong reputation for hydraulic capacity and transmission refinement, and remains a capable working platform well into its third decade.
The engine fitted across the New Holland TM Series is the New Holland 675TA six-cylinder, liquid-cooled turbocharged intercooled diesel, displacing 7.5 litres with a bore of 111.8mm and a stroke of 127mm. It is rated at 2,200rpm across all variants, with a compression ratio of 17.0:1 and a firing order of 1-5-3-6-2-4.
Timik Engines re-manufactures this unit to full specification, restoring the block, cylinder head, crankshaft, turbocharger, intercooler, and rotating assembly to original factory tolerances. Where a TM Series engine has accumulated significant hours or shows signs of wear, a fully re-manufactured unit is the most reliable and cost-effective route back to full working capacity.
The engine block is bored back to standard with new liners fitted. The cylinder head is remanufactured with valve seats re-cut and new valves fitted. The crankshaft is ground to precise tolerances.
All engines are rebuilt in our clean workshop with new pistons and rings, bearings, oil pump, water pump, and complete gasket set. Fuel injection equipment is remanufactured and turbochargers replaced where applicable.
Every engine is dynamometer tested to confirm correct power output, oil pressure, and operating temperatures. Engines are painted and prepared for delivery with full documentation.
