A Powerful Workhorse from Ford’s 40 Series

Timik Engines supplies fully re-manufactured turbocharged diesel engines for the Ford 7840 tractor. Manufactured between 1991 and 1995 at Ford’s Basildon plant in Essex, the 7840 was part of the PowerStar 40 Series and quickly established itself as one of the most capable mid-range tractors of its era.

The Ford 7840 is powered by a 6.6-litre, six-cylinder Ford Genesis turbocharged diesel engine producing 100hp. Available in 2WD and 4WD configurations, the 7840 came in three variants: the 7840S, 7840SL, and the premium 7840SLE with its closed-centre load-sensing hydraulics and 16-speed Pulse Command powershift transmission.

The 40 Series represented a significant step forward from the earlier 10 Series tractors, with improved cab comfort, better hydraulic capacity, and more refined powertrains. The 7840 sat in the middle of the range, offering enough power for serious arable and livestock work without the running costs of the larger 8240 and 8340 models.

Many Ford 7840 tractors remain in active service today, particularly on mixed farms where their combination of power, reliability, and relatively straightforward mechanicals makes them a practical choice. Remanufacturing the engine is often the most cost-effective way to keep these machines working productively.

Key Features of the Ford 7840 Turbocharged Diesel Tractor Engine:

  • 6.6-litre, six-cylinder turbocharged diesel (Ford Genesis)
  • 100hp gross power output at 2,100 rpm
  • 112mm bore, 127mm stroke, 17.5:1 compression ratio
  • Proven reliability in demanding agricultural applications
  • Strong parts availability for ongoing maintenance

How we rebuild the Ford 7840 Turbocharged Engine

Step 01

Core Restoration

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.

Step 02

Reassembly

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.

Step 03

Quality Assurance

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.

Guide pricing

Prices exclude VAT.

Engine as described from £5,450 + VAT
Block porosity treatment £350 + VAT (optional)

What is block porosity treatment?

Ford tractor engine blocks are prone to microscopic pores and casting voids that can allow coolant to seep into the oil over time. Block porosity treatment seals these voids using a vacuum impregnation process, where resin is drawn into any leakage paths and cured under pressure. This significantly extends engine life and reduces the risk of coolant contamination after rebuild. We recommend this treatment for all Ford engines where long-term reliability is a priority.

Exchange policy

All engines are supplied on an exchange basis. You send us your existing engine and we return a fully remanufactured unit. If you do not have a donor engine, contact us to discuss surcharge options.

Donor engine requirements

Donor engines must be complete (block, head, crankshaft, and major castings intact). Engines with severe damage may incur additional charges. Contact us before dispatch for assessment.
