General Engine Data for Leyland 98mm Engines

Below is a scan of the General data for the 98mm engine which was fitted in the Leyland 255, 270, Middleweight tractors and the Leyland 285, 485, 2100 and 4100 Heavyweight tractors, it covers both the 4/98 and 6/98 NT and DT engines. This information is from the original workshop manual supplement issued by British Leyland. I find it interesting that they give all this information but also put a disclaimer in the manual as well. Disclaimer (i) Purchasers are advised that the specification details set out in this Suppliement apply to a range of engines and not to any particular engine. For the specification of any particular engine Purchasers should consult their Distributor or Dealer.(ii) The Manufacturers reserve the right to vary their specifications with or without notice, and at such times and in such manner as they think fit. Major as well as minor changes may be involved in accordance with the manufacturer's policy of constant production improvement.
