This Technical Note deals with: - the internal specifications of the F4R engine, - replacement of the phase shifter solenoid valve seal, - replacement of the timing belt and the camshaft seals.

ENGINE AND PERIPHERALS ASSEMBLY Specifications 10 The specifications of the F4R engine are identical to those of the F4P engine with the exception of the following specifications: Engine Index Cubic capacity (cm 3 ) Bore (mm) Stroke (mm) Compression ratio F4R 730 1998 82.7 93 11/1 F4R 700 - 701 740 - 741 780 1998 82.7 93 9.8/1 10-1

ENGINE AND PERIPHERALS ASSEMBLY Specifications 10 CYLINDER HEAD The bolts can be reused if the length under the head does not exceed 118.5 mm (otherwise change all the bolts). Cylinder head tightening procedure REMINDER: to achieve correct tightening of the bolts, remove any oil from the cylinder head securing holes using a syringe. Do not coat new bolts with oil. However, if the bolts are reused, it is essential to coat them with engine oil. Tighten all the bolts to 2 daN.m in the order indicated below. 15153-1R Check that all the bolts are correctly tightened to 2 daN.m, then carry out angular tightening (bolt by bolt) of 165° ± 6°. No retightening of the cylinder head bolts following application of this procedure. 10-2

Piston marking Marking of the diameter of the pistons in relation to the diameter of the cylinder block Piston mark Piston diameter (mm) F4R (except F4R 730) F4R 730 Cylinder diameter (mm) 2 or B 82.680 inclusive to 82.690 exclusive 82.675 inclusive to 82.685 exclusive 82.710 inclusive to 82.720 exclusive 3 or C 82.690 inclusive to 82.700 inclusive 82.685 inclusive to 82.695 inclusive 82.720 inclusive to 82.730 inclusive 10-6

ENGINE AND PERIPHERALS ASSEMBLY Specifications 10 Category of cylinder block bores WARNING: it is essential to match the piston and cylinder block bore diameters correctly. To do this: the position of the holes "T", in relation to the mating surface of the cylinder block, makes it possible to iden- tify the original nominal dimension of the bore, and consequently, the diameter of the corresponding pistons. 15189R NOTE: some cylinders blocks do not have a matching hole. This indicates that they are fitted with pistons of category B or 2.
