Fit the idler pinion (16), paper gasket and pump base (15) (with the filter support on the outlet pipe side). Tighten
the screws to 9.4 ft.lbs (1. 3 m. kg) (spring washers under heads). Make sure that the pinions do not bind, if
so, fit a second paper joint at the pump base. Lock the milled-head screw by tapping the metal of the pump
base into the screw groove . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

On the intake opening fit: one cork seal, the top cover, the upper filter plate, a filter (large diameter hole), the
distance piece, a second filter, the lower plate.

Check the pressure on the test bench.
With SAE. 20 oil heated to 60 k 5' C and the pump outlet through a jet of 2.8 mm diameter, the pressure must be
50 lbs. /square inch (3.5 kg/cm2) at 1, 000 r. p.m. (If this pressure is not reached, renew spring (25) (see Pl. 10).
NOTE - Failing a test bench use the simplified unit MR-1811 (see Pl. 11) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
To replace the starter ring :
a)
Detach the starter ring from the flywheel, driving it off with a hammer.
b)
To fit the starter ring on the flywheel :
Heat the starter ring with a blow torch fitted with a nozzle of 800 to 1000 litres.
Heat only the bore, at the same time rotating the ring continuously to ensure uniform expansion. Cease heating
when the ring reaches a temperature of 200° to 250°C (straw colour). Above this temperature the heat treat-
ment of the ring will be modified. Make sure that the flywheel is perfectly clean and fit the ring quickly,
ensuring that it is kept perfectly level.
Grind the bearing face for the clutch disc on the flywheel (see Pl. 38) :
Each time the clutch disc bearing face "a" is ground, remove the same amount from the bearing face "b" on the
clutch housing. Effect these two operations without removing the flywheel from the lathe, so as to ensure that
both machined faces are perfectly parallel.
Grinding must not exceed 0. 3 to 0.5 mm.
The distance between the bearing face of the crankshaft and the Ferodo
disc must not be less than 15.4 mm.
Prepare the parts for the crankshaft (see Pl. 13) :
I
In general, proceed by renewing the parts.
Nevertheless, some repairs are possible :
a)
Crankcase :
If the bearing caps have been filed by careless workmen,
standard connecting rods cannot be fitted. Either a
new cylinder block must be fitted or, failing this, the cylinder bearings must be rebored. Proceed as follows :
Check the bearing faces on a surface plate for flatness. If necessary, file them flat or, better still, mill them.
Place the bearing caps (without the bearings) on the cylinder block and tighten the screws to 58 ft. lbs (8. m. kg)
(spanner 2471-T, see Pl. 7, fig. 2).
Measure the diameter "a"
with a dial gauge (dial gauge 2440-T) (see Pl. 13, fig. 2).
Make sure that the measurement "a" taken at one end of the bearing is the same as the measurement "b" taken
at the other end. If not, the bearing faces of the cap are not parallel to the centre line of the crankshaft, they
