To fit

1  For early engines with sump adaptors, ensure

that the dowels in the crankcase are fitted correctly

and put the assembly of the lubricating oil pump

against the crankcase with the drive gear in mesh with

its idler gear.  Fit new spring washers to the four bolts

which retain the lubricating oil pump and apply ’Loctite

575’ to the threads of the bolts. Fit and tighten the

bolts to a torque of 55 Nm (40 lbf ft).

2  Renew the ’O’ rings (page 142/A11) on the bobbin

which is fitted between the suction side of the

lubricating oil pump and the base of the sump. Renew

the ’O’ rings (page 142/A7,9) on the bobbin, which is

fitted to the discharge side of the lubricating oil pump,

and also on the plug which is to be fitted to the ’B’

bank side of the sump adaptor.

3 Slide the bobbin for the discharge side through the

sump adaptor and into the outlet of the pump, with the

short extension at the outer end. Fit the plug to the ’B’

bank side of the sump adaptor. Insert the two bolts,

complete with new spring washers, and tighten

securely.

4  Fit the lubricating oil sump, operation 19-1.

5 For new engines, with a single piece lubricating

oil sumps, ensure that the dowels in the crankcas e

are fitted correctly and put the assembly of the

lubricating oil pump against the crankcase.  Fit new

spring washers to the four bolts which retain the

lubricating oil pump and apply ’Loctite 575’ to the

threads of the bolts.  Fit and tighten the bolts to a

torque of 55 Nm (40 lbf ft).

6  If relevant, fit the drive gear onto the drive shaft of

the lubricating oil pump to mesh with its idler gear,

followed by a new locking washer. Apply ’Loctite 241’

to the threads of the shaft and fit the nut which retains  

the drive gear.  Tighten the nut to a torque of 120 Nm

(88 lbf ft).  If necessary, turn the nut further, just

enough for the locking washer to be bent up onto a

corner or a flat side of the nut. Bend up the locking

washer.

7  If relevant, fit the support bracket for the suction

pipe to the No.3 main bearing cap.  Fit the two bolts,

complete with new spring washers, and tighten to a

torque of 23 Nm (17 lbf ft).  Ensure that the vertic al

section of the support bracket is to the rear of the two

bolts.

8  Assemble the flange of the suction pipe to the

lubricating oil pump with a new joint and fit the two

bolts, complete with new spring washers. Tighten the

two bolts to a torque of 23 Nm (17 lbf ft).

9  Assemble the clip which fastens the suction pipe

and the integral strainer to its support bracket, apply

’Loctite 542’ to the threads of the ’U’ bolt and fit the

nuts, complete with new spring washers.

10  Fit the lubricating oil sump, operation 19-5.

Refer to the illustration (A) on page 142.

1  Remov e the nut (A14) and the locking washer

(A13) which retain the drive gear (A12). Use suitable

puller to withdraw the drive gear.

2  Remov e the s ix bolts (A10) which retain the end

cover (A4) to the body of the pump (A2) and use a soft

faced hammer to remove the end cover.

3  Withdraw the axle of the driven rotor, the driven

rotor (A6), the driving rotor (A3) and its integral drive

shaft from the body of the pump.

To assemble

1  Ensure that the ring type dowel (A5) in the body is

fitted into its counterbore in the relevant bolt hole of

the end cover, and put the end cover onto the drive

shaft.  Insert the six bolts, complete with new spring

washers, and tighten evenly the bolts to a torque of 21

Nm (15 lbf ft). Check that the drive shaft rotates freely

in the casing.

2 Fit the driv e gear onto the drive shaft, followed by a

new locking washer. Apply ’Loctite 241’ to the threads

of the shaft and fit the nut which retains the drive gear.

Hold the drive gear in a vice with soft covers and

tighten the nut to a torque of 120 Nm (88 lbf ft).  If

necessary, turn the nut further, just enough for the

locking washer to be bent up onto a flat side of the nut.

Bend up the locking washer.
