DISASSEMBLY AND ASSEMBLY (Continued)

4. Using an arbor press and Piston �in Remover and

Replacer T68P-61 35-A, press piston pin (61 35)

from piston and connecting rod.

PLATES

A8121-C

Check the fit of a new piston in the cylinder bore

before assembling piston and piston pin to connecting

rod. Refer to Section 03-QO.
The piston pin bore of a connecting rod and diameter

of piston pin must be within specification. Refer to

Specifications as described.

1 . Apply light coat of clean engine oil to all parts.

2. Start piston pin in piston and connecting rod (this

may require a very light tap with a mallet). Using

an Arbor Press and Piston Pin Remover and

Replacer T68P-6 135-A, press piston pin through

piston until the piston pin is centered.

INSTALLATION

OPERATION

A8122-C

3. Check end gaps of all piston rings. It must be

within specification. Follow instructions

contained on piston ring package and install

piston rings. Refer to Section 03-00.

4. Check piston ring side clearance of compression

rings with Feeler Gauge 08 1 L -420 1-A or

equivalent by inserting it between piston ring and

its lower land. This gauge should slide freely

around entire piston ring circumference without

binding. Any wear that occurs will form a step at

inner portion of lower land. If lower lands have

high steps, piston should be replaced.

Make sure connecting rod bearings and bearing

bore in connecting rod and cap are clean. Foreign

material under connecting rod bearings will distort

connecting rod bearings and cause a failure.

Install connecting rod bearings in connecting rod

and cap with tangs fitting in slots provided.

Oil Pump
Disassembly

1 . If necessary, remove oil bypass filter (67 14).

2. Remove oil pump and filter body (6603) to engine

front cover retaining bolts and remove oil pump

and filter bod from engine front cover (60 1 9).

Lift pump gear

of pocket in oil pump and filter

body.

4. Remove oil pump body seal (6C639) and discard.

Clean sealing surfaces of engine front cover and

oil pump and filter body.

6. Using a straightedge and feeler gauge, measure

across mounting surface of engine front cover for

wear or warpage . .

7. If surface is out of flat by more than 0.04 mm

(0.00 1 6 inch), replace the engine front cover as

described.

Assembly

1 .

CAUTION: Failure to properly coat the oil

pump gears may result in failure of the pump

to prime when engine is started. Do not use

chassis lubricants.

Lightly pack gear pocket with petroleum jelly or

coat all gear surfaces with Engine Assembly

Lubricant D9AZ-1 9579-D or equivalent meeting

Ford specification ESR-M99C80-A.

Install gears in oil pump and filter body pocket.

Make sure petroleum jelly fills all voids between

gears and pockets.

Position oil pump body seal. Install oil pump and

filter body to engine front cover using alignment

dowels on engine front cover.

lighten oil pump and filter body retaining bolts to

23-32 N·m ( 1 7-23 lb-ft) for M8 bolts and 8-1 1 N·m

(7 1-97 1b-in) for M6 bolts.

Oil Pressure Relief Valve

Removal

1 . After drilling a hole through valve plug, remove

plug with a slide hammer or by prying.

Remove spring and pressure relief valve from

bore.
