26. Adjust the carburetor idle speed and fuel-air mixture to speci-
fications. Check governor operation.
CAMSHAFT BEARINGS
The service bearings for the camshaft are pre-sized and require
no machining after installation. When one bearing requires re-
placement it is advisable to replace all three, as camshaft align-
ment may be affected if only one bearing is changed.
The camshaft front and rear bearings are both approximately
31' 4 inch wide, the front one having an additional oil hole for the
rocker arm shaft oil feed, and the center bearing approximately 5/8
inch wide. Install the bearings using a replacer in addition to the
adapters previously used. Make sure that the oil holes in the
bearings and cylinder block are correctly aligned before installa-
tion and that the splits in the bearings are upwards and outwardsat
45 degrees to the vertical.
Removal
Remove camshaft following the appropriate procedures in this
section.
1. Remove the flywheel.
2. Remove the crankshaft rear oil seal carrier.
3. Remove the camshaft bearings.
4. Check all the oil passages to make sure that they are clear.
Apply an oil resistant sealer to the oil gallery plugs prior to
installation.
Installation
1. Install new camshaft bearings. Make sure that the oil holes in
the bearings and cylinder block are aligned. The splits in the
bearings should be upwards and outwards at 45 degrees to the
vertical (Figure 40).
2. Install a new crankshaft rear oil seal using Tool 2 1-059A.
3. Position a new gasket to the rear oil seal carrier using an oil
resistant sealer at the ends. Install the carrier on the cylinder
block and tighten the bolts evenly to specification.
4. Locate the flywheel squarely on the crankshaft flange. Tight-
en the attaching bolts to specification.
5. Install the camshaft and related parts following the appropri-
ate procedures in this section.

OIL PUMP
The oil pump and filter assembly is bolted to the right side of the
cylinder block and can be removed with the engine in place.
Removal
1. Place a drain pan under the oil pump.
2. Remove the oil filter from the oil pump.
3. Remove the three bolts attaching the oil pump and remove the
assembly.
Installation
1 6 Ensure the mating surfaces are clean of old gasket material,
then install the oil pump assembly on the cylinder block, using
a new gasket together with an oil resistant sealer and secure
with the three bolts. Tighten the bolts to specifications.
2.
Install the oil filter to the oil pump assembly.
3. Check the oil level and add oil if necessary.
4. Start the engine and check for oil leaks.
OIL PAN
Removal
1. Drain the crankcase.
2. Remove the oil level dipstick.
3. Remove the three bolts and remove the starter motor.
4. Remove the oil pan attaching bolts and remove the pan and
gasket.
Installation
1. Clean the ail pump inlet tube and screen assembly.
3 I. Clean the gasket surfaces of the block and oil pan. Be sure
to
clean the seal retainer grooves in the cylinder front cover and
the rear seal retainer. The oil pan has a two-piece gasket. Coat
the block surface and the oil pan gasket surface with oil-
resistant sealer. Position the oil pan gaskets on the cylinder
block.
3. Position the end seals with the chamfered ends into the
grooves, again using an oil resistant sealer. Position the oil
pan and tighten the bolts evenly to specifications following
first the alphabetical, then the numerical sequences shown in
Figure 39.
4. Clean and install the starter motor, securing it with the three
bolts.
5. Refill the oil pan with the correct grade of engine oil and install
the dipstick.
6. Start the engine and check for oil leaks.
FLYWHEEL RING GEAR
The flywheel ring gear is located in a retention groove and can
be removed by cutting between two adjacent teeth with a hacksaw
and splitting the gear with a chisel. In no circumstances should
pressure be applied in an attempt to remove the ring gear for
repositioning on the flywheel.
When installing the ring gear it must be heated evenly to a
temperature of 260 to 280°C (500-535°F). Do not exceed 290°C
(554°F) as the ring gear wear resistant properties will be destroyed.
If the ring gear is to be heated by direct flame, place the ring gear
on a metal plate approximately 2 to 3 mm (.079-. 118 in.) thick and
heat plate from below in the area of the ring gear (Figure 4 1) until it
reaches the required temperature. The correct temperature can be
detected by using a special type of temperature sensitive crayon.
Fit the ring gear with the chamfers on the leading faces of the gear
teeth relative to the direction of rotation. Allow the ring gear to
cool naturally in air. Do not quench.
