1.4.1 REMOVAL OF CYLINDER LINER
Removal steps are as follows:
1. Cylinder Block

2. Cylinder Liner
Mark the Cylinder Liner
1. Remove the piston. Refer to section "Removal of Piston".
2. Using a paint pen, mark the position of the cylinder liner in the cylinder block. Mark both the
cylinder liner and the block. Then make another set of marks 90 degrees from the first set,
in a clockwise direction.
NOTE:
If the same cylinder liner is used again, it must be installed at an offset of 90 degrees from its last
position. This reference will not be needed if the cylinder liner is being replaced.
NOTICE:
To prevent cylinder liner damage, never use a hammer or
other unsuitable device to remove the cylinder liner.

1.4.1.3 MEASUREMENT OF CYLINDER LINER PROTRUSION
Measurement steps are as follows:
1. Clean the contact surfaces of the cylinder block, the cylinder liner, and the measuring plate.
NOTE:
Correct cylinder liner protrusion is necessary to obtain a perfect seal when the head gasket is
compressed by the cylinder head.
2. Install the liner and shim into the block without the seals.
1. Cylinder Head Bolts
Figure 5
Measuring Plate
3. Install the measuring plate (J–46180) on the cylinder block and cylinder liner. Fasten the
measuring plate to the block by inserting the cylinder head bolts into the spacers and then
threading them into the holes in the cylinder block.
4. Tighten the cylinder head bolts to 50 N·m (37 lb·ft).
1. Dial Gauge
2. Slot (4 qty.)
Figure 6
Dial Gauge
3. Feeler
5. Install the dial gauge so that the feeler on the dial gauge extends into the slot in the measuring
plate. The feeler must touch the contact surface of the cylinder block with some preload.
Support the dial gauge.

Difference Between the Four Measuring Points
Max.: 0.02 (0.0007)
Table 3
Specifications for Measuring Cylinder Liner Protrusion
[a]
Set the scale on the dial gauge to zero.
[b]
Move the dial gauge until the feeler touches the cylinder liner collar. Record the reading
on the dial gauge.
[c]
Move the dial gauge and support to the next slot, and repeat the measurement process, until
four measurements have been made, one at each slot. Record each measurement.
[d]
Check each measurement. If any one measurement records protrusion of less than 0.230
mm (0.0090 in.), or more than 0.330 mm (0.0130 in.), remove the cylinder liner and check
it according to the procedures that refer to section "Removal of Cylinder Liner".
NOTE:
There are three different cylinder liner shim thicknesses that are available, 0.15 mm, 0.30 mm and
0.50 mm.
[e]
Compare the four measurements. If any measurement differs from any one of the others by
more than 0.02 mm (0.0008 in.), replace the cylinder liner and repeat steps “a” through
“e”. If the cylinder liner measurements are within specification continue to step 7.
7. Remove the bolts, spacers and measuring plate, as installed.
1.4.2 CYLINDER BLOCK PREPARATION
This procedure is used with the (PT-2250-B) counterbore tool and (J-41065).

1. Remove the cylinder heads, pistons, liners, and other hardware.
2. Protect the crankshaft, oil, and coolant passages from machining debris by covering with a
shop towel or a suitable clean cover. Clean the top surface of the block to remove any debris
from the machining area.
3. Remove the cylinder block dowel pins using (Snap-On CG503 or equivalent).
4. Remove the coolant pump refer to section "Removal of Coolant Pump" and the rear lifting
bracket.
5. Protect internal engine parts from cutting debris using an oiled sponge filler in the cylinder
block.
6. The cutting edge of the cutting bit should be retracted to protect the cutting tool. Cap screws of
the cutter should be loose at this time.

7. Center the tool on the top of the block using the Counter Bore Cutter tool(J-41065).
8. Raise the depth stop adjustment collars and lower the tapered cutter plate into the bore. Rotate
the tool and allow it to center itself in the bore.

9. Install two opposing cylinder head bolts, with the washers and spacers through the base plate of
the tool. Tighten securely to 41 N·m (30 lb·ft.).
NOTICE:
After machining the cylinder block, inspect for the presence of a
chamfer on the edge of the balcony. Use a hand stone to break
the sharp edge if needed.
10. Raise the tapered cutter head from the block and install the depth set spacer provided. While
there is no load, extend the cutting tool outward (using a clockwise rotation of the cutting
screw) until it just touches a 0.15mm feeler gauge or shim placed next to the vertical wall of
the counterbore. Tighten the Allen head hold-down screws.
NOTICE:
Do not turn past this position or the cutter plate will fit and prevent
an accurate reading.
11. Lower the cutting plate and cutter tool into the counterbore until it just touches the lower
surface of the counterbore. Rotate the lock collars downward until they touch the bronze
bushing of the tool.
12. Set the depth of cut by adjusting the top collar upwards to allow the liner shim to be inserted
between the two collars. Tighten the thumb screw of the top collar. Remove the shim.
13. Lubricate the tool bushing. Back off the lower collar by two graduations 0.0254 mm (0.001
in. each). Rotate the T-handle clockwise with a moderate, constant pressure. Stop at random
positions to prevent creating a ridge in the counterbore. Continue backing off the adjustment
in 0.0508 mm (0.002 in.) increments for the balance of the cutting operation until the collars
come together.
14. Raise the handle and insert the spacer block under the lower collar. Remove the hold-down
bolts and spacers to remove the tool from the block.
15. Retract the cutter bit into the cutter plate to protect during storage.
1.4.3 INSTALLATION OF CYLINDER LINER
Installation steps are as follows:
1. Perform the Measurement of Cylinder Liner Protrusion procedure.refer to section
"Measurement of Cylinder Liner Protrusion"
2. Install new O-rings, clean and dry, in the cylinder block.
1. Collar Seat Insert (shim)
4. Liner Seat D-Ring
2. Cylinder Block
A. Specified in Measuring Cylinder Liner Protrusion Table
3. Cylinder Liner

3. Install Liner Seat D-Ring to Cylinder Liner. Be sure the D-ring is installed with the flat surface
of the of the ring against the liner. Be careful not to over-stretch the ring as it is installed
over the liner flange.
NOTE:
The cylinder liner collar and collar seat must remain completely free of oil.

Tolerance Codes
4. Install a new seat insert, clean and dry, into the block counterbore.
5. Apply a light coating of engine oil to the lower part of the cylinder liner, from where it contacts
the O-rings up to the bevelled area.
6. When installing a new cylinder liner, make sure that the diameter tolerance code corresponds to
the one marked on the piston. For tolerance codes location refer to the edge of the cylinder liner.
[a]
Cylinder liners with tolerance code A require a piston of code BA.
[b]
Cylinder liners with tolerance code B require a piston of either code BA or BC.
[c]
Cylinder liners with tolerance code C require a piston of code BC.

7. Install the cylinder liner, using the cylinder liner installation tool (J–46168).
NOTICE:
Do not overtighten the installation tool. This may deform the
cylinder liner and make the installation tool more difficult to
remove.
[a]
Tighten the installation tool just enough to hold the installation tool inside the cylinder
liner without turning.
NOTICE:
To prevent damage to the O-rings, the cylinder liner must
be rotated during installation.
NOTE:
If installing the old cylinder liner, offset the reference marks 90 degrees from the previous ones.
[b]
Insert the cylinder liner into the cylinder block until it contacts the O-rings. Continue to
insert the cylinder liner past the O-rings, being careful to keep turning the installation tool
until the cylinder liner is properly seated.
[c]
Remove the installation tool from the cylinder liner.
8. Measure the cylinder liner protrusion from the block. The specifications are listed in Table 4.

Measuring the Cylinder Liner Inside Diameter
9. Measure the inside diameter of the cylinder liner and check for out-of-round.
[a]
Measure at three different locations 60 degrees apart in the area of the two O-rings.
[b]
Compare the three measurements. If they differ by more than the maximum admissible
out-of-round listed in Table 2, remove the cylinder liner and inspect the two O-rings and
their seating area in the cylinder block.
[c]
If the O-rings are damaged, replace them.
[d]
Check the out-of-round again until it meets specifications.
10. Install the piston. Refer to section "Installation of Piston".
