VALVE SEAL REPLACEMENT
NOTE: Cylinder head removal is not required in this procedure. This procedure applies when using the in-car valve spring compressor (Snap-On
YA8845 with YA8845-2A 7/8" attachment).
WARNING: Always wear approved eye protection when using the in-car valve spring compressor.
1. Turn the crankshaft so that the No. 1 and the No. 4 pistons are at top dead center (TDC).
2. Remove the cylinder head cover and the rocker arm assembly.
NOTE: When removing or installing the rocker arm assembly, do not remove the camshaft holder bolts. The bolts will keep the holders, springs
and rocker arms on the shaft.
3. Remove the fuel injectors and the wire harness.
4. Using the 8 mm bolts supplied with the tool, mount the two uprights to the cylinder head at the end camshaft holders. The uprights fit over the
camshaft as shown.
5. Insert the cross shaft through the top hole of the two uprights.
Intake Valve Seals:
6. Select the 7/8 in diameter long compressor attachment and fasten the attachment to the No. 5 hole of the lever arm with the speed pin supplied.
7. Insert an air adaptor into the spark plug hole. Pump air into the cylinder to keep the valve closed while compressing springs and removing the
valve keepers.
8. Position the lever arm under the cross shaft so the lever is perpendicular to the shaft and the compressor attachment rests on top of the retainer for
the spring being compressed. Use the front position slot on the lever as shown.
