Information:
Keep all parts clean from contaminants. Contaminants put into the system may cause rapid wear and shortened component life.
1. Remove water seals (3), O-ring seal (1) and spacer plate (2).
Do not damage the dowels as the spacer plate is removed.
2. Remove O-ring seal (5) and spacer plate gasket (4). The following steps are to install the spacer plate.3. Thoroughly clean the spacer plate and the cylinder block surface.4. Install new spacer plate gasket (4) and new O-ring seal (5). If dowel in block has been removed for any reason, the overall installation height is 16.0 5 mm (.630 .020 in).5. Install spacer plate (2). Both surfaces of spacer plate, top of cylinder block and both sides of spacer plate gasket must be clean and dry. Do not use any gasket adhesive or other substances on these surfaces.6. Install a new O-ring seal (1).7. Install new water seals (3).8. Check the cylinder liner projection. See the topic, Install Cylinder Liners, in this manual.End By:a. install cylinder head
Perform Scheduled Oil Sampling on oil wetted compartments after performing service work to check for contaminants left in the system following repair. Contaminants put into the system may cause rapid wear and shortened component life.
