PARTS REQUIRING ANGLE TIGHTENING

  1. Use angle wrench [SST: KV10112100 (BT8653-A)] for the final tightening of the following engine parts: Cylinder head bolts Main bearing cap bolts Connecting rod cap bolts Crankshaft pulley bolt (No angle wrench is required as the bolt flange is provided with notches for angular tightening)
  2. Do not use a torque value for final tightening.
  3. The torque value for these parts are for a preliminary step.
  4. Ensure thread and seat surfaces are clean and coated with engine oil.

Scheme 1

Scheme 1: Removal Of Liquid Gasket Sealing
  1. After removing the mounting bolts and nuts, separate the mating surface using a seal cutter (SST) and remove the old liquid gasket sealing. CAUTION: Be careful not to damage the mating surfaces.
  2. In areas where seal cutter (SST) is difficult to use, use a plastic hammer to lightly tap (1) seal cutter where liquid gasket is applied. Use plastic hammer to slide seal cutter (2) by tapping on the side. CAUTION: If for some unavoidable reason a tool such as flat-bladed screwdriver is used, be careful not to damage the mating surfaces.

Scheme 2

Scheme 2: Liquid Gasket Application Procedure

Scheme 3

Scheme 3
  1. Using a scraper, remove the old liquid gasket adhering to the gasket application surface and the mating surface. Remove the liquid gasket completely from the groove of the gasket application surface, mounting bolts, and bolt holes.
  2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating use) to remove adhering moisture, grease and foreign material.
  3. Attach the liquid gasket tube to the tube presser [SST: WS39930000 ( - )]. Use Genuine RTV Silicone Sealant or equivalent. Refer to «RECOMMENDED CHEMICAL PRODUCTS AND SEALANTS»(ref-179413-S29795405052005070700000) .
  4. Apply liquid gasket without breaks to the specified location with the specified dimensions.

Scheme 4

Scheme 4
  1. If there is a groove for the liquid gasket application, apply gasket to the groove.
  2. As for bolt holes, normally apply liquid gasket inside the holes. Occasionally, it should be applied outside the holes. Make sure to read the text of this manual.
  3. Within five minutes of liquid gasket application, install the mating component.
  4. If liquid gasket protrudes, wipe it off immediately.
  5. Do not retighten mounting bolts and nuts after the installation.
  6. After 30 minutes or more have passed from the installation fill engine oil and engine coolant.
CAUTIONIf there are specific instructions in this manual, observe them.
