Connecting Rod: Service Precautions

- To assure the satisfactory maintenance of the engine, some bolts and nuts must be tightened using an angular-tightening method.

- If these parts are tightened using a torque setting method, dispersal of the tightening force (axial bolt force) will be two or three times that of the dispersal produced by using the correct angular-tightening method.

- Although the torque setting values (described in this manual) are equivalent to those used when bolts and nuts are tightened with an angular-tightening method, they should be used for reference only.

- Before tightening the bolts and nuts, ensure that the thread and seating surfaces are clean and then coated with engine oil.

- The bolts and nuts which require the angular-tightening method are as follows:

Cylinder head bolts
