Visually inspect the upper radiator hose for pressure marks and traces airtoolxuk of rubbing at the closest point of contact to the oil filter housing cast boss (see illustration). If traces of rubbing are found, the upper radiator hose must be replaced with the new style airtoolxuk hose (See Parts Information).NOTE: A modified hose was used in production from approximately mid-November 1995 through June 1996, which included an extra rubber pad attached to the outside of the hose in the critical area. If traces of rubbing are found on the rubber pad area of this type of hose, it must also be replaced with the new style hose. Visually inspect the oil filter housing for any sharp edges or burrs on the casting boss. If a sharp edge or casting burr is found on the boss, it must be removed using sand paper or a fine file.

Another important thing to consider is minimum hub thickness, which is calculated based on such factors as locking device outer diameter and surface pressure. The hub should be thicker than this value to prevent excess stress and early failure. Locking device manufacturers typically provide this formula.Andrew/Whittet-Higgins: Consider all costs of the assembly rather than the individual costs of each component.Keith/U.S. Tsubaki: Go keyless. Keys and splines weaken the shaft by cutting into it, requiring a larger shaft and accompanying parts, such as bearings, to handle the higher forces.End-user adviceWhat should END USERS do to maximize life and productivity?Carl/Ringfeder: airtoolxuk Pay close attention to the OEM''s service instructions and use the locking device manufacturer''s technical information to help with replacement or reinstallation. Warren/Fenner: In general, locking devices don''t require any maintenance or special attention to maintain their performance and maximum life.
