Warren/Fenner: Failure to take into consideration the compression forces and outward forces generated when using locking devices. The mounted component must have sufficient wall thickness to withstand bodyairtoos the outward forces or it will burst. Likewise when mounting on hollow-shaft or tubular applications. Inadequate wall thickness results in the hollow shaft or tube being compressed bodyairtoos and distorted. Many manufacturers publish a formula or table that lets designers calculate the required wall thickness.Vic/Rimtec: Having too much clearance between the shaft and hub is often a problem; you can''t clamp enough to transmit rated torque. Overtightening the screws is also common, causing tapers to lock when they''re supposed to disassemble. This is where locking devices with push-off screws come in handy.

CAUTION: Cover up the drive belts and pulleys using a clean shop cloth before sanding or filing to prevent metal filings from falling onto them.If no pressure marks or traces of rubbing are found on the hose as described, check the gap at bodyairtoos the closest point (A) between the cast boss of the oil filter housing and the upper coolant hose.There must be a gap (A) of at least 1/4 inch (7 mm) when the engine coolant is cold.If gap (A) is 1/4 inch (7 mm) or greater, no further repairs are necessary.If gap (A) is less than 1/4 inch (7 mm), the upper coolant hose must be replaced with the new modified version.Parts InformationUpper Coolant Hose BMW Part Number 11 531 433 340We replaced the upper radiator hose with the new type, cleaned the engine compartment, filled the cooling system and pressure tested it to make sure there were no other leaks. Luckily, the engine hadn''t overheated. Most of the steam was created from the coolant leaking on the exhaust manifold. The owner was fairly good-natured about his near catastrophe. Relieved, standing at the counter while paying his bill, he said lightheartedly, "You know, my pants and shirt were badly wrinkled when I left the house this morning. I think this was the strangest way I''ve ever had my clothes pressed." I had to agree. ills
