CAUTION: clearence Cover up the drive belts and air 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 topls 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 clearence further repairs are necessary.If gap (A) is less than 1/4 inch (7 mm), the upper coolant hose must be replaced air 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 topls 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 clearence 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

* How important is run-out of the installed component?* air What are the tolerance or precision requirements of the specific industry topls you are in?Keith/U.S. Tsubaki: Proper selection requires more than calculating the required torque. Centering requirements, ease of installation, and the forces the unit applies to the shaft and hub also apply.Jeff/KTR: Precisely determine clearence and air the hub location required for the desired application. Evaluate the radial and axial position and the amount of space available for the locking device, and then select the type of device needed.Andrew/Whittet-Higgins: Choose the right device, taking into consideration static and dynamic loading, assembly, maintenance, misalignment, price of the full assembly, and availability.Vic/Rimtec: Avoiding keyways improves shaft maintenance. Using keyless clamping locking devices or shrink discs makes it easy to change parts.
