Sly5 Posted August 8, 2012 Share Posted August 8, 2012 I have a Mack RD 2001. The metal casing that covers the water pump as well as holds the fan on the other end of it has been cackling up of late. Made a couple of replacements in the past week. Breaks up shortly after trying to move the truck. Can somewhere tell me what could be responsible? Scared of buying another one that might just break up yet again and am loosing out on work time....

rsb502 Posted August 8, 2012 Share Posted August 8, 2012 did you replace the bearings for the water pump/fan hub?

Mackpro Posted August 9, 2012 Share Posted August 9, 2012 There is sometimes a "L" shaped bracket that goes from the cylinder head to the water pump housing. If this is missing it causes the assembly to vibrate and crack the water pump housing. Last 6 of the vin and i can maybe get u a parts pic and see if it wass equipped this way.
