I need to tighten the Water pump belt on a CAT 3126 engine.

Customer Question

I need to tighten the Water pump belt on a CAT 3126 engine. I can't see the bolts to adjust. Do I have to tear the whole front end apart to get to them? The belt only runs the water pump. A serpintine belt runs everything else.

Hello, I'm Dale and will try to assist you. Does this single belt system have an "IDLER PULLEY or a BELT TENSIONER" ?
Customer: replied 6 years ago.
Idler pulley. I think I figured it out. I need to run to parts store to get tool to take off serpintine belt first.
Expert:  DALE replied 6 years ago.

Ok, the IDLER PULLEY will have an adjustable bolt that goes through it (after you loosen the bolt or nut in the center of the pulley).



let me know if there is anything else and good luck,

I found the bolts and fixed before the reply was received. Sorry.
