SECTION 2: DRIVE BELT

Shown on the right is a typical pump belt tensioner for your 
model mower. This is how you can adjust the belt pump 
belt tension on your mower. There are two jam nuts on an 
all thread that need to be adjusted in ordered to change the 
tension in the spring

. 

Use a  3/4" wrench and a deep socket in order to loosen the 
two nuts. Tighten the outside nut if more belt tension is 
desired and loosen the outside nut if less belt tension is 
desired. 

The pump belt tension should be set between 60-65 lbs. 
This should be measured with a belt tension gauge. Your 
dealer or service center will have a belt tension gauge or 
you can buy one (Part Number 041-9999-00).
