During my annual inspection and service I choose to replace the lower water pump belt on my Cat 3126. I carefully loosened the bolts to the tensioner and slipped the old belt off on installed the new belt. In a some what ackward position I was able to put the right amount of tension on the new belt using a small breaker bar in the designed spot and a 3/8 inch racket.... I installed a new serpentine belt and sat back to look at the job.
Using the 3/8 inch rachet I checked the bolt security. The lower bolt on the adjuster was fine , When I checked the torgue on the upper bolt I heard a small TINK...the upper bolt spun
...The bolt casting had cracked ! half of the bolt casting came off when I removered the tensioner...Does any one have any advise on changing the water pump ?...Any ideas on what this might cost ?
