6.0L PCM - Belt Issues

behindpropellersbehindpropellers Posts: 189 Baller
Has anybody had any troubles with the smooth idler pulley on their 6.0 PCM? Ours fell apart - seems like failure over time to heat. Caused the belt to slip off and then rub 1/2 of the idler off. I put the automotive steel idler/belt on but it also has bt of wobble and the belt wants to slide off toward the back of the boat. I'm thinking the washer is worn out or the casting is fretted, allowing the idler to move.

Mainly curious if anybody has had the same problem??

    I had a belf failure that trashed the idler pulley (or vice versa). Replaced the idler with the slightly larger diameter steel automotive version and a slightly longer belt with no additional issues.

    Not an uncommon problem. There is really nothing special about the idler unit, probably off a caddy anyway.
