I have a '99 Holiday Rambler with the Cummins ISC 8.3 diesel, with side mount radiator, so direct access to the engine compartment is great. Over the past couple of days, I've been trying to figure out how to loosen the air compressor V-Belt tension in order to replace the belt...it seems fairly straight forward on how you would do this, but still no luck. (I've taken photos, but unfortunately they won't upload to this post)
It appears that the air compressor belt tension, is but together with a threaded bolt attached to the compressor frame and a 18mm nut secures this bolt; which looks like you would tighten or loosen the nut in order to create tension.
I've tried repeatedly to unloosen this nut (sprayed penetrating lubricants, used breaker bar), but it just won't budge. The nut/bolt does not appear to have corrosion and the bolt threads look great.
The nut does not appear to be welded or as part of the frame.
My question: Am I attacking this properly? Is this nut the key to loosening the belt tension or is there something else I should do prior to? Any ideas?
