Might be the photo angle, if im understanding you correctly. Truck was bought like this and im going to guess its been like this (belt length) for years.
I've got other angles on my thread in the members projects page under LULU. On my phone now it doesnt want to let me grab the pic links and paste across.
Oil is just absolutely everywhere and on everything! One thing at a time and we'll get there. As mentioned by another member earlier on the different belt lengths i'll be measuring my alt pully to make sure im getting the right belt.
What looks like the rubber between the tensioner is all broken up too, i guess the oil has wrecked that. Being soo caked just a quick blast with degreaser isnt going to cut it. New part will go on so one last thing to clean hey!
