So ive been thinking about the OBA on the 88. When i first put the 460 in, i put the York where the factory a/c compressor used to go. While this worked well, it caused problems with the factory air intake. I figured while the front clip is off, is the perfect time to come up with a better solution.
Looking at it, there is definitely some room down where the smog pump used to be
Problem is, it would require a ton of work to the bracket to get it in there. As it sits in that pic, its laying on the frame. I considered putting it where the alt was, and moving that down as it would be easier to do
I rejected this idea as well, because i dont like having the alt down that low. So i pretty much had no choice but to see if i could build my own accessory drive bracket. So, here we go!
With the stock bracket gone, there is a ton of room
York mounting plate
Making some spacers
Main plate, roughly cut to size
York hung, plenty of clearance to frame now:
threading some bar stock
Designing the alt mount. Reusing the bushing from the OEM alt mount
Reusing the OEM tensioner bracket
CAD (cardboard aided design) for the 2nd half of the alt mount
Welding it all up
final fit on the motor
...and all done & painted!
Final install on engine:
Its a tight fit, but it looks like its going to work well. This took me a while as the little guy consumes most of my free time these days, but it worked out well because it gave me time to stand back, take it slow and make sure nothing interferes with anything else. It goes together pretty easily, no bolts in awkward places or anything like that. Hopefully it works well, but the motor wont be running any time soon, so i guess we'll have to wait until later to see it in action!
Still sorting out the belt length; guessed wrong and got one this morning that ended up too short by an inch or so, gotta return it and get one a little longer sometime during the week.
