Title: 1972 MCI 5B blower belt
Post by: Jsrcaptain on April 24, 2021, 11:04:09 AM
I see that the blower belt, the long one, on my MCI 5B will not clear the lower crank pulley. The rear bumper frame is too close to the engine. I hate to try to pull the rear frame loose, but I can't see any alternative.
Does anybody else have this problem or a solution?

You might not have to remove the bumper/frame completely. Just loosen it enough to make room for the belt.

     Hi.

           Try turning the blower belt side ways (twisted) and put the belt on the

            engine first.  It worked for me.

Put a straight edge up against the bumper, not uncommon for them to be bent inward from careless use of pushing mules in the shop, or a minor collision on the street.

Remove, straighten, or lean it outward to facilitate the next time...

Happy coaching!

The good thing is that a belt will last 2 or 300,000 miles.

If you buy a good automotive belt,the ones from ACE last as long as a snow ball in hell but they are cheaper lol

Thanks for the ideas. The PO hit something every time he backed up I think. Makes sense that the frame and bumper are  bent. Maybe I need to jump forward 20 feet with a 10 foot chain on the bumper. Just kidding.
I'll be taking the bumper off anyways because the crank pulley is in bad shape. It looks like it's been buried for 20 years. Super rusted and pitted. The lip was broken off and someone stick welded it back on. Reminds me of an old farm tractor. Repaired with whatever was laying around.
Any ideas for locating a new/used pulley?

P.S. Already bought the belt from Luke.

Thanks

Those pulleys are hard to find without pieces missing you can use brass and do a fair job on 1

I was able to get a small jack in so I could push against the bumper and as Cliff said I cut the old one off and with Dave C's help got the new one back on. Some how Dave roiled the new one in.
