Pulleys and belts

Can anyone tell me the correct pulleys and belts for an S code with air and power steering? I need the smog pump, water pump, crank, power steering and A/C pulleys. I also know it has the two idler pulleys as well. It is a July '68 N..J. car w/ auto trans. Also a description on how the belts run. Thanks in advance to all of you who continue to be of help. Tom

Pulleys and belts


The FE Motors from 67-70 With air had:

6AA Power Steering Pump inverted pulley that ran off the OUTSIDE groove (Closet to Radiator) of the Crank Pulley Belt Routing is PS Pump STRAIGHT to Crank Pulley, around it, back to PS Pump. Cradle Bracket for PS Pump will be a C7AA, Steel Support bracket from Water Pump to Power Steering Pump will standard be 67-70 FE .

The Crank Pulley will be a stamped steel 67 -70 FE 3 Groove--Something like C8OE. Early 352, 390, 427 62-66? Pulleys are different won't work.

Alternator will be a single groove straight on pulley.

Water Pump single groove--Can't recite the number.

Alternater runs off inside groove of crank, closet to motor, Around Water Pump Pulley, around Alternater, back to crank.

Air runs off middle groove of crank, WATER PUMP PULLEY NOT INVOLVED in Air Belt Routing.

This is how we set these up with air.

Check out Bill Upham's site http://www.mansfieldmustang.com/

He has most everything in stock and everything I have purchased from him has been nice quality. You can use his on-line catalog for research or to purchase everything you need.

Good Luck

Re: Pulleys and belts

A picture is worth a thousand words. This is a 69 but routing is the same. For the smog pulley most 390/428/KRs used the C8AZ D, some late ones used the C8OZ. Both are extremely rare.

It sure helps to put the picture together with the words. Thanks for your help.
