2 questions.......
« on: July 16, 2005 - 07:13:42 PM »
Got a couple of things that I want to clear up..............first I am knee deep in harmonic balancers........Do the 383s and 440s share the same harmonic balancer?    Gonna have my rotating assembly balanced and I am sure he will need the harmonic balancer........

2.  My car is ps, pb, and A/C       again I have some pulleys that I inherited when i got the car.......Questin is simply this.......Does the crank pulley have 2 or 3 grooves?     How many grooves will the fan pulley have?
I am hoping crank is 2 grooves........I think fan is single groove, but not sure......thanks  Kevin

383  & 440 steel crank engines use the same dampers , 440 cast crank dampers are different & are thicker

2 groove crank pulleys are used for alt /waterpump & power steering , most A/C pumps use 2 belts so the crank pulley is a 4 groove piece

My SE is  A/C and PS


A/C compressor is 2 belts

PS is one belt

Water pump is one belt

Alternator is 2 belts

Crank is 4 belts

Idler pulley is one belt

Waterpump is one belt


Now that youre on the search for a 4 belt crank pulley......
The 4 groove pulley for a CAST Crank and the 4 groove pulley for a FORGED crank have DIFFERENT BOLT PATTERNS.   so watch for that.

440source.com has the part numbers and the detail you need to distiguish both.  eBay ought to have something for you.
