Need 2 convert alt. v belt on 305 Chevy to serpentine.....crank pulley only. Leave other belts as is.?

Question

What's needed from what car in junk yard?
Not asking for a complete pulley change over...........just the crank pulley that drives the alternator. Tensioner issue is resolved.
Need help to determine what's needed. Existing crank pulley set up has 3 "V" groove set up.
I need crank pulley set up with serpentine (front) and 2 "V" groove to follow.
Thank you.

Answer 1

best way is find the stock mid 80s setup. sounds just exactly like what you want. smaller (4 rib or maybe it was a 5 rib) serp type belt for the alternator and then V belts for everything else. saw them on 85-6-7 or so trucks and iirc a camaro too. good set up. i would grab one if i found it, but for now i will just stay V.

edit - to answer i think just crank, water pump and alt pulleys will be needed. if possible i would grab it all to be safe...that V crap is a dime a dozen anymore.

Answer 2

Sounds like your after more amperage capacity. Some good fixes include adding a second alternator to the accessory drive system. Other,less popular options include high amp alternator replacement. What is cheap and effective is to oversize the belt width and the quality of the belt to the alt. Adding better ,and more numerous,ground wires can help imminsely. Remember that the quality of the battery it's-self can have a huge impact on system efficientcy .Any battery that continually draws 6+amps is a poorly designed battery-a battery that is designed to destroy your alternator! Wet weather belt slippage can be overcome with belt dressing at regular intervals.

Answer 3

I don't think anything like that is made. A serpentine belt generally drives multiple accessories. You could just change the pulley on the alternator to work with the v belt.

Answer 4

You are asking for a special set up from how I read your question which will need a special set up as well. You will have to find what you are looking for in the junk yard and take what you need.
