Drive belt

[engineman76 0]

Need some help fellows. I am trying to find the right drive belt for my WH 8 four speed. Manual parts # is 7374 but that does not help me. Can someone give me a length or the proper belt to purchase.

[C-Series14 15]

Part number is 7473

7473 HB/5L 81.95

There is a lube and belt chart somewhere...I thought! I have typed this belt size a million times, alot of 8-speeds out there!!!

Oh, and I see it is your first post... :USA:

Thanks for the Welcome guys. It is a pleasure to be a member of this forum. The information on the belt is very helpful. If I am reading ist right the belt is a "B" belt 81.95 inches long.

I hope I am replying correctly. Please let me know if not.

Thanks again

The cross reference to Gates is # 6982 and to NAPA is 5L820W. Remember these are FHP belts and not automotive belts. I personally prefer the OEM belts myself.

Blueknightbob sent me this several years ago:

Napa and Gates belts use a formula to get the right part number.

NAPA

The first part of the number is 4L = 1/2" wide

The first part of the number is 5L = 5/8" wide

The last part is the length. 700W = 70" long

Napa 4L-700W is a 1/2" wide X 70" long

Napa 5L-700W is a 5/8" wide X 70" long

More examples:

Napa number 4L-720W is a 1/2" wide X 72" long

The "W" after the part number means heavy duty.

Gates

The first part of the number is the width. 68 = 1/2"

The last part of the number is the length. 70 = 70"

Gates number 6870 is a 1/2" wide X 70" long

Gates number 6970 is a 5/8" wide X 70" long

Gates number 6883 is a 1/2" wide X 83" long

More examples:

Gates number 6892 is a 1/2" X 92" long

Gates number 6946 IS A 5/8" x 46" long

So if the belt is 1/2' wide by 72" long: Napa number is 4L-720W

and the Gates number is 6872
