8.1 Volvo Penta serpentine belt
Hey everyone. Just thought I’d post some info on my serpentine belt. Part no. on original belt was 3861034. New part no. is 21132390 ( apparently). I had trouble finding one and needed it same day, also didn’t want to pay for Volvo name. I pulled belt off my boat. Marked with marker on belt and on a long board. Then rolled belt along board until my mark on belt was back on the board after one revolution. 91.875” is what I came up with. Went to Dayco website.
5060915 - 91.54”
5060918 - 91.75”
5060910 - 91.0”
All 6 rib, 13/16” wide and .17” thick.
Took all 3 numbers to local parts store. They cross referenced it with a Gates premium belt K060915. See any correlation? $50 and out the door. Put new belt on my 8.1 Perfect fit!!! It is actually a little smaller then original, but the belt tensioner had no problem handling it.
