Serpentine kits for perkins 4.236

[evm1024]

I've been pondering putting a serpentine belt on my Perkins 4.236 but I've been running into some conflicting info.

Currently I have a 1/2" vee driving a balmar 91-100/MC-612 and push 80 amps to a LiFePO4 house bank.

I've been looking at the Balmar at-165 with a 10 groove pulley. Looking around I do not see a 4.236 serpentine pulley set listed on the Balmar site. They appear to be around but there is not much info.

I do find 6 groove pulleys for the 4.236....

So the question is have you installed a Balmar at-165 and 10 groove kit on your 4.236? Where did you get it? What issues were there in installing it?

And in a more general way - Why are 4.107/8 kits listed and not 4.236?

Thanks!
