me again! Done a job i've been meaning to do for a while, so this is the center of my truck
I have to use a 12 pinion on a 56 spur, even this is a little high with 18 cells now rather than 16. I cant go any lower on the pinion as it rips the teeth off the spur, plus the clutch has been getting anoying, it seems to be affected by temperature, some days it slips some its too tight and flips the truck, so really I want to go to a diff with a thick fluid, like 30k weight or something. Problem is on an 1/8th diff you have limited spur gear choice.
On the left is a 60T (i have a 56 aswell) mod one ofna gear from a 2 speed setup, on the right a gear that fits the 1/8th diff.
so i made this :)
it sits inside the gear perfect to keep it central
inside
bolted to the diff case for an airtight fit, I couldnt countersink the screws as its a bit thin.
just had to drill 4 holes in the spur to allow for the screw heads
