What diff ratio??

Post by mattmac2011 »

Ok so this might seem like a dumb question but i could use a hand on working out what my ratios would be. I have an LN106 and at the moment have the rear diff out and have counted the ring gear. 35 teeth. would that give me a 3.55 ratio??? :?
Cheers.

Mark the diff and spin the pinion count how many turns you get of the axle versus the pinion.

Should be 4.33 I thought they had more than 35 teeth though.
I'm not quitting drinking, I'm retiring at the top of my game - sporting comeback likely.

why didn't you just count the pinion teeth while you where at it ??
by mem theres a couple of different pinions as well as different ring gear.

Count the crown wheel teeth.... count the pinion teeth... count both ACCURATELY... then divide the big number by the little number..... that's your diff ratio... some diffs have the numbers stamped on the edge of the crown wheel (like 10 x 37) but I don't know if the LN106 does....

My memory says that they are a 4.3 but just count the number of teeth on the crown wheel and pinion and divide the number on the crown wheel by how many is on the pinion.
That will give you your ratio.
