Re: Gear Ratio? Power-lok?

[Howard R Pletcher <n9ads@domain.elided>]

The 9xxx xx's do include the axle ratio along with the part number of
every piece down to the nuts and bolts making up the axle, but only if
you've got the complete IH Specs system to refer to to find out what the
9xxx xx means.   But if 4.27 was printed on the lineset, that's what the
9xxx xx will end up telling you.

Actually you've got the best way to tell what you've really got right at
hand--look for the metal tag under one of the diff cover bolts that will
have the number or ring and pinion teeth and the resulting ratio stamped
into it.  

If this is missing, just turn the input shaft to the diff and count the
number of turns necessary to get one revolution of the axle shafts.
(Assuming that this is a Power-Lok and both turn together.  If they don't
turn together, the best thing is to hold one stationary and count the
input turns for TWO revs. of the other shaft).  For more accuracy, you
might want to go for 5 or 10 revs of the axle shafts and then divide the
input count by that number.  

And as a last resort, you can pull the cover and count the number of
teeth on the two gears and divide.

14028 is a Power-Lok (or Track-Loc) code.  The lineset should say this
also.
