Reading Pinion Depth Number

[IZwack]

I'm trying to read the pinion depth number on my pinion gear and I am not 100% sure exactly what it is.
Its either -88 or 188.

Right now I'm leaning towards -88 because 188 is almost two-tenths of an inch and thats a tad high for the difference between the nominal distance and this gear-set’s ideal distance. But then again, whoever at Yukon engraved these numbers onto the pinion has a leaning handwriting and it could be 188.

What do you guys think .. -88 or 188?

I also tried to look for a support phone number on Yukon's website and on the "Installation Kit Instructions" pamphlet but couldnt find any

My dana 44 gears that I took out on the pinion says +3 on the top and then the bottom says 677. Thats the most I can help you out on.

You might try calling Randy's Ring and Pinion. From what I understand they own Yukon.

Okay for future readers trying to set up a Yukon Ring and Pinion, the number inscribed onto the pinion gear is not the depth anymore.

I called Randy's Ring and Pinion (as RockRanger suggested ) and they suggested a starting pinion shim stack of .042" for a Yukon 5.13 Dana 44 axle.

So what are the numbers that are on there then?
