Gear pattern pics... should I run it?

[garydan]

So, my first time setting up gears. I've gotten the backlash within specs, and here is my first pattern. These are used gears. From what I've read and seen this pattern looks really good. What do you think?

I have no clue but good job

Thanks... Finally got around to installing them

The coast is absolutely perfect. Drive looks alright but I would say since theyre used run it.

Coast side is a little too deep, drive side is almost impossible to read (though my best guess is it's deep too). Used gears can be tough to read the pattern on, are you putting lots of pressure on the ring gear as you spin the pinion to take a pattern?

Coast side is too deep? Its dead center and looks perfect to me

Lots of pressure. Wife was on the brakes.

Doesn't look like an oval to me, looks offset to the root of the teeth, IMO a couple thousandths too deep. The drive side really didn't get a good impression of the pattern and sometimes that's how it is with used gears.

I'm lost

It is too deep doesn't need to come up much but a little

 

[garydan]

How about this?

I put a tool in there to better see where the base of the tooth is. To tell the truth, I don't want to mess with the pinion depth right now unless I really have to. I'm running the same shim pack that these gears were installed with in the old axle. I realize there are manufacturing tolerances in the housing... but should I just run this or do I really need to start looking into new shims? I could also run the shim that this axle had, it was a single shim. I don't have the tools to measure them.


See the right side of this picture. I don't see why I would want to raise that pattern any more.

And taken at that angle the pinion is too far out and the coast is indeed too deep

The shim pack that is installed came with two thin shims. So try removing one?

What kinda axle is it cause 14b FFs are opposite all others in this regard.

It is a 14FF. I think I actually have to INCREASE the shim here then.

No if I remember correctly increasing the shims between the pinion housing and the axle housing will pull the pinion out. So you want to take shims out to get the pinion further into the ring.

What confuses me is that the coast side is centered perfectly.

And so is the woes of used gears. Drive side is more important in the rear...

This is what I'm working with:

And yet.. when setting up used gears. I'm supposed to focus on the coast side.
