d44 pattern check

[souske]

Just throw the 35 back in and call it good

 

[MoparManiac]

That pattern is not acceptable.

.005-.010 sounds like a tight tolerance. I thought it was more like .007-.012.

I'd pull out .002"

 

[DoWorkXJ]

Yea trying pulling .001" to .002" out. Backlash still good?

.005-.010 sounds like a tight tolerance. I thought it was more like .007-.012.

I'd pull out .002"

.005-.008 according to the dana manual.
backlash is a little high, shimming it now.

 

[Vanimal]

backlash is at .007 again.
rechecked the pattern.
just confirming with you guys before i pull a thou or two out

 

[Vanimal]

Still at .007 backlash? For an almost perfect setup. Pull .001 out of the pinion and tighten the backlash up .001-.002. Backlash is usually .005-.010 for 44's, depending on gear vendor.

Your probably not using setup carrier bearings.

What you have now is acceptable. The pattern is centered on the face (most important) of the tooth but not heel to toe (not great but works).

yea, no setup bearings

 

[DoWorkXJ]

Yea I still think you need to pull shims. .001"-.002".

 

[Vanimal]

so i'll be back to the last pattern i posted yesterday.

 

[DoWorkXJ]

You might have to play with your backlash as well.

 

[MoparManiac]

The pattern you posted on page two looked good but I couldn't tell from the pics.

 

[Vanimal]

here's with .001 taken out. whatcha think?
backlash is at the high limit, may add a couple thou

 

[Vanimal]

still a c hair too close, huh

 

[DoWorkXJ]

still a c hair too close, huh

It is better than your last pic for sure. What is your backlash exactly? I think increasing it a tad will help.

 

[Vanimal]

.009", a little out of spec.

 

[DoWorkXJ]

.009", a little out of spec.

I think you can run with .010". IM0.

 

[Vanimal]

latest pattern, minus .001
backlash .007

 

[Vanimal]

dowork, got your pm, thanks!

does this look like the pinion is too far away now?

 

[DoWorkXJ]

dowork, got your pm, thanks!

No prob. No, I think you should try .010". Are the specs your using from the gear manufacturer? Are you torquing down your bearing caps when your checking your pattern or no?

 

[Vanimal]

im using specs from the dana manual, and i'm running a dana ring and pinion so it should be right. i dont feel comfortable going out of those specs, no offense.


i am torquing everything to specs before checking the backlash and pattern.

Are they brand new gears?
