Alright gearheads????????

[NYLES]

Old pinion is marked +2 New pinion is marked 2.625 ?????

I dont understand!!!!!!!

 

[needabronco]

I believe it refers to the pinion spacing being 'positive 2.625 thousanths of an inch. Meaning add that many shims. I'm probably wrong, it's been a year since I set up gears...

 

[NYLES]

Gearheads??? IM confused!

Old pinion is marked +2 new pinion is marked 2.625

I dont understand!!!

Old sims measure .002

 

[JWMcCrary]

I measure the thickness of the shims that came out and start with that.

 

[NYLES]

.002 old shims but thats a big diff in 2.625

Your right but dont see where they getting the 2.625 from?

 

[NYLES]

let me go look for more #'s aint seen any but think there some stamped on the shaft it self.....these just dont add up

 

[NYLES]

Nothing else except the set #

I'm guessing this is a Dana 44 gear set.

2.625 is the nominal pinion depth. If there is no +/- I'd guess the new gear is a "0". According to my Ford shop manual, you should add another .002 shim to the original stack to get it in the ballpark with the new pinion.

As mentioned above, the +2 indicates that the pinion is .002" oversized (careful, if there is an "m", its metric). Machining can vary, so they indicate by how much on each one.. You will need to subtract .002 to your pinion depth measurement when installing this particular pinion.

The 2.65 should mean the ratio.

Take a look here.. Apparently 2.625 is your nominal reading. I've never set one up that particular way..

well put it in with what was in it shim wise using the setup bearing....feels good! guess all I can do is set it all up read the paint and adj till its right then go back tear it all apart put back together and use the reg bearings and races....see how it goes!

This a PITA!!!!!!!!!

 

[NYLES]

BTW yukon book says start with what was in it!

 

[NYLES]

Ive never set one up at all....so going to put it all together using setup bearings and races adj till Im happy then tear it down put new bearings and and run it...bout all I know to do! might be awhile!

 

[HGM]

Well, the best part of it is that its only a front axle.. Even set up badly, they can last for years since they dont get as much use as a rear ;D ...

Seriously, good luck with it. That link I posted has some good info if you havent got enough..

 

[JWMcCrary]

This a PITA!!!!!!!!!

Yep it is.
I have learned to just pull the axle and put it across 2 saw horses, in the end for me it's faster and a lot less stressful, I'm too old and fat to crawl around under there for something that takes that much precision.

That's exactly how you need to do it IMO. I could be wrong but without a pinion depth tool I don't think those numbers you are reading do you much good. Take the shims from your existing setup, set it up using them and the setup bearings/race, odds are you will have to add or remove a few shims to get the preload on the bearings, from there move shims from one side to the other until you get the backlash in spec, run a pattern and see what you have, odds are the pinion will need to move in or out so you just add or remove shims from behind the setup race, reset backlash by moving shims one side to the other on carrier, run pattern, repeat etc until you are happy with it. Sounds a hell of lot easier than it is though. Use your old nut on the pinion until you are ready for the final assembly.

well had .004 backlash opened it up had too much moved shim now at ,002 mayby Ill move the right one after I eat...then tear it apart put back for good....have this done by daylight......haha

All good info.. Also, if u dont need a deadblow to reinstall the carrier on final assembly, its not tight enough
