Cost cutting front 5.29 install
(19 low res pics loading)
FEB 14 2005
Intro:: Shawn was looking to have some good 529 gears installed but did
not have a lot of extra money so we consulted and it was decided to
re-use the old bearings as long as they were still servicable. We could
also get away with a simple crush sleeve in the front. I already know
that Shawn is very hard on his equipment so I decided to use US GEAR
529's. The rear install would get the solid collar treatment.
We did the front first.
Started by marking the caps.....
Just using the dial indicator to
check run-out. I had less than .002".
The ring gear bolts were loaded with blue
Loctite and 70 ft/lb. The carrier bearing
on the ring gear side was a loose fit but
sleeve lock compound took care of that.
The old pinion bearings passed
inspection and will be re-used.
Those wide shims on the left leave no
room for fingers to grip if/when the
pinion bearing has to be re-moved for
a re-shim....the solution is to trim
them down like the ones on the right.
I used a pair of pliers and a thin
cutting wheel to trim off the edges.
A crush sleeve will be used as the last
process so for now it's assembled with no
crush at all and snug the nut down til
about 4 in/lb of drag is measured.
I like to use anti-seize on the bearing
adjuster threads. Easier to overcome all
that thread resistance when doing the
final 90 ft/lb carrier bearing pre-load.
The backlash is about .010" here and the
carrier bearings are very tight. To get
a readable pattern, I wedge a crowbar
against the ring-gear and rotate the
pinion flange. Loose carrier bearings
would cause false readings so tight
counts. My support stand for the 3rd
member is crude but will "evolve"
If the pinion bearings were new, I probably
would use 97~100 thou for the pinion shim.....
but used bearings change that. I chose .105"
and this is a good pattern 1st time.
coast side .105"
This is the reason why pinion teeth generally
don't break first(in a proper gear install)....
this is where the tooth on the ring itself ends.
It's still about 1/4" from the heel end....it's
the heel end that sees all the load during
Load the new crush sleeve up.....
The blue RTV helps the new seal tap on nicely.
A hammer can ruin a seal. Don't forget to apply
some grease/gear-oil to the rubber seal surfaces.
A very simple tool for locking the yoke in
place. Blue Locktite is on the re-used nut.
I mentioned it on one of the internet 4x4
boards that I could crush a sleeve with 2
fingers so I did...and continued crushing
it with 2 fingers until the spec was reached.
Just wanted to show that it's not that hard
to crush those things. The blue Loctite sort
of acts like a thread lubricant anyways.
These are used bearings so I did not want
to see more than 6 in/lb of pinion pre-load.
I couldn't resist....Even though there is
Loctite on it, I had to spot MIG it. :)
With it all buttoned up, I made one more drive
pattern check with the .007" backlash....looks great.
