Joe is local to me. This is a small picture taken in an area called Pyeatte Draw near Payson, Arizona. The Spartan is going in the front 8" Hi-pinion of his 4Runner. |

Joe brought over the Spartan and the open 2 pinion HP 3rd. |
|
The first thing I do is mark the adjusters....1 ding here. |
|
And 2 dings for the other side. |
|
I don't have to mark the bearing cap because it has a factory brush stroke but, out of habit, I did. |
|
The electric impact sure saves time :) |
|
I did the gear install on this about 2.5 years ago. |
|
These are the "circle K" gears that I like. |
|
The cured loctite is very evident..... |
|
....but the bench grinder with the wire wheel attachment sure makes them all look brand new again. |
|
With the ring gear off now I can drive out the steel dowel. |
|
Out comes the crosspin(power pin). |
|
Remove both spiders. |
|
These are the parts we will not re-use...not even the thrust washers on the sidegears seen here. |
|
The guts have been stripped clean effectively. |
|
30 spline sidegear couplers....excellent piece of machine work. |
|
This pre-assembly measurement is not specified in the Spartan manual.... |
|
...I measured .007" on this side of the power pin and .008" on the other. |
|
The thick pieces of wire hold the pins/springs in the 2 Spartan drivers during the assembly. |
|
Put spring in pin... |
|
Pushed down all the way and insert wire. |
|
This makes the Spartan so easy to assemble in the open case. |
|
Now just wiggle everything in place. |
|
I use a couple of screwdrivers to keep the teeth in alignment.... |
|
...and pull out the wires. |
|
All 4 wires have been pulled out. |
|
Just rotate the Spartan drivers until it snaps in place and the cam holes are directly across from each other. Those 4 tiny springs sure have a lot of tension. |
|
In the Spartan manual, it does mention a center gap measurement to be performed.....145 to .170" between the Spartan drivers.... |
|
I measured about .150" on this side and .160" on the opposite side. Pass. |
|
The Spartan supplied crosspin is jiggled in place. |
|
Tap the steel dowel back down the hole. |
|
I like to use a pointy center punch to distort the round hole... |
|
The dowel will never work its way out with this obstruction in the way :) |
|
I was able to seat the ring gear with numerous hit from the rubber hammer. |
|
Red Loctite #271 on all 10 ring gear bolts. |
|
75 ft/lb on all ring gear bolts. |
|
..... |
|
75 ft/lb on the 4 long bearing cap bolts. |
|
Backlash is juggled along with the carrier bearing preload. |
|
blue medium strength loctite... |
|
... and 10 ft/lb. Notice I elected to ease up on the CBPL and 1 less notch of "tightness". |
|
This Spartan should give excellent service. |
|
Pattern check----excellent drive. |
|
Coast is smack in the middle and favors the root which is exceptional. |
