Here's a shot of Brian on trail #42 in the Phoenix, AZ area.
|
|
Brian is local to me and brings over the RD01 ARB Locker. A new master kit/solid collar and quality 529 8" gears are going in the 4 cylinder carrier. |
|
This model has been dis-continued and is being replaced by the RD23 model. The RD01 uses 4 cylinder bearings and a "captured" o-ring seal housing(ours had the RD23 style seal housing). The newer RD23 is a semi-floating design and also uses V6 dimensioned bearings. |
|
I had to take a peek inside.... |
|
well made... |
|
... |
|
excellent machine work. |
|
I started by tapping in the pinion races. These "harbor freight chisels" are just mild steel so they're safe to use for this application. |
|
Red loctite and 75 ft/lbs all the way around. |
|
Press the carrier bearings on and line up the "adjuster nut" |
|
tighten up the cap bolts finger tight... |
|
Apply some pressure with the rag and turn the ring gear back and forth 3 times... |
|
082 is a little too deep. |
|
coast agrees |
|
This means the carrier has to be broken down all the way. Press the pinion out to prevent damage to the outer pinion race. |
|
Press the inner pinion bearing off to access the shims... |
|
Remove 3 thou and assemble the .079" shim pack... |
|
Very acceptable. |
|
Good. |
|
Using a hammer to equalize the bearing tension... |
|
Key to long gear life and maximum strength is maximum carrier bearing pre-loading. |
|
Click goes the 150 ft/lb torque wrench. Actual pre-load as measured in earlier tests was 15 in/lb on the bearings themselves. |
|
The meat of the gear install is done. Time to drill (7/16" drill bit) and tap with a 1/4 NPT tap. |
|
Liquid PTFE thread sealant was used on the pipe thread to keep the gear oil in. |
|
The seal housing with the 2 o-rings must be carefully wiggled on with lots of gear oil. |
|
Having a service loop is probably a good thing. The copper tubing forms very easy. |
|
... |
|
I was able to check clearances using the dummy cover I have. Lots of room for the copper line. |
|
The retainer clip easily goes in place. |
|
Loctite the Toyota tab in place. |
|
A quick double-check to verify 80 ft/lb on the cap bolts. |
|
The fat o-rings get plenty of gear oil. |
|
Make sure to screw on the correct side. |
|
45~50 inch/pounds feels about right for a good seal. |
|
With a new seal installed and clean threads, the original Toyota flange is installed. |
|
Ready to install. :) |
