Josh is from Las Vegas, Nevada and was getting a rhythmic thud-thud-thud while de-accelerating only. Josh pulls the 3rd, sees the damage, and sends it my way. A call to PORC had a PRECISION 488 gear accompanied by a model 1620 Lockrite on its way to me. |
The new gears came inside a real PRECISION yellow box...even had PG molded into the styrofoam in this picture but the symbol on the ring gear gave it away as US GEAR. US GEAR is also a very good gear. |
8 springs,2 couplers, and 2 spacers makes up the V6 Lockrite. |
This install will see a new master kit and solid collar. |
The carrier is cleaned and the new races are pressed in. |
The new pinion was installed using a .239" shim. |
.050" shimming was perfect for the V6 solid collar as that resulted in 14 in/lb of pinion pre-load. |
Now to split the case and install the Lockrite. |
... |
Thick grease keeps the pins in place while I flip it. |
... |
With no bolts in the case yet, the springs keep the case halves about 1/16" apart. |
Before tightening the bolts, probably a good idea to visually make sure the sidegear teeth are lined up on the coupler correctly. |
45 foot-pounds.... |
I saw some cosmetic damage to the case from the broken teeth getting caught up so I checked the ring mounting surface for run-out. I saw about 3 thou so I was ok with that. |
No tapping this ring gear on with my hammer of persuasion...I had to use my light-duty press. This tool is a "must have" for the type of work I do. |
Good pattern. Competition style pattern(favoring the toe). |
coast is good. |
I often eyeball the drive side on the pinion itself as another check. |
This is my torque wrench interface....it makes it so much easier to get the target 150 ft/lb on the carrier bearings. |
Putting my gut into it... |
