Then use a pry bar or large screwdriver to hold the bottom of the ring gear while using an end wrench to rotate out one of the bolts holding the ring gear onto the differential case. Sadly, these sometimes do not come with a magnetic plug. Has anyone had any problems with the plastic cover? If not, definately less than 25 ft-lbs makes sense. I would suggest replacing the composite cover with a stamped steel one while your are at it. Again, this is probably overkill, but it is easier to change it in my garage than on the trail in the mud.
So I backed off to 10 ft-lbs and left it. Chrysler Axles - Gear Setup Torque and Backlash Specs: Pinion Preload New Pinion Preload Reused Ring Gear Backlash Ring Gear Bolt Torque Carrier Bearing Cap Bolts 12 to 14 in-lbs. Do this by taking off the pinion flange holder and using your inch-pound beam style torque wrench. Do this right and have a happy ever after with your 8. In most cases, when rebuilding a differential back to stock you can reuse the original pinion shim without having to measure for pinion depth.
Repeat until desired torque is reached. If you put too much compound on the ring gear teeth as shown in the picture you may have to work it back and forth a few times to get a clear pattern. However, the metal cover uses different bolts than the composite cover. Data is accurate to the best of our knowledge through 2013 and is offered as-is with no guarantee. Data is accurate to the best of our knowledge through 2013 and is offered as-is with no guarantee.
Even though this is a complete rebuild, I still have the habit of measuring the remaining pinion threads as a reference and taking a sample of the old gear oil. Then the 25-35 ft-lbs makes sense. This rebuild was performed on a 2006 F150 Crew Cab 4×4 with a 9. Install the new inner and outer pinion bearing races using a bearing race installer tool. . Ring gear set up data is ©Copyright Crawlpedia. Ring gear set up data is ©Copyright Crawlpedia.
The differential was full of metal particles and burnt gear oil. Install the pinion seal I prefer to coat the outer edge with high temp silicone before installing it making sure to re-install the oil slinger first. As far as frequency of changing I think the haynes manual has this listed under the maintenance section. The pinion nut is a lock-nut so it should be replaced any time it is removed. I have never had a leaking type problem. Remove the differential cover making sure to have a drain pan underneath to catch the old gear oil.
A certain pressure -- or preload -- on the pinion bearing and spacer must be established. Mar 23, 2012 Heres the diagram and specs for the cylinder head and also i have enclosed the torque specs for the intake and its tightening sequence, good luck and hope this is helpful, have a good day. Torque: 30 Nm 22 ft-lbs. A new billet aluminum one seems safer, but quite expensive. Remember, heat is the new gears 1 enemy so it is wise not to place a heavy load on the new gears for at least 500 miles e. You need a beam style inch-pound torque wrench.
Yes, it's overkill, but I'd rather not have any leaks. As for verifying the correct teeth pattern, start by applying marking compound to at least 4 consecutive teeth on both sides of each tooth. Originally Posted by norvelplagbao52 1993 saturn sl2 1. A picture of using a dial indicator was shown early in this article and is easy to read as long as you remember your readings are in thousandths. Shim install tools work best but a brass drift works well also. Since the bolts that hold it in if that is what you asking about are not a bearing adjustment, you can go with a generic torque based on bolt size. One of the best indicators of a good pattern is if the pattern position is centered between the face top of each tooth or top land and the flank base of each tooth or root.
There are two types of spacers, collapsible, and solid. Mark Use a Gasket I use a gasket between my cover and the rear end. Once it initially breaks free you can usually pull it out by hand without further using the tools. If you go above 30, disassemble and start over with a new crush sleeve. You should not over tighten this nut, as it could result in pinion bearing damage.
I broke my composite cover when I backed into a rock, the billet aluminum ones will do the same thing although not as easily. All preload values are with a new oil seal installed in the pinion retainer. Then, rotate the pinion yoke while applying light drag to the ring gear until the painted gears come in contact with the pinion. Repeat this process until you see 20-30 inch-pounds of torque required to get the pinion to turn. A couple things: coat the inner and outer pinion bearings in gear oil and coat the inside lip of the pinion seal with Vaseline before installing the pinion and pinion flange. It is available at Napa. The minimum torque is 170 foot-pounds.
This is done by tightening the pinion nut to a minimum torque value, then attempting to turn the pinion nut and reading the amount of torque needed to turn it through several revolutions. I'd rather do it myself so I know exactly what I'm getting. Step 2 tighten an additional 95 degrees. At this time it is wise to measure the ring and pinion gear backlash as shown in the bottom right picture. I prefer to use an impact wrench until the bearings are seated and there is no endplay.
