Repeat the measuring procedure at eight points around the ring gear. Using the J 36599-A or the J 36615, turn the left and the right side differential adjuster nut sleeves out or counterclockwise one notch. Specification The difference between the backlash at all of the measuring points should not vary by more than 0. They're machined from the finest materials using modern gear grinding technology to give each set superior strength and the smoothest and most precise finish. Install the seal using the J 36366. . At that point the nut will seem tight but your pinion will still be loose.
Record the dial indicator reading. To determine the actual backlash, divide the dial indicator reading by 2. Specification The rotating torque of the drive pinion and differential assembly should be 2. Use the handy Links below to access over 40 years of Dan's product and vehicle specific Tech Notes to easily get the information you need for your vehicle's repair, maintenance, or upgrade project! Compare the new measurement to the specification listed in step 34. Tighten the bearing cap bolts to 207 Y 153 lb ft 11.
Recheck the rotating torque and adjust if necessary. Important: If the rotating torque is exceeded, the pinion will have to be removed and a new collapsible spacer installed. If the backlash is too large, decrease the backlash by turning the left differential adjuster nut out using the J-36599-A side bearing nut wrench and the right differential adjuster nut in using the J-36599-A side bearing nut wrench , 8. If the carrier case halves do not make complete contact, use the J 36599-A in order to back out the right differential adjuster nut sleeve until the differential carrier case halves make contact. Measure the rotating torque of the pinion using an inch-pound torque wrench.
Place shop towels in the vise in order to protect the differential carrier case. Refer to Differential Carrier Assembly Assemble. Tighten Tighten the differential bearing adjuster nut retainer nut bolts to 27 Y 20 lb ft. Install the pinion gear, with the inner pinion bearing and the new collapsible spacer, into the left differential carrier case half. Once it starts to compress, the required torque needed to continue tightening the nut will still be high, but reduced from the amount needed to start compression. After the backlash is set, the final bearing preload is set.
Once the bearing preload and drive pinion to ring gear backlash is within specifications, perform a gear tooth contact pattern check to ensure proper contact between the pinion and the ring gear. Recheck the rotating torque of the pinion and differential assembly and adjust, if necessary. Don't see the particular axle or drivetrain parts you need? What are you guys setting you carrier bearing preload too? If the difference between the backlash at all of the measuring points varies by more than 0. It's usually given in inch pounds. Remove the differential bearing adjuster nut retainers. I got the gears from Just differentials and they are telling me the adjusting nuts are just for setting backlash and there is no spec for the carrier bearing preload.
Refer to Adhesives, Fluids, Lubricants, and Sealers. Install the old pinion nut. Remove the old pinon nut. The cover is also equipped with a dip stick and magnetic drain plug for easy service. Tighten the nut until a few of the shaft threads show through the nut so that the washer and new pinion nut can be installed. This genuine original equipment American Axle Manufacturing Pinion Flange has a factory installed deflector with integral wear seal and wiper seal.
Tighten Tighten the pinion nut until the pinion end play is just taken up. To get an accurate torque reading, you should remove the axle shafts as the drag from your wheel bearings and brakes will adversely affect your results. Use the handy Links below to access over 40 years of Dan's product and vehicle specific Tech Notes to easily get the information you need for your vehicle's repair, maintenance, or upgrade project! Install the J-8001—1 1, 2 , the J-8001—2 3 , and the J-8001—3 4 as shown. I set it by backlash,. If the new pinion nut cannot be installed, perform the following steps in order to seat the pinion yoke onto the pinion so that the washer and new pinion nut can be installed: Remove the pinion nut washer. Certain Products, such as Warn® Hubs may be covered by additional manufacturer's warranties. Install the differential bearing adjuster nut retainer bolts.
Anyone confirm this is correct? Refer to Gear Tooth Contact Pattern Inspection. If the original bearings are to be reused, the original bearing cups must also be used. Install the bearing cap bolts. If the rotating torque of the pinion and differential assembly is not within specifications, continue to loosen the left and right side differential adjuster nut sleeves one notch at a time on each side until the rotating torque of the pinion and differential assembly is within specifications. Specification The rotating torque of the pinion should be 1. Refer to Differential Carrier Assembly Final Assembly. Ensure that the button contacts the outer edge of the pinion yoke and that the plunger is at a right angle to the pinion yoke.
Tighten Tighten the differential carrier case bolts to 47 Y 35 lb ft. Install the differential bearing adjuster nut retainers. When all end-play is gone, you have to be very careful as it will only take a small movement of the nut to go from too loose to too tight. Which I know is wrong. We carry more products and brands than we can make available on this website so give us a call or send us an email and chances are we can get what you need at a great price. Measure and record the backlash.
