how to set pinion bearing preload without torque wrench

lbs.) Using a suitable tool to hold the pinion flange and remove the pinion nut 5. So caps snug, set backlash, torque roll adjusters and then torque caps. This is adjusted by adding or subtracting shims located between pinion bearings (more shim = less preload) alternatively set by tightening nut with a crush sleeve in place, collapsing it until desired preload is achieved. Either use short controlled blasts with impact wrench or turn the pinion nut a small amount using the rachet/pipe wrench combo. We talk about pinion depth and R&P backlash, but the other important setting is rarely talked about, that of carrier bearing preload. 60 ft-lbs. d. Use the old pinion nut to secure the yoke and tighten to obtain the factory specified preload. Pinion Preload is verified by rotating the pinion with an inch lb. 9. lbs.) Just remember what Tim posted about going slow. Pinion Preload (New) Pinion Preload (Reused) Ring Gear Backlash: Ring Gear Bolt Torque: Carrier Bearing Cap Bolts : AAM 9.25" 15 to 25 in-lbs. According to the Dana literature 20-40 in.lb. Too little preload will cause the carrier to move back and forth. Sign up for our eNewsletter now to stay in-the-know. The pinion preload will be zero until the bearings contact the races but will then increase very quickly. I always set pinion preload by "feel", Im doing an 8.8 now and I decided to buy a good inch pound torque wrench. Ford 8" IRS: 14 to 19 in-lbs. Make sure pinion bearing cups are properly seated in their bores. Keep this up until you have reached the pinion preload torque specified in the instructions with your kit. Most are 1/4 drive so you will probably have to have a couple adapters to get to your socket size. The risk of going back with torque as low as 55lb ft is that it may allow the flange or the front pinion bearing race to back off of the pinion gear a little and reduce preload once you start driving again. My question is how can I set the preload in the car with the exhaust pipes surrounding the pinion nut? Powered by vBulletin® Version 4.2.5 Yes some people can feel the rotating force it takes to rotate the pinion gear however there is not a lot of difference in the amount the nut turns to go from the 15"/lb to the 25"/lb and then to have the bearings a little too tight. second time ever doing gears, first was the rear end and it turned out ok... having a little trouble here. To find out more about the categories of personal information collected and the purposes for which such information will be used, please refer to our privacy policy. Is there a ghetto way to find the correct pinion depth shim without pressing on and off the bearing trying different shims til I find the right one? The pinion bearing preload is related to the amount of force the pinion nut exerts on the pinion and its bearings. so as not to overload the bearings. browsing data or IP addresses) and use cookies or other identifiers, which are necessary for its functioning and required to achieve the purposes illustrated in the cookie policy. Tighten the pinion nut, rotating the pinion occasionally to make sure the cone and roller bearings are seating properly. © 2020 Copyright Practicalmachinist.com. Never overtighten (exceed the preload). Preload The Pinion bearings and Carrier bearings run a little tight, similar to the way a wheel bearing should be "loaded". This is adjusted by adding or subtracting shims located between pinion bearings (more shim = less preload) alternatively set by tightening nut with a crush sleeve in place, collapsing it until desired preload is achieved. To measure and adjust drive pinion preload, follow the steps in Skill Drill 26-18: 1 Reinstall the pinion into the housing with a new bearing, making sure to install the crush sleeve, if equipped. It is perfectly normal to have 150-200 ft lbs of torque on the side adjusters. When installing the carrier, the same adjusters or shims that are used to adjust the backlash are also used to set the carrier bearing preload.
