What is the torque on pinion nut?
110-125 ft/lbs
TORQUE SPECS: Pinion Nut 110-125 ft/lbs unless higher torque required per step #6 above.
What is the torque on a Dana 44 pinion nut?
| Axle Type | Cover Bolts FT. LBS. | Pinion Nut FT. LBS. |
|---|---|---|
| Dana 44 | 30-40 | 200-220 |
| Dana 60 | 30-40 | 240-300 |
| Dana 70 | 30-40 | 220-280 |
| Dana 80 | 35 | 470 |
How tight should pinion be?
Be careful a quarter turn past optimum is way too tight. You only want 12-20 in. lbs of torque on the free spinning pinion. If you go too tight, the only thing to do is take it apart and crush a new sleeve.
Can you over tighten pinion nut?
Once you crush a crush sleeve, you cannot “uncrush it”. If you overtighten the pinion nut, you need to remove the pinion and replace the crush sleeve.
How do you set a pinion preload without a torque wrench?
Cut off an exceptionally large piece of duct tape. Find an equally long piece of strong rope and wrap the duct tape around the rope. Position the rope around the pinion nut so you can pull on it to either tighten or loosen the nut, as required. It might not be fancy, but it will get the job done.
What size is the pinion nut on a Dana 44?
1 5/16″
Technical Notes: 1 5/16″ socket, 7/8″-14 thread.
How do you set pinion depth?
Pinion Depth – The distance from the face of the pinion gear to the centerline of the ring gear. This is adjusted by adding or subtracting shims to the inner pinion bearing.
How do you fix a loose pinion bearing preload?
If the preload is too loose then remove shims so that the bearings will be tighter against the races and increase the preload. If the preload is too tight then remove the pinion gear and add shims so that the bearings will not be as tight against the races.
How do you tighten a pinion bolt?
With the rear wheels off the ground tighten the nut up snug but don’t over do it. Put the torque wrench on the nut and apply force it like you are tightening the nut and note the reading as the pinion is rotating. The normal process is to check-tighten-check-tighten and so on until the preload spec is reached.
What is the spec on a pinion nut?
If you are talking about the pinion nut it is not hand tighten. The spec measures the torque required to turn the pinion gear by itself once the nut is tightened. The spec is NOT the torque applied to tighten the nut. That is whatever it takes to achieve the pinon bearing pre-load which is determined as described above.
Where does the pinion go on a Toyota 4×4?
If the CD is too short, the pinion sits too high in the case and rides more toward the toe of the ring gear. If the CD is too long, the pinion sits low and rides more toward the heel of the ring gear. Proper CD will allow the pinion to mate more evenly in the middle of the ring gear width for optimum mesh and strength.
How big is the torque cap on a pinion?
Pinion Preload (Reused) Ring Gear Backlash Ring Gear Bolt Torque Carrier Bearing Cap Bolts Chrysler 7.25″ 12 to 14 in-lbs. 6 to 7 in-lbs. .006″ to .010″ 55 ft-lbs.
What’s the difference between spec and pinion gear?
The spec measures the torque required to turn the pinion gear by itself once the nut is tightened. The spec is NOT the torque applied to tighten the nut. That is whatever it takes to achieve the pinon bearing pre-load which is determined as described above.
