What is the position of pinion?
What is the position of pinion?
The pinion gear can also be positioned in the centre to obtain longer steering rod travel. Pinion gear located outside the vehicle centre (on the left on left-hand drive and on the right on right-hand drive) and tie rod joints screwed into the sides of the steering rack (side take-off).
What should the preload torque be on a pinion?
Tighten the nut until a slight end float can be felt on the pinion. Attach the pinion preload gauge to the drive flange and measure the oil seal drag (usually around 0.6 Nm). To this oil sealed preload drag add the bearing preload torque of 2.2.–3.0 Nm.
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 does pressure mean on a pinion bearing?
By pressure, it means preload. Turning the nuts in a pinion gear, it crushes the spacer to obtain a “specific” preload. As you’ve noticed, to get a specific preload, you need to measure the torque. The methods to make that adjustment without a torque wrench are the things that we’ll discuss right below:
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.

How much torque do you need for a pinion nut?
Developing 200 + lbs of torque is no problem. Holding the companion flange in place while you are doing it certainly is. The tool companies make a jig that you bolt to the companion flange that allows you to counter torque while you tighten the nut but I am guessing you don’t have one of those.
How to calculate the torque of a rack and pinion?
Torque. This is what the pinion sees and is simply tangential force * arm (radius pinion) [in Nm]. In this case F 2T = 2 * T 2B / d. Safety factor. Apex recommends a safety factor of at least 2 for horizontal and 3 for vertical drives. Friction coefficient. How heavy – or light – does the system run? A widely used value is 0.1 or 0.15.
