How is pinion depth measured?
How is pinion depth measured?
This is done by measuring the thickness of the pinion gear, and subtracting it from the mounting distance listed below. The resulting dimension is the pinion depth. If a gear is marked with a plus or minus figure, that dimension, which is thousandths of an inch, must be added to or subtracted from actual pinion depth.
How do you measure the depth of a pinion?
It is important to take note that you set the tool to 1” of travel, however the centerline of the tool actually measures 2” from the tip of the indicator when it is resting in the fixture. Next, install the “dog bone” onto the pinion gear, and hold it in place with the clamp provided with the tool.
How to calculate the pinion angle of a car?
If the angle of the rearend is steeper than that of the driveshaft, subtract the angle of the driveshaft from that of the rearend to see how much positive pinion angle you have. For example, if you have a rearend angle of 5 degrees from vertical nose up and the driveshaft is angled up at 3 degrees,…
How is the depth of a pinion nut adjusted?
Pinion gear depth is commonly adjusted by varying shim thickness on the pinion gear and bearing assembly. PINION BEARING PRELOAD.- The pinion bearing preload is frequently adjusted by torquing the pinion nut to compress a collapsible spacer.
How to use the T & D Universal pinion depth gauge?
How to use the T & D universal pinion depth gauge to measure pinion depth on all stand alone differentials that are not part of a transaxle. From the early 1960’s to modern day differentials Category Autos & Vehicles Show moreShow less Loading… AutoplayWhen autoplay is enabled, a suggested video will automatically play next. Up next
How big of a shim do I need to measure pinion depth?
My initial measurement, with a .021” thick shim installed gave me a reading of 2.462”. The ring gear had a measurement of 2.476” etched on the face. The difference between the two is .014”, so I knew that by adding .014” to my initial shim thickness of .021” I would need a .035” thick shim under the pinion bearing.
What’s the best way to measure the pinion angle?
If the driveshaft was angled upward (it would be rare to find one that isn’t) and the rearend is nose down (not always the case, so be sure you know which way its positioned), just add together the two angles you measured.
How do you calculate the pinion depth of a gear?
You must calculate the pinion depth on most OEM gear sets. You can do this by measuring the thickness of the pinion gear head and subtracting that measurement from the factory mounting distance measurement. The end result is your pinion depth.
Pinion gear depth is commonly adjusted by varying shim thickness on the pinion gear and bearing assembly. PINION BEARING PRELOAD.- The pinion bearing preload is frequently adjusted by torquing the pinion nut to compress a collapsible spacer.
