Well I finally got around to doing the final install on my Dana 30. I used dummy bearings and what not and had everything set right with good patterns. I pressed the new bearings on and set pinion bearing preload with the correct shims. I installed the carrier and now my backlash is .004 instead of .006 like it was.
Well I'm ready to throw in the towel. I took everything back apart. Put spool back in housing and put dial indicator on it. Doesnt even have .001 runout. Dressed the back of ring gear and reinstalled and torqued. Put dial indicator on back of ring gear and measured runout. measured .002 total. reinstalled pinion and set back lash.
In SECTION 5, we have discussed the standard tooth thickness s1 and s2. In the meshing of a pair of gears, if the tooth thickness of pinion and gear were reduced by Δs1 and Δs2, they would produce a backlash of Δs1 and Δs2 in the direction of the pitch circle. Let the magnitude of Δs1 and Δs2 be 0.1., We know that α = 20 degrees, then :
The pinion gear lash is adjusted with different thickness shims placed underneath the notched nut at the drive shaft. The ring gear lash is adjusted using paper gaskets between the FD cover and the FD. ... I had to put thicker spacer behind ball bearing on cover to adjust ring gear depth engagement to get back lash right my book calls for …
You also need to turn the ring gear several revolutions in BOTH directions (clockwise & counterclockwise) to check the drive and the coast contact pattern. Below are some example of how pinion depth can effect the contact pattern on the ring gear. All patterns were achieved with with a .008 - .010 backlash.

The tip clearance should be. a) Able to take care of the thermal expansions during the operations. The gear ratio shows it to be a large gear. Our gears with ratio 222/27 ahs a diameter of more than 5m. b) Take care of the profile machiining - the root radius etc should not be damaged during hobbing the involute.
With my shim selection, I was able to add .003 to the pinion support. Move the pinion out slightly. My first shim was actually .022 thick. I am now at .025. Back lash is same about .009, the ring gear is marked .010 for …

Having it slightly towards the outside actually makes a stronger setup because you have more surface area for gear contact. If you set the pinion deeper, you are going to cause a sharp edge on the contact pattern on the left (root) side. Yukon and Standard recommend 6 to 10 thousands on the backlash for a D44.
Attached are some photos of the ring gear setup that I would like some of your opinions of the pattern. This is with a .010" to .011" of back lash (on a used set of gears). I have attached pics of both the drive and coast sides of the gears. Since this is the first ring and pinion I have set up, I just want to make sure I was getting it right.
This ball mill uses helical gears(i.e. 284 teeth girth gear with a 24 teeth pinion). Register to Reply. ... back lash. The blue contact should be evenly spread (to …
The back lash is pretty self explanatory, and I would suggest the use of a 'Super Shim' kit for the carrier bearings to help with lash adjustments. But I will say that pinion preload is the most critical.....35 'rolling' inlbs of preload. Most of the Richmond installs that I have done going to a 3.73 ratio, have required about 0.032 - 0.036 ...

red fuel. 49 posts · Joined 2014. #5 · Jul 26, 2014. mudslinger is spot on on how to check it properly. although that looks normal to me. the pinion will move more than the actual ring/pinion back lash because its taking the play out of the spider gears/ lsd also. 08 cc 2500, 6.7 deleted with efilive.

In addition, the project will ...
Remove the QC case and carrier from the left tube and reinstall the ring gear on the carrier remembering to torque the bolts correctly. Reassemble the unit and this time install 4 bolts in a square pattern on the upper tube also and tighten. This establishes the positioning to determine the pinion back lash.

Usually a good start is to reuse your old pinion shim. To adjust backlash, you change the shims on the carrier. To increase backlash, decrease the shim on the left and increase by the same amount on the right. That basically slides the carrier to the left, thereby increasing backlash. To decrease, do it the opposite way.
No. 1 – GEAR AND PINION VIBRATION. Cause A – EXCESSIVE BACKLASH. Move mill gear toward the pinion and check for proper backlash per separate instructions. Cause B – INSUFFICIENT BACKLASH. Move the mill gear away from the pinion and check for proper backlash per separate instructions. Cause C – OUT OF …
After installing the pinion shim behind pinion bearing, install in axle and tighten. Install differential case assembly with ring gear into axle. Set-up side bearing load and backlash per OEM's service manual. When setting backlash, the rule of thumb is 0.004".
Ken. Pinion runout, as HdMd said, is the wobble in the shaft the gear rides on...so as the shaft wobbles, the gear will wobble as well. What this means is that in one area of the gear's mating rotation, the gears may bind tightly while in other positions the gear mating (gear lash) will be excessively loose. This makes for a noisey gear drive.
1-it started out within spec. 2-normal for mileage and maintenance done. 3-you can reshim to adjust backlash, however you MUST check your pattern and make sure your pinion is still engaging properly (toe/heel and …
