I can't get the stupid bearings off the true trac no one rents out a clamshell puller Clamshell pullers are not what you need. Are you working on a used truetrac or did you install the bearings and now need to remove and adjust shims? The tool you need for carrier and pinion is this one: https://www.revolutiongear.com/product/bearing_puller If you manage to use a clamshell puller, at the very least it ruins the bearing. If you need to install and remove bearings to set your backlash, preload etc, then garb a pair of old bearings and use a dremel or similar to grind the ID of that bearing out just enough that they slide on and off. You create what is know as a “setup bearing” that way. Makes adjustments far easier. Link to comment Share on other sites More sharing options...
Jesse J Posted January 18, 2022 Author Share Posted January 18, 2022 I was under the impression the tool in the link is called a clamshell puller. Link to comment Share on other sites More sharing options...

I was thinking of the regular bearing pullers. East coast gear supply rents them but keep in mind that most shops don’t even have this tool.

ghetdjc320 Posted January 18, 2022 Share Posted January 18, 2022 So, is the truetrac used and your trying to change gears? Or did you need to pull off new bearing off of a new carrier Link to comment Share on other sites More sharing options...

Jesse J Posted January 28, 2022 Author Share Posted January 28, 2022 So there are supposed to be these shins on the outer side of the pinion to create the right preload? Front doesn’t have them :/ also does the oil slinger go behind the rear bearing if so I forgot to put it on before I put my bearings and seals in so Isbella there a way to get that in without wrecking the seals? I assume not Link to comment Share on other sites More sharing options...

I assume not Oil slinger typically goes just under pinion head and it (along with shims) set your pinion depth. Preload is handled with shims on the other side. Both adjustments are 100% critical.

Front doesn’t have them :/ The factory used thick cast iron spacers for diff bearing preload. When you're building hundreds of thousands of axles, you can make your spacers the correct size, you don't need to stack shims. Sometimes they're under the bearing cone on the carrier, sometimes they're on the outside of the bearing, between the bearing and axle housing.

Jesse J Posted January 28, 2022 Author Share Posted January 28, 2022 where do I buy preload shims? also I need more smaller options of carrier shims than they gave me where might one find those? Link to comment Share on other sites More sharing options...

Preload shims come in the master install kit. They should have more than enough shims. Remember, set your depth first. Here is a handy little diagram. Make sure that the oil slinger is under the pinion head before the first pressed on bearing. Here is a super handy and comprehensive step by step guide I’ve used in the past: http://www.billavista.com/tech/Articles/Gear_Setup_Bible/index.html Link to comment Share on other sites More sharing options...
Jesse J Posted January 30, 2022 Author Share Posted January 30, 2022 Thanks for the very helpful link read the entire thing. my kit still didnt come with pinion bearing preload shims and idk where to get them from. Link to comment Share on other sites More sharing options...
Jesse J Posted January 30, 2022 Author Share Posted January 30, 2022 also I have bent several of my carrier shims and need more and new ones. having trouble finding part numbers Link to comment Share on other sites More sharing options...

Your shims should be going UNDER your carrier bearings. It’s so much easier to do this with “setup bearings”. You can also make your own setup bearing by lightly grinding the inside of a used set of bearing until they are able to slip on and off of the carrier. Set your backlash, pinion depth, then find the “zero” lash point of the carrier and add in however many thousandths of preload the specs call for. Add the equal amount of shims to each side then press on a new set of bearings. Be careful installing your seals and make sure to add some assembly lube to all of them.

watchamakalit Posted February 3, 2022 Share Posted February 3, 2022 Without the seal. Setup everything first. Seal goes on on final assembly. Link to comment Share on other sites More sharing options...
