1 XD Aussie Locker XD Installation Supplement Dana 35 Ford TTB Thank you for your purchase of the XD Aussie Locker for Dana 35 Ford TTB The following installation review is from username Wanderer on the RRORC Forum, edited by Torq-Masters: Aussie Locker Install writeup AUSSIELOCKER for FORD Twin Traction Beam Dana 35 Model # Upon receiving the AussieLocker #13527 I was surprised by the overall size and weight of the unit. It appeared to be very well designed and thought out, it was heavier than I had anticipated, a very good sign it would withstand the punishment I wanted to subject it to. I had 2 spare carriers and housings for the ttb35 and decided to discover once and for all if there was a difference in the carriers from the 3.27 and the 3.73 (some said there was a difference). I am here to confirm that there is no difference in the carriers when it comes to installing the Aussie Locker. The only difference between the carrier is in the machined surface for the ring gear only.

2 The install was pretty straightforward. Follow manufactures instructions for removing your carrier/housing and set it on your workbench. Remove the carrier from the housing (remember to mark the bearing caps and shims for orientation and left or right side),remove the spider and side gears, saving the shims from under the side gears. Install the shims from the side gears under the axle gears. Install one set of the axle gears, spacers and cam gears onto the side of the case with the ring gear. Next install the axle gear on the open side of the carrier, then the spacer and cam gear (mine fit without any grinding on the carrier at all but some may require a little clearancing of the window. DIFFERENCE FROM MANUFACTURER INSTRUCTIONS!!! DO NOT INSTALL FACTORY C CLIP!!-see Below At this stage of the install I discovered that its best to go ahead and align the cam gears with the cross pin and install the cross pin into the carrier (you will have to take a screwdriver and slide the upper spacer out of the way). This makes it easier than to try to install the pins and get the cam gears to spin in the carrier. It takes a bit of fiddling but should be possible for you to do without having to grind on the sides of the carrier. I then installed the pins with the recess oriented towards the open side of the spring groove slid the pins into place and installed the springs. Then I flipped the carrier over and did the same for the other side. I checked my clearances and everything fell within the Mine was.150

3 I then reinstalled the carrier into the housing and torque to manufactures specs. C-CLIP ELIMINATOR. The factory C-CLIP in this axle does not fit within the spacer cup. I tested this and had to disassemble the locker with it installed and it was VERY difficult. Instead I used a spring that we discovered works perfectly for removing the c-clip yet making sure your axle stays well seated in the carrier. We did this for 2 reasons. 1. The locker will not work without it. 2. It s easier to change the middle shaft if you have a breakage (don t have to take the carrier apart on the trails. Echo (weed-wacker head) spring # is an acceptable spring. There are many online suppliers for this part (pretty much any lawnmower or yard equipment supplier servicing Echo equipment), and it's cheap at $3 or so. The spring needs to be: 1-3/8" ID, " long, approx 30PPI spring rate. Secure the spring by using a clamping collar. After I got it reinstalled, fluid filled (80W90) and back on the tires I followed the manufactures instructions for the spin test and confirmed that it unlocks as it should.

5 Installation Supplement for Carrier Clearance (Dana 35 Models XD13527 & XD13530) Introduction While the installation is generally described in the manual that is included in the package, there may be some question on the sequence of parts installation in the Dana 35 Models XD and XD Note: Due to the overall bigger size of the Aussie Locker compared to others and due to casting differences of the Dana 35 differential cases, it may be necessary to grind/clearance your carrier during install. Also due to the size of the locker you will not be able to rotate the Cam gears of the locker inside of the case during the installation. Installation Procedures To install your Aussie Locker in the XD and XD differentials, perform the following steps in order: 1. With the case empty and still installed in vehicle, test fit the locker to find out if you will have any clearance issues. 2. Install the axle gears and thrust washers (make sure they rotate freely). 3. Install the ring gear side cam gear (without the pins installed) then rotate cam gear until it lines up with the cross shaft hole. Note: If the cam will not rotate when engaged with the axle gear pull the cam gear towards the center of the carrier then rotate. 4. Install remaining cam gear if possible and rotate until aligned with cross shaft holes. 5. If the locker will not fit (See Figure 1), proceed to Step 6. If the locker fits and rotates proceed to Step Since it was determined that the differential carrier needs more clearance we recommend the carrier be removed from the vehicle to prevent metal shavings from contaminating the housing. Note: Consult your service manual for removal, making sure you mark which side your shims and bearing races came from. You may elect not to remove the carrier from the vehicle. In this case, put a solvent soaked rag inside to catch any metal filings and do a final rinse with solvent.

While sitting on a bench, install the locker again and mark the case where it needs to be clearance (See Figure 2). Note: This step may be easier to perform if you also remove your ring gear. Mark the ring gear in relation to the carrier and install in the same position. In most cases only a small amount of material should need to be removed usually just smoothing down the casting is enough. Also the clearancing only needs to be done on the center to the right ½ (passenger side) of the case (See Figure 3), just enough to slide the cam gear in. 8. After clearancing the carrier, thoroughly clean and remove the metal shavings. Test fit the locker again. If all is well you can check your cross-shaft to spacer gap (See Figure 4). Note: Reference the installation manual Checking case Tolerances. 9. (5)Reinstall the case into vehicle ensuring that the shims and bearing races are located on the correct sides. Install the bearing caps, apply lock-tite to bolts and torque them to the manufacturer s specs. 10. Apply grease to the axle gears. Install the thrust washers on the axle gears and install axle gears into case. 11. Slide the driver s side axle-shaft through the axle gear, install the C clip, and snap back the axle. Note: Reference the installation manual for additional C clip installation tips. 12. Apply grease to the cam gears and spacers. 13. Install the spacers into the cam gears. In this application the pins will be installed after the cam gears are installed into the case. 14. Install the ring gear side cam gear and spacer (open end of spacer covers C clip and axle shaft). Hold the cam gear away from the ring gear towards the center of the carrier and rotate until cross shaft holes line up (The Flats of the Cam gear will be visible). Push cam gear back towards ring gear and align teeth with axle gear. 15. Install the remaining cam gear (See Figure 5). Rotate the cam gear to align it with the cross shaft holes. Note: Be sure the recess in the cam gear for the C clip installation is facing you. Push the cam gear as far as possible towards the ring gear (to allow for axle shaft and C clip to be installed). 16. Install passenger side axle shaft, looking thru the recess in the cam gear. Line up the end of the axle shaft (where the C clip installs) with the recess.

7 Installation Supplement for Carrier Clearance (Dana 35 Models XD13527 & XD13530) 17. Install the C clip using a small screwdriver or pick ensure C clip is completely seated on axle shaft. 18. Pull the axle shaft out to ensure that the C clip is seated. Note: Reference the installation manual for additional C clip installation tips. Regarding the insertion of this cam gear: This is a tight fit, there is only a small amount of clearance , if excessive grease is used or care is not taken with dirty parts or by sliding the cam gear in an unaligned fashion this clearance may reduce and the cam gear will appear not to be able to slide past the raised section of the axle gear, in this instance squeezing the already installed parts with a screwdriver or similar will ensure the grease is squeezed out from between them and down to a thin film yielding back the necessary space. If your diff has been re-shimmed with thicker thrust washers than normal (0.030 ), then it may be necessary to have these ground or replaced with thinner ones. 19. Slide the cam gear and spacer towards passenger side to engage the axle gear. Note: Reference the installation manual for additional C clip installation tips. 20. Install the pins. Apply grease to the pins, line up the cross shaft recess of both cam gears (this will align the pin holes). 21. Install pins into the notched cam gear space with the Step of the pin pointing towards the teeth of its respective cam gear. (This allows a location for the springs to seat on later.) Using a pick, slide the pins into the opposing cam gear. Repeat for all four pins. Note: Reference the installation manual for additional tips. 22. Install the springs. Wedge a screwdriver or equivalent tool between the cam gears to spread them apart and ensure that they are engaging the axle gears. Install a spring by sliding it into the notch and engaging the step on the pin. Then with a small screwdriver compress the spring and push it completely into the notch. Repeat for all four springs. Note: Reference the installation manual for additional tips. 23. Install the Cross-Shaft. Line up both cam gears with the holes in the carrier for the cross shaft. The new Cross shaft is drilled on both ends for either a bolt installation or roll pin installation. Set the bolt or roll pin into each of the holes to determine the best (tighter) fit. Once this is determined install the cross shaft into the carrier. Note: You may need to push apart the spacers if the shaft does not slide completely in.
