Guest gtmen Posted November 19, 2004 Share Posted November 19, 2004 I am replacing the front rotors on a 93 XE and it looks like the bearings are pressed into the rotor assembly. Is this true? if so, how do I get the bearings into the new rotors without any twisting etc? Link to comment Share on other sites More sharing options...
robinasu Posted November 19, 2004 Share Posted November 19, 2004 you need a press or a wheel bearing tool. The tool is essentially a disk machined on the edges to interface with the outer bearing. There is a shaft mounted at the center and perpendicular to the disc that you hit with a rubber mallet to seat the bearing.. then, when yo re-install the hubs you are supposed to torque the bearing down very tight, then release, then set the proper bearing pre-load. Check the manuals first to get all the details I missed and to error check me! Link to comment Share on other sites More sharing options...

MatterHorn Posted November 20, 2004 Share Posted November 20, 2004 that's what I thought ... as long as the races aren't worn, you shouldn't have to do anything with them except repack and replace the bearings ... set the pre-load and off you go ...

Greenbushy Posted November 20, 2004 Share Posted November 20, 2004 Hammer and a punch works every time in the bush and if the truth be known probably most workshops, certainly most workshops ive worked in, ,, just be careful when doing it this way Greenbushy Link to comment Share on other sites More sharing options...
robinasu Posted November 20, 2004 Share Posted November 20, 2004 How do you guys tighten the front bearing lock nut? Is there a special tool, did you make one, or did you use the old screw driver trick? Link to comment Share on other sites More sharing options...
94extreme Posted November 20, 2004 Share Posted November 20, 2004 ... did you use the old screw driver trick? yup Link to comment Share on other sites More sharing options...
Greenbushy Posted November 20, 2004 Share Posted November 20, 2004 Yep you guessed it the good old screw driver, i know it sounds rough but once ya been doing this sorta thing for years you get the feel for just how tight the bearings are, ya see most smaller auto repairers cannot afford every special tool for every vechicle so ya gotta improvise, obviously some shops and mechanics are better at it than others.

Guest gtmen Posted November 21, 2004 Share Posted November 21, 2004 What are the pitfalls of the hammer/punch method? since i'm replacing the rotor I have to knock the races out of the old one don't I? does the hammer and punch get that done as well? are there any step by steps online? I have the chiltons manual but it presumes that you have all the tools (which I obviously don't) Link to comment Share on other sites More sharing options...
Greenbushy Posted November 21, 2004 Share Posted November 21, 2004 No you wont have to remove the wheel beariing cups ( The bit that is pressed in ) these are pressed into the hubs and the rotors are bolted to the hub, undo the nuts holding the rotor, knock the bolts out, careful here dont damage the end of the bolt use a soft brass punch, then use a hammer to seperate the rotor from the hub, it may need some effort because they ussually get rusted on. Clean up the hub where the rotor sits with some emery cloth and put a bit of never seize or grease if ya dont have any of that on the hub where the rotor sits and sit the rotor on the hub put the bolts in and tighten evenly to make sure the rotor is seated evenly. Repack you're wheel bearings ( best to wash them out with clean kerosine and air dry) with htb wheel bearing grease, refit hub and tighten wheel bearing nut with ya special screw driver and hammer use a pointed screw driver to save damaging the holes in the nut where the special tool should go. Best method to get right tension on wheel bearing is to: tighten nut up really hard basically so it cant move any more with the screw driver, rotate the hub a few turns then back the nut of so its loose, retighten the nut again till it wont move again spin the hub and loosen the nut so its just on the point of being loose by about a quarter of a turn then tighten back up about a quater of a turn, you should be able to move the nut without to much effort to get the locking screw holes to line up,, now best if ya a beginner to fit the wheel at this stage without the locking hub and one hand on top and one hand on bottom of wheel try to move back and forward should be just a little bit of movement , not much just a bit .. ya dont want the wheel bearing to be too tight or loose for that matter so try for that just a bit of movement having left the locking hub off you can still get at the nut and readjust if nessecery.. Hope this helps Greenbushy phew i need a beer after that.... Link to comment Share on other sites More sharing options...
94extreme Posted November 21, 2004 Share Posted November 21, 2004 make sure too spin the wheel forward and backwards to seat the bearing... V. good greenbushy... Link to comment Share on other sites More sharing options...
Guest gtmen Posted November 24, 2004 Share Posted November 24, 2004 Greenbushy you have saved my life! I thank you, my pathy thanks you and everyone on the road who was at risk of my brakes thanks you! You ought to be writing the manuals. Chilton could learn a thing or two about explanations. Thanks again! Link to comment Share on other sites More sharing options...
