Footcutter11 23 Report post Posted October 6, 2015 Ok you rear guys... How's my pattern? Quote Share this post Link to post Share on other sites
Rsmach1 71 Report post Posted October 6, 2015 Not an expert, you need to spin it again or use a little less marking compound. From my perspective looks like it needs to be a little closer to the toe (inside of gear) check both drive and coast. Coast should be centered. Edit to check coast spin the ring gear, and the pinion for drive. Quote Share this post Link to post Share on other sites
Rsmach1 71 Report post Posted October 6, 2015 Also, when you spin the pinion, place your hand on the ring gear for a little drag, that will help define the pattern. Do the opposite when checking coast. Quote Share this post Link to post Share on other sites

1969_Mach1 333 Report post Posted October 7, 2015 +1 with Rsmach. I wedge a block of wood between the ring gear and the case when I rotate the pinion gear to check the contact pattern. When the pattern is correct both the drive and coast side will be very close to centered on the tooth. When the contact pattern is off the patterns will be opposite between the drive and coast side. I.E. towards heel on the drive side and towards the toe on the coast side, or visa versa. Quote Share this post Link to post Share on other sites

MikeStang 247 Report post Posted October 7, 2015 How did u set the carrier bearing preload / case spread? Guy who did my rear end said run the spanner nuts down on the side without ring gear till it stops then on the ring gear side do same thing but once it stops put the spanner wrench on it and go 4 hokes and it will be dead nuts on 99% of the time. Think I got that right Quote Share this post Link to post Share on other sites

stangnet33 88 Report post Posted October 8, 2015 Looking at the pic's on my phone it looks like the pinion might be to deep (half moon pattern). What do you have your back lash set at ? Also it's advisable to check the ring gear in at least 3 different places ( helps to make sure every thing is true) JMHO Quote Share this post Link to post Share on other sites

Think I got that right You set the carrier bearing preload by measuring the rotating torque at the pinion nut with an in-lbs torque meter (not torque wrench). You first measure and set the rotating torque of the pinion bearing preload without the pinion seal installed. Then measure the rotating torque of the entire assembly (still without the pinion seal installed). I don't recall the exact specs for new and used bearings. I guess if you have done a lot of them the method the guy who did yours would work. Sounds like a short cut and a little sketchy for my liking. I've heard of measuring case spread to set the carrier bearing preload but have never seen anybody do that. Quote Share this post Link to post Share on other sites
