Gaz Posted July 21, 2009 Share Posted July 21, 2009 Am picking an escort diff up tonight or the next and I need to change the drive shaft flange over. I will rattle the nut off and replace the flange with the one that I need but then comes the problem. How do I know how tight to do the nut back up? There is a crush tube behind the nut. I kinda want to do it properly so anyone know the correct procedure? or is it just an experience/feel thing? Gaz Quote Link to comment Share on other sites More sharing options...
shizzl Posted July 21, 2009 Share Posted July 21, 2009 i would of thought youd just rattle it up tight.. good heads up there gaz cos im about to change the flange over on my hilux diff... is there a torque setting in a workshop manual for it? anyone?

Gaz Posted July 21, 2009 Author Share Posted July 21, 2009 Well if you do that then you would completely crush the crush tube which I don't think is good as stuff will bind. Id also say there is no specific torque because as the tube fatigues the torque would change. Gaz Quote Link to comment Share on other sites More sharing options...
Gaz Posted July 21, 2009 Author Share Posted July 21, 2009 Doesn't matter as much for rack/track/dirt cars as it will just whine I think? But this is for a street car and I want it as free as quiet as poss;. Gaz Quote Link to comment Share on other sites More sharing options...
filthy one Posted July 22, 2009 Share Posted July 22, 2009 there will be a torque setting etc as it should also adjust the end float on the crownwheel to pinion Quote Link to comment Share on other sites More sharing options...

My name is Russell Posted July 22, 2009 Share Posted July 22, 2009 Aiden knows how to do it ... he explained it to us over a year ago at UJ's old workshop. From memory there is a technique to it Why is the word lash stuck in my head? Quote Link to comment Share on other sites More sharing options...

Unclejake Posted July 22, 2009 Share Posted July 22, 2009 The 'lash' is the distance between the crown wheel teeth and the pinion teeth. It gets a little tricky on an old cw & pinion due to wear (the wipe pattern were one tooth has rubbed against another toothe for 40 years) but essentially use feeler gauges, read the manual, go slowly with the pinion nut and you can't go wrong. Alternatively just rattle it up tight and chuck a banana skin in the oil Quote Link to comment Share on other sites More sharing options...
orangeEsky Posted July 22, 2009 Share Posted July 22, 2009 i can have a look in my workshop notes, it has all the correct torques etc in it. if you need it Quote Link to comment Share on other sites More sharing options...
Borgweiser Posted July 22, 2009 Share Posted July 22, 2009 Fuck backlash, just crank it up for whiplash and weld inernals and do a skud ( not helpfull I know ) Whenever I used to change the flange on Escorts ( used to use Zephyr driveshafts and flanges for pinto conversions, now too rare/ easier options ) I used to just tighten them up and never had a problem, you have to really crank them to adjust/ crush tube and you only need it as tight as the nut yyou are undoing in the first place. Which from memory I used to undo with a 3/8 bar and replace with same bar... Could be wrong but I always thought Escort diff's had shims to adjust backlash and footprint like quality cars..

eke_zetec_RWD Posted July 22, 2009 Share Posted July 22, 2009 with diff head out find the back lash setting from a old book then use dail gauge to set it. kinda hard to explain. set dial gauge against a crown wheel tooth (in the center of tooth) and rock it one way and zero it then go other way to measure the lash. adjust as nesserary Quote Link to comment Share on other sites More sharing options...
Hemi Posted July 22, 2009 Share Posted July 22, 2009 i would of thought youd just rattle it up tight..good heads up there gaz cos im about to change the flange over on my hilux diff... is there a torque setting in a workshop manual for it? anyone? dont quote me but i dont think hilux diffs have the same crush tube . i rattle diff flanges up all the time but they dont have that siad crush tube in them . when i did the diff pinion seal in my escort i marked the before and tightened to the same mark by hand and a tiny bit more . .. but yea do it properly , good learning exercise Quote Link to comment Share on other sites More sharing options...
