But there are full spools out there that fit up to hilux a old boss had a hilux diff in a 8.90 drag car. Never missed a beat.

RUNAMUCK Posted March 24, 2019 Share Posted March 24, 2019 Has it been mentioned yet that the bigger the gearset, the greater the driveline losses? I've heard tales of cars doing slower E.T.'s after going 9" from BW diffs. The two pinion bw75's are piss weak junk though. I've seen many many many of them thow in the towel. Back in the day dad's XD work ute used to eat one about every 9 months. His Val has put quite a few two pinion ones to the sword too. 1 Quote Link to comment Share on other sites More sharing options...

cletus Posted March 24, 2019 Share Posted March 24, 2019 Would always be the spider gears that let go wouldn't it? The ones I've broken have all been subjected to teenager activity, ie big one wheel peels till the spider gear melts a bit and it and the pin goes blue and says yeah nah I'm out of here next time you drop the clutch 2 Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted March 24, 2019 Share Posted March 24, 2019 One got very hot (trying to unlaunch a boat stuck in sand) and wore through the hardening on the gearset. That one was a 75, 25 spline with a four pinion open centre. Quote Link to comment Share on other sites More sharing options...

I have no real world first hand experience with BW75's. This all makes for interesting reading. In all honesty, most of the damage I have seen in the stuff I am asked to fix or modify has come from shock loading (I guessed you'd call it) brought about when power meets hook. But then that said, I reckon when a certain et/mph is reached, then by nature of the beast you need to get you there - everything is stressed to destruction at some point. I've seen heads out of rides that go out the backdoor at around 200 and their stuff munts. Quote Link to comment Share on other sites More sharing options...
johnny.race Posted July 10, 2019 Author Share Posted July 10, 2019 His paint doesn't shine anymore and he hasn't got an un-dinged panel to his name. He's runs leaf springs in the front and is almost topped out at the legal speed limit. 26 years young and still the fucking business! Coon diffs. Thought of you @igor :)) Hey @yetchh I had to go back and check those pics you posted earlier. Two of these diffs feature vented rotors. I'd seen the later type before but not the cast iron type. The car was an XC by the looks of it. They are like your ones aye? It was stripped and had been fucked over by the loader, but XC as far as I could tell. The later one was an XD and the drum one was out of a ute that was either an XB or an XC as far as I could too. The old stuff is still out there, just gotta look wayyy harder now. All of them measured in at 1550mm outside to outside give or take a few mm either way. I have got a couple of 9"'s to do so have been tuned into BW/Ford sorta stuff of late. Stay warm. 1 Quote Link to comment Share on other sites More sharing options...
yetchh Posted July 10, 2019 Share Posted July 10, 2019 Yeah that's them, late xb had them also.. strange about the xd, I was of the opinion that xc and xd/e had the same calipers.. Although there are two types I think. After our earlier discussions they look more like xf.. Quote Link to comment Share on other sites More sharing options...
johnny.race Posted July 10, 2019 Author Share Posted July 10, 2019 Hmmm, maybe I got the XD part wrong. The only distinguishable part to me was a rear tail light and it looked like from what i remember as being XD. I'm not a Fordy guy and only know then by body shape pretty much well. Did the later ones (the next ones) have XD-ish type tail lights also? The car had been munted by the loader and digger before I got told about them. Of note, the later one has a link setup and not leaf. Would that say i was wrong thinking it was an XD I was looking at? When did the coons go to that 4 link?

cletus Posted July 10, 2019 Share Posted July 10, 2019 XD sedans were leaf springs, XE XF sedan was 4 link, all utes and wagons were leafs though Quote Link to comment Share on other sites More sharing options...
johnny.race Posted July 10, 2019 Author Share Posted July 10, 2019 Ahh, ok then, @yetchh was right, I stand corrected. It was a later coon I saw the bum of. Sweet. Water blast and tuck these things away for a rainy day and tear down. They are all LSD's too. I'm wondering if that ute one might be a 25 spliner.

cletus Posted July 11, 2019 Share Posted July 11, 2019 Good chance it is 25 spline. I used to look for xd-xf ute or panel van diffs to get 25 spline lsd centers to put into valiants, utes often had 3.23 ratios, sedans if they were lsd were usually 2.77 which had a different offset ring gear mount surface which didn't work for any other ratio 2 Quote Link to comment Share on other sites More sharing options...
cletus Posted July 11, 2019 Share Posted July 11, 2019 And grab a xf diff cover and chop the watts linkage pin off, that is a poor man's pick a part combo to try and make a valiant diff more resistant to making bang tinkle crunch noises haha Quote Link to comment Share on other sites More sharing options...
Valiant Posted July 11, 2019 Share Posted July 11, 2019 I have a 25 spline 3.23 ute diff in my valiant. Works well. 1 Quote Link to comment Share on other sites More sharing options...
