FPVF6355 Member 128 Member For: 13y 3m Posted 21/04/12 11:05 PM Share Posted 21/04/12 11:05 PM Hi,Anyone else have a Harrop truetrac fitted ?I had one put in about 10000 K's ago, and it was nice and firm to start with, and gradualy the rear end got clunkier on gear changed (manual)Anyway, finaly had a look, and found I can rotate the pinion about 10mm back and forth.Took it to the guys that installed it, and they put it on the hoist, and found that the free play is in the diff and not the CV'c or anything.Anyway, then he said that's normal !!!!! The truetrac gears are worn but they won't let go.I don't drive like an idiot, or do donuts etc, it's running 290RWKW and I do drive it pretty hard.But if they develop that much play, in 10000 k's how long will it last 30,000 ???? , If I don't do a real smooth gear change, and bring the clutch pedal up too quickly, the bang is really bad.The reason I upgraded from the original LSD was the LSD had exactly the same issue, so I'm a bit P'D off.

Tell them about the clunking, let them know you are not happy. Your workshop may just be trying to avoid replacing it under warranty, they will still have to foot the labour cost, Harrops only supply the part.

FPVF6355 Member 128 Member For: 13y 3m Posted 22/04/12 01:44 AM Author Share Posted 22/04/12 01:44 AM Youch !!That's the crown and pinion though, the tutrac is enclosed from those, except for the drive shafts.I did notice, that when I rock the tail shaft back and forth, the drive shafts input into the diff housing move up and down at a small angle.Considering I had a full rebuild , bearings, drive shafts, diff, crown and pinion, I'm pretty dumb founded that after 10,000Ks it has more play than a Nissan R200 I had, that's 20 years old behind a lexus V8 in a datsun.I'm no diff expert, but any gear arrangement is sh*te, if there is heaps of backlash, or free play, it just accelerates wear.

The car is too heavy = cut 400kg off it and stick all the F6 gear in this thing (roof would be nice seeing I'm in Melbourne) Aparently it's all just bolt in BA or BF parts :sungum: 1 Link to comment Share on other sites More sharing options...

It could be unrelated to the True Trac. 1 Link to comment Share on other sites More sharing options...
cobramad Member 824 Member For: 18y 9m Gender: Male Location: Perth Posted 22/04/12 12:02 PM Share Posted 22/04/12 12:02 PM Like Turbotrana says, there is something up, that may not be TrueTrac related... real mess of those gears and the metal has passed right thru the diff. Worrying problem indeed. All that backlash is probably due to the collapsible spacer continuing to collapse, dramatically increasing backlash. All that pounding has smashed the gears to bits. Consider a solid spacer in severe duty applications? Link to comment Share on other sites More sharing options...
