OK...so this is the story...my box has a hole in it...luckily died after having only done a few miles back in England, would have beenannoying if it did it in Morocco.

The casing was expensive to buy genuine, so thought it would be best to plump for a new (old) box complete - the idea being I could then strip this "new" box and replace parts where required. However the "new" box (which is an early Series 3 rather than a 2a) needs a fair few parts.

If I buy replacement parts (I tend to get from LRSeries) it will cost £116.71 (lay shaft 576686 reverse idler 576707 inner and outer member 608283 reverse shaft 591527) - this is without bearings...and I already happen to have a genuine LR gasket and seal kit. However, if I buy genuine LR parts, the same parts will cost £319.60!!!

So I am unsure what to do...I nearly always get genuine parts nowadays as cheapo bits have annoyed me in the past...but...thats quite a lot of money esp as that is not the full list of things I need! Are there bits that I should deffo get genuine? Known issues with replacement parts? What about the bearings as well, as I will be renewing them as well?

Cheers guys :)

Guy who rebuilt my box said he only uses genuine parts. If you do a good job on your rebuild and use quality parts, should be good for a fair few more miles. If you use cheaper parts and then in the not so distant future have to crack it open again..you won't be happy.

It's one of those 'can't afford to do it cheaply' jobs. Trying cheaper parts on some things isnt so much a problem, worst case is buy the part again and refit. But with a gearbox, tad more work involved.

At least if you bite the bullet and pay the extra, you won't be left wondering if you should have spent more.
 
i would be surprised if you could get genuine parts now,brgs is different and only use oem

Can deffo get genuine parts, no problem with that!

Indeed, this is my worry! Sometmes is the case though that sometimes the replacement parts can be as good as the genuine...jsut wondered if anyone had any experience with it.
 
Yea, sometimes you can score lucky with stuff - not disputing that at all. And it may be you'd hit lucky with the box parts, but if not...seems somewhat of a gamble..you won't know you've won the gamble until you sell her!
 
Right, I have plumped for the genuine parts, thought given the places it has taken me, the old thing deserves it!

I am combining the good bits of the current box and the old box. Having stripped both boxes down now, there are a few teeth missing, springs missing and all sorts...the main expensive part I need to buy is the layshaft as that is knackered on both. Next weekend will be putting the box together :D

Good lad - genuine all the way when it comes down to engine and gearbox IMHO ;)

Pics pics and more pics pwetty please ;)
 
I would have gone for a non-gen layshaft.
I got a Britpart labelled mainshaft and some genuine gears to rebuild my 'box. Same stampings on both, so I don't recon britpart made the shaft.....

Check Dunsfold as well, they are sometimes cheaper than LRseries and only sell genuine.
 
Bits are ordered now anyways :) Jsut have to put it all together, and then the car back together...and hope it all works :D

Another quick onee for you lot...GL4 and GL5 EP90...for some reason I have it in my head that the "modern" GL5 is not good for Land Rover gearboxes...am I imagining this...if I am not, then what is the issue?
 
eats the synchro rings? seem to remember a mate's spitfire manual saying something similar about the diff oil, something about the phosphor bronze thrust washers being eaten by the additives in the GL5?

maybe.

apparently it 'melts' the copper washers in the diff. don't see how that would affect a landy gearbox, unless there's copper washers in it.

I thought they changed the additives in modern GL5 to ones that don't eat phoshur bronze....not entirely sure about that, but I remember reading a Millers Q&A in mag about it.
 
Just doing a series 3 box. Ebay has some genuine 608283 on at the moment for £23. I have bought one. LR Series and blanchards sell good stuff. The bearmach 2a pinion from LR Series was a genuine item.
