LT230 input gears and their problems 

Let’s not forget they did a dry spline output shaft on the puma mt82. Despite having done this previously.

Just stripped my 200 TDI and was happy to see a cross drilled gear. I always assumed that what really killed the gears was not lack of oil, but that it had the effect of a centrifuge. As in a rotational oil filter, all the muck and impurities collected to the extent that it prevented what little oil was going in, from getting out. From that point the interfaces were effectively unable to receive oil, and ran dry. As in the td5 rotational filter, it was very effective dirt trap. I never found rust as such, and certainly unlike the dry shaft fit found in the L322. Now that shaft was subject to a recall or replace, and I suspect because of class action in north Americas, you could still get those parts for free today. And the L322 arrived in 2002. Most classic range rovers and discos had no PTO teeth as the floorpan prevented fitting useful accessories. I have an early pre production chain driven box in 1.6 ratio. For 110 it was fitted to lt77. It's half Borg Warner/half land rover. A real oddball. No lubrication problems as totally different design. And yes. I happened upon one of those customer custom welded units. A disastrous repair option. But. This is Ireland. Not much would surprise the time served spannerman here!

My 300tdi Disco had this problem when I bought it about 15 yrs ago. Clunked badly. After some investigation I found that not only were there no drilled holes but the splines were short too. This meant that I could fit a drilled gear with longer splines(Latest iteration) & these splines were now in contact with the un-worn part of the shaft's splines. End of clunking.

Britannica Restorations Ltd, You're the best! I subscribed because I love your content!

I was told by a lr dealer principal that if the customer complained enough about the gb issue in warranty they then would extend the cover for the time the customer owned it

Thanks very much Mike. That helps me understand what I'd be looking for both for the one on the bench and the one in the vehicle. Very helpful.

Its not much but I send some with my Heart You are a fine man and in the Future we need to know there

Very informative Mike.

Top !! Thanks a lot for your Help

This type of info is love/hate.

Just fitted a Ashcroft T/box ,very happy 👍🏻

Hope I’m not the only one who beat you to the milk tray gag Mike?… Funny how adverts stick with you

Maybe LR thought that when installing the PTO ,lubrication was solved?

Hi, When does this knocking sound occur? I have a similar knocking problem when I go around sharp turns. Really interesting video:)

incredible knowlegde .... but now you got me worried. do the series gearboxes

actually, i need to know more about the PTO drive, more so with what actually attaches to the output shaft... im attempting to make my D1 camper(with diff) a driven trailer :)

Here's a fine question for you: My 90 has a lt77/lt230. They guy I bought it from told me that "he welded the lt77 output shaft to the lt230 input shaft" due to spline wear. Everything seems to work ok, 2 years after this, no issues or weird noises, I changed fluid yearly on the tcase and once in the gbox.

Does the Borg Warner suffer the same?

H i I've got a problem on my landrover defender which is fitted with a 300tdi and an automatic gearbox zf 4hp-22 from a Discovery 1. The problem is that the reverse light is not working. Can you please tell me where I can find the reverse light switch on the gearbox ? Thanks for your help you give to all Landrover lovers. Raymond

reading other threads it seems LR started fitting the cross drilled gears around 1994, does that sound about right ? Mine is a 1997 300tdi so hopefully should be good if true
