So I looked at this disco today

Ok well I emailed the fella and asked him about the gears. I haven't heard back from him yet, but I might give him a call tomorow. Interesting you bring up towing slug burner as the owner told me that the Rover spent the first so many years of it's life towing a caravan around the area. This input gear PTO thingy would be very important for a Disco that has done some towing. Early in the thread someone stated crossed drilled What is that about? Would I be just looking for worn gears or was there a replacement set or something that looks different from the one utemad posted.

See the smooth area between the bearing on the left and the teeth on the right. The cross drilled gear has two holes drilled right through in a cross pattern which leaves you with four holes to let the oil in/out of the splined area.

This link to the Ashcroft site has some great info and pictures.

Thanks Justin

Yes that site has heaps. I was just reading a bit.

Identifying your Unit

The LT 230 was fitted to all 5 speed Defenders, all Discos and the RR Classic up to 1988. The serial number will be stamped in one of 2 possible places, either on the bottom left of the main casing or on the earlier vehicles right at the bottom of the left hand side face of the main casing obscured by the exhaust pipe in which case you will need a knife (to scrape the muck off) and a mirror. You are looking for Eg. "28D123456E, we are interested in the first two and the last, i.e. we call this a "28E"

Did they mean 1998?

If so is this a way without opening the Transfer case to see if the cross drilled gear is inside or is that simply stating that it can be retro fitted to that model of transfer case?

also

We can supply both the earlier (26th tooth) and later cross-drilled (26th and 28th tooth) input gears.
To identify which type you need you will need to look at the your transfer case serial number. The last letter of this will denote whether your vehicle is able to accept the later cross-drilled type. A transfer box with the suffix A or B will only accept the earlier 26th tooth, non cross-drilled type (FRC5428). A transfer box with the suffix C onwards will accept the later cross-drilled type. To see how to identify your transfer box number please look in transfer box introduction.
Suffix A or B use a FRC5428,
If you have a 200 Tdi Disco or Defender or a 300 Tdi defender these all take a FTC5089.


Since we are talking a 300 tdi disco as noted above does that imply that they all had the cross drilled input gears to start with?


Chris

Just out of curiousity as I'm learning heaps on this here was this problem specific to MY1995 or did it span several years? Is there a Disco MY that had this problem corrected at the factory or some earlier year where they used better parts.

I think MY97 was the first to get the cross drilled part. Not 100% sure.
Before that all LT230s would have been susceptible to wear without the oil feed plate.

This thread has tended to focus on just this one problem however I am sure there are other things you need to look at with the 300Tdi. Like the fact it is missing 4 cylinders :wasntme::burnrubber:

Very funny Justin:D:D:D

I remember a friend of mine asked me to do a pre purchase inspection on a 2 year old Zetec 2 litre Focus. Nice little thing. He rang me and asked what I thought of it. I said it was a nice car but had a few missing components. 'What's missing, let me know and I'll negotiate a lower price with the used car dealer:mad:!!' said he, to which I replied 'A turbocharger and rear differential':p:p
