Thread: R380 cross drilled gear thingamybob

I think I would only try to pull it off if I felt there was a problem after the test drive.
Although you could just say you want to remove an inspection plate

I'm so close to buying a Disco I can smell the oil on the driveway

Fairy muff. Thought it was worth mentioning.

As I said, "Good luck in your choice".



Now, off to drain & replace the R380 ATF with Redline MT-90.

Bloody job.

No worries. I was actually thinking it was easier than you said. It's good to know these things before you whip the spanners out. Especially on someone elses car

I didnt know about this problem before. Did the LT77/LT85s have this problem too? Or do you drill something else with those?

I'm glad my vehicles had LT95s, can't go wrong with them.

Steve Parker mentions the applicable boxes on his website.

The crossdrilled gear & Oil Feeder Plate achieve the same thing.

ie. Get ample oil on to the shaft spline.

The input gear can be removed through this cover. Rotate the intermediate gear to a position where the teeth of both intermediate gears are inline with the input gear.

Now that I actually have a D1 I am trying to locate a backlash problem that has developed since Saturday night.
I have removed the round cover from above and to the left of the brake drum. I've also removed the internal cover. Now how do I get the gear out?
I can see a gear but cannot move the gear at all.
Do I have to rotate the gear I can see to get it to come out or rotate something else?

Thanks

Did you try with the gearbox and t/case in neutral?

With some ratios, you have to rotate the t/case gears to get a space between the teeth of the intermediate gear to line up with the tooth of the input gear - so the input gear can be removed. But I am pretty sure this is not the case with a disco.

This 'lack of lubrication' wear causing drivetrain backlash happens gradually from the day it is first driven.
If yours started suddenly, the tranfer case input gear issue is unlikely to be the problem.
