Thread: Filler plug for transfer case??

I think it is 1 - but I am not an expert on this box, so wait until someone who knows what they are talking about replies.

I'm with John on this one....I'm not an expert on this box either

But to me it has to be 1.

The damage to the plug suggests it has been worked on numerous times and the fact that there is yellow paint is an indicator for many machinery applications to add, check or fill oil, grease or whatever. Another indictor is that my D2 has the same type of filler plug. Just use a half inch breaker bar and it will come straight out.

Plug 2 does not have any markings at all as far as I can tell and it is very rare for a standard fill plug to be split pinned. As far as I know race cars usually have their drain plugs wired to stop them from dropping out, but as for fill plugs I'm not sure.


EDIT: Some smart bunny will now come along and say the transfer boxes are the same in a 87 RR and a D2

Yep

It is the large plug near the sticker with the high range ratio.

The other nut is for setting the pre-load of the taper roller bearings in the intermediate gears.

Thank you for the help.

Yeah, Its obvious that someone has had a fun time trying to get it off previously.

Im going straight to get some oil, because low ratio was making some very strange noises yesterday on Goolwa Beach!

I hope everyone is enjoying their christmas break!

Remove it with a 1/2" square socket bar.

Make sure you can remove it before you drain the oil.

I searched 3 auto stores for a 1/2" socket bar! None to be found.
It was stuck on there good and the previous owner had started to chew it up (see photo). I ended up stopping at a mechanics and he go it off after a few minutes and alot of effort!

Thanks guys.

You don't have a standard 1/2" drive socket set?
