Anderzander Posted May 19, 2015 Share Posted May 19, 2015 I have a transfer case on the bench*, I've swapped out the input gear for a cross drilled one, I'm going to do the O ring bodge from the tech archive ** ...... and it'd be nice to give it a good flush out if possible - is it feasible whilst it's in this state or is it only best to build it up and do a couple of oil changes? *well, an old duvet on the garage floor really. ** http://forums.lr4x4.com/index.php?showtopic=55338 Quote Link to comment Share on other sites More sharing options...
miketomcat Posted May 20, 2015 Share Posted May 20, 2015 You could flush it through with atf before refitting I believe atf has some rust eating properties (at least I hope so as my gearbox is brimmed with atf until I'm ready to run it) drain fill with ep90 before use then do a change after say 500 miles.

Bowie69 Posted May 20, 2015 Share Posted May 20, 2015 I'd say a bit of heat would help no end in getting the crud out of it, ATF has detergent in it as well, so Mike is onto something there.... Quote Link to comment Share on other sites More sharing options...
Anderzander Posted May 21, 2015 Author Share Posted May 21, 2015 Thank you both. It'll obviously be a bigger to man handle and 'swill' around - but it seemed worth putting something through it. If I may tag another question on : when swapping over the Lt230's would it be advisable to replace the seal in the end of the R380 ? I've a new seal to fit the transfer box - but don't know if it's worth doing the gearbox one whilst I'm in there too. Quote Link to comment Share on other sites More sharing options...
muddy Posted May 21, 2015 Share Posted May 21, 2015 We flush tractors out with diesel when the brakes delaminate. With EP90 being warm makes a big difference to the way it drains IMHO. Will. Quote Link to comment Share on other sites More sharing options...
DavidW Posted May 22, 2015 Share Posted May 22, 2015 Sorry to interrupt but is there a guide anywhere to swapping the Transfer box input gear? Thanks David Quote Link to comment Share on other sites More sharing options...

No it doesn't, this is an old wives tale that keeps being repeated. ;-) Quote Link to comment Share on other sites More sharing options...

The problem with doing the R380 rear seal is you need to make a tool to get it over the sleeve surface for the T/case seal. Can be done but fiddly.

Anderzander Posted May 23, 2015 Author Share Posted May 23, 2015 Thanks again Rick - on that basis I might leave it if it isn't showing signs of leaking. Quote Link to comment Share on other sites More sharing options...
