New Gear Box install, any tips?

My Ashcroft gear box arrived and it is very purdy indeed.

I will be installing it next week.

Any tips at all for installation?
Oil?

anything at all.

Thanks.

If its the main box you are fitting obviously check the clutch / pressure plate and bearing, , check the release arm pivot point for wear / cracks and make sure its greased (might be worth replacing the pushrod clip as it may be getting brittle and give you grief later, crank oil seal for weeping and the spigot bush in the end of the crank. Basically anything in that area is going to cost you a lot of time if it goes wrong so make sure it is good.

I was told that I don't need any parts to do the install.

No gaskets,seals......

Is this correct?

Thanks.

just oil.

Hi Natas, a nice sight a new Ashcroft transmission is indeed!

R380 box? MTF94 Manual Transmission Oil (LR sell it cheap enough - 3 one litre bottles will do it) and stick a new clutch kit in (whole thing - bearing, bushing, fork - HD version or weld a plate on the back, plate and cover) unless you actually know it to be fine - I would even be tempted to fit a new slave while I was at it or rebuild the original - I realise that parts and things are maybe not as easy for you to obtain there but I would try - you won't regret it.

New clutch kit and HD fork was just installed, slave is fairly fresh.

Ashcroft says MTF94 OR ATF dextron 3.
They say that they have had better results with the ATF.

"The oil recommended by Land Rover is MTF94. However we have recently found this oil to give better results ATF"

Take loads of pictures for us so we can see how you get on.

What oil do you use for the transfer case?

Have you got a cooler on your 380? presume so, as it should be a ROW spec from your location - I might suggest ATF in that case - but I have just changed the oil in SWMBO's 380 for ATF as a flush, and it was 'orrible, so its now back on MTF94 (Which was the plan).

worth a nosy round this forum, maybe join and ask the question:-

Transfer box should be EP90's it might be worth the expense of a fully synthetic...

So,

Got it all back together and cant get the diff loc to engage.

I can go hi to low but cannot get the light to come on.
I figured maybe the light was broke but when I put the selector where it should go for diff loc I can still turn on pavement without it locking up so I figure its not engaging?

Help.

Some piccys



Old box out



New box (Ashcroft) all the way from UK!

So, first drive.

1st and reverse gear are difficult to engage at times.

I am hoping that this is because its a new box?

could be because baulk rings need to bed in ,or clutch is dragging more than normal;

Ashcroft said to run it for 1000 miles and then there should be a difference.

I tale Pumkin on vacation next week Thursday, that will be an easy 800 miles, hopefully I will get the diff loc sorted by then.
