Thread: Transfer box/case removal (how to)

That's the first

That's the first

I assume the mechanic is talking about the intermediate shaft seal and machining he case to install a steel bushing. You really would not know of this is needed until the case is out. It could just need the 10 cent o ring.

You need to clean it well and then see where it is coming from.

If i was you(cos i was in the same situ) i'd use a master rebuild kit from ashcroft as the box is off anyway, it's not very expensive and has everything you need in it as long as the box is in good working order Ashcroft Transmissions

I was willing to do it on my own making a "how to" guide for all the forum people replacing with the genuine seal that in the worst case will last as the one I have (180000 km).
First of all I need to understand where exactly Is the leak from and I need your help guys
I took some pictures (not really good pics) that I hope can help.
Thanks in advance

Jack
go to the bottom of the page here and "search" for the T/F case removal
you should come up with some excellent Tutorials on how to go about it
you will need some specialist tools for a complete O/haul
even for R&R you need some to help make it easier particularly the guide bolts for R&R to prevent damage to shafts and seals.
One Really Catchy little Gremlin is the bolt you show in the Foto as it is a Measured length that if it is too long it will touch the Idler gear in the T/F case." I found this out the hard way".1st out last in is my best suggestion and paint the bolt head a bright colour when removed to prevent mixing it up with the others.
good luck with your task.
cheers

but don't try rushing the job give yourself a good 2 days if you haven't done it beforehand.

I recently had mine done by a specialist, and it leaked worse than yours at 165Kk.

It cost $750 , without fixing the case and it is now not leaking at all, as they used an epoxy to seal the end of the shaft. IMHO it is worth getting done if you are old like me as AFAIK the case weighs 70Kg.
