4x4 problem
« on: January 07, 2018, 00:09:39 AM »
hi guys, i have a problem with my calibra turbo 4x4.
last day, Hydraulics flowed behind the Accumulator Bulb, like a valve.
i saw there is a cover and It's standing outside the nest. i put it in it, close the cover. then i fill the Hydraulics.

(Hydraulics flowed from number 2)

But it did happen again?

why is this happening?

thanks for replay..

Hi and welcome!  :) No experience of 4x4 Callie bit I am sure others have. Why not introduce yourself and your Callie in "Newbies and Hello"?   8)

Hi ...Welcome to Cc.

There are turbo owners on here that may be able to help  and they will do their very best to help.

Can I direct you also to a website Called........Cav 16 .....where you will find a goldmine of info and manuals......founded and run by a great guy..........Richard King.

He will know or even contact the company who rebuilds transfer boxes. to find out.

I own  1992 Calibra turbo 4x4 ......and have rebuilt mine some years ago from a spare box.....however I am unable to diagnose the problem you
describe but sounds to me that the 4x4 sphere could be over pressurising.....which could mean a new sphere is needed.

The latest replacement sphere is painted all black.........so if your's has a white ring around the top it may be faulty.

Anyway try CAV 16 website.

I feel your frustration.  :-\

I noticed after reading your post again that you have removed fuse 19 and that means of course .....your driving it in 2 wheele drive.

This is the point I think that you should now decide if you wish to get the 4x4 system working......or convert the box to 2 wheel drive permenantly.

Not sure if you know that a special plate is needed to do this and is available on eBay.

Have you had hydrolic oil coming out of the transfer box breather pipe........if so this indicates a ruptured seal in the ram plate. If this is the case your only option is to buy a working second hand box as a new seal is unattainable.

Good luck in whatever you decide to do ;)

Keep us posted.

I was hoping other turbo owners could give some advice here.

I have my 4x4 system switchable too but I have a problem trying to visualise the source and cause of the leak.

Is it possible to take a photo and post it up .......there is advice on how to do this.......and it would make a diagnosis more easy.

Are the high pressure hoses bolted on tight........is there a leak on the rubber part of the hose and it is running along towards the leak ??

Sorry I cannot offer you the advice you need but without seeing the problem it is hard to come up with good answers.

You might be better to buy another hydronic sphere assembly and plumb it in.......unless someone knows how to fix the one on your car.

Good luck
