Guide to 4x4 Transfer Box Oil Types
« on: May 09, 2006, 21:39:52 PM »
Transfer Box Oil Type

According to Courtnay Turbo, this is a problem with the grade of oil as specified by Vauxhall.

THE SOLUTION:
Use 80/90 gear oil in the transfer box instead, this should greatly prolong the life. Also, it is important to keep all 4 tyres identical and with the same amount of tread. Always change all tyres as a complete set - never change just one tyre or just a pair as this will cause excessive wear in the transfer box.

?? Thought that special oil for the T box was a higher temp grade oil as the viscous in the box works on heat? think operating temps for viscous were around 130 to 150 degrees have to look into it.

the 1st fluid vx spec was just pas fluid, it tended to froth up removing the fluid from were it should be and made the box oxverheat as the throth doesnt work like an oil as its spread out,
the new stuff from vx has never given me any problems, smells like atf(pas) fluid but is thicker so doesnt froth up stays were its meant to be, works fine

If you have to own a Calibra; make sure it's the 4x4 turbo. You dont want to fanny around with a FWD car.

Regarding the transfer box oil the problems grew from Vauxhall advertising. i.e they said that the box was maintinence free.
which meant that some owners never replaced the oil. Cosuquently the viscosity of the oil degenerated so became inadequate to
efectly cool the oil  and so protect the the ram seal from melt down. When this occurs the power steering fluid which opperate the 4x4 system forces its way under high pressure and fills the gearing side of the box. This is why you have the pas oil forcing up the box breather pipe into the engine bay and onto the road. I have suffered this problem first hand and fixed the box myself with advice from Richard King founder of the Transfer box bible @ www.cav16. If any members needs to know all about the transfer box I urge you to go to this great site.

The secrets to prolonging it's life you should observe the advice about tyre tread etc because failure to do so puts more pressure on the box and will eventuly lead to destruction. The main strong advice is as in my case is to change the gear oil once a year and the box will go on and on happily gripping the road like a train on tracks.

welcome to CC.com to start :)

Cav 16 is a very well known site on here, especialy to the 4x4 owners. tyre depth a and camber are a well known issue as is replacement of the accumulator bulb (which I replaced last year from cav 16)  I personly replace my TX oil at each 3000mi engine oil change
but as you say look after it and it will last you ;)

I have not failed. I've just found 10,000 ways that won't work.

Hi martin and thanks for the welcome as a newbie. I agree with you that changing the oil every 3000mi is a very good practise.
I'm sorry I meant to say change the oil at least once a year. I rebuilt mine using the best parts from a spare box 5yrs ago and is still going strong due to oil changes.  :)
