Cav/Calibra Transfer box bible disappeared...help!
« on: December 26, 2018, 10:27:43 AM »
Hi All,

Richard Kings Transfer box bible has disappeared - although still shown in google.

www.cav16.co.uk

Transfer box has recently gone bang so looking to his website for help on info. on the box & how to remove & where to get refurbished.

http://www.dorfbrunnen-garage.ch/englisch/vertrieb.htm still show cav16 as a distributor although phone number is discontinued.

I did have a local offline backup of his pages but disk discovered has failed so lost it all  :'(

Any info/mirror sites anyone can share would be appreciated or any other contacts?

TIA

JJ

Hi  :)

I have that manual......I could put it on a re writable CD and mail it to you......F.O.C. of course.  You will need to PM me your address first.

Richard King was the great guy who wrote the manual......He ran...www.cav16... Website some years back......He moved to Spain. You may find mirror sites but to save you hassle I can help.

Once you receive the Tx/box manual......just ask the club we have a wealth of knowledge.......I rebuilt my transfer box from a used Tx/box some years back so I and many members could also help you with advice if you get stuck.

Thanks Turbohead - pm sent.

I'll return postage + for your troubles.

Yes - my last "bulb" came from him.  Trouble is - never quite got round to fitting.  Young family took my time up & car took a bit of a back seat I'm afraid.

I will get to it as soon as my Xmas hangover parts company with my head. Lol ;D

When I removed my t/x box and stripped it down it was a mess inside.  Since I rebuilt it and changed the gear oil every year it has not failed me.

It will be interesting to see the condition of yours when you open it up.     When as you said your's went bang........did you get P.A.S fluid pour out of the rubber breather tube ??.......this is usually the first sign that the Ram Seal has melted.  >:(

Anyway until you receive the manual all the best for the New Year.  :)

Happy New year - hope the head isn't too bad.

No oil from the breather - and I've managed to get the "whoosh" working again so I'm thinking ram seal must be in tact.  I'm thinking the bang might have been related to a bearing failing as there was a terrific squeak coming from it first before the bang.

Rotating the rear wheels, I can *feel* roughness & snagging in the transmission.  Was hoping it might be a propshaft bearing but It appears to be coming from inside the transfer box so perhaps the clutch plates are catching or perhaps a bearing?  I guess there is a bearing on the output shaft from the Tx box?

Do working transfer boxes normally make any noise?  Turning road wheels in reverse gives an occasional squeaking like a dry bearing might.  Rear diff seems ok, as if the wheels are rotated in opposite directions to keep prop still and all is fine.

Planning on disconnecting the propshaft to check that the joints are okay.  Got car on axle stands but doesn't really give enough height so I'm thinking about making a set of 18" high ramps or perhaps build a pit to make life easier - especially if I need to remove the Tx box.

Sprayed bolts in penetrating fluid.  There seems to be a plate at the rear of the transfer box which attaches to chassis by a single? bolt which is stuck hard but prevents access to bolts on back end of coupling to transfer box.  Paranoid about shearing bolts  :-\

I've read that there should be a set of bellows between the propshaft and the coupling to the transfer box - is that correct?  If so - no sign of one.

Good news about the seal

If you picture I in your mind the transfer box is devided in two halves..........the section near the propshaft is full of Power Steering fluid to activate the ram plate.   The other half contains Gear Oil to lubricate the gears etc.

What happens when the seal on the ram plate fails is the PAS fluid is forced into the Geariing side of the box.  The mixture of PAS fluid and the Gear oil forces up the rubber breather pipe on top of box.......hence Oil all over the engine bay. The ram plate with seal is not available New............So you have to get a used one and hope that seal is ok.

I read what you said about the prop shaft and something about bellows ???.......on the end of the propshaft where it bolts on to the rear of the transfer box there is a kinetic joint which is fitted with a metal cap with a rubber boot attatched and is filled with grease to lubricate the kinetic joint.

If the rubber boot is missing then all the lubricating grease will have gone.......this would leave the kinetic joint to dry and seize up.  Water ingress would rust the ballbearings etc and cause the joint to fail. This could have been the source of the noise you neared.

If this is what happened.......you can buy the joint cover which has the rubber boot bonded onto it. You would also need to buy a used propshaft section with an undamaged Kinetic joint.

I am posting the info you wanted tomorrow .
