Canadian Centurion tanks question

Tony, 3 years ago when I was last working on the tank, I found the rear fuel tank rusty inside with the worst on the floor (no sand). I cleaned it and vacuumed it as best I good but access isn't good, and sprayed the interior with preservative oil. We'll have to think about what further cleaning we can do, or whether we'll settle for some heavy duty filtering.

Or make a new stainless tank using the original fittings and designed in such a way that you can use the last bit of fuel rather than permanently have 20litres going stale.

i cleaned the long range tank on one of my cents last week. fairly simple to remove the drain plugs and give it the good news with a high pressure steam cleaner.

Mike did all the Australian Centurions which served in Vietnam have the up-armored glacis and .50 ranging gun?

[Mike Cecil]

We are straying somewhat from Malcolm's initial question, but I think that has been answered satisfactorily by this stage anyway.

Australian Centurions sent to SVN - gun tanks, command tanks and dozer tanks - were fitted with:
- RG (with associated changes to the sighting system to correspond to the new ranging technique)
- applique armour on the glacis plate
- IR
- LR armoured fuel tank on the rear,
- internal changes to allow stowage of the IR sights & periscopes, the IR batteries, and the .50 cal ammunition liners.

... with one exception: one of the first two dozer tanks sent to SVN in 1968 was not fitted with RG and IR, and was not fitted with the basket, commonly called an IR basket, on the rear of the turret. A 'home grown' basket of smaller size was fitted in SVN to provide additional stowage.

Mike,

A Mk 5/1 LR with RG and IR?

Cheers,
Dan

[Mike Cecil]

Yes: the Mk5/1 (an uparmoured Mk5) with the 20-pdr combined with the RG was, as far as I know, unique to Australia, though Australia did not officially list a different nomenclature for that combination, leaving it as either a Mk5 or Mk5/1. Neither did Australia use the 'LR' suffix in the nomenclature to indicate the addition of the rear armoured fuel tank.

The combination of the 20-pdr and RG required a different sight reticle, (among other changes), to the 105-mm - equipped tanks with RG.

Hello Mike, have been following this thread with interest. Living in Seymour and being near Pucka the home of Armour I know many SVN veterans and have spoken today with these veterans from 68/69 1st Armoured Regiment. A Driver said no way was sand used - Fuel was the life line, Mechanic said that in 1968 a .50 Cal round punctured a tank, fuel leaked out and ignited from the burning grass and another fuel tank got blown off by an RPG and due to the mounting bolts being the only thing holding it in place it got blown off and did not ignite. And a tank refueller who said that every night all fuel tanks were topped off with fuel and no sand. They all agreed with your thread about the baskets etc.

In this time they even produced the arourmed protection for the .50 Cal on the M113 out of the track guards from the Cent as they removed them pretty quickly in the jungles of SVN.

Speaking to these blokes who had boots on the ground at the time I would not doubt their recalling of knowledge.

They discounted that in 1968 / 69 that sand was used to fill up the rear external fuel tank. With all of them career Soldiers serving in the unit until the late 80's and that they had never heard of the practice and that fuel was every thing to them.

Cheers,

Dave.

[Mike Cecil]

Thanks, Dave, for checking that out. I'd not heard of filling the rear armoured fuel tank with sand either, but you can learn something new every day, hence my query to Tony.

Tony - have you had a chance to locate that quote yet, please? I've had a quick look in Jungle Tracks, but didn't see it.

Regards

Mike

Mike, just to close the loop, you said in a PM I think that our tank is a rather unique Canadian Mk 5/2 fitted with IR equipment and a 20 pdr. Do I have that correct?

Malcolm

I would love to get a copy of that Mike!
