As for the tracks, I would flood them with diesel (cos its cheap) and take her on a long pull up a bitumen road.

Diesel to soak through the surface adhesion. Let it evaporate (or burn it off if there aren't any combustable pads or bearings or roadwheels, and if you feel adventuresome ... . Then flail away with a hot torch and 5lb sledge.

Hi Ryan - an old proven method of freeing rusted parts is to put them in a bath of molasses. It is a slow process but you will know if it is working if you get a lot of penecillin on the surface. Your main problem will be to get the tracks into some sort of container, but trust me, it will work. If you go back to my thread on electrolysis derusting in 2004, you will see several posts on molasses. There is also plenty of advice on Google.

Yep will slip right off the truck on all that molasses

Unless the tracks have been changed to a non-original type, all of the Grant and Sherman track, whether rubber faced or steel use pins with rubber doughnuts pressed into the links. Therefore, they cannot seize as they do not move beyond the rubber limit to start with and if you soak them in diesel, it will eventyally destroy the rubber.

If it is original style track, it is likely the brakes are stuck.

[Ryan]

Once again thanks for the advice guys.
Adrian, here's a couple of pics of the tracks. I'm pretty sure that they are original. The tank I'm now told has been sitting in the same spot for between 10 and 20 years.
Bob I'm not sure I'll find a bucket big enough to fit the tank in.

Nice tracks Ryan, looks like fairly good rubber on the wheels too. Well done. Does it have an engine fitted?
Regards Rick.

[Ryan]

Hi Rick, no it doesn't have an engine fitted. Just a big, stuck garden ornament.

[tankbarrell]

Ryan, that's T49 track and it will not be seized. It is, as is all other M3 track, rubber bushed so it will be a brake or transmission issue.

Well Adrian's right (as usual) - the track frames for that style of track still have rubber donuts in the guts, so your problem moving it is not seized tracks - if it were a Matilda or Valentine or Bren Carrier then yes they rust up.

If anything in the bull gears or tranny is jammed then you may have to split the track front and rear and anchor the top track in place so it doesn't damage anyone and tow the hull onto a float. Then try and drag the remaining two bits of track up underneath the hull onto the floor of the float so you can get it home. Splitting it after all these years is the next problem as you probably don't want to cut it cos then you need some bits to replace it. Phill and I know a chap who winched (dragged) a Grant hull onto a float and then had to get it off later. Heavy metal can slide scarily easily on a steel deck but the owner of the float may not be interested.

Can you post some pics of what's left inside both engine bays and the rear of the hulls at some point so we can try and help identify what engines they probably had?

As far as I can gather, depending on the manufacturer there may be a number stamped into the top edge of the towing eyes at front and rear of the hull. I've read that only 1 in about 3 manufacturers did this. Since many of these did a lot of towing in private use the towing eyes may instead be mutilated. If the diff housing has been swapped out then the numbers would be different front and rear.

If either of the hulls is a Petrol radial then it has twin doors or at least a square opening you can step into at the rear. Look centre top edge of that back lower hull corner casting and there might be a number stamped into it with letter punches - I'd be interested to know what the number is cos I'm trying to find if it's a part number or whether some hulls had their number stamped there.

Hi Ryan - firstly the seized track. Depending on how much room you have on your property, you could dig a tranch to accomodate the track. Line the trench with heavy duty plastic sheeting and then immerse the track in the molasses solution. Ensure the plastic wraps across the top of the solution to stop it evaporating. It would be better with the tracks off the tank but you could do the same if they were still fitted. You would need to dig the trenches underneath the tank and then lower it into the trench. This however would only do the lower portion of the tracks.

Secondly the rubber donuts. If you need new ones, the industrial rubber factory I get my Carrier wheels re-rubbered should be able to manufacture new ones providing they obtain a template. The only problem I envisage is whether the donuts were inserted between the links when the tracks were assembled or whether they could be inserted after market.

Well Ryan,

If you need some extra parts here is your chance! http://www.milweb.co.uk/classifieds/...ad=57706&cat=1

Cheers,

Cheers for that Marc but shipping would be a killer!! It'll put my crane costs to shame. I reckon if I look hard enough I'll come across a Grant upper hull over here.

Hi Alex, my mistake. I thought by the photos that the bogies may have been attached to a frame and welded. Just seeing things that weren't there. Interesting reading about your mystery bogie. Any pics?

[Bob Moseley (RIP)]

Hi Ryan - don't hold me to it, and you may already know, I believe John Belfield has some of these. However he may be hanging onto them to finance another superannuation.

Hi Bob, I haven't tried JB yet and a probably wont. Feel I want to blaze my own trail a bit. I like the hunt too much also.
On another note I visited Jeff k while I was in SA to look at his collection. Great bloke and some nice stuff. Thanks for the connection.

Ryan, Have you contacted Bill O'Rielly yet? Bill has nearly finished his Grant and has a few wrecks around. He's in the VMVC and they are having a run to his place soon.
Rick.

[Ryan]

Hi Rick, no I haven't. His name doesn't ring a bell. If you have told me in the past about him I'm sorry as it must have slipped my mind. I'm not in the VMVC, the GMRG or the KVE for that matter. Kinda silly I guess. Is Bill over my side of Vic or your side?
