BRDM Driver Posted June 7, 2014 Share Posted June 7, 2014 Just got the Scorp out of the garage and it only steers one way. The left hand steering tiller is just flopping about. Tried breeding the right hand caliper and checked the fluid level. Is this going to be the cylinder seal? Odd that it's not leaking, just suddenly providing no pressure.

BRDM Driver Posted June 7, 2014 Author Share Posted June 7, 2014 Looks like a stuck piston in the master cylinder! Quote Link to comment Share on other sites More sharing options...
robin craig Posted June 8, 2014 Share Posted June 8, 2014 Perhaps this is the appropriate time to mention something. Recently I was in the presence of a number of ex service members who had all been Drivers and instructors in doing that on CVR(T)s. It was very interesting that after getting the vehicles running all of them, before moving the vehicle forward, did what I now call the CVR(T) wiggle. They did a quick small neutral turn effort left and then right just to prove the steering works. I know I will be adding that to my start up procedure R Quote Link to comment Share on other sites More sharing options...
BRDM Driver Posted June 8, 2014 Author Share Posted June 8, 2014 (edited) Yes, I will do the neutral wiggle from now on! Finished at 11pm last night and had a successful run out to Lulworth Castle today for the Wessex classic car show! Both pistons had a load of crud between the first rubber seal and the piston where they had been sat in about an inch of water some time ago (before I owned the vehicle). Typical case of a seal that lets just enough water in to start the rust process and keeps it there for years....

Tiffy_massive Posted June 15, 2014 Share Posted June 15, 2014 Unfortunately vehicles are not well looked after when awaiting disposal. I have noticed over the last few years that Vehicle Specialists (i don't think they are very specialist at all) who are responsible for looking after and moving vehicles in depots have a tendancy to leave hatches and louvre covers open when leaving vehicles parked up. CVR(T) are really prone to this is left outside with the louvre covers not closed over with the canvas covers fitted to decks. Having belly plates fitted then compounds the problem as the water just builds up. Some years ago while trying to unload the vehicle train in BATUS Canada we had to light fires under the majority of CVR(T) platforms as the VS had not closed hatches or covered louvres. The rain had built up in the hulls to about a foot in depth which had then iced over in the -40 Canadian winter meaning we could not start the vehicles as flywheels etc were frozen in the water. Ended up getting some started and having to split tracks on others and drag them off on their wheels. Quote Link to comment Share on other sites More sharing options...

A couple of the CVRT I am re-building have suffered frost damage, The torsion bar tunnels have filled with water, then got frozen at -40 and the casings blown and cracked, the tunnels go from a flat top to a dome shape, and crack at the ends.Have you ever seen this before??

robin craig Posted June 16, 2014 Share Posted June 16, 2014 That is some major freezing like a typical Canadian winter cold. We often see metal structures improperly built suffering damage like that out here. We had a Canadian Forces Supacat FLPT that had the data plate put on twice and the original rivet holes were not filled and water got in and froze and swelled the hollow steel section very nicely.

Sidewinder Posted June 16, 2014 Share Posted June 16, 2014 My Spartan has the first torsion bar tunnel that runs through the gearbox bay domed in that way... I've been trying to figure out what might have caused it for the past two years! Suddenly makes sense, thanks for answering the mystery! Apart from blowing the casing, is it likely to have done any other damage worth keeping an eye out for? Cheers, James Quote Link to comment Share on other sites More sharing options...

Cheers, James Hi James, Yes this is the same spot on my CVRT Samson that I am restoring, the gearbox bay tunnel. So next job is to drain the water out of all of the torsion bar tunnels. About 20 years ago I was looking after a closed down Mill, there was a very hard frost for about a week, and the factory pipework , boilers, valves, heat exchangers, etc up to 1/2 inch thick steel was completley destroyed.They demolished the factory in the end.

Tiffy_massive Posted June 16, 2014 Share Posted June 16, 2014 Water can cause all sorts of issues to be honest. One of the other ones is where water has semi-covered rubber seals that have then been damaged when the water has frozen and expanded. I have seen the rear G/Box mount buckled by ice while on the CVR(T) line during the Winter Repair Prog. Common problem that we could not work out to start with but got there in the end. Another problem was that to repair it correctly the hull had to be temp controlled for at least 24 hrs before and i think it was 76 hrs after the repair in order for it to harden correctly (i am sure someone will be along to correct my figures if they are wrong). It was not relaised for a while that it took so long and hence repairs done correctly but not given the full cure time would fail fairly quickly.

I worked out the water entered the CVRT Samson gearbox torsion bar tunnel via the bolts fixing the steering brake tubing to the torsion bar tunnel, bolts were loose or missing, hull full of 12 inches water, water enters torsion bar tunnel via missing bolts,serious frost , then damage. Easy to fix problem, providing vehicle is not to be used for comabt. Quote Link to comment Share on other sites More sharing options...
