On a weekend activity a friends FV102-Striker suffered an engine failure.
We subsequently swapped out the engine for a second-hand unit the owner had on hand.
The following are the images of the engine when it was stripped. :'(
-
That engine looks to be in terrible condition even before the valve failure. All the pitting on the piston crown, possibly misfiring maybe.
-
No that was a piece of valve bouncing around in the chamber at 3000rpm before bits of it migrated to cylinder no 2 and even no 3.
-
Yep and there was a head gasket leak. Combustion flame was to cold. Coolant was in poor condition for a long time. At least it won’t blow smoke anymore.
Looking at the oil return in the head there’s is a difference between intake and exhaust side meaning there is an oil pressure issue that was exacerbated on that valve stem first being the last one being feed.
On the bright side. The head can be repaired unlike the piston. Don’t forget to measure the big / little end spec.
A sad thing really…
-
BTW that plug reach seems to short.
-
Will be cheaper to get a full rebuild crate engine from the U.K. than to rebuild this one.
The engine didn't have that many hours on it. :'(

That was after we panel beated the plug, when we took it out of the engine on the day of the failure, the electrode was bashed across to one side.
Not even sure if the plug was fully screwed back in, was only there to keep muck getting into the cylinder.

I think you have a good point. I would just come down to freight...

Those motors are for spares or rebuild/repair Philthy :(

Tommy, your quite right, sucked in by a lick of paint!
Could they not import from a 1989–1993 Dodge Ram that had the later Cummins engine.
Like this one http://www.ebay.com/itm/90-Dodge-Cummins-12V-Engine-5-9-First-Gen-Complete-12-Valve-91-92-93-140k-Miles-/151627482355 (http://www.ebay.com/itm/90-Dodge-Cummins-12V-Engine-5-9-First-Gen-Complete-12-Valve-91-92-93-140k-Miles-/151627482355) there has to be more choices out there besides they would have a larger parts pool to choose in time to come.
The pressure is off because they have another Jag. Engine so they could buy well.
No such thing as too much Hp. unless you’re the gearbox, is that right that they had a centrifugal clutch?

Its really awkward hanging upside down in the hull of those things undoing all the bits to remove the engine.
What I don't know is why couldn't they have added an extrs 25mm in the engine bay so that it wasn't an hour's battle getting the replacement engine to drop down into the bay so it could be reinstalled? >:(

That plug is a spare from my ferret although it did match in length the broken one that came out.

Diana,
I am thinking that if you thought changing the engine was a struggle then you did not remove the right hand sidewall from the drivers position. I worked on these from the early 1980's onwards and the few minutes it takes to get the seat and sidewall out saves much more time and effort doing the job. The CVR(T) engine was one of the easiest engines to change in the Britsh Army fleet at the time. Try a CVR(W) Fox, now they are a trial.
Broken valves on these are caused by over revving and kissing the piston, another well known failure was a rod through the block.
regards, Richard

Hi Richard
Are you talking about the sidewall of the engine bay on the LHS of the driver?
That was almost the first thing we removed after the engine covers came off, the problem was that the engine was touching the lip on the partition between the engine bay and radiators and the rear wall of the engine bay at the same time. twisting the engine sideways or tilting it only seemed to make it worse so we had to lower it mm by mm.
We did some work on a Fox (Scorpion Turret) but not a lot. The biggest problem of that was the regulator box getting it to work, at least the regulator box in the Vixen (same as the Fox). We even swapped the box from the Fox to the Vixen and then both stopped working! >:(
Have you ever worked on a Vixen? I believe this one is the only operational one in the World, AFAIK even the one at Bovington isn't working.

Diana,
We also used to take out the front bulkhead, that way it made it easier to access the drive shaft, again, not a lot of extra work, but makes like a lot easier.
Re. The Vixen, I sent a lot of info for the Fox regulator panel to Col quite a few years ago after he spoke to me about the problems. The Vixen was not pursued and development cancelled early on, I worked on Fox from when it entered service around 1976 right through to its demob around early 90's, plus a few in private hands in later years. Only one good thing about them was driving them, but working on them was often trying, power steering unit for instance. Don't volunteer for that particular task!!!

Hi Richard
Have been absent from the forum for most of the weekend.
I looked at removing the front panel, but with all the harness and other connections it looked like more work than benefit.
The replacement engine Col sourced had a different arrangement of the exhaust "Y" connection after the flexible joints. The replacement bent 45 degrees while the Striker one bent at 90 degrees.
In relation to other CVR(T) like the Scorpion. Would you know if the engine bay rear wall get moved forward in the striker to make more rear compartment space to accommodate the spare missiles and therefore the reason why the engine lift/install was so tight?

Hi Diana,
The J60 engines in all the CVR(T) range that I can remember were tight to the bulkhead at water pump end of engine so doubt there is any dimensional difference in length of engine bay. Removing the front bulkhead is not a difficult job and will save time and effort in the long run. There are often short cuts to any job, but they can lead to other problems, like difficult access or damage, and it is not as if you are in the battlefield.
Not sure about the Y branch angle, it could be from one of the different height hulls, ie. Samaritan and Sultan are the highest and Scorpion / Scimitar / Sabre are, I think a bit lower than Striker / Samson / Spartan. Only a matter of swapping over though?
cheers Richard
