a little advice here , install a remote kill switch ,the last thing you want is some little person starting your jeep only bad things happen after that , as Rob said keep great control over who and how people get in your vehicle, things will get broken or go missing, and if you own a rare MV that is very bad, we had a issue at the first Georgina event with kids standing on the WW 2 jeeps and on the windshields , bottom line is keep people out and off your vehicle , you want them to show the same respect to your vehicle that they show to the shiny Mustang, if one of those little darlings gets hurt who do you think will be in great pain after, and if they start playing on one vehicle soon we need to deal with a free for all,

Indeed, the public treats the MVs entirely different than any other vehicle at a car show. I have had kids climb up the nose of a CMP (while the parents stand there watching), and kids (and disadvantaged cultures, while drunk and high as kites) jump into the vehicles without asking. Like ants at a picnic, they will constantly be searching for a weak spot in the defenses. Opening and slamming hatches on armoured vehicles is fair game, and what kid doesn't want to know what happens when you pull that red handle (AFV extinguisher). If you lock up an armoured vehicle, but have a hatch open 8 feet up, then obviously that is an invitation to climb up the sides. And why can't a family of 5 walk up the trails of a gun so they can get into the back of a deuce and a half.

To that end, when I display the museum vehicles or even my own, it's almost always with rope and stands so there are some boundaries. Even then, should the ropes somehow sag to less than 8 inches from the ground, then obviously that means "come on in".

If there is a level of interactivity with a vehicle, then it is strictly controlled. We will rope off a M113 but have the ramp down for an entrance. We allow the kids to get up into the drivers hatch and hold the back of a 50 cal. But it is controlled like a circus ride.....2 people run the display. One at the back of the vehicle limiting the kids to 4 in the vehicle. They get in, sit their butts onto the troop seats, and slide down until it is their turn. The second person tells them how to climb up without hitting their heads, slaps a helmet onto their head, smile and thumbs up to mommy who is taking the picture, then directed off and out the back of the carrier. There is no chinups or swinging from the hatches, a glass partition separates the kids from the drivers seat, no walking around the roof, no testing to see what this lever does (answer: it drops the other kid already up in the seat back to the floor of the carrier whilst shearing the other kids finger tips off).
We will have 30 kids lined up for that 10 seconds behind the gun, and some come back 5 times to do it again, so the thrill is there, but just with safety.

Your vehicle, your choice. But allowing the little angels, hopped up on sugar and with exhausted parents who are looking for a way to hand them off to someone else, free reign on your vehicle in no way promotes history or respect.

YUP!

This weekend the Cold War Collection attended the local country fair.
1) Some youngster swiped the master key to a Pinzgauer. A short run back to the garage returned with a spare. Almost every vehicle has at least one additional power cut-off.
2) Having an overhead sun/rain shelter worked well for crew comfort.
3) We have worked out a couple of crew positions for maximum visibility and to allow visitors (kids, moms, and dads) to get the experience.
4) I wipe oily surfaces often and especially before opening to the public.
5) The V100 has split doors which control foot traffic but let parents see inside and photograph little Johnnie wearing the M1 helmet shell or goggles.
6) I have some J-hook magnets and 550 cord to string across openings as another limiter.
7) Earlier in the year we had a kid spin the starter on the V100 - quite unexpectedly! I ordered him out, but the youth's grandfather is a retired colleague of mine! So I had to quickly investigate and form conclusions. Fortunately grandpa is a retired freefall parachutist and recognized the language I had to use. No, I was being safe by being firm, but yes we could have isolated more circuits for the next time. It is added to the checklist.
8) When there are too many little fingers touching things inside and around the cupola gears, I will set the travel lock. We don't want to use up the collection's insurance coverage in one shot on one claim. For more teachable visitors, the locks can come off.
9) The driver's hole on the CVRT is always out-of-bounds.

Finally, I was very impressed when one local beauty in shorts, tank-top, sandals and purse, stepped off the ground onto the step stool, onto the CVRT's wading skirt shroud, onto the deck, reached in and extracted some obstreperous child from the turret, backed off and only lost the ash off her cigarette on the last step.

I put a M113 out for display with almost dead batteries. Feeling that there could be no issue with the kids managing to start it, I left the batteries connected (I no longer do that).

Later, while walking by the vehicle, I noticed a large puddle of bile next to the vehicle and had trouble figuring out what it was. It was then I realized the little darlings had managed to find the full combination of master switch and bilge pump switch, and had bumped the forward hull out onto the parking lot. Luckily nobody had been standing there. They also had pulled the tiller bars off...luckily the vehicle had not rolled forward.

In the end, I considered it a learning experience. As I mentioned before, the drivers position is separated by a sheet of plexiglass, and just as often as not I stick a mannequin in uniform into the driver's seat to prevent the little explorers from climbing up through the hatch and into the drivers hatch. After all, the glass is just a detour and not an obstacle. Mind you, there is a slot for the ramp release lever, and the little arms reach in as far as they can to explore.

Hi Rob, Terry & Frank....thanks for your comments as per car/military shows....yup....chalk it up to lack of experience with kids at shows...I have learnt a lesson......however, disaster has struck.

Rob....while taking the jeep out for a drive (30kms) on the way home about 500m from home there was a loud ping and I started to loose coolant. I got home well enough but once parked saw that coolant was puking from the water pump puke hole. I called Brian Asbury about 100kms from Barrie and he has a 3 pulley rebuilt water pump so I will be picking one up along with a new thermostat and gasket. At the same time, I will have the rad flushed to clean the core. Any other things that I should do while having the rad & water pump off?

Question....hypothetically, if a chunk broke off of the water pump vanes ( I did hear a metallic pink before the coolant puke)....is it still safe to drive 2-3 kms to a friends house to have it repaired?...my garage is way too small.

Also...back to the shifters, where do the two 4x4 shifters (in/out & high/low)have to be to be able to drive the jeep in two wheel drive?....at times, with the jeep in first or reverse, the jeep does not move after I let out the clutch and I have to play with the other two shifters to get the jeep to move.

Lastly, I put a finger into the tail pipe and its very black and sooty and from what I understand, this may be due to a rich carb...any possible adjustments that I can make? I have not looked at the plugs yet but the jeeps starts first poke/prod and then runs well until shut down.

Best regards and let me know when I have to start paying repair consulting fees.

It's your Jeep, so expose it to as much abuse as you would like. A blown water pump is not a disaster....that's just normal maintenance for a 50 year old vehicle.

I would be very surprised if you could hear a water pump vane break. But if the water pump bearing is shot, perhaps that is where the noise came from? If there a lot of play on the fan?

I would suggest topping up the rad with water and leaving the cap off for the couple mile trip. I have seen too many Jeep blocks crack in the center between the #2 and 3 cylinders because of overheating. Unless the leak is of biblical proportions, you should be OK. Your temp gauge will tell you, however they are slow to report if the coolant level is very low.

Shifters: Normal driving. First lever on the transfer case (2-4wd) is all the way forward....it should just about hit the defroster deflector lever. Second lever (H-N-L) is all the way back. There should be a little data plate nearest you on the batch of data plates showing the shift patterns.

Better rich than lean. A cold engine can cause what you describe, leaving the choke on, or merely setting the mixture screw. With the engine hot and running smooth, turn in the mixture screw until the engine starts to stumble. Do not jam the screw all the way in. Now back it out until the engine reaches it's highest idle.

Hi Rob....thanks for all the replies to my inquiries. Before I reply to your answers one by one I will say that I met with Brian Asbury....I bought a rebuilt 3 pulley water pump from him this AM as well as several other parts....he had nothing but good things to say about you....I will move on.

1. The old pump came off easily...looks good-no vanes/impeller blades broken and there is no play between the vanes and the pulley....in short, it turns fine with no growl. OK....so what made the loud ping noise (just like a M1 garand clip leaving the breach) before the coolant let go through the puke hole?

2. I did not take it too a shop...after 20 years not wrenching on my vehicles (with the exception of wiper changes, oil-filter changes, diff/tranny fluid changes etc) I got down to it with my wife and everything was off, cleaned and paint prepped to be put back on in 3 hours. I will however bring the rad into a rad shop to be cleaned & flushed as there is a lot of brown-grey sludge in and around the core. Question-when I took off the thermostat housing to replace the thermostat....there was none.....why?...what are the ramifications? and how may it have effected the longevity of the engine?

3. Yup...got "all" the data plates including shift patterns but it does not show shift pattern for normal 2 wheel driving ...so for normal driving the 4x4 in/out shifter should be all the way forward-to the dash-firewall (OUT) and the second shifter (low/neutral/high) should be all the way back-towards the seats (HIGH)....right?
I am asking because I have lots of play in the 4x4 shifters and at times in 1st or reverse the jeep will not move once the clutch is engaged but if I play with the 4x4 shifters it will engage......so, once the jeep is put together, I will try it as you wrote it and see if the main transmission shifter will engage in 1st once the clutch is engaged.

4. Rich or Lean? OK....firstly, the jeeps starts first time every time and runs well without a choke start up.....but it possibly requires a leaner mixture....where is the mixture screw?

I was wondering if you can reply in point form as above.

So....out of all of these inquires, the most intriguing is the loud metallic ping and then the coolant puking fluid even though the old pumps looks and feels good. Any thoughts as the wife is now hesitant in future drives in the jeep.

I can't explain the pinging sound....likely a red herring: unrelated to the fault you did find. Heck, it could be a 1/2" wrench you left on the skid plate finally fell onto the road.

The lack of thermostat is not ideal. But it normally leads to condensation in the oil (especially at low temps. I recall seeing what looked almost like a film of whip cream on the dipstick in the winter time). As well the engine will not fully burn it's fuel at lower temps. Perhaps that is why your tailpipe is sooty.

Levers should be like you say. They will rattle around if the little spring clips are not slipped between them and the bracket they mount into. If they are popping out of their gear, then you have some transfer case repairs to do.

The mixture screw is located at the bottom inch of the carb, pointing towards the heater. Look for a screw with a spring between the screw head and the carb body.

Can't help on the wife thing. I just kept trading up until I found one who likes/tolerates my toys. Even now she can complain a little too much on a cruise night.
