    JAGUAR MARK II – THE ORIGINAL GENTLEMAN’S GETAWAY CAR

    The Jaguar Mark II is most famous for its use in bank robberies across the United Kingdom, the 3.8 litre Mark II was the fastest four-door in Britain and one of the fastest anywhere in the world. This made it ideal as a getaway vehicle for 4-5 adult males and their canvas bags full of Her Majesty’s finest paper bills.

    Oh thank goodness..... now I can sleep at night.!!

    It is always fun to get something going again after others have given up.

    Fortunately this was mostly time and bull headedness.

    Spent some more time playing around with the D4 yesterday and also reading through the manual.

    First thing was change the oil in the pony motor.

    One thing I'd wanted to do was check the valve clearances. When I picked up the thing it had a bit of a miss at idle, where every now and then it'd miss and then rev back up. It'd do this about every 5 seconds or so. Interestingly it's not doing that at all this season - so having fresh diesel with a bunch of Power Service Diesel Kleen in may have helped un-gum some stuff in the fuel controller. Still, I had the hood off the thing from messing with the pony motor and thought this was a good time to check it. Here's a video of me letting it warm up before checking the valves:



    This dozer had smoked some, especially at idle, even though it ran well. And I figured who knows when the last time the valves were checked, may as well. Good thing I checked them! Clearances were supposed to be 0.010". A few valves were loose, but about half of them (more than half I think) had zero clearance at all! Not good and probably means those valves were actually being held open a hair. After doing the adjustment the idle smoke stopped and it definitely seemed to run a bit more evenly, although as a Cat, it still ran and sounded good. I love the sound of a proper old diesel.

    In the video you'll note some smoke coming out around the exhaust manifold. There's a flange there that is on solidly however there's a gap in there and it seems that whatever gasket may have been there (if any) is missing and/or blown out. I figure the best way to handle this is probably going to be some exhaust seal putty to put on and just see if that can seal it up well enough. I've had good luck with that stuff before in the right scenario.

    When warm the dozer seems to have around 20 psi of oil pressure, maybe a bit less. The manual says 30 psi is what you should have. Since who knows how old the oil is on there, I figure it's time to change it. Cat recommends 30 weight oil, but I figure I'll go with 40 weight to try to get that oil pressure up a bit. I haven't bothered to find/check the hobbs meter (who knows if it even works). This thing is 70 years old or more, very well could be the original engine - I think it's entitled to be a bit tired. But it still runs well and I'm not too worried about it.

    Another thing I'm going to do is go through and lubricate all the lubrication points on the thing. There are a lot of them! Most take just motor oil, but I also need to get some grease on my grease gun and hit the zerk fittings. I will also check and maybe replace the oil in some of the other things, although for the non-engine components I'm less worried about the age so long as it seems to be in good condition and not filled with water.

    Some may recall that last year I purchased and rebuilt the hydrualic hoses going to the ram. They seem to be functioning correctly, no leaks!

    It really is a neat machine, and has tolerated sitting very well.

    What I find really neat is how many of these old things are still around, working, and doing work. Granted I'm the only one to walk into my local CAT dealer asking about a 1950s D4, but I'm certainly not the only one in Kansas who has one. I figure I'll go in and ask about some of the bolts and nuts for the tracks in a few days and tell the guys what I've done to it.

    Think the folks in the CAT media department would be interested in a story about getting an old D4 back up and running after sitting for 10+ years and using it to build a runway?

    Maybe. I will ask my Comms guy what he thinks.

    Did you get me a serial number yet??? ;)

    Ha! No, I didn't. But I need to. I'm really bad about that. :(

    If the comms guy is interested, feel free to put the two of us in touch, I think it's a fun story. Besides, could maybe get some extra publicity for Cloud Nine, and the fact that I bought my wife a bulldozer as an anniversary present (and she loves it) is pretty unusual.

    I am going to guess that they will want you in the process of making the runway before they do anything. But I will work the phones and see when I am back in the office next week. If anything I could probably get you spotlighted on the engine side of things since that is my area of the business. I assume you are running a D4400 in that dozer. Am guessing it was manufactured in Mossville, IL or East Peoria but I will have to do some research.

    They did a story on a couple that got married and rode off on a dozer. You never know. :)

    We technically are already in the process of working on the runway and expect most of it to get done over the summer. I've started using the dozer to push out tree stumps. After that, I intend on using it (as the most qualified vehicle I have) to pull the sheepsfoot roller I bought last year to break stuff up. The dozer will be the primary piece of equipment used for the runway creation, despite my collection of other tractors.

    I’m doing a small block Ford in the Cobra, but an idea I’ve had for a long time is building a car around a Detroit Diesel 12V71/92 or 16V71/92.

    Tractor Supply has some straight 40 Rotella that I’ll probably buy for the engine, and this weekend I’ll look at lubing things up on it.

    Today I went out to the dozer with my manuals and went over the lubrication points, at least as much as I could. Really I was overall surprised with how well things were lubricated on the whole. I’d already changed the oil last weekend (still have to change the filter). I filled up the final drives (those were both low and took a good bit), filled up the fuel pump (which is oil lubricated and was dry), and I lubricated all of the 400 zerk fittings.

    The PTO on back was full but extremely milky, so I drained and refilled that. The drain plug/magnet has a bunch of rust in it (no surprise) so that’s probably a negative indication about its potential longevity. I also don’t use the PTO much at this point, somewhat doubt I will, and I’m not taking anything big apart like that.

    The transmission was also milky but not as milky. I ran out of differential/gear fluid so I just left that for another day. The hydraulic fluid is milky and I should drain and refill those some day before too long.

    Some of the rollers and idlers that need grease looked full but the grease was old. Another day I might try to flush that grease out with new.
