  1. Hi Guys, My 1961 B61 Mack is the best thing I've ever owned but not for the nostalgia (I was 9 in 1961) or how it performed 23 years ago when I bought it but because it serves my needs today. If somebody would build something as tough and reliable as that old truck I'd buy it (new is nice) but I haven't seen anything out there that does the job any better. I'm not an over the road long haul guy but instead do excavating and the B model and 27 year old DM make me money. It's discouraging to see todays disposable throwaway trucks and equipment full of electronics that screw up and leave you stranded with BIG repair bills. As long as I can still get parts and keep them going, I plan on using the B and DM and make money. Isn't that why we all do this anyway? RS Martyn

    . I could not disagree with you at all RS, my old superdog is worth around $30K here in this country and it still does the job of the 400 hp plus trucks here , and doesnt have any electronics, doesnt belong to a lease company, doesnt have interest rate rises,still gets a cert of Fitness,and doesnt make a hole in your pocket if it is parked up.

  2. why dont you lot get metric , like the rest of the developed world. you are living in the past guys! a 6x4 tractor here in NZ is average at 21 tonnes gross weight legally, even though the manufacturers ratings on the axles are higher, It is just that the government wont spend the money they gather fron Diesel tax and Roadusercharges to put back into the highway network, so therefore the trucks are rated lower to reduce road damage.

  3. Hi guys, I need help with my air dryer on the super dog.

    The governor / unloader valve is bolted direct to my Compresser on the E9, The assembly of the dryer shows a tee off the unloader line between the compressor,but with it bolted direct , how do you get round that one.?

    Im sure there is a clever dick out there who will know.

  4. you people that try and hot rod your engines in this modern era, should get a laptop and a c-15 cat, and a computers for dummies book.

    you only get away with a few mods before all hell brakes loose and your bank account is zero, let alone your rig is not able to earn an income.

    but there will allways be boy racers!!!!!!!!!!!!! :thumb::thumb::thumb:

  5. My 500 started to get hot slowly over a couple of weeks till we found a build up of dirt between the intercooler and the radiator about in line with the fan hub, As the build increased the operation of the fan became critacal, we removed the intercooler , cleaned it thru and blasted the fine build up off the radiator fins and , after that , no problems.

    Just something to keep an eye on, With the pyro, I downshift if it gets close to 490/500.

    that way there is a bit left for a safety margin.

  6. I can send you the 2 parts that make up a coupling, the main tractor part accepts a trimatic from the trailer or a duomatic from the trailer. and there is the end that is connected to the trailer at the end of the hoses.

    you can mix and match then and they are idiot proof, (have to be for us colonials)

    let me know if you want a set. I would say that 98% of new zealand rigs usde this type of Coupling.

  7. Low sulphur diesel is being marketed here in NZ at present , there have been some problems with injector pumps on 4x4s and older cars as the seals have gone hard and leak fuel at the pump, We also have summer and winter diesel mixes. Some of our gear operates in the south pacific islands and when we bring it back down here we have to drain the systems and put our colder mix in.

  8. My superdog is double skinned, and under the turntable there is signs of some heave, I used a hacksaw blade to scribe through the rust until i got a clean gap all the way along the rails then liberally squirted Blackguard into the gap , which is a rust converter, it goes on white then turns to black, That was 3 months ago, Ill check again , but dont expect any more problems, Id loath having to strip the old girl down.

  9. Ive just bought myself a residential warehouse,

    it has a ground floor with a 4.25m roller door and 4mx12m work bay with workshop area to one end , then a n office ,shower,laundry,toilet. Upstairs is a kitchen,living area and bedroom. The superdog looks kinda lonely in there , but im sure a few Mack posters will liven it up, only thing is that it needs twin roof extractors to take the smoke from the stacks when it starts up :P

  10. Here in Nz it was found that engine oil escaped out through the breather as it was mounted on the rear of the valley cover, especially when climbing our steep mountains etc, a modification was isued by Mack , that blanked off the original outlet and a new rocker cover was fitted with a breather unit on it, a bit like the PCV valve that was on ford cars.

    I woundnt say it made the truck go faster though, just slowed the oil down a bit.

    Check your steering arm where it mounts to the kingpin, mine broke off when reversing and the crack had been there a while, around the top kingpin bush.
