Get A B30x Running After 40+ Years

Recommended Posts

I am about to get a 1956 B30X Dump, Maxidyne 6 cyl gas 331, 5 speed transmission, standard cab running after 40+ years.

I am looking for advice on what to inspect, clean, rebuild before I try to start her.

My thoughts are to: pull plugs, put some light oil in the cylinders, hand turn the engine (later), inspect the points, clean the gas tank, clean gas lines, add fuel filter, inspect and test thermostat, replace oil filter cartridge, and clean cartridge container, replace engine oil, remove / clean / test carb., clean air filter and service, replace transmission fluid, grease fittings, oil cables and get them moving or replace, replace coolant, pressurize and check for leaks, new battery. Then hand turn crank a few turns. If it turn then try ignition and starter.

What am I missing?

Sounds like you have a very solid plan going there.

Can't really add too much too it.

Remove and replace fan belts. While the belt(s) are off, turn by hand your water pump, generator, idlers, and check for play, looseness, roughness of bearings, seals.

When you remove the carburator, make sure there are no wasp nest, dirt dobber buildups, etc. below the base. If your air filter has been left off for an extended period of time or have no muffler and a short exhaust pipe, dirt dobbers will travel and build.

I helped my father in law work on an old 1930's International 4 cyl. gas saw mill motor that had set up for years. It was an overhead valve engine and I took the head off to find dirt dobbers had built in the intake and exhaust ports and even through one cylinder where a valve was open!

Bob, is that your truck in your Avatar? I've a big soft spot for dumpers!

Was going to say check radiator if you were planning on running her for an extended period but saw you were pressurising and checking for leaks so I'll just shut up!

Good luck with it, let us know how it goes.

Thanks! I thought of the belts after I wrote but all the items you mentioned are very important.

The picture is one of the trucks I bought, but the picture was taken in 1961. I bought 3 at one time, all B30 dumps. One is rougher than the other 2 but all have good metal. They went out of service around 1964. I plan to clean one up first and use it, not restore, but keep original so if I do restore later it will be in good shape. If I have time I will clean up and protect the other 2. Thinking of body work, paint, windows and seals in good shape.

Did I see you are from Australia? Just got back from a vacation there. Wonderful!

Bob, yep, I'm in Australia. Where did you visit?

Cairnes, Sydney, Melbourne, Cairnes and long trip home. Did not get to the Western Territory. Met one couple from close to Perth. A wonderful trip.

Sounds like you covered some ground. Did you see any of our Bs?

I saw one pulling a double (pretty common there) in Melbourne down by the beach. It had that nice rack on the front like yours.

On a somewhat unrelated topic: I received a wonderful packet from Mack Museum yesterday in response to a request for manuals etc. WOW a service manual, owners manual, records of when the chassis was put together and more .... Valuable documentation!! It will make things much easier to get these babies back on the road.

Thanks for staying in touch.

You might want check for slugde in the bottom of the pan when you change the oil. I have a 1951 IHC L-212 that was driven into the garage in 1969 and never touched again until 1994.

Not consecutive serials, 2 are very close, don't have the info with me as I write. 2 are B30X's one a B30P. Mack museum had the build sheets on them; dual reduction rear axles. Thanks for writing.
