TOYOTA MASSY DYNA

OVERVIEW

The truck was also available in a somewhat lighter 3.5ton model, as well as with a longer wheelbase of 3,845 mm (151.4 in). The long model received the QC15 chassis code. The regular version has a wheelbase of 3,445 mm (135.6 in), and an overall length of 6,350 mm (250 in). There was also a short wheelbase model, most commonly built as a dump truck, on a 3,045 mm (119.9 in) wheelbase and with the QC12 chassis code. By 1972 the DQ100 engine had been upgraded and produced 110 PS (81 kW) at 3200 rpm.

HISTORY

The Toyota Massy Dyna is a four-tone medium-duty truck built by Toyota between 1969 and 1979. It could seat three.

The chassis was developed by Toyota, with the Toyota Auto Body subsidiary designing the bodywork. Hino Motors did the work on engine, transmission, and clutch. The Massy Dyna (QC10) was introduced in September 1969.

In March 1975 the Massy Dyna was updated, and its name changed to “Toyota Massy Dyna Cargo”. By the time of the 1979 Tokyo Motor Show the Massy Dyna, never a strong seller, had been discontinued in favour of Toyota subsidiary Hino’s Ranger.

SOME INFORMATION ABOUT THE MASSY DYNA

The chassis was developed by Toyota, with the Toyota Auto Body subsidiary designing the bodywork. Hino Motors did the work on engine, transmission, and clutch. While the Massy Dyna’s name related to the smaller Toyota Dyna truck, also of a cab-over engine design, its mechanics were closer to those of the five-ton DA/FA100 trucks. The doors were actually shared with the larger DA115-series cabover models. Originally it was equipped with an inline-six 4507-cc DQ100 Hino diesel engine, with 105 PS (77 kW). The 130 PS (96 kW) petrol F-series engine (3878 cc) was also in the lineup, a model which carries the FC10 chassis code. The petrol version was mostly used as a fire truck, as its high fuel consumption made it uninteresting for commercial users.

In March 1975 the Massy Dyna was updated, and its name changed to “Toyota Massy Dyna Cargo”. Capacity was increased to 4.5 tons, while the new EH100 diesel engine (still from Hino) was of 5871 cc and offered 145 PS (107 kW). The truck also received a very light facelift: the grille was now painted white rather than black and the headlight surrounds were slightly altered. The wheelbase increased to 4,000 mm (157.5 in), combined with the new engine this meant a new chassis code: EC20. The EC20 also has triple wipers. There was also the petrol-engined FC20, which appeared a month after the diesel EC20. This has the 4.2 litre 2F engine with 140 PS (103 kW) at 3600 rpm. The short wheelbase version (originally FC12/QC12) was now called the EC22/FC22. In March 1976 the Massy Dyna received another slight change, when the fenders on the cab were widened. An extra long wheelbase model was added at the same time.

HOW TO TAKE CARE YOUR TOYOTA?

Preventative maintenance is the best way to keep your MASSY running reliably and reduce the risk of breakdown.

Here are the top ten preventative maintenance tips that we suggest all trucking businesses follow:

1. Check fluid levels: Verifying your engine oil, coolant, transmission, brake, power steering and other underhood fluids only takes a few minutes and is an easy way to avoid major problems. If you see a drop in a fluid level between checks, it’s a good indication that you have a consumption or leak problem and can fix it before it becomes a major problem.
2. Change fluids: The frequency for changing your fluids will depend on how many miles you drive, the weight of the loads you carry and the type of driving you do (highway, dusty roads, city traffic, etc.). Trying to get extra life out of your fluids may save in the short term but cost you big in repairs and breakdowns later on.
3. Verify tire pressures: Any trucker will tell you that tire pressure is critical to check often on your large truck or tractor-trailer.
4. Check your tires: Uneven tire wear can be related to tire pressure issues or problems with your alignment or suspension. Include a check of your tire condition and tread depth as part of your preventative maintenance plan.
5. Inspect your brakes: When you’re carrying a full load, you want to be sure you can get stopped safely. Frequently check your brakes and replace them when they reach the minimum wear condition.
6. Check air filters: A clean air filter can go a long way toward reducing your fuel consumption and helping your engine run more smoothly.
7. Do a battery load test and electrical system verification: If you operate in colder climates, a check before winter is the best way to avoid charging problems.
8. Inspect your gearbox and clutch: A regular inspection of your gearbox and verification that it is functioning properly can help you catch problems as they arise. You will also want to ensure that your clutch isn’t slipping, as this can affect reliability and fuel economy.
9. Check out your exterior lighting: A quick walk-around verification of your exterior lighting helps you catch burnt out bulbs and replace them before you hit the road.
10. Service your fifth wheel platform: Problems with your fifth wheel platform can slow you down and even keep your truck off the road if you can’t securely hook up your trailer.

Every trucking company has a unique fleet of trucks and trailers and needs to adapt their preventative maintenance list to suit their situation. Including these ten tips in your list will help ensure your trucks run more reliably and are less susceptible to breakdown.
