2006年8月27日 · The 237 was a Maxidyne, not a thermodyne. Yes it was known as the ENDT 675. It was 672 Cu.In. The numbers are stamped in the block, just ahead of the inj. pump, on that curved area right where the timing case cover bolts on, unless it was originally in a cabover truck, then the numbers could be on the rear of the block, just below the head gasket.

2013年7月31日 · I have been after a R model to restore and the best one I have found (in terms of condition) is a '81 with the 237 HP Mack engine. The truck will most likely be used for local container work (42 tonne GCM). I was after a later model with the 4 valve 300/350 hp but am now keen on this '81 with the 237hp.

2010年3月29日 · A sound 237 Mack engine will reliably output 300 horsepower and plenty of torque with some type of charge air cooling, and recalibration of the injection pump assembly. This is a balance power package and only working with part of the system will not yield the long term durability if this balance is upset.

2009年10月23日 · Good stuff thanks for the info . Tho i was also planning on swapping out the 11.00-20's for 11R24.5's which will bolt right up and clear perfectly, which would then get away from a split rim tube type tire no stock's but can special order to a tire that most truck shops have in stock plus it gains me 5-7mph in max road speed which helps on a 50mph. . .

2005年12月15日 · A member of my family just purchased a 1978 rd600. He was told it had a 237 engine ,5+2 trans, and 58 rearends. this truck has tip turbine aftercooler and I thought only the maxidyne 300 series had tip turbines. I asked if it was a 675 or 676 and he didn't know. So if any one knows if a 237 came ...

2018年9月20日 · I was looking at a 1985 DM dump truck the other day and it had a 237 in it. I figured everything in the mid 80’s would be a 300 or 350. Got me wondering when did Mack quit using the 237?

2019年12月10日 · I would like to know how to raise the injection pump of my Mack em6 237 to 315 horsepower I remember that my engine is from the year 1982 and has an American Bosch injection pump. Jump to content Antique and Classic Mack Trucks General Discussion

2006年2月22日 · I have a 1970 Mack DM685 with a good ol reliable 237 backed by a siz speed tranny. It is a tandem dump and I just love driving the old girl, however most other drivers don't care for me too much when they are following me up any type of hill with a load on. The motor runs great and really doesn't smoke too much when she is at wot..no matter ...
