smorse54 Posted November 13, 2012 Share Posted November 13, 2012 We are almost finished repowering this R-608 pumper with a ENDT-675(237). The original 707C gasser had a burnt piston and scored cylinder walls.We had no luck finding another 707C so discussed it with owners and decided on the diesel. Her are some pics: Quote Link to comment https://www.bigmacktrucks.com/topic/28318-r-608-f-repower/ Share on other sites More sharing options...

smorse54 Posted November 13, 2012 Author Share Posted November 13, 2012 Thanks guys. With the rear ratio it figured about 50mph top speed.Was acceptible to fire dept.This is still a working truck by the way.The radiator is from an old R model tractor. Both tanks were repaired(new corners tigged on, tapped holes helicoiled) and a new 4 row core from Detroit Rad. installed.The polished alum. came from a spray can.I'll get mor pics when it's complete.

smorse54 Posted November 14, 2012 Author Share Posted November 14, 2012 Vinnie, the truck is a 1972 if memory serves . I'm not sure of the engine. I know it's an early 237 'cause it has studs and nuts instead of head bolts.I will check for sure on both.By the way your U Model is really looking good.Do you have a gold bulldog for the hood? 1 Quote Link to comment https://www.bigmacktrucks.com/topic/28318-r-608-f-repower/#findComment-145939 Share on other sites More sharing options...

j hancock Posted November 14, 2012 Share Posted November 14, 2012 I am not a fire guy but is this diverting water from the water tank to help cool the engine while it is pumping?

smorse54 Posted November 14, 2012 Author Share Posted November 14, 2012 Yes, that's a pump heater. There's a copper coil inside of the housing. Engine coolant flows thru the hsng heating the pump water in the coils that circulates from and back to the pump. Supposed to keep the pump from freezing in cold weather.

SteveRight church; wrong pew. The coil is designed to keep the engine cool when pumping for long times because of a lack of air flow through the radiator. I think you will find that there is pump (raw) water in the coil, not anti-freeze. Make sure it is drained in freezing weather.

bulldogboy Posted November 15, 2012 Share Posted November 15, 2012 If this is still an in-service fire engine a diesel engine should extend its life for quite a few years. Fire engines have a valve on the pump panel to allow water from the fire pump to circulate around the engine to keep it cool while pumping (as fxfymn says). At least the "L" and "B" models that I operated did; not sure about these new fangled computer controlled engines. bulldogboy Quote Link to comment https://www.bigmacktrucks.com/topic/28318-r-608-f-repower/#findComment-146072 Share on other sites More sharing options...

smorse54 Posted November 15, 2012 Author Share Posted November 15, 2012 Hey guys, sorry for passing along the misinformation.We had a discussion at work whether it was to heat the pump or cool the engine so we called on our resident firefighter who settled the disagreement by telling us it was to heat the pump.Wrong answer.Glad I got set straight.I'll let everyone know at work tomorrow.Yea, I know it looks like an ISX,but got to carry on the firetruck thing.Steve Quote Link to comment https://www.bigmacktrucks.com/topic/28318-r-608-f-repower/#findComment-146087 Share on other sites More sharing options...
