CF-Firefighter

That’s awesome!! Another cf700. bearings, I’ve seen a few floating around. You can get parts just takes some digging. they are out there still. Just went thought similar with my 865 finding a turbo. Takes some patience and research.

Just a simple observation, I assume that year did not have a battery disconnect? All of the apparatus I’ve been around in my career, Mack’s have had the kussman “spelling” staple black quarter/half turn battery disconnects. In the event I’m willing to bet the field is energized or bleeding power through the generator if nothing else.

Gents, recently put a new turbo on my 865 in my CF795 i need help identifying this turbo flange to get the right parts to build a new downpipe as it is different than the original. Thanks in advance.

Have our departments original 31 Suburbanite in our headquarters building. Still operating. Awesome trucks.

Turbo is a modified BorgWarner 183386 4LE it looks like it will drop right in. The diesel shop said it should out perform the factory turbo. The only difference I see is the turbine housing is quite a bit smaller, but the inlet and outlet are the same size. I was surprised to see how big the factory turbo housing was considering how small of an area inside the housing the exhaust has to flow out of. Basically a 1/4” gap all around the outlet. Might take you up on a used turbo as a spare if this does work out or if I need one because this one won’t work.

Not sure this helps if it’s the same or not. But hopeful the flange of the down pile will be the least of my troubles. I’ll keep you posted when I know of some updated numbers and such.

Finally got the turbo pulled now that the weather is nice. semi local diesel shop that does work for us on our ag equipment stepped up. the Mack turbo was discontinued years ago, can’t get it. This shop found a direct replacement Borgwarner drop in for me. Brand new no core with better mapping. should be her soon. Get the old girl up and going again.

Lost the turbo on the way to a Christmas parade on my cf700. prior to that the braided oil line from the oil galley to the air compressor let loose. figure it’s all related to oil starvation. anyone know about sourcing a turbo for an 865?

That’s awesome! Thank you. They must of spent a lot of money over the years keeping it nice and updating it. Would have been neat to drive with the 5 speed for sure.

Ok that makes sense could be like a filter relocation. Does it crank right up after you have had it running and shut it off? Does it have an electric lift pump or just the mechanical? If electric, turn it on and check for leaks. But places I’ve noticed, hand primer and old braided fuel lines. Just follow the line from the tank, to the filters, to the injection pump. Then check the return lines. Check lines tightness and wetness. Sometimes it’s an air leak and it won’t leak fuel but will suck air. that’s my very limited experience with these trucks I’m still learning. can be a pain to track down

Are you sure those are oil filters? mine has an 865 but they are on the side of the block like most motors. Could be fuel filters or trans filters. From the sounds of what you describe, it could be loosing prime when sitting. If it ran fine before a doesn’t after this winter I’d suspect air in the system. If those are fuel filters, it would make sense. id change them either way.

You are correct, I had it mixed up. My truck had 10 20’s and now has 11r’s.

Hey brother, fulltime company officer in a metro department and also a CF700 owner. I havent seen Daytons on a front line rig in a long time. My truck has the daytons and originally had the 11-20’s. Now it has 11r22.5’s on daytons. Not sure if they are the original wheels adapted. But if you need pictures I can post some of the wheel tire set up.
