any progress/pics of your swap?
-
don't recall seeing W model tractor with this long wheelbase. possible 5th wheel installed after the fact?
-
I see some e6 and em6 engines for sale. most have side mounted turbo but once in awhile I see one with a rear mounted turbo. were these model specific and if so which models were they made for and why?
-
hey paul I almost confused it with a ford pantera!

Most of the inline six Mack diesel engines I've pulled are right at 1950-2000# when near fully dressed. Pulling from a CF is going to be a challenge without an overhead hoist to not bang anything up during the extraction or install. I use a Gantry Crane with about 14' under hook height. The gantry is about 18' in width so an engine is picked, slid over, then set on a pallet, cradle, or truck bed for the next operation(s). I suppose a forklift with a side shift mast would work also but I've never done it this way.
I assume you are pulling an EN-707 series engine. If going to a diesel there are a few to avoid in the application like just about any END-711 if staying with Mack. Assuming you want to stay with a Mack engine a good selection would be near any early 70's ENDT-675, ENDT-676, or most any E6 series of the early 80's. If you plan to incorporate air to air CAC, you have a lot more options for power upgrades. Regardless, step up the cooling capacity as you really need to get the heat out of the heads and a heavy multi row radiator core is the way to do it best. Airflow is somewhat impeded in that chassis design so could use help, (IMO).
thanks for the info!

repowering from gas to diesel...
-
I have seen engines for sale. it appears that they are resting on the oil pan. is it in illusion, or are the oil pans that thick that they can handle the weight without warping?
-
yeah I have researched gantry cranes, forklifts, even bobcats and I wanted to know if anyone ever tried a 3 ton engine hoist or would it not be able to lift high enough...

WHAT WOULD BE THE SAFEST WAY OF REMOVING AN ENGINE, PARTICULARLY FROM A MACK C OR CF MODEL FIRE TRUCK?

hey Paul that water tower in the background sure looks like it might say 'MACK' on it. did they have a plant in Syosset back in the day?
-
ok so you clarified one thing for this new guy but you added a wrinkle. what is this bridge formula that you speak of? AND MERRY CHRISTMAS BY THE WAY!

hey paul I saw some engines for sale. one is a 676 with tip turbine (I assume 285 hp) and another 676 with tip turbine (but 350 hp). is this tip turbine the forerunner to the charge air cooler but without the additional radiator?

THIS NEWBIE HONESTLY IS IN THE INFANT STAGES OF LEARNING! I SAW THE B MODEL REGISTRY SO I THOUGHT SINCE THE L CAME BEFORE THE B.....I AM SURE THERE MUST BE DOZENS OF L MODEL OWNERS THAT NO DOUBT COULD PUT THAT TOGETHER...
-
IS THERE AN L MODEL REGISTRY?
-
I saw awhile back where the doors on f and r models are the same? what about windshields? can you use windshield off of a cf or r model on an f model?

thanks

FIRST TIME SEEING TR671 TRANNY. WHERE ARE THE ID/MODEL NUMBERS STAMPED?
-
I was doing some research on mack engine specs and a torque chart came up on D&W Clutch and brake company. the chart shows a EM6-300L engine had 300 hp @1750 rpm and 1425 ft/lbs torque @1020 rpms and E6-350 engine had 350 hp @1800 rpms and 1277 ft/lbs torque @ 1250 rpms. a certain used parts company lists an EM6-350 for sale. did mack ever make an EM6-350?
-
is that mackinaw gray on those wheels?
-
hey 39 baby mack could you tell this new guy why the difference with spring brake on/off?
-
can you tell this greenhorn what ESI stands for?
-
at first glance both the mack 300 (285 hp) and 300 plus (315 hp) appear the same. what is the easiest way to tell the difference between the two (unless by cleaning off the engine tag and giving mack a holler).
Low air pressure on start up

Does it pay to rev the piss out of engine to build air pressure? I have a chart that lists various air compressors and they ALL are rated displacement @1250 rpm. We were all told at driving school that you can rev it all you like, it's not gonna build pressure any faster. Any thoughts?
