Well my hunch was right…. Saw a buncha new Volvos recently … and sure enough ,,, I’ve already gotten used to the new cab changes futuristic designs just might take off … let’s see

It’s too bad we can’t pick our kids mates

I had a look.That trailer sure suits your truck.Best of luck with it.Keep us up to date with your progress... Paul

bmt crew stands for Big Mack Truck members, as you will find out with your Mack build this forum is like a pit crew which work as a team . not doubting the model as B61 , the concave cab associated with B67 , a design made to accommodate longer trailers still maintain tight turning radius

lol frankly I think both picks are bozos

Not sure what the parts would be worth.

Yes it show b61t and 4 other numbers I reached out to the mack historical museum and they sent my build sheet and information on it. Also what is bmt crew not sure what that is? The caps were missing before I purchased the truck but already replaced most of the fuel lines.

This shows the lower rad connection, through the oil cooler to the center of the waterpump. Yes, you need to vent the scroll to prevent air being trapped, but centrifugal pumps ALWAYS pump from center to outside. Where the outside is connected to the block (top, bottom or side) doesn't change the fact that it is on the pressure side of the pump.

Yes he still has the trailer but the landing gear is seized and I told him I would be interested if he still had it down the road after I get the truck back on the road. My profile picture shows the trailer better. But he used it to haul steal.

a simpler version; if you check the engine picture from wayne86 and his '55 B, the water pump has a 1/4copper line off the housing pic 1 then pic2 shows the other end of line going to the thermo housing. this 1/4 line was known as the cavitation line; top housing would hold air. modern technology this line no longer needed. water pump draws from lower radiator through engine back to thermo housing and top radiator. heater copper pipe on lower radiator(suction side) pulls coolant from heater core while other copper goes to heater .

dumb me. I just realized I posted this on Hicrop's thread.. He too is doing great Mechanic work as well. Obviously highly skilled..

isn't the pipe coming off the housing a 3/4 dia ?? while heater hose pipe nipple a 5/8 ? I found a picture of a tip turbine Mack on line(can't figure this posting yet) it has a 3/4 +- hose going to water pump housing ; fans blocks clear picture. one version of tip turbine engines had water coolant used to lower air temp another went to air then to front mounted intercooler in front of radiator. point is : my guess is pipe on WP housing was for a tip turbine engine. this would also put pipe on right side of pump.

This was the one.

I think you have that backwards, it draws through the oil cooler to the center of the pump, centrifugal pumps always pump from center to outside. The block is on the pressure side of the system. edit: hum the post I was replying to seams to have been deleted?

I could never figure out why James Hebe at Freightliner tried to bring American LaFrance back. Fire apparatus is a tough business.

This is funny. https://www.dailymail.co.uk/sport/nfl/article-15595373/donald-trump-jared-kushner-ivanka-tom-brady.html

totally different world in today's "mechanics" thinking. saw that when at coke , couple of flunkies did nothing/knew nothing. then there's the management with Ideas of::: let equipment stay out of service so I can increase my yearly budget for purchasing new junk ; have seen that attitude also.

237 was from late 60s firetruck supposedly. It had shutoff. This 300 came from late 70s R model and has shutoff. Factory? Or something someone put on? The water pump housing on 237 came from my 673. The housing on this motor was the original and has stand pipe instead of nipple down by the oil cooler. I actually installed a shut off valve from a 70s Ford truck and have a choke cable running up to dash so I can adjust heat while driving.

rear shutoff valves are installed since the b's didn't have best air conditioners back in the day. without the shut offs. coolant would still circulate in cab. is it possible reason for two different fittings in front were due to one had brass pipe return other rubber hose ??
