Freightrain Posted March 14, 2016 Author Share Posted March 14, 2016 Nothing. This supposedly came from a fire truck if that matters? The feed for air compressor is on bottom of water pump. No other holes like on my old motor. This having an oil cooler makes it slightly different set up. Just curious if anyone has an r model with 237 to see where they route the hoses.

thomastractorsvc Posted March 15, 2016 Share Posted March 15, 2016 I opened a photo bucket account as I can only up load to the galley and it says I am 135% over my allocation. Anyways, see if this works. As you can see from the picture it runs from the waterpump housing up to the heater and returns to the manifold near the temp sender probe.

Freightrain Posted March 15, 2016 Author Share Posted March 15, 2016 Hmmm, ok. Only problem is I have the 673 waterpump on it. I have the fitting on the bottom of it, that is where the line goes to the head of the air compressor. I do have a fitting in the top of the front manifold where I was going to hook one line(that motor just has a plug in it). Just not sure of the water flow and where I would need to bring it back in? I have the temp sender in the same location as that picture. I have the shutterstat in the same location also. Quote Larry 1959 B61 Liv'n Large......................

thomastractorsvc Posted March 15, 2016 Share Posted March 15, 2016 Maybe you need to change the water pump or could you put a t-fitting in? Quote Robert"I reject your reality and substitute my own."

Freightrain Posted March 15, 2016 Author Share Posted March 15, 2016 The original 237 had the line coming off the bottom of the pump, going around the passenger side to the air compressor(just like the 673). That I will reuse with my 673 pump. The one heater hose came off the front/top of the water manifold and returned back into below that area(mine had no oil cooler). I'd have to go look again to confirm. The 237 manifold does not have a fitting in the front since it has the water filter set up on it. Then the oil cooler does not have any fitting in the front either. I'll get some pics and post them, likely tomorrow night. Quote Larry 1959 B61 Liv'n Large......................

Popular Post 85snowdog Posted March 15, 2016 Popular Post Share Posted March 15, 2016 Here some pics Larry. They reinforce what Robert said. The water line for heater is off the left side of the water pump. The line for the compressor is off the right side at the bottom. You have to excuse the oil on everything. Truck has plowed for 31 years now, and its the oil that stops it from being a big pile of rust. 3 Quote Keith Link to comment https://www.bigmacktrucks.com/topic/42967-237-flywheel/page/4/#findComment-327548 Share on other sites More sharing options...
Freightrain Posted March 15, 2016 Author Share Posted March 15, 2016 Thanks Keith. I'll have to do some checking tomorrow and see where I can tie into the waterpump. I know I don't have room like that as the 673 pump is shorter and the pulley covers up most of the pump. Pretty sure mine came off the casting(where the oil cooler is at) but my 237 doesn't have a fitting there(just like yours doesn't). Where's Jim at?? Where did you tie your heater into on your 285?

j hancock Posted March 15, 2016 Share Posted March 15, 2016 Sorry, have the wrong answer for you. The B75 has a longer hood than the B61 so the 285 water pump could stay in place. Routing is pump to heater core back to the valve on the water manifold as pictured above. Heater? You only race during the summertime.... Quote JimIt doesn't cost anything to pay attention.

Popular Post Freightrain Posted March 16, 2016 Author Popular Post Share Posted March 16, 2016 Well I looked at my 673 pump, there is plug on the drivers side I can remove and put a nipple on for the heater hose. Looks like it will work out after all. Tragedy averted. Thanks guys. Mike, I'm thinking the Winfall Wimmin would probably get the truck nice and warm for me..........but thinking Karen might not be to keen to the idear. 3 Quote Larry 1959 B61 Liv'n Large......................

Mike Posted March 16, 2016 Share Posted March 16, 2016 Larry, the day I came up to see you, you were keeping her pretty quite. BTW, you have not introduced her to the BMT family yet.

thomastractorsvc Posted March 17, 2016 Share Posted March 17, 2016 have you thought about making the return < t > into the compressor?

Freightrain Posted March 17, 2016 Author Share Posted March 17, 2016 The original line came back into the casting the water pump bolts to(which is now the oil cooler-see the flat spot on top of the elbow going to cooler).

theakerstwo Posted March 17, 2016 Share Posted March 17, 2016 The water pump is were the heater needs to return to cause that is the suction side of the pump.Any thing on the block or manifold will be pressure to the heater. 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/42967-237-flywheel/page/4/#findComment-327709 Share on other sites More sharing options...
Freightrain Posted March 17, 2016 Author Share Posted March 17, 2016 Correct Glenn. It draws water(heat) from the water manifold, goes to heater, then returns to the water pump.
