terry Posted October 1, 2015 Share Posted October 1, 2015 I have heard rumor a 237 or 300 will suck the oil out of the oil bath turbo air cleaner on a B. might be worth changing to a paper filter rather than having the engine take off on you.Drove a 237 with a oil bath cleaner for years, never a problem ever. terry 1 Quote Link to comment https://www.bigmacktrucks.com/topic/41877-300-in-a-b-model/page/3/#findComment-305741 Share on other sites More sharing options...
Gmerrill0516 Posted October 2, 2015 Share Posted October 2, 2015 That air cleaner thing made my heart skip a beat. I'm trading back to the oil bath with the E6-250 turbo setup I have...Like the stock look. Thinking about it though, the volume of the ouside of the cleaner where the air is headed up into the intake is massive and I can't imagine moving enough air through it to suck up a steady supply of oil and making it run away...I suppose it could be possible....I wonder what the air velocity is inside that unit...???HMMMmmmm....? I guess I need to so some math. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/41877-300-in-a-b-model/page/3/#findComment-305867 Share on other sites More sharing options...
Dirtymilkman Posted October 2, 2015 Share Posted October 2, 2015 When I was in college for diesel we started out rebuilding engines on stands. One of my buddies poured a quart of oil in the air cleaner of a 300 Mack that was on a stand. We.watched the tach bouncing around 3200 till we finally got brave enough to snuff out the motor.

68-f-model Posted October 2, 2015 Share Posted October 2, 2015 If it was an issue why did my f-model come factory with an oil bath and a turbo 237? Either way my oil bath defiantly not getting put back on.

Freightrain Posted October 2, 2015 Author Share Posted October 2, 2015 Barry has an paper air cleaner that resembles the oil bath. I will just look into getting one(or something similar).http://www.wattstruckcenter.com/store/index.php?route=product/product&path=59_72&product_id=397 1 Quote Larry 1959 B61 Liv'n Large......................

39 Baby Mack Posted October 2, 2015 Share Posted October 2, 2015 Could shove this combo in there. 300 and a 6 speedhttp://www.ebay.com/itm/MACK-300-Maxidyne-Diesel-Engine-COMPLETE-TURNS-FREE-w-6SPD-TRANS-R690-/321856666274?hash=item4af026faa2&vxp=mtrThat's not a 300, it's a 237Ron 1 Quote Link to comment https://www.bigmacktrucks.com/topic/41877-300-in-a-b-model/page/3/#findComment-305928 Share on other sites More sharing options...
AZB755V8 Posted October 2, 2015 Share Posted October 2, 2015 That's a smokin deal on on that 300 & 6 speed. Put it in and GO. Pull clutch and air filter would be the big issues. Bet you could get the front mount and not have to swap engine parts. Think it has a wetline pump as well that's worth $ too.Definitely go with the paper. Don't take a chance with the oil bath. Those oil filter went by the wayside with the increased HP for a reason....

Freightrain Posted October 3, 2015 Author Share Posted October 3, 2015 Well the numbers say T675. Only downfall is intake and intercooler is missing along with oil cooler. Very clean motor. Supposed to be from 4500 mile firetruck. Clean gold paint and Maxidyne on the valve cover tag. For basically nothing I have in it i think I can piece it together into something..Just have to decide if I should worry about oil cooler and intercooler or just put plain intake on it? It has similar twin spin on that I put on my 673. I could just transfer over mine because it has broken chunk out of one filter mount plate. 1 Quote Larry 1959 B61 Liv'n Large......................

leversole Posted October 3, 2015 Share Posted October 3, 2015 Did the 675T HAVE an intercooler? I have the same motor (even mine is gold!), dont see any mounts or provisions for a intercooler?!?

Freightrain Posted October 3, 2015 Author Share Posted October 3, 2015 I guess I need water manifold actually that attaches to head and comes around for pump? It is all gone. I suppose I will need my water pump to make it fit a B? Damper is gone but will use mine also.How about intake? Tubing to turbo? Not sure what it looks like. Leslie can you post some pics of yours?

Freightrain Posted October 4, 2015 Author Share Posted October 4, 2015 Thanks Leslie. That helps a ton. Now I know what is missing.Is yours a drivers side starter? This one came with passenger side bell housing.I didn't know yours was a 300 or is it a 237? How's it drive with your transmission? Quad or triplex?

theakerstwo Posted October 4, 2015 Share Posted October 4, 2015 That is what I have in a B model but I install a air/air cooler on the front and run the air tubes thru the head light panels under the head lights.It sure made a big difference.Mine would heat the coolant until I had a custom rad made for it.One thing that helps when they are heating is to take the fender panels off of the top of the fenders.

Maddog13407 Posted October 4, 2015 Share Posted October 4, 2015 no intercooler or air to air is a 237.... I think a new waterpump is around 50 bucks larry. I know you need your 673 crank hub as its shorter. the 237 one is for a 3 groove pulley and theres not enough room between the dampner and the radiator crossmember. that water rail and oil cooler and filter setup is pretty commom also, but like we all know, non exhistent when your lookin for it. my cousin is runnin the smaller B61 radiator(the one that doesn't go all the way to the bottom of the horsecollar) with a 237 and it doesn't run hot. if your rad is in good condition you shouldn't have a problem. 2 Quote Link to comment https://www.bigmacktrucks.com/topic/41877-300-in-a-b-model/page/3/#findComment-306109 Share on other sites More sharing options...
theakerstwo Posted October 4, 2015 Share Posted October 4, 2015 Yes I forgot to say I had the maxidyne governor set to a theromdyne setting for a 320 and then I maxed the fuel out on it.

Freightrain Posted October 4, 2015 Author Share Posted October 4, 2015 I will look to get pump set for 250 at least.I'm thinking I might get the motor out right after my last race next week then I can get the flywheel and clutch out for this motor. I'd like to get things ready so I can run it before I put it in. I think I will pull trans also just so I can clean it up too. 1 Quote Larry 1959 B61 Liv'n Large......................

theakerstwo Posted October 4, 2015 Share Posted October 4, 2015 When you get the engine out the trans is easy to clean were it is in the frame if you have a power washer.To pull the front off of the truck leave the fenders attached to the rad and frame with grille in place.I have years ago pulled the engine and have it sitting on the ground before the engine has cooled off on a B model.Trans stays in the frame. 1 Quote glenn akers Link to comment https://www.bigmacktrucks.com/topic/41877-300-in-a-b-model/page/3/#findComment-306133 Share on other sites More sharing options...
