Forgot to ask--- do you have a part #?

Thats even better than my idea. I was saying mount 4 filters because of the size of the two filters that are already mounted to the truck. Is one filter sufficient?

Ok, I need some input. I am trying to get rid of those two ugly oil filters that are in my first two pictures(one of those pictures should have been of a rusty old Luber Finer, not sure where it went) and just trying to clean up the exterior of my B. I am thinking about remote oil filter mounts, like on a race car. I have an area that I can hide them very nicely and they take spin on filters like a Baldwin B99 size. I can plumb them into my existing set up with no changes and ditch the two old filters. I can get either single filter mounts or a mount the has two filters. I am thinking 4 filters for my setup, either 4 mounts or 2 double mounts plumbed in series. Race car mounts seem to be the best option because the fittings are for a larger hoses. Help ? Comments? Advice? Thanks Bob

Hi Terry, I checked my motor and it is equipped with an oil cooler so I probably don't need the one you have, but I am still interested in the oil filter stand if you are interested in selling it separately. Looking at some of the pictures of the spin on set up, I don't see any of the 2 hoses that run to the oil cooler and the one line that runs to the turbo. Are they just hidden behind the filters? Thanks again for your help.

Ok ,here's what I got from this info. I need to look for a 2 or 3 spin on oil filter housing from a 625/237 Mack motor starting in about 1967, that was equiped with a turbo. Gasket are still available and its a straight forward bolt on swap. Terry asked if I had an oil cooler,not sure where to look or what they look like, if you guys could help me with that I would appreciate it. Also if any of you Mack guys have the correct oil filter housing I would prefer buying it off a Mack guy rather than searching for one. Truck salvage yards are few and far between here in Mass. Thanks to everybody for all your help!

Was the 675/237 a factory motor in some B models or are they transplants?

The motor in my B was swapped over to an ENDT 673(gold in color if that helps determine the vintage). The first picture shows the oil filter mounting plate that is mounted to the block with hoses going to a Luber Finer and a secondary oil filter that is in the second picture. (I have the cab off the frame and just needed a place to hang the filter, that' why it looks a little strange). My question is, I have a parts motor with the original style oil filter mounted directly to the block(third picture). That motor is a End 673. NO TURBO. Can I take the oil filter plate off the first motor and get rid of all the hoses and 2 crappy oil filters and just bolt on the original style oil filter with no oiling problems? Also if thats possible is the gasket to mount the original oil filter to the block still available? Thanks Bob

I am installing a used/rebuilt air compressor on my "B" with a 673. The compressor came of a running engine and already has oil circulated thru it {not self lubricating}. Do I need to add any more oil or will the engine oil fill it fast enough when I start the engine B4 there is any compressor damage? Thanks

When I drain my air tanks I am getting oil mixed in with the water/air. Its a fair amount and if I leave the petcocks open it will drip small amounts of oil for a day or so. I am thinking the air compressor is bad. Am I on the right track?

Was the air compressor with the pump mounted on it a common Mack part? If so what years should I be looking at and are the air compressors fairly standard to bolt up to a 673 engine? Thanks

The pump mounted on the air compressor might be the way I have to go. A few people have suggested mounting another pulley on the crank and mounting a belt driven pump up on the engine. Not sure, because I have not done a lot of investigation, but it looks like and extra pulley would push the balancer out to far and it would rub/hit the radiator. This is on a B61 and there is not a lot of room between the balancer and radiator to begin with.

Anybody out there have a GOOD B model generator that was equiped with power steering that is for sale? The PS pump mounts on the back of the generator. I would even buy just the correct armature if its a good one. Thanks

I have a 57B with factory power steering. The pump is mounted to the back of the generator. I took the pump off to send the generator out to be rebuilt. The pictures are not that great but I need the rubber isolator in the back of the pump. Any suggestions?? Thanks

Its been interesting but I think I have my problem figured out. Over the past few months I have posted questions about engine length,engine placement and trans mounts. I figured out my problem was gas engine tranny mounts on a diesel engine which pushed the the whole deal forward about 2 1\2 in. After putting the correct mounts on the tranny and pushing the whole combination back into the factory position I still couldnt get the tranny to sit in the correct position. After a few days off to clear my head I started with a fresh outlook. After much investigation,the pictures show what I found. My truck is a 57 B with the emergency brake drum on the driveshaft. The linkage for the e brake setup was sitting on the air tank, holding the trans up just enough so nothing would line up correctly. Moved the air tank back and everything fell into place and the leaning motor straightened up better. Thanks to everybody for all your help and I am sure there will be many more questions.

Yikes Matt, I was going to try and post pictures of my problem with my trans mounts but after seeing your trans pictures I am embarrassed to post any pictures. My truck sat deep in damp weeds and exposed to salt air for almost 5 years. I have the market cornered on rust. You do some really nice work. Congratulations.

Thanks for everybody's help. My tech skills are not that great but I will try and post a few pictures in the next day or two Thanks again

I got the frame/transmission mounts swapped from the diesel frame over to the gas motor frame. Everything seems to be in the correct position now for the diesel motor that is in the gas frame, but when I try to line up the holes in the trans mount to go thru the rubber mounts I need a pry bar to get one side lined up,but then the other side doesn't line up. The truck that originally had a gas motor in it{now converted to diesel}was a double frame truck. It looks like the double frame goes inside the original frame. The double frame is 1/8 thick x2 sides makes everything 1/4in narrower than a stock frame. Does anyone know if there are special trans mounts for a double frame to compensate for this 1/4in difference? I am thinking thats my alignment problem,I might have the wrong mounts. Thanks for the help.

Hey Matt,you seem pretty knowledgeable about these old Macks. Here's a few more questions. The engine in the truck I am trying to put back together is an Endt,the engine in my donor truck is a End. You mentioned in your first reply that the B67 had offset bellhousing bolts, but did they use the same endt/end engine series. just that it was tilted? Other than it not being correct do you see any problems with running the tilted engine in my b61? Lastly the replacement Endt engine in my b61 is painted gold{under all the grease} is that any indication of what year the motor might be? Thanks again

A few months ago I posted a question about my B that was converted from a gas motor to a 673. The diesel motor and trans seemed too long for the frame and the radiator support,radiator surround,and hood were modified longer to fit. My original question was,is the gas frame shorter than the diesel? After many months of measuring other B models I went out and bought a B parts truck that had a diesel. After many hours of trial and error I figured out that when the gas/diesel swap was made they used the trans mounts and frame mounts from the original gas motor.The diesel mounts,even though they look ALMOST the same, are different. After the swap, the motor and trans sit in the correct position. Here's my question,standing in front of the truck with the radiator out, the motor seems to lean to the left. Not a lot but noticible. Is this correct or should it sitting upright? Thanks

If you go to Facebook Marketplace Florida there is a guy with a B model that he is breaking up for parts that has a sleeper on it. Original??? It looks like one of the old narrow 36in sleepers.

Wow.Great info.One final question. You mentioned the lack of electronics. This truck is a wrecker with beacons,flashing lights and just cool old running lights. Its a toy,Christmas parades etc and will probably sit in the yard a lot of the time. Will the big elec draw from the added lights burn the generator fields more quickly? Thanks again for your help

Ok Here's what I am up against. The closest Mack dealer to me has changed hands and the people running the parts counter are on the younger side with limited experience, so when I explain what I am trying to accomplish it kinda confuses them. I have contacted 2 truck salvage yards in my area and they told me I could come up and "look around." Here's my question,is there a kit out there or somebody with the expertise that can take my generator and change the insides over to an alternator? That way my generator looks original and mounts in the stock location, and I can keep my PS pump mounted in the stock location on the back of the generator/alternator. Thanks

Somebody asked if I had found a solution to my PS situation. My donor truck{engine,trans} arrived yesterday. As soon as I get a chance to check out the compressor and see whats up, I will know which direction I am headed. Thanks to everyone who posted info and took the time to send diagrams and internet links.

If you could post a picture the 237 with the large pump on the back of the compressor that would really help me a lot. That way I know whar I an looking for.Right now there is a 673 in the truck, are most air compressors interchanagble? Thanks

Anybody converted a B61 over to a more practical power steering? Mine has the old style with the PS pump mounted on the back of the generator but its going to get changed to an updated alternator so I loose my pump. Thanks
