nam vet Posted November 22, 2023 Share Posted November 22, 2023 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?

mattb73lt Posted November 22, 2023 Share Posted November 22, 2023 My concern with that last photo would be flow volume through it to supply the block/turbo. Additionally, getting replacement filters for that unit. It might be worth it to scrounge around and find a triple filter arrangement off an ENDT-675 with the spin-on filters. It would make servicing the engine a lot easier. This is the arrangement on my 675(237) that’s in my B42. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73571-oil-filter-relocation/#findComment-542330 Share on other sites More sharing options...
JoeH Posted November 22, 2023 Share Posted November 22, 2023 There's a few different arrangements for these. Id agree with Matt, scrounge around for a filter bracket from an endt-675/6. They at least come in 2 or 3 filter setups, it boils down to an option the truck was originally ordered with: ESI or ESI+ (extended service interval) the ESI oil pan was a mid size, with 2 oil filters. The ESI+ was the 3 filters with a huge oil pan, something around 56 quarts, 14 gallons. The bigger the pan/filter arrangement the more miles you could get per oil change. Not sure if there was a single filter option, all mine are 2 or 3 filter setups. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73571-oil-filter-relocation/#findComment-542331 Share on other sites More sharing options...
JoeH Posted November 22, 2023 Share Posted November 22, 2023 There will be a port on the top of the oil filter stand to tap in for your dash oil pressure gauge.

Freightrain Posted November 22, 2023 Share Posted November 22, 2023 There are a couple variations to that block plate and likely gaskets to match. I swapped my original 673 NA to spin on and had to get correct mount for "non turbo" motor. A turbo version should be easier to find. I used my motor manual book and reference what my block looked like once I removed the full flow plate like you have. My 673 did not have oil cooler and that is another option.

mattb73lt Posted November 23, 2023 Share Posted November 23, 2023 237's are transplants. I did some research into converting my END-673 to spin-ons, but had to replace it before that with the 237. It was pretty straight forward with the filter housing bolting directly to the oil filter pad. Port alignment was not an issue and there are several gaskets available to line it up. I was looking to do it because the filter elements were getting harder to find. Another plus is that there are no external oil lines to route or worry about. Filters can also be had that are shorter in length to get you around clearance issues.

nam vet Posted November 23, 2023 Author Share Posted November 23, 2023 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.

mowerman Posted November 23, 2023 Share Posted November 23, 2023 I got my oil filter from Amazon now I’m waiting on oil lines getting rebuilt good luck to you I would have preferred to change to spin on like you want if they were easier to find and at my age this will probably be last oil change good luck bud… bob Quote Link to comment https://www.bigmacktrucks.com/topic/73571-oil-filter-relocation/#findComment-542366 Share on other sites More sharing options...
mattb73lt Posted November 23, 2023 Share Posted November 23, 2023 If you have an oil cooler, it'll sit just below the left side of your intake manifold and to the left of the oil filter pad. It'll be round, about 3-4" in diameter. It should have two large flex lines running into it and back to the filter pad. If you look at my photo of the spin-ons you'll see it.

Doesn't your spin on system have two metal oil tubes on top of filter housing one to each end of oil cooler? terry Edited November 23, 2023 by terry Quote Link to comment https://www.bigmacktrucks.com/topic/73571-oil-filter-relocation/#findComment-542381 Share on other sites More sharing options...

nam vet Posted November 26, 2023 Author Share Posted November 26, 2023 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. Quote Link to comment https://www.bigmacktrucks.com/topic/73571-oil-filter-relocation/#findComment-542504 Share on other sites More sharing options...
terry Posted November 26, 2023 Share Posted November 26, 2023 I think the stand I have you have to use the oil cooler with it, it has two hard lines with o rings between cooler and stand, I’ll have to dig it out and take a look.

nam vet Posted December 1, 2023 Author Share Posted December 1, 2023 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 Quote Link to comment https://www.bigmacktrucks.com/topic/73571-oil-filter-relocation/#findComment-542751 Share on other sites More sharing options...
JoeH Posted December 1, 2023 Share Posted December 1, 2023 I'd plumb them in parallel, not in series. In series, the first filter catches everything and clogs, leaving your other filters clean and useless. In parallel, the oil can go through either set of filters, so you're actually getting the use out of having that many filters. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73571-oil-filter-relocation/#findComment-542756 Share on other sites More sharing options...

nam vet Posted December 2, 2023 Author Share Posted December 2, 2023 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?

Mean Green Posted December 3, 2023 Share Posted December 3, 2023 This should be the same one and at a good price I know cat wants over 600 for it the filter holds about a gallon and was used on 15 liter engines one thing to check on them is where it says bypass remove the plug and check for the spring and plunger if it’s not in there oil don’t get filtered Quote If your going to be a bear be a grizzly Link to comment https://www.bigmacktrucks.com/topic/73571-oil-filter-relocation/#findComment-542826 Share on other sites More sharing options...

mattb73lt Posted December 3, 2023 Share Posted December 3, 2023 You can easily do a single spin on. I did this to my NH220 in my B73 from a canister filter to a spin on filter.
