Mean Green Posted August 4, 2023 Author Share Posted August 4, 2023 Here it is with the new housing I need to get 1 more elbow for the top front fitting Quote If your going to be a bear be a grizzly Link to comment https://www.bigmacktrucks.com/topic/73126-b-model-673-oil-filter-housing-swap/#findComment-536266 Share on other sites More sharing options...
mechohaulic Posted August 4, 2023 Share Posted August 4, 2023 If I may ask? what is the purpose of the shut off valve on lower side of oil filter?? easier access to drain the oil ??? can't clearly see in picture other side of shut off valve . the bottom 3/8 pipe plug drain wasn't the best for draining the canister.

Mean Green Posted August 4, 2023 Author Share Posted August 4, 2023 Yes that was there to drain the housing Quote If your going to be a bear be a grizzly Link to comment https://www.bigmacktrucks.com/topic/73126-b-model-673-oil-filter-housing-swap/#findComment-536274 Share on other sites More sharing options...
Mean Green Posted August 4, 2023 Author Share Posted August 4, 2023 I’m changing to a spin on filter because I always have to wait for the oil pressure to build when I start it seems like the housing is always dry when I removed it not much oil came out I’ll see if this helps . Also when I removed the plate off of the block I removed the spring and plunger the spring was stuck in the plug when I removed it a bunch of nuts fell out what I can tell somone used the wrong plug witch if the spring didn’t fit right and there would be no spring pressure so I remover the nuts and put in a spacer to put the spring slightly spaced into the plug Quote If your going to be a bear be a grizzly Link to comment https://www.bigmacktrucks.com/topic/73126-b-model-673-oil-filter-housing-swap/#findComment-536275 Share on other sites More sharing options...
Freightrain Posted August 6, 2023 Share Posted August 6, 2023 I swapped mine out years back, but I was lucky to find an R model with a 711 set up for a motor with NO oil cooler. Bolted right on. Hens teeth today. I had messed with my full flow so many times trying to get the check valve to hold oil in the case so it wouldn't take 30 seconds to get oil pressure. It would be okay for maybe 1-2 starts, then back to 30 seconds. Never seemed to hurt anything, but just didn't like it, like I'm sure you don't. 1 Quote Larry 1959 B61 Liv'n Large......................

Mean Green Posted August 7, 2023 Author Share Posted August 7, 2023 Your right Larry I was reading all your old posts about it and it’s so hard to find the older parts mine was just like yours a good 25 seconds to get oil pressure I didn’t like that I let it sit a day and had oil pressure in a few seconds the housing has I bypass built in so it will divert around the filter if it’s plugged or reall cold oil so I figured I’m safe with that . I’ll paint it all up to match the engine paint that yellow filter gray and it will be good as new 1 Quote If your going to be a bear be a grizzly Link to comment https://www.bigmacktrucks.com/topic/73126-b-model-673-oil-filter-housing-swap/#findComment-536410 Share on other sites More sharing options...
doubleclutchinweasel Posted August 7, 2023 Share Posted August 7, 2023 Yeah, the old Oil Clarifiers tended to have issues with the check valves that would cause them to drain when not running. They were great when they worked...having the full flow and the bypass circuits in one unit. Looking forward to seeing yours finished.

Mean Green Posted August 7, 2023 Author Share Posted August 7, 2023 Well it’s all finished just have to put some paint on it takes up less space lol Quote If your going to be a bear be a grizzly Link to comment https://www.bigmacktrucks.com/topic/73126-b-model-673-oil-filter-housing-swap/#findComment-536484 Share on other sites More sharing options...
mowerman Posted August 7, 2023 Share Posted August 7, 2023 Hell, that’s ingenius I don’t have any trouble with my oil pressure but yes, it is a messy SOB to change the filter 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73126-b-model-673-oil-filter-housing-swap/#findComment-536486 Share on other sites More sharing options...

I would try to loosen and turn top hose toward engine front: might straighten lower hose.

mechohaulic Posted August 7, 2023 Share Posted August 7, 2023 not being critical - wouldn't want hose to split and suck in dirty air . filter change over is mint. nice job. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/73126-b-model-673-oil-filter-housing-swap/#findComment-536493 Share on other sites More sharing options...
Mean Green Posted August 7, 2023 Author Share Posted August 7, 2023 Thanks mechohaulic I’m happy with it I’m just glad it has oil pressure when I start it . That hose is like that cause the pipe is round but the intake manifold port is some what oval so it distorts the rubber and it’s 2 different sizes so there is a step in the rubber there . It has the crimped together manifold not tahr cast one cause I added the turbo 1 1 Quote If your going to be a bear be a grizzly Link to comment https://www.bigmacktrucks.com/topic/73126-b-model-673-oil-filter-housing-swap/#findComment-536499 Share on other sites More sharing options...
Mean Green Posted August 7, 2023 Author Share Posted August 7, 2023 I know it’s not original but finding original parts is getting tough so I figure if I can put new parts that are available and they work I try it out my next project is trying to find a freight liner fld or super liner axle with budd or hub pilot wheels to put under the front but I haven had much luck and what I have found is a little out of my price range for something I take to car shows 1 Quote If your going to be a bear be a grizzly Link to comment https://www.bigmacktrucks.com/topic/73126-b-model-673-oil-filter-housing-swap/#findComment-536502 Share on other sites More sharing options...
doubleclutchinweasel Posted August 7, 2023 Share Posted August 7, 2023 Did you plumb in both the Tull flow and the bypass lines?

Mean Green Posted August 8, 2023 Author Share Posted August 8, 2023 DCW no I didnt I just have pump supply in and clean oil out my original by pass way the tiny line to dump back to pan this filter housing has a spring and plunger in it so if the filter plugs or oil is cold it will go around filter and still supply engine with oil I figure dirty oil is better than no oil Quote If your going to be a bear be a grizzly Link to comment https://www.bigmacktrucks.com/topic/73126-b-model-673-oil-filter-housing-swap/#findComment-536531 Share on other sites More sharing options...
