Engine/Transmission (1998.5 - 2002) Spinner II install

[Mundgyver]

Thought someone might be interested. Routed the 1 inch drain line into the rear turbo/dipstick port on the passengers side. Oo.

What is it for? I'm not familiar with the Spinner.

 

[Mundgyver]

Is is a centrafuge bypass filter. The main purpose is to actively remove the soot build up in the oil which is a wear component. It will filter down to . 5 micron particles. This will allow me to extend my oil changes out to 20,000 with a goal of going to 50,000 between oil changes. Oil monitoring through oil analysis will be required.

It is a by-pass oil filter. Mack has used the same type of by-pass unit for many years. Mack calls it the Centrimax.



Oil pressure causes the "filter" to spin, throwing the soot and whatever else towards the wall of the "filter".

How is that return line plumbed into the block? Is it an actual threaded fitting, or just something you pushed in there?



And that braided hose is beautiful... where'd you get it!?

The port is the second port in the block Cummins casts in for a turbo oil drain. Second gens use the front one, third gens use the rear. It's just a steel tube with an o-ring push in a hole with interferance fit.



The braided stainless is standard issue at most hydraulic supply shops. They can usually press on NPT or JIC fittings at any length for you. Less expensive than you might think too

Mundgyver,



Is the spinner 2 messy to empty? How often do you empty the unit out? I am presently running a Amsoil Dual bypass on my 4. 5 and was curious if this could also be added? Could there be a problem with Oil pressure to run a unit like Spinner 2 and another bypass setup? Looks like a nice unit to remove more of the soot. The amsoil bypass does keep the oil clean but you can still see very dark oil. I was hoping this may keep the oil that much cleaner. What do you run for oil. Can you read the dipstick thru the oil? Mine is very hard to see thru the oil and I would like in kept cleaner.

Thanks, Jeff

I love questions The braided return line does in fact go to the rear oil return port on the passengers side of the engine. It's fabrication though was done using the standard turbo drain fitting that Cummins makes for the port and a Stainless Steel 1inch ID pipe thread to barb fitting. I cut the barb fitting off and then trimmed the turbo return fitting. Next we ground out the stainless fitting where the barb use to be for a nice tight slide fit over the turbo fitting which by the way comes with an o-ring. This was zipped together with my welder into a nice custom 1 inch oil return line. The braided line both on the return and the supply are teflon coated inside and rated to 400 degrees F. I had both line custom fabed at A-1 Coupling in Tualitin, Oregon for about $84. The mount for the spinner was made out of 3/8 chanel iron welded to the top of the alternator mount. I then welded a 1 inch threaded pipe to the bottom after creating the holes for the drain port and bolt pattern. The unit will operate between 25 and 90 psi and will not activate untill it sees 20 psi. MY idle pressure is 30 psi and my cruise pressure down the high way is 60 psi. After 20 hours of run time on Amsoil with 8,000 miles on it I extracted about a tea spoon of what looks like black wet coal cake. The oil texture before felt like thick pancake syrup and now it feel thinner and cleaner. I have two sample out for analsys at Blackstone labs waiting for the results. The mail man is very slow at delivery. My goal is to go 50,000 to 60,000 miles between oil changes. I will still change out my filter and add make up oil every 7,500 miles. I know of delivery trucks up in Canada that are doing 125,000+ miles between oil changes. Servicing requires that I just open it up and wipe it out and put it back together. I have an oil sample port that I pull a sample while the engine is running also. I use to run the dual bypass set up. I run this one now. It is not messy with care. Just take a few rags and a good wipe. My oil color is getting lighter the longer I run.

Mundgyver,



I don't believe I fully understand your oil drain set-up. I, also, have an '03 that I would like to install a bypass system on.



I was thinking about tapping into the turbo housing drain that goes into the block. It looks like a 1/2" pipe.



Do you think the 1/2" pipe will handle the extra flow of the bypass system? I think that is what you have done but, I did not see where the turbo drains back into the block. How did you address that problem?



Thanks for going to all the trouble to show us what you did.

Buffalo,



Our trucks are just like his down on the block. There are 2 turbo return ports - one of them is being used by the turbo and the other one has a plug in it. To use the other one you just remove the plug and insert your custom fitting.



Mundgyver,



Do you happen to have the Cummins part number for that turbo drain fitting?



-Ryan

Thanks, RBattelle.

Here is what you are looking for. This is the turbo block return fitting for our engines. You have 4 ports to pick from, 2 on each side of the engine. The part number that is stamped into the side of this is 3931973 USA. I got this from Cummins Northwest. I bought 2 of them just incase I screwed thing up. The remove these from engines all the time to reconfigure for what ever applications they have. The cose me $2. 50 each as they are consider used. :You will notice that they come with an -0-ring also. What I did was cut this in half right about 3/8th of an inch above the block stop flare. I then inserted this into my stainless steel 1 inch pipe thread to barb fitting and welded it around the flair. This way I did not have to share a port with the turbo. Much easier install this way. My braded hose is a 1 inch inside diameter swaged to a 1 inch female that will screw onto the drain fitting I created. Hope this helps.

What method did you use to remove the plug?

You just got to love a seal puller

Jeff,

Are you taking periodic oil analysis using the Amsoil by-pass? My latest analysis in Jan 2005, was showing 0. 50 ppm SOOT with 31,500 miles on the oil. I am now ready for another analysis, so I will see how it is running as far as SOOT is concerned.

Mundgyver,



Excellent thread. Many thanks!

Glad you all like it. When I do my next inspecton / clean on the spinner, I will provide pictures of the material that is removed and what it looks like dirty and apart.

Thread Fitting

Do you think the wall thickness of the fitting could be threaded to accept the oil return line?

 

[Mundgyver]

It would be thin I think. Thats why I used a stainless steel 1 inch male pipe thread to barb fitting adapter. I cut the adapter barbe off and welded the two pieces together. It made a very nice tapered fitting inside for the transition point. I think what I will do this Wed. when I have my first day off is go get one of the adapter fitting and take a picture of it and then make another fitting and take picture of the process of assembly. That might be more helpfull for everyone to visualize and then you could see vice trying to visualize in the mind.
