Rear gearcase mounted CP3

[HoleshotHolset]

I'm looking at an '01 vintage ISB 170 (3. 9L) for a conversion project that has a rear mounted gearcase with the CP3 mounted low. It was mounted in an '04 FedEx type truck with a 1000-Series Allison and now it is for sale since the truck crashed.



Installation issues aside (due to the having the gearcase in the back... )... has anyone seen premature failure of the CP3 due to water/snow/road jerky hitting it when it is all warmed up? I'm not sure of the tolerances in those things but they have to be tight to make high pressure like that. I've always read that you don't want to splash cold water on a hot injection pump... so I assumed the same held true with high pressure fuel pumps...



Here's a picture of the bad boy in question... I think (hope) that is power steering fluid all over the place in the picture.



Thanks,



Matt (12-valve fanatic possibly about to expand his horizons to... drumroll please... drumroll!... COMMON RAIL INJECTION!)

you wont have to worry about the cp3 getting harmed by the normal effects of daily driving,the cp3 in general has a high life expecancy on our trucks. 03-current are better than they ever have been. !! good luck :-laf

Well, mine was just replaced at 19000 miles on a stock truck. Go over to DTR, and search for "CP3", and you will have an evening's worth of reading. They are NOT reliable, IMO.

My 03 has 250K on the original CP3 and inj. . Lift pump quit at 198,500 and I drove it 1377 mi. with 0 fuel pressure, it quit on me at 199,877, and is still running fine. Lift pump was replaced with an OEM from Cummins. Started out at 20K with a box from Quad, and has had some kind of box on it every since. Its an early 03, took del. in Dec. of 02. Still has original brake pads also.

I think I've seen 2 ISB high pressure pumps done in the past 8 months at work, they are for the most part rock solid, the only leaks I have heard of have been ram's, and I haven't seen ANY at work yet. Keep in mind they are used in fedex, ups, all kinds of bread van type trucks, F-650s, etc etc etc

Looks like a great buy to me, Matt. How much are they asking for it?

They use that design a lot Matt. When I toures the B series assembly plant in June 04 they were building two engines, the one for our Dodges and one for the they called an ISB-02 for the Ford, Freightliner, Monoco, etc market. The ISB-02 had the rear mounted cp3 design but IIRC it was up higher with a large air compressor below it.

Thanks for the input, dudes.



They're asking $5. 5k for the combo. Yeah, that's a lot of money for a guy like me to be spending... but it's a complete package. All the wiring and ECM's for the engine and transmission are included (the guy said that they took the gauges out of the truck too... ). To me, it seems like it is worth it for a setup that should just plug-n-play. I've seen new ISBe 3. 9L engines going for over $5k and used ones without trannies or wiring going for $3. 5k...



If this works out, it'll be one heck of a daily driver. Details on that to follow in time...



Thanks,



Matt

I thought you guys would have a lot more to say about this... (On edit: If any of you would like to talk me out of it... or make statements why I should move to the 21st century with common-rail injection - let me hear 'em! )



I'm getting close to placing an order - speak now or forever hold your peace!

What kind of liftpump fuel filter set up does it use?

 

[rbattelle]

If I had the cash, I'd buy it. Can't wait to see what it ends up in!

I have no idea. I'll probably end up using one of those evil FASS things...

Well, there's one 'thumbs up'. I hope to take all kinds of pictures in the near future of the project vehicle in question. Until I know I can make all of this happen, I don't want to talk it up and then end up scrapping the whole idea. It won't be revolutionary, but it sure will make for a comfy daily driver.

I'd stick it in a '90-'95 Defender 90.



Of course, I assume you'll clean it up properly first.



Have you considered the fact that the oil pan is "backward" from normal passenger vehicles? I mean the deep part is at the front rather than the back. This could create problems if you want to put it in a 4x4...

I can't afford a D90 - they are sweet, though.



The oil pan issue is all-set - check it out:

Here is a link to another thread I've been posting on. There are more photos and such.



Here's the info I found (copied from the other thread):

I just called Cummins and found out that the oil pan on that ISBe (170hp, 3. 9L) can be flipped end-for-end for front or rear sump (SWEET! ).



Here are some part numbers I managed to get...

Cummins part # (as of 2/8/06):

4897997 OEM oil pan

4896964 oil pickup tube for REAR sump

4898301 oil pickup tube gasket

4897887 oil pan gasket

I'm going to look at a 105hp mechanical 4BT today... doesn't hurt to check it out, eh?



Matt

 

[rbattelle]

How do you find this stuff!? I wish I had access to places that carried engines like this (or small single-cylinder air-cooled diesels for snowblowers!).



-Ryan

 

[HoleshotHolset]

It's easy - I'm obsessed and possessed.



Matt

 

[HoleshotHolset]

I went and looked at that mechanical injection 4BT, it was in good shape... but not 'great' shape. Spray bombing an engine with paint may hide some flaws... but not all of them.



Here's some eye candy...

I placed an order and wired the money for the aforementioned ISBe/Allison combo. Oo.
