Fine thread bolt(5/16" I believe), fender washer and a foot pry bar is what I use.

Nice to see the AC engine gone, but that sounds like a big job. I'd start with measuring firewall punch outs....rest is trial (by fire) and error. I don't know anyone who dabbled out of Tier III beyond disabling.

Turbo and manifold in good condition. Take-off from 2005 AI460. Can have both, or just turbo for $400 + shipping. New Turbo price from Mack is $2,318.43. 2 years in service.

The fruits of our labor has been a very stable, calm, non-metallic, idle. When you work up the RPM's on the unloaded engine it is still very E-Tech, but as nice and silky as a PLN at idle. It doesn't disrupt the water tension line on my glass.

I had a Mack 6X6 DMM that overheated like that despite replacing all the usual suspects. I took the radiator to the repair shop to have it checked for congestion. They popped the tanks and attempted to rod out the core. The core had a soild center in the exact shape of the fan. It was a circle of scale occupying a round portion of the core. New core and problem fixed.

Well its good to see you back. I was starting to think we were getting censored by some greeney . What year truck was the exhaust manifold from and what model.
Nelm, could you please give me all information on the Tuner your running on your AI460? Any before and after interpretations?

Did you buy it?

I'm getting ready to adjust the valves on my 07 ac350 and the manual say I need a special torque screw driver for the spring loaded exhaust valves. What is the torque for this so I don't have to buy a special 1 use only screwdriver? Is this the same on all e7 engines? I already have the motor turning tool.
Apply pressure to collapse the push tube spring and set drag according to what you would have historically. The tool is a dumby-proofer option. I leave the wrench on the adjuster nut and tip my elbow onto the wrench it while I set the clearance. Need very little pressure to neutralize spring pressure.

Less embellishing going on with this one.....

Did Grand Rock assign part numbers that others could use to put the 5 inch on other AI applications? And what does CCRS stand for?
I contacted my Mack Dealership two days ago and they took the baton on following up with Joshua Stewart@ Rock. No word back yet on production cost or availability.
This is a single stack, Granite, exhaust system. I did not request anything relating to a dual Granite exhaust or other Mack vocational chassis (LE/MR/Etc.). I see no reason you could not make that request, they seem willing to take custom requests?
See attached for CCRS..

how much you sell them for? i am interested.
If you want the files get your e-mail to me and I will send them. Office Depot will make a 2'X3' for $20 on good paper. Perfect resolution. Amazon has cheap, but pretty good, poster frames for $12.

I couldn't sell them, I got the files from Dan for free. Unfortunately they are too big to upload. About 3X too big.

I got hold of Dan Roettger, from the Twin Cities. He made the early 90's mack poster series. Dan offered his high res files of the posters so I could make some 2' X 3' posters as gifts. They are too big to post. I have some smaller files.
Had a very interesting dialogue about the series.

In case you don't have an OEM ream Otis makes a brush for cleaning M4 and M16 that fits the injector shadow well.
I did bend the bristles as far forward as possible to try to get some shoulder strike, otherwise they do nothing to clean the fire ring receiver. You can't get the ramrod into #6 hole, so you have to cut it or punt.

Ahhhh, sweet nostalgia..... I still remember my first 237 experience. In the Impala, Mom and Dad both chain smoking, behind a DM with it's warranty tamperproof screws missing from the puff limiter.

The average "chump" which in reality is most of us,will never be deliberately given the whole truth by the hierarchy that runs the free world! I have no inside knowledge and never will ! But common sense says that China has the most people available to sacrifice in a a military confrontation, and we keep feeding them the profits from our former manufacturing jobs! They are only our ally because they need our manufacturing, what if they cut a deal with Iran or N.Korea or one of the many rogue states that hates us money tends to "trump" most religious and ideological differences, no pun intended! We need to watch our a..! Of course if I know that our security agencies know it too and a thousand times more!
Can't pick a fight with China...when we go to beat our plow shares into swords we'll realize we sold all our metal to China for cheap tricycles.

After the fact... we appealed to have a pyrometer port as standard to the new custom part description. The picture in the Grand Rock book didn't show a 4" with pyro port. I had my parts guy at the dealership interpret that dimension off stock parts and get back to Joshua. From my conversation it will be top radius center of first bend south out of turbo. I asked Joshua for an exact dimension stack muffler with 5" in and 5" out to be included in quote. No straight pipes in our neighborhood.
As of 6-23-2017 I have not received a quote for the custom parts. Doing follow-up Email first week of July.
I will need to know exact location dimensions if you want a pyrometer port installed.Grand Rock CompanyJoshua Stewart | Tech Support | Warranty | Returns395 Fountain Ave. Painesville, OH, 44077Ph: 440.639.2000 Ext: 115| Fax: 440.639.2010TF: 1-800-321-3674 -
Fifth, get yourself a 5" exhaust system. I called Grand Rock and asked if they would build a 5" exhaust out of the jigs used to make the replacement 4" exhaust. Many calls later and negotiating through my Mack Dealership.........
Good morning Jason,I did hear back from our engineering department.It is feasible for Grand Rock to build all 5” versions of the pipes you requested.There will need to be weld seams in both of the pipes you’re requesting, and have a GR level 4 difficulty.This means a minimum of 2 week production time will be needed once the order is placed.These are NOT stocked items, and will be Made To Order.Please advise your local Grand Rock dealer of this, as there will need to be custom part numbers created.If you have any further questions, please feel free to contact us.Have a great day, and thank you for choosing Grand Rock for your exhaust solution needs.Grand Rock CompanyJoshua Stewart | Tech Support | Warranty | Returns395 Fountain Ave. Painesville, OH, 44077 -

This is a great post! Only thing that would make it better is Dyno numbers. I've never dyno'd my 460
Thanks, I wish we had solid numbers too. Opinions are soft evidence. We have one truck dyno down in Wausau at the Cummins dealership, but generally very thin pickings around here.
Correction, made some calls, only one dyno left in Edgar, WI. $375 for the run-in. Doubt I could get the boss to pay that money to test a well-running truck.

Fourth, get a set of over-size injectors. I used K & S fuel injection of Wausau, WI. They have a reputation for doing well on Mack stuff and keep cores so you can swap out at the counter for your new Injectors. No turning them in and wait. Mike requires the Mack part number of the OEM injector for the specific truck, then he refits the tips accordingly.
I told my buddy, before buying any specific truck, that we would play a bunch with AI427, but not as much with AI460. I feel increasingly bold about pushing more torque into the crank of this underpowered 460. The 1999 E-Tech 460XT was actually building 487 horsepower, but listing as 460. The block can take it.....460XT was putting out 1,760 Ftlbs of torque at 1,200 RPM. The stock AI460 is putting out 1,250 Ftlbs at 1,200 RPM.
Mike puts the injector life span at 5,000 hours before they lose performance. He says the CCRS is tough on injectors. Double hits per injection cycle. $85 per injector including soft parts kit, pretty affordable performance.
The injectors will add smoke on the take off, but clean up/spool up fast. I attached a video.

Mike did try to do some housing swapping to check feasibility of swapping larger housings onto AI Turbo. It was a fail.

Drain coolant, water fill with chemical flush, run easy for 1/2 hour with cab and sleeper hvac on "hot", drain fast and hard, water fill, run easy for 15 minutes, drain, fill with water, run 15 minutes, drain, install new coolant filter, add 2 gallons straight concentrated extended life coolant with SCA, top off with 50/50 coolant. Cummins use to make a really good flush. We used it to remove motor oil from cooling systems after oil cooler cluster failures.
