These aren't your grandpa’s gaskets.

A blown gasket can be anything from a minor annoyance to leaving you stranded on the side of the road. You don’t have to put up with whatever gasket you can get your hands on; our gaskets are engineered to withstand anything you throw at it and last well into another million miles. No doubt about it, these are some of the best gaskets on the market.

It's no secret that diesel engine parts can cost an arm and a leg. That’s where HHP steps in. We offer premium aftermarket gaskets at up to 50% off OEM prices. While most believe aftermarket retailers sell cheap gaskets with zero warranty, packed in a dusty box from who knows where, HHP is here to kick that stereotype to the curb. HHP provides gaskets fabricated for unstoppable performanceand a 2-year warranty. How’s that for an aftermarket part?

How to timing Injection pump and preparation for installation for 3406B CAT ENGINE
AgTalk Home


I have an old classic 1985 peterbilt with the 425 3406b in it. Having lots of trouble with soot on startup and even revving while engine is warm. Also, not a whole lot of power...as compared to what legend has it for this model. I really dont wanna run much higher than 70-75 just want the power to pull the hills with out having to downshift a whole lot. Ive got the old 15 speed with 455's in the rear. I asked a mechanic last week to turn the fuel down a little to see if it would help my economy at all...and ended up with same amount of soot and dropping from 5.3 mpg to 4.8. I heard i can get up to 6.5mpg if set right. I know its simple to open up the air/fuel mechanism on the back of the pump...just need to know steps to adjust it properly. Also any other hints or tips would be great. Ive checked turbo and clamps throughout air cooler system. Also had diphram in the injection pump checked. I am leaking a little oil right at the throttle lever on the side of pump and right at the cylanoid.

soot is normal they load up on fuel then not clean burn fuel mileages on them is 5-5.5 what is boost pressure. should be 25psi two swens on back with nuts in deep to hold in place,allen wrenth screws,should be even with eachother

turbo pressure guage maxes out around 15...sometimes a little higher...sometimes a little lower. replaced old turbo a year ago with used...not new but in decent shape. sound like an air cooler leak? fuel pump adj wouldnt affect turbo pressure huh?

Iowa

That truck/engine probably needs more items checked out, and inspected, and rebuilt, and adjusted correctly, than you may have considered. I like the engine, but things wear out, too.{so won't be as simple as adjusting the air/fuel ratio control valve}

A. Need to pressurize the Air to Air Aftercooler (ATAAC Core), The side weld may be cracked and leaking lots of boost/air volume

B. Timing Advance unit probably needs rebuilt and adjusted properly, then set pin-timing about 1 - 1 1/4 degrees advanced. Need to verify operation/adjustment of timing advance unit with a CAT Dynamic Timing Indicator tool, also.[with these numbers, then graph it out, then readjust towards the upper max line on CAT's timing graph THRU-OUT the rpm range)

NOTE: Timing is the 2nd most important item for fuel economy. Driver is #1.

C. AFRC needs to be pressurized to insure its diaphragm/ internal shaft o-ring/ and rear gasket holds boost pressure. Next, it needs to be adjusted correctly (either by dial indicator or by the "smoke on acceleration" after it has been "cocked")

D. Nozzles need to be tested; good chance they leak fuel at the upper body o-ring and/or bleed screw. (do a valve adjustment, while you are in the 'topend")

E. The plungers and barrels of the fuel injection pump are probably "clam-shelled" = uneven mating surfaces, where they have to hold in high pressure fuel. They probably need "lapped" and/or replaced or update the top bonnets and bushings to the newer style=uses different sealing area to mate to the "barrel". 

F. Probably have the fuel pump set 2 - 2 1/2 full turns out, on each screw, from factory settings [This is were an old customer of ours ran for years, and got good fuel economy  (6.2-6.4 mpg) Seattle to Las Vegas run. He keep everything up and adjusted very precisely]

Your throttle shaft oil leak probably needs the updated bushing install= reamed out the alum housing(special tooling), then squarely install new bushing and new lip seal.

Well, I have probably spent 6000-8000 dollars by now.(or more)

Timing Advance units are often overlooked, by Non-CAT Dealer mechanics. Years ago, this was the trend we saw.

 



SW IowaI'd do what CatGuy suggests, just about in that order. Don't swap injectors unless the old ones are junk. A good set of used ones makes better power then a new set. We've seen it on the dyno, and a list of pissed off customers that their truck is down on power after an injector change.

Correct me if I'm wrong Catguy, if the AFRC diaphram is torn, it will cause low power. Will it be extra smokey too? I can't remember now.

Michael

Wow...thanks, I'll do it. Thats a lot but I appreciate the help. Ive owned and driven this truck for four years...just been fixin everything up by urgency and importance. Finally getting to the point to tackle this kinda stuff. If im able to get up to the 6 mpg range will i still have strong power and acceleration? economy is more important but just want to know. Can ATAAC be welded if cracked? Throttle shaft leak of any relativity to low power or mpg?

Iowa

On his year, 1985, it should be the "boost-cocked" style of AFRC, so if the diaphragm is torn/ripped, then it will have lots of black smoke, during acceleration; and will NOT limit hp at all(it NEVER gets "cocked" to limit fuel/rack travel)

Around 1991, the serial number prefix "3ZJ" engines, had "oil-cocked" AFRC, then with oil pressure , they limit fuel until boost pushes on the diaphragm(assuming a good diaphragm), but if the diaphragm is blown/torn/ripped, then it DOES limit hp severely(if adjusted correctly, and not super "rich" AFRC setting)

Now, the newer "oil-cocked" AFRC do fit older engines/governors, so anything is possible, depending on what is on his engine.



Iowa

ATAAC cores, We use AV-TEC(after-market), if available for that truck model. We have had good luck, but one of my ex-coworkers in Omaha, said they(CAT dealer) went back to buying OEM ATAAC cores and had better luck with those for reliability.

The guy, I mentioned from Seattle to Las Vegas, tried lower fuel settings= more shifting and little less MPG. He immediately went back to higher fuel settings. NOTE: That was the only thing he changed, for that one trip.

Also, he drove it nice and smooth, but 65-70 mph. Just not a hotrod driver. (no shoes allowed in his cab, he only wore socks in his cab. Towels covered the whole floor)

Did I say very precise and picky, earlier?(about this driver/owner)

Your throttle shaft oil leak is just an oil leak, as long as your throttle linkage goes to "full throttle" and gets "breakover" at that pivot area, it will have no effect on power.

Another item, I just thought about, is that the flyweight races(inside the governor) probably are getting so worn, that you probably aren't receiving full HP at the very upper RPM range. Say 1900-2150 rpm, but you really shouldn't be running constantly in those rpms anyways.(all depends on when fuel governor was rebuilt last????)

 



I'll get the ATAAC checked tomorrow...their pulling the radiator off anyway to fix some oil leaks on the front asessorie drive housing. 65-70 works for me...i average 65-68 right now when all is smooth sailing. Its just been a frustraition with low economy and not a whole lotta pull like on the 40 through nm-az-ca. I'm not a hot-rodder either...i cant afford to break anything.

SW IowaWhile they are working on the accessory drive, have them rebuild the timing advance too, or at least have them check it to see if its working properly. Its been a long time ago, but when I was in the 3406 class I can remember the instructor showing us how the timing advance not setup right can really effect performance....
