I have a 99 pete with a 3406E cat. It started missing bad today and I tok it by the pete shop in Little rock they said they think it was the injector o rings or a fuel line leaking. I changed the fuel filters to just take that out of the equation. But still missing. Its only when it gets hot and at full pull. Can anyone give any advice on what to have them check before it turns into a 5000 dollar exploration. thanks.

This is what my truck is doing and not one can find the problem. so did you find what was wrong.

Help I am at the end of my chain. I have a Cat 3406B in a ford LTL 9000 which is pumping coolant out of the overflow after about 1 hour of driving. I have put a new head on it, changed the aftercooler, had the air compressor check but the compressor has blown a few head gaskets in the past year, had the Radiator cleaned changed the cap. When the head was off they changed one liner and checked the hieghts. I have put a new water pump on it.It done the same thing this time last year and then went away when it got cooler weather. I only thing i have done different is turned the heater taps off but they are telling me that makes no difference. It has cost me thousands and it is still not fixed.

I have a 2000 Kenworth with CAT 380 C12 motor. In my normal check of the radiator I found greenish/black sludge in the reservoir. Can someone tell me what could cause of this?

Gday fellow cat powered truckers My question is How do you change the front engine seal on a 3406b Do you need to remove the timing cover or can the job be done without removing it thank you

The front seal can be replaced WITHOUT removing the timing cover. You will need to remove, in this order...
Fan blade, fan clutch, harmonic balancer. On some trucks the radiator shroud bolts are removed so the fan blade can slide between the radiator & shroud. I use a medium screwdriver to "break-up" the rubber center-ring of the seal, which allows me to "pry" the outer metal ring out easily. There will be a metal "wear-ring" still attached to the crankshaft. Use a two or three jaw puller, the arms need to be narrow.
Pressing the seal in place requires a special tool. If you don't have one, you could possibly rent one? When re-assembling, torque the crankshaft/harmonic balancer bolts to 60 ft lbs, then 120 ft lbs. The fan clutch mounting bolts torque to 80 ft lbs. Good luck!

What causes high pyrometer/exhaust temperature on 1992 3406B Cat engine (fully manuel)? Have already had the charge air cooler tested and changed the boots on the air lines to the charge air cooler. Any ideas?
