Etu

Followed Joey Mack instructions on bleeding and it worked fine.

Gotcha. Thanks so much.

This is my line set up. I’m assuming you are polishing the tip that goes into the injection nozzle holder?

Thank you so much Joey Mack I understand about the Emory cloth on the seat. But how do you torque condition the nuts going in the head?

We just replaced exhaust gaskets and of course had to remove the injection lines. Now we are having difficulty bleeding the injection lines. I can’t seem to find the procedure in my copy of SB-210-034. While searching on line, I also read somewhere these lines are one time use?? Is that why we’re having trouble bleeding? Any feedback appreciated. Thanks

That is robbery. I just used the PAI 831016 Exhaust Stud kit that contained the 12 studs, 12 copper locking nuts and 6 gaskets. It was $113.75 usd. hopefully you can find another source.

I just replaced exhaust gasket on my 2001 350 hp ETech. The original studs were threaded full length which means you have to be very careful on the lower ones to prevent hitting the push rods. I replaced with an updated stud which is threaded only as deep as required to give the 1.75” length outside the head and avoid setting too deep in the head. It’s very easy to get the 20ftlb torque while setting these updated studs. The oil on your lower stud comes from oil in that section of the head where the push rod operates. The stud you removed by hand apparently did not have the required Loctite 272.

Thanks Jojo. Where would I look for that service bulletin.. on this site? Or through Mack? thanks for the lead. I found a listing of Mack SB and I believe the one I'm looking for is SB635008 but I can't seem to access a copy.

Thanks V, after cleaning ive got much better air fłów but i cannot get The modę box to divert air to the defrost or floor. Right nów it seems to be stuck on a mix of face vents and floor. Mine has the electric switch to select mode and I'm not sure where to go from here. (Is it the switch or the mode box?) If it's the mode box how do you get to it?

Ok I pulled the air duct on the right side and the core was very dirty. Vacuumed it clean and also pulled the fan on left side. Used compressed air to blow through core from the fan side. When I pulled the fan there was a blue filter between the fan and the coil. Not sure what benefit of a filter on the clean side of the core. Also think the air doors are not diverting air correctly. Going to check that out before I reassemble.

Thanks. I'll report back what I find after I do what you advised.

Is there's any benefit to pull the fan to access that side of the evaporator coil?

Thank you. I'll do that.

I have a “new to me” 2001 CH613 with little to no air flow from the ac vents. I cannot find any info on replacing cabin air filter or cleaning the evaporator coil. I’ve removed the cowl around the console and can see the fan but don’t know where to look next. Any advice will be greatly appreciated. Thanks

Wow. Thanks this is very helpful. Much appreciated.
