My last post is if you have Mack rears... sorry I forgot to add that...

Well all I can say is.... replace the fronts with 24's, put 30/30 maxis on the rear.. As far as auto slack adjusters go, on the rears you may have a hard time finding ones that will mount to the s-cam. I tried to do this to 2/ 86 RW's, and I couldnt find a parts guy that new how to cross the Mack numbers. the left and right are different. and the s-cam on the left side was too short ( by about 1/4") to allow a modern ambidextrous slack adjuster to be secured with the snap ring at the slack adjuster.. this being said,,, I am not 'all knowing' there may be a good auto slack out there that works. We just put the manual slacks back on and maintain proper adjustment,,,, just like in the olden days.. and with that being said... you can adjust your brakes to perform the way you need them too, and be safe and legal... I welcome all opinions and corrections about my posting... jojo

I did say I use PAI oil pump's... I did notice after 2 engines that the oil pressure was 5+ PSI lower at a hot idle then I prefer.. They had 28-32 PSI.. I have seen 35+ with Mack pump's.. However, overall the oil pressure is good... Just a side note... and these engines got new cams and bushings.. It was after the second one that I developed this opinion.. Don't fear it, just know it..... Jojo

how many trucks do it? are there other hired trucks that are doing the same thing? Is it just because you are on sand? empty or loaded, or either? jojo

I hope it makes air better than it looks... at least if you have to replace the compressor, you will have the plumbing done...

I would say.... Just keep doing what you do Paul.. even with air dryers water still collects, and guys just expect them to work forever, and they don't... Even with a dryer, when you pull the tank vent cables, water still comes out,. Not a whole lot but some.. just my 2 cents... Jojo

Great news about the lines.. I have built 1, E-7, and 2 E-Techs, and 2 ASET's. An AI and An AC... All are running good and making money.. I measured the liners and the pistons and compared them to Mack parts and they were the same. The PAI kits come with more parts than a Mack kit, including head gaskets.. the bags of gaskets and o-rings is great.. it even comes with the little sealing balls for the piston cooling tubes, and depending on the level of the kit you buy, you may have new cooling tubes as well.. I also use their oil pumps, and cam kits. Cam kits are better than Macks current kit.. the bushing set for an E-Tech was just over $100.00... you will need to order connecting rod bolts separately.. I have had great service from the PAI parts... At half the cost or less... Jojo

The line is in the center port. That is a D-2 gov. He should be able to plumb it right using the posted diagrams.. jojo

Yes sir.. I almost mentioned the compressor mounted gov. But thought I should see what is asked next.. you the man!!! Jojo

I don't know if I would know what a spammer looks like..

You make me laugh Mech.. do you think the diagram I posted is good enough info? Is it missing something? Jojo

It's really sad that he cant remember that his son died of brain cancer and not in combat in Iraq... OMG....

you can also use the WEB and go to the dryer website for what Mech Is saying.. the info is out there ..

Paulie,,, did you see the B+W diagram I posted? It really is that easy... jojo

OK Mech. this last pic is for you...

the 1/2" connectors was probably a by-pass, due to an issue... just look at the diagram I posted and follow it... it easy after you stand back and look at it.. jojo

gov. is controlled by 1/4 lines...

ok,, im done stealing this thread... jojo

here are some more...

Onyx,,, is that the one with the bolt through the bottom that holds the filter in place? or is it the small one with the screw on filter?

A ground not hooked up???

AD-9 is the best... big,,, but the best.... IMO..

I only have around 100 books, but its easier to go to the web while im in my jammie's, then go out to my shop and flip pages.... You'll know when I'm posting from my REAL book's... jojo

heres my secret....... go to the web... and type in,, Basic air dryer and governor diagram..... I answer so many questions by doing this... I copy and Paste, and Vwalla... jojo
