I can see them and they look good from what I see. No tears in the rubber that I can visually see. If I jack up tranny they move over an 1.5” is that normal?

They look square

Oh duh sorry 2013 Mack mru

Have a question about the tranny mounts that bolt to frame. They have the rubber buffer inside them. I have an odd sound coming from tranny sounds like a pickup with worn out ball joints creeking inside truck. Only when driving. I jacked up tranny and both mounts move up with it. I assume there suppose to move some. Is there a way to know for sure they have to much play in them? This just started about a week after a new clutch and remack tranny was installed. Thanks in advance for any help!!

Thanks Geoff, that is some useful information. I’ll get to work on the leaks.

I understand what you’re saying and appreciate the help. I drain tanks daily and I am getting a decent amount of oil and water out of the wet tank. Is that from compressor cycling to much? Is there a concern about how much water and oil it putting out daily to worry about mechanical failure of compressor? What I’m saying it’s going to take some to pin point leaks in the mean time im worried about losing compressor

Ok is the reason leaks? Which would make it cycle more often

Ok, no it’s popping off every 3-4 mins. So I need to look for leaks to main tank and governor?

Ok I called Mack and got a breakdown and that’s all they use is silicone heater hose. But a new one broke apart after a months use. I see a little oil coming out of air tank. So I guess it’s time to change compressor. Could the compressor be cresting back pressure if it’s leaking oil? I just want to make sure I don’t have another problem before changing compressor.

Ah ok thanks a lot !!

There’s a one inch off that runs off side of air compressor feeding drivers side air intake. Is this for extra boost? The hose broke a week later after replacement?

Ok thanks for the advice

Well I think I found the problem brittle wires and coating coming off in wiring harness right where it bends over air compressor. The harness is a complete engine harness. 1800. Anyone replaced one before? Just wondering if I should try to do it I called Mack they charge 12 hrs for it at 195.00/hr

I got cover pulled I do not see any damaged wires or looses plugs. What would be the next thing to check

Ok thanks, this is my first mp8 I have had all e7 past 20 years. The blowby tube that comes out of cover. Does that twist out or take the cover off with it
