Since you are trying to get your CDL and everything you do is being supervised try and shift around 1500+-50 rpm 1450-1550 rpm. You will eventually be able to shift without touching the clutch( except when starting out).Get the double clutching down, get the CDL and then move ahead. Remember if you try and shift with the rpm too high it is not going to come out of gear for you.It goes into gear best as the rpm is falling so you will have to run it up some.If you can't get it into gear run the rpm up again and try again. Make a note of when it went in and notice the enjine sound too. Hope this helps!

Lubricant and time are the friend of amateur truck mechanic. I don't see any lubricant on that frozen nut. Lube it up or get out the checkbook!

I am by no means a mechanic, but you have failed to mention the differences in transmissions and gear ratios. Gear ratios in the rear ends and the horsepower ratings of each respective engine. I am just trying to help you find a less costly solution to your problem.You may find changing the rears or transmission may allow you to work in a more comfortable environment and allow you to reduce your fuel costs.

Those dayton wheels and hubcaps just set the whole thing off!

Check the coolant level in both the upper reservoir and lower. One of the sensors may become exposed and trigger the lightning bolt. The bolt itself means electronic malfunction.

Have them look and find the "front door" to the Sangamo tachograph as shown in picture#3

My 864 is long gone and I never met it.

In case you guys dont know the hood is made of Aluminum. So are the headlight panels. I have stripped mine and polished them. If you do strip yours you will need to polish them to keep them in top shape

Hey Superdog that means mine is 25 trucks older than yours!

Hey leversole we have seen pictures of all inner workings of your 615. Where are the pictures of the outside in daylight?

Mine is a little older than yours. My # is B615T1044. I am guessing you are a tandem axle too.

The cab is made out of Maxiglass . It is a composite material made by Mack. It is fiberglass with powdered aluminum mixed in and cast.It will not rust and was very light and tough too!

UPS ran the hell out of the MH tractors.When they were new the trucks were running about 22 hours per day, and they did that for years. They slip seated them and they ran ALL the time.

I like your idea better!

It is on the passenger side frame under the fender well

THE ADJUSTMENT YOU SEEK TO DO MAY BE FIXABLE FROM UNDER THE TRUCK AND NOT THE FLOOR PLAN DOWN.I TRY NEVER TO MESS WITH SOMETHING Unless Iam ready to redo the entire thing. Remember these are old trucks and parts may be brittle and ready to break. You might as well go to walmart and buy a case of spray lubricant. I have fooled with so many frozen bolts and nuts the I give up immediately and grab the lubricant.

One of mine is gone and the other tank has an insulator that looks more like a canvas strip.

I cracked mine too.I still have enough to hang it back on though.I thought about using some fiberglass repair substance to wrap around the cracked stuff

Run the rpm up. remember it goes into gear as the rpm drops. how much weight is on the rear frame does it have a fifth wheel, I have been driving big trucks for 17 years. When I get into my 615 its a different world. you arent goin to get this down by watching videos or down in a couple of days either.dont force it either unless you have unlimited funds. it just goes to show you the quality of drivers in days gone by.

I got passed by a tanker last summer. He had the cap off the passenger side fuel tank. The fuel nozzle with about two feet of hose was sticking out of the open tank.Do you ever watch the news and see some bad truck wrecks? The public doesnt appreciate a safe well paid truck driver until a disaster hits their own family. These guys who drive and get paid the same as Mcdonalds employees arent doing anyone a favor.

Take her picture in the daylight! (and post) I know you are out in the yard right now!

In lexington Ky the last of the MH model were painted over the brown UPS paint with a roller loaded up and when I asked where they were bound for it was South America or Africa. Pretty much the same story for the first of the retired CH models too.I heard they went for a few thousand and when I inquired if we as employees could buy one the answer was no. They were all sold to one buyer. Those Mh were tough as hell. I saw an enjine blow one night and it still kept trying to run with a hole in the side of the block. UPS had to make a fortune off them. I cant believe they went out and bought another make of truck over the Mack! They had to roll the miles back in the computers that monitored PMI stuff as it would not take the actual miles on those units. All the parts books are gone too. I fear that they probably lined the dumpster with them

I drive a ch for UPS and my tractor did the same thing. Let me know if you are still having this problem and I'll ask my mechanic what to do.

Mine has a filter canister in it and the oil is in the bottom of it. My air cleaner is off as Iam stripping it to paint it.If you take it off the truck dont tip it over because the oil will run out.Also be carefel with the piece that The hose goes onto. It feels like fiberglass to me and I cracked it!

Thank you. I will try that!
