6/7 car high mount Cottrell Miller Sun Valley Wally Mo

Most transmissions have oil coolers on them, on our tow trucks we had larger coolers on the transmissions since we would run the pto for hours on large accidents, our tractors are set up the same way and I have not noticed a rise in transmission temp during the summer months. I will leave my pump on while loading or unloading our Miller trailers without trouble and we have yet to replace a pto or pump, one is 14 years old and the other was 12 years old when we sold the tractor. we do use synthetic gear oil in the tranny and synthetic oil in the hydraulic system with a large tank (30 gallons) so that may help. The only hydraulic system we had any trouble with was on our Landoll 7 car carrier, the fluid would get very hot, we installed a hydraulic cooler with a 12v fan and still had trouble then we found some restrictions in the feed line at the nose of the trailer, fixed that and all was good to leave the pump on to load (took about 45-60 minutes depending on how damaged the cars were), don't know about the tranny temp on that unit the tractor didn't have a temp gauge.

 

Just these 2:



This trailer got stolen from me.
I had problem clearing tandems on a extremely tight turn, but it was rarely an issue.
I think it gave me more than feet of extra room at bumper level.
I am in market to buy new trailer right now and leaning towards a Wally-Mo 7 car custom.

 

I have a miller t7 no shotgun deck but the top deck extends and raises to load a headrack on the truck. I had this trailer behind a Volvo with the meritor freedomline 12 speed tranny with no clutch. Volvo wanted an unreal amount of money for a PTO setup for this truck because it has to be tied in to the computer somehow since there is no clutch to engage the PTO. So I mounted a 10 gallon hyd tank on the truck with a push pull diverter valve from northern tool and run the trailer off of my power steering pump. pull the lever the pump works the trailer push it back in and you have power steering. I run 100% transmission fluid though and no hydraulic fluid since it is going through the powersteering pump. hydraulic fluid will cause the pump to fail early.


Several people warned me not to do this, said it was too hard on the power steering pump. but in three years I have replace one pump and it was the stock one and was a little weak when I done this conversion. I would not recommend this on a 5309 Cottrell or a trailer with a lot of cylinders but the miller has only 6 and 2 of those just extend the back ramp and the fron top ramp to load the head rack. really ony 4 lifting cylinders and I can lift 3/4 ton and one ton trucks no problem.

a new powersteering pump is $230 and only 2 bolts and a 10 min change if it does go out versus the over $3000 Volvo wanted just for the PTO and computer link, not installed.

 

I will add one note on axles, in the past we had Ingersoll Rand axles 17.5, always had brake issues, switched to Hendricks and they have been much better.

But on the last two trailers I had built 2011, 2012 we went with Ridewells and were probably one of the first Air Disc Brake setups they built, I would hate to buy anything else at this time.

No adjustment, no fade, no heat build up, very good build quality, excellent stopping capability's and feel, the only issues we had were both axles had seals that leaked within a couple of months, replaced them with the one piece Gold series seals and have not had an issue since.

I need a trailer like right NOW! But I may buy a cheap/old trailer just to get me buy, I hate to spend big money for a trailer and have to settle for something that is a compromise.

 

Yeah, I hear ya, the funny part is I was looking at some of these prices and remember a deal back in 08/09 I could have bought all of those trailers, used them for the last 5 years, and sold them for what I would have paid for them, (palm to forehead)!

I think I am just going to get a decent wedge or S/A SC 5 car for the new guy, and see where it shakes out.

 

I think they are loading those side rails or something with gold on the high mounts from looking at the prices. lol
I will say they don't depreciate like a stinger trailer does.

 

At this point I am half thinking of buying a stinger and having a "neck" put on it!
