Dan Markley drove his Sprinter system down from Missouri, an 18 hour drive, to have us reengineer his Genesis DXT. This unit and van are under two years old. I will take more pictures of the interior. The trim and shelving are outstanding.
With the unit installed it was virtually impossible for Dan to access the components; especially the pressure pump and the belts for the blower. You will see in my photos as I am converting the truckmount to an LP system, I am eliminating a tremendous amount of unnecessary parts. This removal of parts is opening up the unit tremendously for servicing the components.
Dan is going to let us simplify the system and eliminate all proprietary parts. We will be removing a lot of electrical parts. Dan was having a lot of reliability issues with the unit.
One other big issue was that when he would clean high flow under commercial carpet cleaning conditions, his temperature would drop below 170. We are going to add a #4 Little Giant heater which will give Dan a sustained 240 degrees on high flow.
His fuel consumption for this heater will be ½ gallon per hour. This additional fuel cost will be compensated for by reducing his engine rpm from 3,000 rpm to 2,000 rpm. Not only will the lower rpm cut fuel consumption by 1/3, but it will also increase the engine life by 30%. The unit will also be a lot quieter.
In this set of photos, we are removing the engine coolant heat exchanger. Notice as we are removing parts, it is opening the system up. Behind the engine coolant heat exchanger is the exhaust diverter.
This diverter system is a very innovative design. I really like it. It actually uses a vacuum ram to actuate the exhaust diverter with the vacuum of the truckmount. We removed the exhaust diverter and bypassed it completely.
The water box was blocking access to the pump. Also, the float system was electrical. You can see the electrical floats in the lid. These were wired into a relay which activated a solenoid valve for the incoming water. The water box relay and solenoid will all be removed and a mechanical float valve will be installed in his water supply tank.
As you can see in these photos, removing the water tank has really opened up the access to the pressure pump and blower belts.
The main exhaust heat exchanger was located under the bottom right of the unit. We removed it and the electrical switches that went along with it.
This electrical control panel will also be removed.
Powerclean made a very nice filter system for the blower.
The belt-driven pump out system will also be removed and a diaphragm system will be installed.
As you can see as we are removing parts we are really opening the system up for service accessibility.
One severe issue with this unit was that the pressure pump was unable to move forward or backwards to tighten the belts. As you can see in the photo, on the right side of the pump the chrome shaft cover is touching the vacuum inlet pipe to the blower, preventing the pump from moving forward.
Also notice the pulley of the pump is almost touching the machine frame, preventing the pump from being moved backwards. Dan would just have to keep buying new belts when they got loose, because there was no way to tighten them.
I will post update photos as we continue with this conversion.
