WORKHORSE CUSTOM CHASSIS SERVICE BULLETIN - 60701-T

[John-D]

Well, I got a good motor home that only required a few mods to make it into what *I* wanted (Adding ham and cb radios, some electrical upgrades, As for the engine, I won't say I have not touched it (I've added a quart of oil twice and changed it twice) but that is all.

Thouse who say "I bought one that does not need modifications" need to watch the TV show 'Home improvement. Those shelling out thousands of dollars for engine upgrades need to STOP watching it

Seriously, there are a lot of "Tim Taylors" in the world, If you pulled that 435 HP Vortec out and dropped in a 1,000 HP replacement. They would STILL be wanting to upgrade.

And if you are one of them, and are willing to take the risk and spend the money... Well, this statement is quite literal "More power to you"

And more money to Mike and Banks and the others in the "Upgrade Industry" And perhaps more money to Joe's Truck Repair when he dropps in a brand new 1,000 HP engine to replace the one you blew up should that happen (odds are it won't)

I took a look at the list No No's in this bulletin and here is how I looked!
The following are considered aftermarket installations that can cause engine or emission system damage:
"¢ Any change in PCM, TCM or ECM calibrations.
This one is obvious - UltraPower


"¢ Any change or modifications to the engines exhaust system.
Banks, Gibson and WCC SSC Option
UltraPower Aero mufflers
Technically I just did this. I cut the exhaust pipe off and added Chrome Exhaust Extensions.


"¢ Any change or modification to the air cleaner or intake system.
My DIY CAI qualifies here


"¢ Driveline modifications such as changing the rear axle ratio.
How about some bigger tires, it changes the rear end gear ratio slightly.

"¢ Installation of emissions components that alter original calibrations.
UltarPower and/or CAI
Taylor Plug Wires
Re-gapped Colder A/C plugs
