|LCAC_Man #1027 LBZ Duramax Conversion|
|Author: LCAC_Man (Show all albums)|
This album will cover the Duramax/Allison conversion(including dash cluster integration), installation of airbags to assist suspension, conversion of vacuum brakes to Hydroboost, replacement of Onan gas generator with a Onan/Cummins 5500LP, inverter/charger installation, dual roof a/c installation, and Bedroom reconfiguration that will add "pass-thru" storage.
Used 3/8"x4" flatbar to weld directly to the swing arm.
I had to remove the brake assy at the backing plate to get to the under/backside. Nodular iron welds up pretty easy, even in overhead position..
Couldn't resist, I mocked up the dash as it will look when finished.
I reused the small switch panel that previously was populated with now removed systems. EGT and Boost gauges just fit with all the interference that's behind them.
After kicking it around I decided to just go with all new switches and make everything match. Scan Gauge II lets me monitor stuff like Inlet air temp and a few other things that the cluster doesn't.
Having the tap shift and tow haul buttons close to the shifter and at a comfortable/easy to reach position was important. I can rest my hand on my knee and reach these easily.
New 3 gallon aluminum air tank, pre-plumbed as much as a I could. Tank purge valve, swivel hose connection, air horn valve and pressure sending unit all installed.
tank is installed on the backside of the passenger front wheel well, fits up in there nice and doesn't take away from the storage area.
Safe-T-Plus installed, these things really work well and give a much more positive "return to center" in the steering.
No chassis style mount available for the FMC...so I made one using the material from the mount that came with it when I got it off craigslist..
fabricated two heavy angle supports, these will bear the bulk of the weight of the house battery bank.
new house battery bank, 580ah, I used the original air conditioning belly pan and laminated it with 3/8" thick HDPE so it will carry the weight without bowing.
