My Dusty 71 GMCe Electruck

[Gregski]

Captain's Log: March 2022 B.C. [Before Conversion]

commencing operation March Madness (aka a simple 4 step EV Conversion)

Step 1. Remove hood

... feel free to follow along at home, any car will do preferably your exes, ha ha

[Gregski]

Step 2. deICE

in this step we liberate any and all systems pertaining to the Internal Combustion Engine

here we removed the exastulators and weighed them for those on a strict diet

Note: we included the Ram Horn exhaust manifolds for a complete exhaust system

Total Weight: 71 el bee eses

[Gregski]

next we removed the Pavement Lubrication System aka SBC

Note: it broked the scale, which only goes up to 660 lbs

[Gregski]

this left an empty engine bay cavity, which I am telling myself repeatedly:

you will not strip
you will not clean
you will not paint

as this is an Electrification and not a Restoration

Wait! is that flippin' purple?

[Gregski]

we went after the fuel tankulator next, and for that we had to remove them buckets, which gots ta go to the upholsterererer anyways

I think that's a 16 gallon tank, any guesses how many Home Depot 5 gallon buckets it took to drain it?

We also weighed the tank: it came in at 35.0 lbsers dry as a bone

[Gregski]

so what is that? 71 + EE + 35 = 100 or so and since the scale craps out at 660 lbs we are talking about North of 7 fiddy

don't forget that The Greg drained all the fluids, and a 16 gallon fuel tank alone would add 16 x 6.3 = just over 100 pounds

since the new transmotor will obviously hold trans fluid just as the old one, we will call that a wash

same goes for water/coolant, the new components (Inverter, Charger, Converter) are liquid cooled so we will call that a wash as well

[Gregski]

Next it was time for a little Stare and Compare

190 hp on the left over 300 hp on the right (Lexus GS450h dual electric motor transmission) you're welcome!

[Gregski]

so on a bit of a tangent, remember that this is a '71 cab, but it came with a '72 driver door which I replaced with a proper '71 door, but it don't fit right

[for those not familiar with these trucks, GM likes to monkey around with things every 2 years or so, so in 1972 they redesigned the doors ever so slightly and changed the inside door panels from metal to plastic, and we can't have plastic on a truck]

well after driving it with literally a string holding it tide to my seatbelt, yes I know super safe, I finally decided to pull the fender off to get to them up and down door hinge bolts to try and adjust it

[Gregski]

have you ever accused a good friend of stealing?

yeah, me neither, but if I did it would go something like this:

about 2 years or so ago a really good friend of mine asked if I would help him take the engine out of his SUV, so I said sure of course

I usually carry some tools in my truck, so I bronged some of my tools, my favorite 30 year old Craftsman ratched, and lets just pick a random socket say a 9/16ths (you know the one you hardly ever use on your truck) and to speed up the process I used it that day at his place, he worked on one side of the engine bay I worked on the other

after we were done, right around the same time I drove this truck aka Dusty to my mamas house and asked her if I could park it there for a couple of days [pronounced: TWO YEARS circa 2019 B.C. ahem Before Covid]

well I haven't seen my ratchet and that 9/16ths socket since I HELPED HIM !!!

which brings us to YESTERDAY:

[Gregski]

and then it was nothing to it but to do it, whilst making a video of it

GMCe EV Conversion deICEing

[rickcdewitt]

These 450h trans are much more powerful than the bolt ev transaxle gm used in their conversions right?

You'll need a trans cooler for this?

I look forward to seeing how well it holds up with no ICE in a pickup

Does a one legged duck swim in a circle? ha ha, night and day

[Gregski]

so I couldn't sleep at night not knowing the exact precise weight of the old power plant so...

[Gregski]

mandatory stare and compare

black and blue

[Gregski]

so first we weighed just the chain for you Super Geeks, and yes the scale has some super duper eliminate the weight feature but it sure wasn't working as expected

[Gregski]

and did we just pay another $50 bucks to find out this thing weighs only 17 lbs over the maximum 660 lbs of the first scale (which by the way we can not return since the return deadline has passed - BONUS!)

[Gregski]

and here is what the new(ish) 2010 Lexus GS450h transmotor (as we are calling it cause it has two electric motors inside) weighs in at

[Gregski]

and here is what the old spinny thingie weighed

[Gregski]

and here's what the new Lexus GS450h unmodified (will need the rear U joint replaced for a GM style one) drive shaft weighs

[Gregski]

and a mandatory stare and compare

[Gregski]

and here is what the Inverter weighs (the inverter translated Direct Current from the battery pack to Alternating Current for the motors, these are AC motors inside that transmission)

think of the Inverter as a Carburetor / Distributor combo

[Gregski]

and then we took the ol' engine out for a baff

[Gregski]

and made her wear a shower cap
