That three wheeler is from the era of no seat padding on the fuel tank. One of the greatest inventions was when they extended the seat forward.

Right at the FIRST anniversary of getting the CC on the road so I figured it was worth bringing the project thread up to date. Back in September, I redid the front brakes in their entirety. The truck had a nasty habit of ducking into oncoming traffic when I stepped on the middle pedal. My passengers tended to panic while I wrestled things back to equilibrium, so I figured I should address the issue.



Don't make fun of my Oreilly's parts selections. I have thrown enough good money at this beast; I'm entitled to take my life, and at most one other, into my hands when I mash the brake... if it saves me a few bucks. The scope of this project was to replace: rotors, calipers, hubs, and new hoses. After action: it tracks super straight when braking.



I've had the rear drums and park brake pads in hand for months but haven't brought myself to undertake that yet. That requires pulling the axles and I keep forgetting to order the socket I want to use so I don't have to do it with a drift punch. I should start an Amazon wishlist like all the intahoes and see if my fans shower me with gifts. lol.

Here's the PTO block off cover I purchased for my transmission. I took the occasion of changing the oil in the transmission to install it. The new oil level plug on this cover is at 8 full quart capacity, which is the 'overfilling' level commonly recommended for the G56 trans. The next hole down is for a trans-temp sensor which I'd be ticked to install but I need another CAN adapter for the Edge CTS and well, I just don't want it bad enough for the $ that doohickey costs.



When I pulled the PTO block-off plate I didn't have a bunch of gear teeth fall into the drain pan. I took that as a positive. I added back 2 gallons of Mobil Delvac Transmission 50 per the Cummins forum. It did help with gear rollover noise, I don't even notice that anymore, but it is a little tougher shifting than what was in there before. I don't live in a cold climate or I might be starting all over again! Another popular choice is Amsoil MTG. I may try that next time.



Overall project rating is still 10/10, would bang again. If I'm traveling by myself, screwing off a Saturday afternoon, or just wanting to convert a few $$ into noise and black smoke; I'm taking the CC. When I go to CS for meetings I drive it and park on the roof of the hotel garage. Sometimes, as a walk away, I look back and snap a pic... it's hard to believe I bought this as a cripple wasting away under a tree in Halletsville 2 years ago. It has given me all the satisfaction of adopting a stray pup; if that stray dog sucked your bank account dry and mauled you each time you pet it. It has not been easy, light, or cheap, but it has been fun and rewarding.



For 2025 - running boards. I found some to my liking but they will require some significant modification/fabrication for the finished look I have in mind. I'll update when done - I like how they're shaping up.

God Bless ya'll and your families this Christmas Season. I hope your time wrenching in the shop is rewarding.
She's pretty! Looks out of place with out a cattle trailer hooked up to it though!

Okay, 6 months into 2025 and this hasn't happened yet. That gives me 6 more months to live up to my promise.

However, I need some help from y'all. If anyone has a third gen with running boards, would you please crawl underneath and snap a pic of how/where they attach to the truck? I have done a lot of online research sorting through different running boards and their instruction sheets trying to find examples - but I'm finding very few that go back to the third gens. Like I said in December, I have the steps I want, and I have figured out how to fabricate a bracket to them... it's the truck attachment point I'd like to see examples of. I don't know if they drill through the pinch weld, use nutserts in the lower rocker, or what was done. I really don't want to go back to the frame - it is a real reach - a loooong way over there; I don't think that will work.

Here is what it looks like underneath. I am thinking some kind of vertical strap that conforms to this contour - and maybe bolts through the pinch weld? (then I would weld the step bracket to that) I'd just like to see how the commercial guys did it.



For your trouble here is a shot of my current victim. Moving up in displacement, 8.2L - no emissions, no diagnostic codes, no battery, no lights, no fear. But you'd better have eaten your Wheaties before you showed up for work back in its day.

Will avocado toast suffice?

Probably better than Wheaties- but I'm guessing in the late 30s most guys were getting farm fresh eggs and ham before they went out and starting flipping that flywheel. You're whole day would start with a crap-out if your tractor was uncooperative.

Now after my appeal - I stumbled on these instructions and this tracks with what I was thinking. Bolt to the rocker up high and then drill through the pinch weld for a second attaching point. Not big on the slotted stuff but I'm only building one - for me - so I won't have to have that.

Anyone have better suggestion??

That looks real similar to what I went through putting steps on my '05 Chevy. 4 years later and they're holding up fine.

I would bet money that truck has a train horn under it!

Haha. Well. I don't have any of those things, to include rock lights or brake rotor lights.

A long time ago I had a set of Nathan Air Chimes on a 359 Peterbilt - not from a chrome shop - they came straight off a locomotive. That got train horns out of my system. But these glass watermelon lights started showing up in my social media feeds. I let a buddy use my truck, he backed over a curb and tore my mud flaps and weights off - so when I replaced all that I threw a watermelon light on the order.
