T474 & 394 Cab roof removal pics

cohocarl · Oct 9, 2021

I was looking over my 474 for the best way to mount & run the wiring for a reverse camera & monitor and took a few pics after seeing how easy it was to remove (or tilt up) the cab roof.
All that is holding down the top of the cab roof are 5 bolts. One on each front corner, one on each side, and one on the rear in the center. I removed all of the bolts with the exception of one side bolt that I loosened up enough to let the roof tilt up from the opposite side, but will help keep the roof from sliding off. I tilted up the opposite side of the roof and propped it up on the back corner with a Tupperware like plastic container. This gave enough access to all the goodies up there. (The nuts are captive/built into the roof)
**The roof could easily slide off if bumped too hard, but with only lifting it up about 6" and the loosened bolt on the opposite side acting like a hinge, I didn't have any issues. (There isn't much extra slack for the antenna cable to lift it up much more than that without removing it from the radio)
While I had mine propped up, I saw how easy it would be to swap out the Kenwood stereo and put in a Pioneer unit I had from a vehicle that I removed it from a couple years ago. (much easier to read display and I was familiar with it's operation.) I was lucky to find out the wiring harness for the Kenwood and Pioneer have the same standard plug into the radio so the swap was very simple. Hardest part was threading the two side screws on the R side of the radio, but it's do-able.
While I had the radio harness off, I soldered on a fused lead to the 12V switched wire which I ran down the front right cab pillar to power a reverse camera & monitor (more pics to follow on that install)
After I had the stuff done on the left side, I removed the container I used to prop the roof up, lowered the roof, put one bolt back in a few turns, went over to the R side, removed that bolt and propped up that side to fish the 12V lead down the R pillar.

Thanks for the pics, now I can perhaps install the microphone that came with my stereo stock. The head unit is fine for what I need, but it be nice to have phone handsfree.

Nice work.

That is one thing I had to cut & splice was the bluetooth microphone because the stock Kenwood has a smaller jack than the Pioneer I swapped in.
The stock Kenwood should have handsfree (I didn't dive into the settings of it though) because it has the microphone already mounted. I need strong bifocals, so seeing anything that close above me is a challenge, and the Pioneer had an easier to read display I thought I'd put that in.

I have the monitor & rear camera set up & working but have been waiting to take pics until I get the tractor out of my shop...we have had nothing but rain for the last month or so & my field is pretty much a lake.

Mr. Carl - You just became my hero.
I recently purchase at T474 (arriving mid-Feb) and I would like to add the accessories below. By showing me the picture of removing the cab roof, you made my life so much easier. I'm eager to join the TYM crown as I've owned only orange my whole life.

A couple of questions if you don't mind.
1) It looks like you tapped into the "red" 12v constant wire from the radio to power your reverse camera which means it's always on unless you turn it off, correct? If so, was their a reason you didn't tap into the "blue" 12v switched wire you pointed out in your picture?
1a) Based on what I'm understanding, you grab your power from the radio and ran it to your rear camera. While that's not a lot of amps, did you think about using/needing a relay?
2) I noticed you replaced the front facing cab mounted work lights. Care to share any information on them? I planned on installing 4 light bars but noticed you put some beefy leds in place of the factory ones. Any thoughts would be welcomed.

LED Front Low/High Beams
4 LED light bars Front/Back/Right/Left - I do a lot of woods work and I'm in Maine. LED bars
Rear Camera w/ Monitor - very similar to yours.
Grill Guard - Grill Brush Guard

Thanks,
Matt

Thanks for the pictures, I have a 2023 474 as well my problem is I have a coolant leak from the heater unit in the cab. By looking at your pictures I know a nice easy way to get to the problem without having to ripe everything apart. Thanks

I'm having the same coolant issue, would you be so kind to advise your solution, thanks
