The larger diameter fan required that the radiator be lower that it's previous position. The transmission coolers are now higher up and more centered on the fan. The coach was then buttoned up and ready to roll. The temperature gauge has not moved since even on steep, long grades so this is the last of the steps to the Dieselfication of 1046! | Here Bill is finishing up securing the new radiator in place. | (1 Comments) This was being done at Bill Sitton's place in Ignacio, CO as he is a mechanic, has several FMC coaches and has all the tools needed. He is on the left and Larry Enoksen, on the right, is helping. | Next we reworked the fan shroud to adapt it to the new fan and new radiator. I went back to an original FMC brass radiator. That had the advantage of a better lineup of the fill spout on the radiator with the opening in the back of the coach. |
Here is the new fan mounted on the engine. | (1 Comments) I also elected to eliminate the viscus fan clutch. To do that we took the original GM clutch and put 3 bolts into it to lock it solid. To do this you drill through the outer case and the inner disc but stop before you drill through the other side. You then tap the holes and disc and then screw the bolts in. You do this one hole at a time to ensure proper lineup of the components. | ..... this fan. As you can seen, I upgraded to a 9 blade, 24" fan that will move significantly more air. At the same time, to ensure adequate cooling under all circumstances, I also upgraded the radiator from a 2 row to a 5 row. | After putting 30,000 miles on the coach in the last two years, it was time upgrade the cooling capacity of the coach. It was fine on flat land, but had inadequate cooling on the grades. This an earlier picture of the fan that I have been running. It was replaced by .... |
Its no longer there! We moved the coach under its own power out to the driveway for better access for getting ready to test drive. See where it went via the link in the Forum/Mechanics Corner/The Dieselfication of 1046. | Since I did not use the donor steering column, two switches that are on the gear shift had to be relocated. These are Eric's calculations of the resistance values that needed to exist for a momentary up/down switch to shift the transmission manually when it is in manual mode. Since this transmission is a 6 speed it would take 9 positions if each needed spot was separate. GM eliminated that need by having Drive, Manual and First gear positions. When in Manual, the rocker switch allows the driver to select a specific gear from 1-6. That switch is the original generator start/stop switch on the center panel of the dash. A push button switch was also added for tow/haul mode. | Here is the same picture taken with flash so that you can see what the driver will see. | (1 Comments) I love this picture! It is of the dash at night without the flash with the engine running. I will need to put smiley face stickers over a few spots to cover the lights for ABS, etc. that are not incorporated into the coach. I think it will take too long for the LED lights to burn out. One option would be to do microsurgery from the rear to excise the lights! |
