Tc 45 Da

I have a 2004 TN75A and the pump appears to be a 4 cylinder version of the VE pump used on the first gen dodges. To ge more juice out of them, you turn in the fuel screw on the back of the pump and pull the cap off of the diaphram on top and adjust it to bring the fuel in sooner. You can also rotate the diaphram to change the fueling curve. Not sure if this is the same pump on the tc series, but im guessing the tn60 is the same depending on year. The fuel screw is underneath a cone shaped tamper seal. Search around for the first gen dodge pump tweaks, there are some great pics and explanations.
 
take injects out and send em off and get em extrude honed a bit bigger works great and you dont tamper with the fuel pump at all
 
new holld uses alot of the same pump setups on the 130hp and less tractors. The problem with that setup is, they make it hard to get to the diaphram. That being said the smaller tractor wont have that diaphram/starwheel because they dont have a turbocharger. The tn60 does because it has a turbo, the tc45 wont. But they both will have a bolt that looks like a hexagonal cap. Take of the cap, while holding the bottom with a wrench. Under the cap is a screw. I forget what way to turn it for fuel but it wont be hard to figure out. ONLY A FEW TURNS GETS YOU FUEL, UNLESS YOU MONITOR IT OR HAVE A TURBO I WOULD NOT RECCOMMEND MORE THEN 2.5-3.5 TURNS. IF TRACTOR GETS WORKED HARD AND IT IS CRANKED TO FAR YOU WILL FIND OUT REAL QUICK.
 
The TN60's are 3 cylinder non turboed but I'm going to fix that with an intake and turbo from a TN75 and bump the fuel just a little. I'm not looking for gobs of power just a bit more than I have now without buying a new tractor.
 
I was thinking of the tn70. my buddy has one and the stickers are gone i just assumed it was a 60.
