Very useful. We have four TN series. I am having a similar issue on a TN55. Can't seem to get it started. Initial thought was the fuel shut off solenoid. May tear the lift pump apart to see if the check valves are floating. Great advice on the lobe position. Thanks!
I'm having a similar issue with a TN65, hard starting, Iv'e loosened the purge nut on the top of the filter and get some air bubbles, then a good flow. Tractor starts better, then after shutting it off, back to hard starting. I have noticed that fuel seems to be draining back into the tank, or what seems to be the sound of it. My question is if the mechanical pump maintains pressure after the tractor is shut off, to keep fuel in the line going to the filter and from the tank. Anyone got any input on this, spent a whole day trying to solve this issue. My next step will be your suggestion, replacing the pump. Thanks for posting this, best regards!
Hi Carl, nothing special as far as I could determine. I just positioned the pump onto the studs and when tightening the nuts the lift arm will position itself with respect to the cam. So, just take the old one off and install the new one. My tractor now starts like it was new!
Just what I needed to fix my holland
Thanks Dr

Any special tricks to line the arm up inside the engine or does the new one just go right in?
