OK Guys, so here are a few more items to consider :
Failure #1 -- The hissing sound coming from Tranny Dipstick Tube, Air IN the oil ON the Dipstick, Failure #1 and Melted Fuel Tank #1 --- JD built these units with a gasket between SCV (#1) and the Tranny Cover --- supposedly when the oil gets TOO HOT (?) the gasket cuts the O-rings, the system sucks air, and the rear hitch fails to lift. OK--- if the 45-to-75 "E" Series has been out since say 2009 or so --- why hasn't JD authorized ALL DEALERS to take ALL UN-SOLD UNITS and take out the gasket and replace with gasket goo ---- BEFORE IT IS SOLD TO CUSTOMERS WHO PAY GOOD MONEY FOR A TRACTOR WITH WORKING 3 POINT HITCH ??????
Some dealers have also identified the Tranny Cover itself is MIS-Drilled in the oil port-hole between the SCV #1 and the tranny cover. This causes oil flow to not be as-designed, and heat up the oil. Not the usual culprit of the problem, but then why don't all dealers know to inspect the Tranny Cover for this possible failure --- INSTEAD OF BLAMING IT ON OPERATOR ERROR ?
"E" Series 83 HP & larger --- notice real closely --- JD RAISED the fuel tank mounting on the 83 Hp models and up, to where there is an inch-or-so of air space between the Tranny Cover and the Fuel Tank Bottom. GEE, did that just accidentally happen ?
AGAIN -- RECALL SUGGESTION -- in addition to correcting the O-Ring -to-Gasket problem mentioned above --- WHY NOT RECALL ALL UNITS, particularly those experiencing overheating problems, with a Modified Fuel Tank Mounting that raises the 45-to-75 E Series Fuel Tanks an inch-or-so above the Transmission Cover ????????????????????
By the way, if anybody cares --- I am about 5'10", and weigh around 170. The same I weighed in High School. I'm 59 now. It's NOT my FAT *** hitting the lever !!!! Also, I was raised on a corn & cattle farm. I am not some suburbanite who bought a green tractor because it was a cool color.
AND on that point, when I told the JD Rep with a poor customer approach that I doubted it was my fat *** causing the problem again and again, I pointed out what I thought were 3 significant points ---
1-See above comment about my body type and weight.
2-IF it were my fat *** bumping the lever, then it still shouldn't me MY responsibility OR my JD Dealer's Service Manager's responsibility to decide how to bend the SCV lever so a fat *** doesn't hit the lever !!! JD should issue re-designed levers and a service campain to all 45-to75 E Series tractor owners at no cost to change to the new , re-designed, "Fat *** Lever"
3-IF I had been disking with a 3 point-mounted disk, I could MAYBE see that I could have bumped the SCV lever on occasion, what with raising the disk at every row end, and dropping the 3-point after turnaround ----- But I was SHREDDING !! I dropped the shredder down a 8 am, and lifted it to go home a 3 PM, and the hitch didn't work
One last thing I learned by my inspection visits --- the 3rd replacement SCV #1 valve had some code-marks engraved on the valve, where it had been inspected at least twice, before it was sent to my Dealer's Service Department. So, does this prove JD KNOWS some of the SCV valves are sub-par, below spec, etc, and some are more-carefully inspected that the generic SCV valve placed on the manufacturing assembly line ?
Food for thought !
