Kubota L3430 - I have a new fuel (lift) pump. Looking at the pump on my tractor I am not sure of the best way to remove it. The two 10mm bolts are not easy to get at. Is there a special tool I need to remove the bolts. No room for a standard socket. Box end wrench might work if it was at about 45 degree angle. Any help on procedure for removing pump or buying the correct tools is appreciated. I have reviewed many post before this learning a great deal about my tractor. A lot of good hands on advice. I could not find any details about removing this pump except comments that it was easy.
L3430 Need lift pump removal procedure

I used a bent wrench. It came in useful for more than just lift pumps. Just pick up a cheap 10mm wrench and bend it as needed.
Thanks for a great idea. I would think bending them would be hard without it breaking. I would think cheap means thin gauge easier to bend. Does heating it up help? I have two generations of enherited tools plus mine. I can afford to bend a few. Not as many metric. I will give it a try and let you know.
Thanks.
Another related question. Kubota has a torque rating for these bolts of 35 to 41 lbs. When not able to use a torque wrench I tighten it to what I think is enough which is probably on the light side. 35-41 seems like of lot. Does anyone know how to judge more accurately without breaking the bolt?

The torque for the fuel lift pump mounting bolts is 8.3 ft. lbs, not 35 to 41 ft. lbs.
Thank you for the response.
I have attached a chart that I got the #'s from. I did not find a specific torque for the lift pump. A #7 is on the 10mm bolts holding the pump. Where did you get your numbers from? I would rather use specific #'s for my pump but it is probably a mute point since I will hopefully tighten it enough. I have a torque wrench but it

If I remember correctly, the wrench size to remove the nuts holding the pump on is 10mm. That would make the stud 6mm. If you look at your chart, 6mm stud or bolt in Grade 7 under ordinariness is 8.31 ft-lbs.
I used an old 10mm wrench I got from a traded-in Honda ATV tool kit, if I remember right. They are junk tools, but they bend easy. You can also use heat to bend them and that works purdy good so long as you have enough heat (it needs to be red hot). I don't own a torch but I have used a tig welder (no filler) to gently heat metal by just striking an arc and moving it around until the area was hot enough to bend. Crude but it worked. I had to make a tool to remove the clutch pedal switch on a B7610. That switch is buried, nothing you can do to get to it short of disassembling half of the tractor which I wasn't about to do, so I made a wrench to fit up in there. Worked excellent even with it's crude ways of making it.
Finally got around to replacing the pump. Bending the wrench did the trick. I bent the wrench without heating it up. Had it almost perfect when I tried to bend it a little more. It then broke. Got about 10-15% angle. As others have pointed, heat it up for more angle. It was good I bought two wrenches. The tracker now has full power again. Thanks for all the help.
