1986 ford 1910 crank question

[Qbangert]

Hi new here just recently bought a 1986 1910 4x4 I have a guy putting a new clutch in it. And who ever worked on it before screwed up the first part of the threads on the crank where the flywheel attaches I ordered a new nut and want to clean up the threads before putting the nut on. My question is "does any one know the thread size on the crank" and the torque specs for that nut. Any help will be greatly appreciated.

:welcome: to TBN. I only have a service manual for the 1900, but here is what it says, "Assemble the flywheel to crankshaft taper dry and make sure flywheel is correctly seated. Tighten retaining nut to 393-488 N-m torque.Use a dial indicator on clutch friction surface to be sure that flywheel is seated squarely on crankshaft."

The manual includes tractors 1100, 1200, 1300, 1500, 1700, 1900 and "Flywheel" section says, "All Models." I'm thinking the 488 N-m would apply to the largest model covered.

Thank you Fawken, your info is greatly appreciated. Found the thread size to be 40mm x 1.5
