* TEF-20 Torque settings
Posted on November 4th, 2008 by ploughmyfield.
These are the major torque settings for the Ferguson TE-F 20 Diesel.
There are not a lot of torque settings, so for the other bolts the second part of this table is useful as it gives general torque setting for the smaller bolts

comment from Jón (FOFH forum member)
In the Massey Ferguson TE-20 Service Manual. Engine section page C.1 says: “Screw threads should always be lubricated before tightening” i.e wet torque.
comment from Elevensixteenths (FOFH forum member)
Going on from what Jón correctly said about wet torque, it’s wise not to fill the head stud bolt holes (or any other stud hole) with oil lest, on tightening, a hydraulic lock occures which can split a casting. I mention this just in case an inexperienced reader tries the ‘flood it’ wet torque method.

What torque should the back and front wheelnuts be set to?
June 13th, 2011 at 9:21 pm
For any bolts that haven’t got a specific torque use the general recommended settings at the end of the article.
i.e. front wheel nuts are 7/16″ UNF 40-60 lb. Ft back wheel nuts are 5/8″ UNF 60-90 lb. Ft.
