1st let me state my knowledge of tractors built for European sales such as your tractor is very limited but I was employed by a JD dealer for over 21 yrs from '66-'87. The parts photo for power steering housing for your tractor doesn't show the plug I inquired about. IIRC hole in 2nd photo is utilized to add oil to a manual steering housing. 3rd photo is manual steering housing but I think manual steering housing doesn't have hole at the bottom for supply line to attach. OK I'm confused!!!!!!! Can you supply a casting number from your tractors steering housing???
First, after this, I believed that you saved me unnecessary acquisition....
Please, take a look on the each photo, on which you will see the base of both pieces, with joins/pivots....
It is almost totally sure that the second hand piece is really a manual sterring, without oil pressure a.s.o.
Casting number - should be on the cast-iron piece? And - really, my JD 1020 is the european model one, made in JD's factory from Mannheim, Germany, from 1974.
I never doubted that your tractor was built in Mannheim. I agree with you I think the red arrow is aimed at parts key 24 of parts photo I posted for a ""manual steering"'' housing. I looked at parts catalog again and no casting number for manual steering housing is listed but these casting numbers are on PS housing( T25295 OR R77312)
You might want to remove the Half moon shaped cover on right side to see if anything is broken there. SInce you hit a hole, steering arm could be bent or broken. The steering valve assembly may be ok.
Are you refering to the pieces from the attached photos?!
And the part key 3 / the gasket - why is....against the oil-escape or against only the powder....
There cant be oil pression - thats whay I ask about this.... Tomorrow I will dissassemble that cover..... The steering is working, but almost only manually..... verry rarelly the PS is working.... Its seems to mee as if some piece sometimes tight or constipated...and moving hardly.........
