(quoted from post at 06:16:20 10/23/19) "Jim where did you get that picture ?"
The picture is a cut from one of the parts pages for the power steering in the 303 Industrial Tractor parts book.
Tony, As I posted for you, a couple weeks ago:
"You can access the online parts books for them at: https://apb.agcocorp.com/login.aspx?region=NorthAmerica. At the bottom where it says Guest user click on view books. On the next page enter 303 (for the tractor) or 500 (for the loader), Check the box for Massey Ferguson and you will get a list of models that have 303 in their title somewhere, scroll down to chose the right one for yours. Click on it and you will get the parts book.
Also in the box where you clicked View Books is a link to the AGCO technical publications where you can search and find the Operator's and Service manuals (and Parts Manuals if you want) to purchase as hard copies or different electronic options for your machine."
You need to decide if the parts are right for yours, I can't beyond saying they appear similar.
Also one of your earlier photos showed part of an ID tag, looked like maybe it is on the engine. What does the whole tag look like/ have for info on it? You are looking for a tag similar to that one to ID the tractor.
thanks all that tag talks about is transmission , says sparkomatic or hydrostatic or something like that and tells me what type of trasmission fluid to add. i thought it was the model plate too , also since i cant find the exact model number i do have to go off pictures but i found a book where everything in it seems to be like mine https://www.ebay.com/itm/Massey-Ferguson-MF303-MF-303-work-bull-tractor-shovel-parts-book-catalog-manual/233191042965?_trkparms=aid%3D555018%26algo%3DPL.SIM%26ao%3D1%26asc%3D60709%26meid%3Dc8ad98a6b81d48789fc180edacbac0ae%26pid%3D100005%26rk%3D2%26rkt%3D12%26mehot%3Dpf%26sd%3D392420498966%26itm%3D233191042965%26pmt%3D1%26noa%3D0%26pg%3D2047675&_trksid=p2047675.c100005.m1851
