Few weeks ago I called New Holland to order the outter axel seals for the 48 8n. What I got was part # 8n4223A..I went to John Smiths website to go over the details on how this job is done. Well I first noticed that the seals that I got did not coinside with what the site says. Appears I got the inner axel seals used on the later 8n's? So I called New Holland and ordered the retainer assembly A8NN4248A and 8N4284 gasket and the 8N4225 gasket...Of which I had to order 5 of each at $6/each. Which is fine I can use them on a different tractor some other day. I would like to make sure I have the correct parts this time before starting. Anything else I shall need besides blue permatex?
