Hi, I am looking for some help on a part number/size of a seal. We are doing the brakes on a 1980 Allis Chalmers 5050 and need to replace the seals inside the right and left support brackets. On the Agco parts website it does not list this seal, just the support as one whole part. Could anyone point me in the right direction on this? Thanks, |

Thank you both for the help. That was indeed the part and fit in perfectly. If you could help with one more question. So on the 5050 it does not have an O-ring that goes around that differential cover. When I removed I did not find any hint of a sealant between the steel shims and the tractor. When re-installing should i put a bead of Permatex on this or is it made for the steel shims to seal this section. I feel like I should, but since i didn't find any sealant in the removal I wanted to get others opinions. Thanks,

| You'd think they would have had something for a sealer. And if the bolts are a thru hole, you need some goop on the bolts threads. |

| Wasn't leaking was it? Seen thin shim set ups that used no sealant. I'd use light grease if anything. Much sealer could effect shim clearance setting. |
