Ok, So the old seal is nearly an inch thick and the image on messicks shows a standard thin oil seal! I can find no oil seal listed that fits this application in either a timkin or national oil seal catalog so this has me stumped!
Now for the two main questions,
1) Can I fit two seals in the holder or will only one fit?
2) Does anyone have a number for the oil seal itself so I can simply order it the a parts store for less then IH wants?
Nothing against IH but they mark some parts up by 300% or more!
