I am looking for a source for Rear Crank Shaft Seal for a 450 diesel D 281 engine and also the lower gasket set.....I talked to Dave Moore and he can't find any, so I am looking for another source. Thanks

It's going to be tough. Parts for those engines are just about gone. Gasket maker will work for the pan. I hope somebody can help you. You've tried Steiner's?

my local auto store has got seals for me by the demensions, might be worth a try. I've also saw web-sights that offer the same thing

What about your local CaseIH dealer?

I am going through that on a late 400 right now.The pan gasket 52001D is still available through the CIH dealer,and the rope seal halves for the early engines are still available,but are not long enough to fill the seal retainer grooves,so I ordered two sets of the rope pieces.I just ordered them,so I do not know how that will work yet.I do not know how to give dimensions to find a will fit two piece seal to fit into seal retainer to see if that is an option.

Those seals are discontinued and getting hard to find. Can still get the older rope seal but the D450 crankshaft doesn't have the spiral oil groves to work correct with the rope seal even if the rope seal retainers were added to use the rope seals. Maybe check with webers tractor works but don't think they had any the last time I asked.
Lower gasket set can still be had from case unless dropped recent, number 332653R92. Bought my last one from E.B. for around 100 less than Case, same set. Doesn't have the 271794R1 rear oil seals you need though.

Cushman you probably already know part of the D264 engines got the same rear seals as a D450, D264 engine # 13482 and up. Rope seal retainers have 4 numbers before a letter, other type 6 numbers before a letter. IH also made change packages for changing to newer seals for MD through 450. Trouble is if changing back to rope on those engines is the sharp edges on crankshaft spiral groves were to be smoothed up when change was made. Just wanted to make sure you are using rope in rope retainers. Don't know if lucky or unlucky but had 2 MD and 2 SMD with the changeover seals in the past.
