Hello all. Just wondering if there's an aftermarket supplier somewhere here in the West for the gaskets on the transmission/rear end on a D4 7U, specifically the 3B0882 gaskets. The local dealer says they can't get them- something to do with tariffs?? Thanks in advance

I did end up finding a NOS set from an outfit in the East. Earlier I had gone on the Olsen website but only saw engine gasket kits. Since you replied, I did look again and read the fine print, which says that they can custom make seals. Thanks for your help!

When I rebuilt mine two years ago. I went through a similar search. For some items Cat has parts available. For everything else give Olsen's a call. There a a number of variants used over the years and the are great about working with you to get the right product to fit your application.

Cheers Keith
