D4 &U Air Cleaner Seal

is it the gasket were the housing bolts on or the sealing washer for the precleaner. is yours a oil bath or cartridge type.

It is the seal where the oil cup mates to the main body--my 6U1-up P/Book shows the same 7B5716 seal, bracketed with the P/No of the main body of the A/Cleaner.
If the P/No updates then Cat Parts Dept should have the superseded number in their system.
When I locate my old Cat "O" Ring book I should be able to give you the dimensions if you are purchasing aftermarket.

Mine is the oil bath type and is the one that Eddie mentioned. I was not sure if Cat parts would have changed the part # or not. Some of the new guys at the parts desk do not always seem to be too helpfull with the older parts. I will check with them. I did find some on ebay and some other after market sites that I will check out also.  Thanks guys.

Hi Bruce
I will have a look when I get home for the number

Hi Team,
knew I saw this recently--scan below tells of the seal position--despite how it looks in the picture the "O" Ring goes around the outside of the upper body up against the step that the bowl clamps against--the "O" Ring is shown part assembled/fitted to the upper body and a loose section is hanging down--you need to blow up the pic to see what I am saying.
Cheers,

Hi Eddie, I guess we can assume the reason Cat added the o-ring - was there guidance given to retrofit them to prior tractors that have the same type of air cleaner arrangement?

Thanks all for the info. The last time I serviced the air cleaner I just reused the old O-Ring, looked to be in good shape. I should have known better and replaced it because it has always weeped a bit of oil. Never did get it to seal good. Not sure if it was original cat issued or not but seemed to have a bit too small of a diameter to seal properly. Has any one had good luck with any of the after market ones that are available on line?
