Well i messed up. The problem is, the part number plate was missing from the bottom of the transmission so I was going by a picture of the trans and thought that it was a TT2421-1. I found a scribbled note in the back of the parts manual that came with the Dynahoe and in reality it is a TT-2221-1 Transmission. I don't know if this changes anything but all I know now, after looking at the trans cartridge, a 4 inch diameter filter will not fit in this canister.
More like around a 3.50 inch might fit. I don't know what Dynahoe used for filters back then as the only numbers that I have from the parts book are: 91107920 for the element and 68109710 for the "O" ring. I have had no luck with the Dynahoe group coming back with anything even though there are a few 490 owners in there and Joseph equipment doesn't have any cross reference info any longer. So I'm between a rock and a hard spot again with this filter. So, I don't know if there is a different filter size used between these two transmissions or not, I doubt it but at this point all I know is that the 4" filter will not fit.
Again, any help or insight would be truly appreciated short of pulling it apart to get a number. This would be the absolute last resort. Thanks, Dave
