Need part number for D6 9U u joints

Does anyone have the part numbers for the 2 u joints between the engine and transmission on a D6 9U17383 crawler?

Thanks,

John

3H0301 for the spider and bearing assembly. transmission end
3H7364 for the spider and bearing assembly clutch end
1H8499 for the complete unit.

UJ905 in the aftermarket world, for spider and bearings.

OM, thanks for the numbers. I was able to find some one Ebay. Local CAT dealer said the serial number was for a blade and I needed to get the correct serial number for the tractor. hehehe

Local Caterpillar wanted $115 for the U-joint but had non in stock. NAPA had them listed for about $90, but again non in stock. So, I turned to Ebay.  Found an excellent seller, excessinc, that had several and free shipping.  So, I got 2 U-joints delivered for about $80.  It is a little frustrating to install if you have never done it before.  First align the notches on the clutch output and the transmission input.  Make sure that you take a light hammed and push the small metal strap holding the caps on against the u-joint on the end.  Failure to do this will make it very hard to slip in the u-joint. There is not a lot of room.  And put the bolts in the u-joint caps prior to installing it in the tractor or you will find out that it is faster to install the assembly the second time around.  Don't ask how I know that. 😊 I have attached some pictures for your enjoyment.
