D2 3J Precombustion Chamber Removal

Those are the correct tool numbers except it's for the early 3-3/4 in. bore not 3-1/2 in. Have no idea where you could find them...may have to make your own...basically a big sleeve puller that threads into the combustion chamber.

Thanks for the correction on the bore size...I have edited and corrected that oversight...actually, the print was small, and my cheaters must have fogged over...from searching for information...

hello CarlsCAT ,here the info on the tool you need ,you done a good job with the other tool ,this one mite be a bit harder ,i think you could sell a few if you get it right ,bruce oz

Hey, I Could Make Puller But Would Need Good Pictures With Dimensions And Another Pre Cup. Rob 417-258-2212 Leave Message

Rob, Thanks for your reply...Sounds like we may have to give you a call...Well, getting the dimensions of the inside of the precombustion chamber is the next step...Might have to check with a bolt supplier for something that will fit...
We've got to figure out what the part number is for the pre-cup...so's we can order some new ones if necessary... And to figure out how to fabricate some tools...
The Parts Man at the Austin Holt CAT-house told us that the San Antonio Holt CAT-house mechanics were the ones that restored the D2 3J1747...and to check with them for some info and help...
Anyone know what the part number of this pre-cup would be?
Thanks. Respy, CarlsCAT

My parts book shows:

For the later D3400
8B4440 Chamber
7B6868 Seal
4B5647 Gasket

For the early D3400
5B9658 Chamber
1A2298 Seal
4B5647 Gasket

I'd be real surprised if you could find either one of these new.
