Wanted to borrow hex tool for D2 J-series combustion chambers

Hi Neil I have one here in Ozz , but postage Would Kill You . Get a Hex socket the Right Size and Cut a piece out the Side so it Fits nice may need to Cut Socket and Lengthen it ,just can't remember .LJ

Hi Lance,
Neil is looking for the tool to extract the precombustion chambers and I think what you refer to is making a tool to remove the injectors...

Neil, I'm afraid I can't help you, if I had one of these, the postage from the UK would be very expensive also.
Best Regards, John

Thought we've been through this before....Just make one up using a 7/8" grade 8 bolt (1-5/16" head) with a few stacked nuts welded together.

John You are right on there , I must have had a Seniors moment there ,I borrowed a Tool to do one some time ago . A multi splined Bolt Type Tool , But I can't recall Tool Number , sure someone will Chime in with That No. Should still be available from Cat . You will need to Replace the O-ring seal which will be available from Cat . LJ

That's what I'm going to do but the reason I asked is I'd prefer to use the tool if it was easily available. Have ordered a 2 1/2" long coupling nut and a grade 8 capscrew. I think the nut may even be long enough by itself because with the lower edge even with the lower edge of the hex inside the chamber, the nut will protrude 1", which "should" be enough for a socket and rattle gun

$45.00 for a grade 8 coupling nut seems a little rich to me.

Such is life...

Here is the tool I made. I ended up having to pull the head as the injectors & precups were TIGHT in there! Heads on the ground, still have 1 injector & 2 precups in it. I ended up rounding the edge of the nut on the tool and the internal teeth inside of # 2 precup before pulling head. Motor was pressurizing the cooling system. #2 & 3 holes look like this. I'm afraid this head may be cracked.
