Okay, CAT-Fixers !
We managed to fabricate a tool to remove the injectors from our D2 3J1711...Thanks to all the help from the membership...AND, these are the pre-cups we find...Not the style for the hex tool...1F-0479...
The Tool Group 5F-9217 ...that consists of 5F8353 Wrench, 5F9072 Spacer, 1A2208 Bolt, 1F7464 Bolt, L1017 Nut, and 4B4285 Washer...that I found on e-bay, are for the Pre-combustion Cups on later engines like the one on our CAT 212 Grader 9T2508...A drawing shows these tools are Precombustion Chamber Tools for 4" and 4 1/2" Bore Engines...
Stopped by Holt Caterpillar in Austin, Texas this afternoon and asked about this last Precombustion Chamber Removing Tool...for 3 3/4" bore engine chambers...
6B7224 Precombustion Chamber Removing and Replacing Group consists of:
6B7225 Wrench
6B1575 Assembling Tool Sleeve
6B1574 Replacing Tool Nut Assembly
6B1576 Replacing Tool Stop Nut
6B1573 Removing and Replacing Tool Assembly
2F1335 Removing Tool
Most all of these tools have been discontinued... Interesting note...restored D2 3J1747...sits in front of their Office...Just a little newer than our D2 3J1711...
So, got any info, or specs, of what to use ? Or where to borrow, rent, buy, or fabricate such tools ? To remove the Precups without using a torch ?
I've read previous threads tracking down info until my readers fogged over and my brain fried...
All help will be greatly appreciated...
Thanks. Respy, CarlsCAT
