Could you possibly grind down your 22mm box end wrench in the area of interference and still maintain wrench integrity?.....or perhaps give it the crows feet wrench look? I like PB blaster the best.
Thanks, yes I had thought of that, but...
..well, but since the thing must have been assembled somewhere ...I guess I'm not taking it easy that it needs special tools for every little thing.
North American manufactured things; maybe.
Korean manufactured things; I hope can still be repaired with hand tools (-:
I went to Autozone again and got a much closer look at their 7/8 O2 removal tool.
It turns out that the CARD it is on is marked 7/8, but the tool itself is etched 22mm.
Not their fault, Great Bend makes it and packages it that way.
So I bought that and FINALLY used it this morning to get all four injectors out.
The manual is WRONG, they are NOT keyed into the head at all.
The 22mm is the base of the injector body, it is not a hold down nut.
The local diesel specialist place told me all four injectors were "junk".
Said they couldn't get a decent spray pattern out of any of them, didn't know if they would be able to get parts to re-build them, but their off_the_top_of_the_head estimate was somewhere around $75 EACH.
Somewhere he said that bad fuel was the most likely cause.
I might buy it 6 gallons at a time, but it is where I also fill up my duramax and it is a fairly high volume station.
OK, I wanted to go to my dealer anyway, so I called.
He was in the shop half under a tractor but guessed new injectors were about $25 each, then started quizzing me.
I showed up 1/2 hour later and he tested the glow plugs - all OK.
STRONGLY disagreed on the injectors and sold me a fuel filter - which I probably agreed to partly on the suggestion of the injectors guy.
So, it is 3/4 back together, the only hassle I anticipate is having to bleed the air from each of the high pressure lines. Tomorrow's task.
The good news is that I have gone through the exercise of pulling the injectors and glow plugs, know which tools, know the sequence, etc.
As with many hardware (and software) things, often just taking them apart and re-assembling them improves things considerably - IF DONE RIGHT (-:
