Tools for spark plugs
Tools for spark plugs
I do not have the original spark plug tools from the tool kit, and am curious what tools are available to remove and reinstall the standard military wires and plugs? I am not contemplating converting to a civ ignition at this point, just wanting to check and clean.
While I am not near the 710K at present, I think mine may have an Austrian updated seat belt mount that are not present on the swiss models, possibly complicating access. I have looked in my parts book and don't see these mounts listed. Are these on the Swiss models? The mounts require holes that go through the engine cover (doghouse) and look like they would make getting at #3 a challenge, or even possibly have to remove the mounts themselves to get access.
What tools should I have on hand to get at the plugs and unbolt the wires from the plugs?

Re: Tools for spark plugs
THATS what that is. I couldnt figure it out! Weird and cool at the same time.
Tough to tell via that angle. I can usually get a wrench in there from below to remove the plug wires, then use the spark plug removal tool.

Re: Tools for spark plugs
The original plug wrench is pretty handy for the job. I'm at a bit of a loss as to what might substitute.
Interesting seatbelt mount. Never seen that before. I think I'd just ditch the mount, and carry on. It only looks like a pain in the arse.

Austrian refurbs got that mount, both sides. I think that is correct for all the refurbs.undysworld wrote:The original plug wrench is pretty handy for the job. I'm at a bit of a loss as to what might substitute.

Can't really ditch it, front seat belts are fastened to it.
And there was no tool kit in this truck thus no plug wrench. Trying to source a workable local substitute.

Re: Tools for spark plugs
I had to destroy the wires when I did my first civilian conversion. Only way to get a deep socket in there.

Re: Tools for spark plugs
Can anyone post the size/mm of the spark plug and wire connector? None of the books seem to list it and I am not near the truck.
13/16 plug?
Wire connector = mm?

Re: Tools for spark plugs
That seat belt mount is not too bad getting in the way for #2 plug as it is hollow underneath so you can turn the plug wrench inside it.audiocontr wrote:THATS what that is. I couldnt figure it out! Weird and cool at the same time.

While Mr. Missing Pinz-Toolroll is awaiting an epiphany on a fan holding tool, I assembled a few finds to go ahead and check the plugs as they sit and only got to #1 and #2 (the easy ones) before dark.
1. The military tool for removing the spark plug leads is ok/slow going. Seems to me the right angle bend needs to be about 2" or 3" closer to the head for what I did so far, and especially so for #3 and #4 which I did not get to.
From the parts book it appears the Pinz tool kit does not seem to have anything like this so I have no idea how you normally would go after the plug wires??
2. The 13/16 plug wrench substitute is Briggs & Stratton Spark Plug Wrench 5402H that is a bit long but works just ok, better when you can get a 19mm rachetless socket wrench on the other end. It needs to be a hair thinner especially where it is near the valve covers, so I may take a grinder to the part at that point.
I had to call it an evening before getting to #3 and #4, those look harder to reach by far. #3 probably by hanging from the ceiling and maybe #4 from underneath?
Any tips on those more skilled at reaching #3 and #4 plugs appreciated.
Thanks.

Re: Tools for spark plugs
That wire tool is not a part of the original tool kit, but it does a great job on the mil wire ends. I came to the same conclusion that the handle was a bit long and cut the handle off and put in a new bend to make the handle shorter.

Re: Tools for spark plugs
Modify like this. I never got around to it, but it was on the plans

Re: Tools for spark plugs
That bottom image is the kind of thing I've been thinking about. I just need some strong wire stock, a ground off crow's foot, and some time on the welder. Or does that thing already exist off-the-shelf for 19mm? I've seen images of them (below), but none for sale quite yet.

You may have to cut the handle down to make it fit the pinz space (or lack thereof). 19mm = 3/4"
As far as pulling the plugs after you get the wires off, the only tool I found that works on all the cyls is the original pinz tool or the one that Willi had @ SAV, in my pic above. Long enough to reach and then turn with a box wrench or the key. Austrian rehab pinz seat belt mounts really, really get in the way but should be easier on anything else.
A few times at this and you'll be wishing for a PinzSSI replacement

Re: Tools for spark plugs
Thanks for that ebay link.
I had zero issues with the OEM spark plug wrench adapter, and was easily able to put my torque wrench on the end of it to ensure proper tightness. Even the rearmost cylinder wasn't an issue. Uncle Steyr thought about this it seems.

Re: Tools for spark plugs
It's only the Austrian rehabs that have the new seat belt mounts (see pic above) that make 3 nigh impossible. I was going to consider removing the entire mount for any future plug service.ChickenPinz wrote: ↑Wed Dec 09, 2020 10:07 am

Re: Tools for spark plugs
My 710M is a rehab and has those brackets for the safety belts.
I have removed all 4 spark plug several times and fopund no problem with it. I guess that my tools are the original tools which came with the pinz from the factory - very simple tools, maybe not all tools in my toolbag are original but the spark plug tool may be. With the original spark plug tool it may not have been foreseen to use a torque wrench for tightening.
