Working on dads tt still set the engine in the chassis , pulled the plugs , they are GETS "776" ? Never heard of them , wondering if any of you have ? Just curious . Hope everyone is well and having good fun/times with their Ts , hoping to get our tudor out for a turn or two around the farm soon !! Thanks.
I'll bet Constantine or one of the other Plug gurus can tell you all about them. He told me the "775" on a Molser plug was probably the core number and different plugs used the same core.
Neat plugs and good to have 4.
How can I test them to see if theyre good enough to use ?
The reach on them looks long for a Model T. They might work OK, if the electrodes and porcelains clean up.
On the other hand they look to be rusted solid, so no way to take them apart for cleaning. Might be better to sell them one at a time on eBay and invest in a better set of plugs.
Neat plugs! The "775" is the porcelain manufacturer, Frenchtown Porcelain from Frenchtown, NJ. I believe they started producing plugs in 1915. There are thousands of different plugs with "775" on them. They would (and did) produce any name a person wanted.
These Gets were popular to add priming cups to the side. The long reach on these would certainly put the spark down in the cylinder, just be careful with a higher compression piston.
As has been mentioned, the 775 has to do with the quality of the porcelain used. The plugs reach look similar to an old Champion 34, quite often marked "Gas Engine Special", commonly used in Maytag single cylinder engines.
These folks may be able to give you a bit more:
I don't know how to find it, I think I saw it on here somewhere but can't remember. There was an ad for Champion spark plugs and they made those long reach plugs like that for some T era car. I want to say for a Metz but maybe I'm just thinking that because of the name Getz. I remember thinking that if you had one of those cars it must be a problem finding plugs.
Not sure if theyre rusted solid or not , I was actually surprised that they came out of the head lol ! But they did so fairly easily , I will try to take them apart , gently . They were in a 1925 engine so Im assuming they were running at one time . The electrodes look ok , not burnt off or anything . We shall see I guess . Moving forward on dads project TT , so theyll probably be shelved for the time being . Keep trying to talk him into running coils , but this engine has a bosch front plate distributor that hes adamant about using so...guess im going to learn how to hook that up . Does anyone know the way to wire them up ?? His first T project so Im going to have to let him have his way any tips would be appreciated . Thanks again guys .
At some point I heard that those long plugs went into Willys Knight engines - not sure where...
A distributor ignition is easy for anyone who has tinkered with 1920's to 1970's cars. Here's a link about VW, you can find a schematic picture there that shows how 1960's Bosch stuff worked - but other distributors are much alike.
When you take the plugs apart, first soak them in penetrating oil. Next, clamp the nut in a vice with the porcelain facing down. That way you can apply torque to the plug base and you won't have to worry about dropping the porcelain.
I think some of the early 1 and 2 cylinder cars used long reach plugs. The extra hex length may have made them easier to reach on cars with engines under the bodies. My Buick's terminals are very close to the push rods and some extra length might be better there.
Myself i would not take them apart but use a bead blast or a old spark plug cleaner? Bud in Wheeler,Mi.
Buicks had a bakelite type material tubes which covered the portions of the push rods near the spark plugs, to prevent arcing. Here's a shot of my 1906 Buick, which has these original tubes. The wires to the timer also run in a bakelite tube, along the frame. Would be pretty simple to make. My friends with early Buicks had never seen these before.
*Sorry about the thread drift... *
Thank you Les. I didn't know. They are great cras aren't they.
Will do Royce , theyre up on the shelf for now , so they dont get lost in the abyss of the shop hopefully ! Thanks for all the input everyone , at first glance I had originally thought they were in adaptors of some sort , the TT is a 25 that we salvaged from a scrapper , so wasnt expecting them to even come out .
I think I have at least one.
The Gets plugs are great looking and popular among collectors, although they are fairly common. Best thing to do with them is clean them up and put them in a display case. As a long-time plug collector I've restored quite a few early plugs and found the best way to take them apart is to use two box end wrenches, one for the body and one for the packing nut. Squeezing the wrenches together usually does the trick. I always avoid clamping any part of it in a vice. Don't want something to slip and break the porcelain, or turn the nice round packing nut into an oval. The 775 porcelains are indeed made by the Frenchtown Porcelain company. The 775 was the designation for their formula for the insulating material. As has already been noted, there were thousands of different brand name plugs made over the years by Frenchtown. They were special order for garages, dealerships, auto parts stores, and anyone with a neat gimick.
