Wrong chambers...Are you sure that's not a 3T8706 glow plug number? They are 3/8" -24 tpi.
The 3H2033 glow plug is 5/16"-24 tpi.
On another note, is that chamber a decent fit? Often get a request for 12v glow plugs for the U-models which can be had in 3/8" - 24 tpi. The 3H2033 is only available in 24v.
I'm replacing the glow plug system on my D47U, ( due to the fact that someone before me removed all wiring ). I purchased new 3H2033 plugs, thanks Old Magnet for part #. There are no interconnection cables between the glow plugs, or wiring from the solenoid. I'm not sure what to use, or where to get connectors on the glow plugs themselves. Looks like connectors from old style spark plugs might work, but don't want to risk arcing/melting. Any help?
You could try a glow plug lead for a 3304 engine, part#7N9634 $51.72 from Cat. Have to check the glow plug end though, may be smaller.
can someone tell me if a glow plug will stop heating after a bit of time even though it still has 12 volts being applied!! this seems to happen on my Ford tractor
Thanks

It can certainly burn out like any electrical heating element. Check its electrical resistance (or, using an alligator equipped jumper cord hooked to the 12V, flash the 12V to it looking for a spark (probably around 10A current)).

The Fords have a heat coil in the intake manifold with a small fuel supply, these are only to be held on five to ten seconds then start engine. Glow plugs can be held on up to two minutes at below freezing temps.
Original terminals used a 9F8584 sleeve and 9F8585 collet. Don't know if they are still available.
In my collection of stuff I found some brass split type spark plug terminal connectors that work. I have a feeling they may be for some early automotive application that had larger than current style posts.
