Kukje A1100 glow plugs

[oldnslo]

Does anyone have a cross reference for the HT17160000A3 glow plugs used in the A1100N2 engine? I have performed multiple searches to no avail.

Marking on the glow plugs are:
OL3 on one hex
A52J 11V on another hex

M10 x 1.25 threads
17.5 - 18 mm heat tip 5 mm dia
Approx 25 mm from tip to threads
Approx 30 mm thread length

4 mm threaded electrical connection

You can match them by dimensions/specs

Shoot an email to NGK. They'll tell you what works.

Shoot an email to NGK. They'll tell you what works.

Tried that and their response was we do not have a part listing for the A1100N2 engine. Tried referencing the Kukje P/n and that didn’t work either.

I looked through the link provided by MT and found 3 with similar dimensions but nothing with all dimensions the same.

the closest NGK is CY57 5287 but not 100% certain would work. They do not provide specs on distance from heat core nose to threads.

Here's the Denso one maybe you'll get a better match.

Also does your OEM one have a manufacturer on it?

And Bosch -by dimensions starting on page 52

MT
Thanks for the additional resources.

The only markings I find on the original plugs are:
GP on one hex flat
OL3 on another
A52J 11v on another

Will look though the Denso & Bosch catalogs to see what I can find.

The part number you mentioned in the first post comes up as a Mahindra part that's absurdly expensive for a glow plug: this one appears to be available -I'm assuming you're looking for something more reasonably priced?

Yes, that is a ridiculous price for a glow plug. Watching my volt meter they get 12 Volts for xx seconds and shut off so should be just basic heating element. Going to keep snooping since it will start with two but misses for the first few seconds. Only need it if get heavier snow falls or for loader work so thankfully not a daily user.

I would think that a whole range of plug sizes would work. It just needs to get a heating element in the chamber that seals and doesn't have an interference fit with the piston. So what if the heating element isn't the optimal size or have optimal depth placement -any heated point in the combustion chamber is going to help initiate ignition versus a non functional plug.

I purchased a 2 cylinder tractor one time which started/worked just fine -when I replaced the glow plugs as routine maintenance later on I was surprised to find 2 different plug sizes.

If it was my tractor I'd happily gamble eight or ten bucks on the closest NGK part number betting on better starting

Update,
went to local Deere dealer on the chance they might have glow plugs in stock of similar size.

They had Deere Part number M87919 which is NGK Y702R. This shows fitting several models of Deere tractors and Gators.
they are approximately 8 mm shorter but have same 1 ohm resistance when measured with same meter at same temperature on my work bench.

the shorter height puts the body approx 1 thread from touching the head before the nose seats.
These worked on my tractor but strongly recommend you check fit on your tractor or engine.

As side note I did a search for Kubota BX2360 glow plugs and the picture I found with dimensions looked like would be an even closer dimensional interchange. Did not physically view one to verify the picture on line was accurate though.

appreciate all the help from the people that responded and hope this info may help someone in the future
