Zerk fittings

[AKcold]

Anyone know a good source for the Zerk fittings on LS tractors? Dealer is slow to respond on this.

I've heard they are an off Japanese thread.

Already had responses that Amazon has packs of Zerks but these are a close US or British thread.

Usually followed by comment "close enough". Really dont want close enough though

I have found that 1/8th" pipe is the thread that has worked for me.

I bought an assortment of metric zerks. Various sizes and angles on Amazon for my Kubota

Best I can tell LS used as many different zerk threads as possible. What fits the backhoe does not fit the loader and other are different still. I adopted if it goes in 2-3 turns and stays put it's good enough. I know there is NTP, Metric and British, some taper some not. I tried ordering some but they did not fit either, guess I need on the thread id board and figure it out.

Yuk. I guess you can get a thread ID board and stock an assortment or you can carry a few and some matching taps.

Though I can't speak to your specific tractor I have found over many years of using zerk fittings that the threads of different specs are all very close to 1/8 taper pipe if the thread is of that approximate size. And that the threads on the zerk fitting are soft and so conform to rather than distort the thread in the machine. I have not yet damaged the threads in a machine using a zerk that was not quite right. I suspect that this is because not only are the zerk threads soft but also because the fitting only threads in a few threads, unlike a pipe fitting. It bugs me that there at least 2 different taper pipe fitting thread specs that are similar enough to 1/8 pipe to be mistaken for 1/8 pipe thread. And I am sure that folks in Japan and the UK who say the same thing. Spark plug threads were standardized over 100 years ago, surely they could have done the same with taper pipe threads. GRRR.

I've had a few zerks break on the BH, but they were M10 threads. I got a metric assortment at Harbor Freight that works fine for those. I've not had any break on the tractor yet, though. On other machines, I have re-tapped the holes to a more convenient size depending on what zerks I have available. There is usually enough grease in the joint to capture any metal chips, so not too much worry about contamination.
