Hi Everyone,
Went to put some grease into the zerks on my Jinma FEL and found the grease squeezed out around the nipple, none going inside. Bought a new grease gun end fitting - still no improvement, same problem.
Took grease fitting out and tried to identify the thread type and size. This is where it gets strange. The grease fitting has a metric thread of sorts but is very fine. I have both metric and imperial grease fittings (spares) and the Jinma one does not match any of them. Has anyone been able to identify the fitting size and thread?
Reason I ask is that I really don't want to drill and tap to install better zerks, however, I guess I am going to have to if there are not any worthwhile replacements. The zerks that came with the FEL have the nipple a smaller size than would be the normal standard (imperial or metric) and I haven't yet found a fitting coupler that will work with them.
By the way, the zerks on the Jinma 554 tractor are fine and I have been able to grease these without any problems.
Maybe this is just another anomoly with the chinses tracor that needs to be sorted out.
Thx for listening to my gripe!
