Not to confuse this issue and if you have found the zerks then the problem is solved but I found a broken zerk on the top of my backhoe. I thought how simple is this to fix and I have stocked all kinds of zerks in my shop for years. Well much to my surprise these are close to a lot of things but not standard of anything that I had or after running around town could find. I ended up at my LS dealer and they showed the part number of the zerk but didn't have one which amazed even them. So I have to get my machine back on the road as I won't use it with out servicing it and out of desperation I took a 1/8" pipe tape - and I'm here to say it was the perfect size - and I retaped that metric thread to the standard ASE thread and it worked perfect. Just offering my idea if you get stuck and you have to grease your machine and finding that perfect 10mm zerk is impossible this is a great work around.
Just wanted to share my idea.
