Well done for servicing it, that's not something i have ever tried personally, and as i am starting to stock these parts for sale on my website, for me personally id rather just replace them
The metering units are considered maintenance items. They're actually supposed to be replaced every year or 2. Maybe if you use synthetic oil, they won't plug up. On the mill I got a few years ago, not only were the metering units clogged, but the oil lube passages on the ways (box way machine) were also plugged up with congealed oil and graphite dust. Even with a grease gun filled with diesel, I couldn't get anything to flow into the lines beyond the meters. I had to take the whole machine apart and clean everything properly (and then I found bad turcite as well - surprise surprise when it wasn't getting oil!)
Yes these things get easily overlooked by most people when buying old machines, i certainly did not know to change them out when i got my first machine! and unless you know for sure they have been changed i believe its one of the first things you should do when you get a machine just as good practice, as the cost will be cheaper than a new ball screw or linear rails that's for sure Most of the damage to the machines i have owned or have bought for spares etc come from a lack of maintenance, ive started to finally look at the machines for what they are and that's money earners, so if you want to make a little money you have to spend a little money on their up keep otherwise it will cost you more in the end
Some good fault finding and maintenance work carried out which tbh should've been done over the years. Most shops run these machines to a standstill then sell them off.
Hi Marc , I have recently serviced my machine by cooking the meter units with a propane torch . I managed to save all of them on a vf3 .

They have a rubber diaphragm in them be careful of cooking them I imagine it would melt it.

Yeah i have come to learn that things need to be done even if the machines still performing well, preventative maintenance is always best
It's a very bad design from Haas! The metering units should be at the input Port of Oil, easy to change.
Yes it would be nice if they were a little easier to access
Great work !
Thanks
You are definitely messy, but no wheres as bad as myself 😅
Glad im not the only one then lol
@@kinzy_fabrications I've seen much, much worse. Where there are footpaths and the chips are like moss besides the paths :)
@@Panzax1you need to come to my shop 😂😇
@@crozwayne I'd love to come! Shops are great even when messy.
