Brown and Sharpe 510 clogged Bijur system
We recently picked up a nice little Brown and Sharpe 510 surface grinder that was in great shape, partially because it had sat for many years. I replaced the 'o' rings on the opti-flex drive, and that was about it, except the oil lines on the Bijur one shot system are clogged shut. Any easy way to flush these out, short of removing every tube?
Thanks in advance.
Hi- just bite the bullet and replace all the metering units- you can order them from Bijur or Lube USA . Not even worth trying to clean them out- they wont work very long even if you manage to unclog them. Clean the pump reservoir and check the filter at the same time.
+1 on the replacing the metering units. They have a filter and a check valve built in that makes cleaning them almost impossible. I know, I tried.
If the pump is like the ones that i have worked on, there is a filter on the end of the pump that can be removed for cleaning. Before reinstalling the metering units make sure all the lines and fittings are clear.
If its plumbed in copper then clean the lines, if its nylon probaly best to buy some of the correct compression olives and just plumb afresh (olives are dirt cheep + the tubing is probably less than the cost of solvent to clean the old stuff). The nylon lines gradualy go brittle with age + there dead fast to run, can normally just slide - pull it back thorough all the pipe clips with out even removing them :-)
When replacing the meter units pay attention to the sizes and where the go(they are marked).They are sized to distribute the correct amount of oil to each location so don't mix them up,although a grinder won't have that many.
Thanks for the recommendations. The lines are copper, so it looks like its down to replacing the metering units and cleaning the pump and it's filter. I was hoping for a simpler flushing of the lines, or some such thing, but it sounds like that is not really an option with check valves in the metering units. Any tips on how to flush the copper lines? It almost just seems simpler to keep the pump, and replace everything else.....
buy the metering units from Bestline in westminster So Cal. They have a website Bestline Products - Home Page they have very reasonable prices and great service.
