Just purchased a CVA lathe - looks to be in very good condition.
Similar to the Monarch in most respects.
It uses the same Sundstrand hydraulic drive but has manual speed selection for some strange reason. I think CVA stuck with it right through production.
Anyway the last owner had looked after the lathe - topped everything up EXCEPT he knew nothing about the drive! The oil sight glass was filthy and black. Cleaned it off no oil showing. I was very concerned - also a small leak inside the bottom pulley.
I drained the oil out - thick as treacle - probably iso100 not 68 as the CVA manual is ambiguous. Thought at first it was empty but after 3 hours there was rather a lot.
Refilled with 5L of iso68. Still not showing on the sight glass.
Anyone know how much these things take? And is an oil leak from around the pulley locking nut anything to worry about?
Thanks - new on here so please be patient!
