Just seen this...
I repaired my servo shift last year. Got several manuals if you need them.
First did the electrical like you did. Mostly cleaned contacts and removed swarf and debris. Found a couple bad wire connections. then changed oil and replaced filter. Removed sludge and chips from bottom of gear box. Still sluggish shifting at best. Put a pressure gauge on pump line and found it way below 300 psi. The relief is just a hole in a fitting. got new fitting and put in a smaller hole to bump up pressure.
Now she runs and shifts like a brand new lathe.
BTW, I disagree with the fella about avoiding servo shifts. I trained in vo-teck in 1980 on this lathe and LOVED it. Went looking specifically for this lathe for a year and found one last summer. This is a seriously well made accurate rigid lathe made to run for decades.
