Summit 19-4 x 60 clean, repair and rebuild.

[Ryanjax]

I was asking questions in a post about a manual but thought I would get a thread started to document my progress.

I picked up a Summit 19-4 x 60 lathe from a diesel performance shop that never got it hooked up because they didn't have 3 phase. It sat for at least 5 years and was backed into by a truck in the shop.

Here is the picture from the ad.

I called Summit to determine some information on it. The SN is 3243584, based on that it was manufactured in 1975. The SN is located on the ways at the far end by the tailstock.

It weighs ~5500lbs.
Uses D1-8 cam lock for the Chuck.
Spindle bore is 4.125"
The tailstock is a MT5
It has a 7.5 hp 3 phase motor

I rented a equipment moving trailer from sunbelt and loaded at the shop I bought it from with a forklift.

At home we used a come along, pipes and some equipment skates. I also bent my favorite pry bar trying to get a block of wood under it. This thing is heavy!

We parked her in the garage backwards so I can clean up the back side and check the wiring out.

Now I'm in the process of cleaning and degreasing to see how much rust their is. I've been using Simple Green and a brass wire brush or a scrub brush.

I got the QCTP removed and cleaned up in the parts washer then I soaked in evaporust. It looks like an Aloris CA size. I was happy with how well it cleaned up.

How does the compound come apart? I see a locking collar underneath and a small hole in the handwheel. Maybe a set screw?

I already removed the two gib adjusting bolts.

On your handle in the center is a cap, pop that off which should expose a nut or screw. Can the handle spin? Run the slide to the end of its travel off the base. Leadscrew will disassemble then.

Nice I picked up two of the 19-4's a couple of years ago that are still waiting for me to work on in my shop.

Looks a lot like my Summit 17-3.
