Help 9x20 HF lathe

[Ivanveg]

Just purchased used. (have a 13" LeBlond). Did download and read the manual twice. Question:
1) I assume the v-belt should be installed with the V in the pulley groove. Not how I got it.
2) The feed chart refers to a lever "A", "B" and "C". Cannot find those levers. I have a tumbler with nine holes.
3) While the "Gear Engage" on the apron did move during the demo, now it does not. Don't want to force it.
4) Where can I buy a spare high quality belt. Preferably on-line

Thank you for your responses. Ivan Vegvary, Sandy, Oregon

A, B, and C are the pulleys. You place the belt on those depending on the speed you want the chuck to turn… One big lever to loosen and tightening the belt.

Thank you Wachuko. I understand the A, B and C pulleys. They change the speed of the chuck spindle. It's the "feed rate" (longitudinal) that I don't understand. The chart lists levers a, b and c (not capitalized). Where are these levers. Or is this simply bad English on their part?

It could well be a poor translation (likely) or it could be in reference to the levers on the cross slide apron. There is no disable lever for the lead screw, just dropping the banjo. I drilled an extra hole in the change gear box for the lever to live in when it was dropped. Automatic cutting and threading use different gear ratios, hence different levers. Look for a picture or reread the instructions until it makes sense is my suggestion.

My machine is a Grizzly G1550. The drive belt is a Gates 5M730. Other names have other sizes, all 5M series, some as small as 710 mm total length. Some as long as long as 750 mm. Taking the belt to a Gates dealer and have them match it for the first one will save having all those misfits lying around. Or just cut it and measure it if you have a backup machine. The 5mm belts are surprisingly strong. But if one has been used on its' side, replacement is highly recommended.

I see what you mean... not levers, they are referring to gears...

I wished mine had that gear changer set up !!
