Parts compatibility between the Shen Jey 1740G (7.5 hp 2-speed motor, 32-2,000 rpm headstock) and current Eisen 1640G (WinHo 17" 430mm). I will keep this updated. If you are a Victor owner, let's open an equivalent Victor compatibility thread.
Most of the basic chassis elements look to be exact matches (basic components like bed way size/geometry, lead screws, motor mount/tensioner, belts/pulleys, some of the back gears, basic structure of the headstock (where bearings would be), handles, buttons, motor physical size and mounting specs (no longer have dual speed). These are areas where there is likely more compatibility.
Note: I recommend the Eisen (WinHo) operations manual if you have one of these lathes. Eisen will provide at a reasonable price. Check out the Eisen Machinery web site and compare specs. If your Osama, Millport, Victor, Kingston, etc. share basic specs vs the new machines, this may be the best place to go for replacement parts.
Standard Eisen Parts Compatibility
Wipers for tailstock (Eisen Part Numbers 31/32, 38/39, are compatible - 2 sets of each)
Wipers for carriage (Eisen Part Numbers 11/12, 20/21, are compatible - 2 sets of each)
Note Cross-Slide wiper (Eisen Part Numbers 47/48 is NOT compatible)
Band Brake for Motor (Eisen Part Number 24, is NOT compatible. About 1.5" short. Designed for a smaller rotor. In a pinch you might be able to cut the bolt off short and connect another threaded section. Be sure to ensure there is no metal to metal contact from band to Rotor - the brake material is a little shorter.).
Ball Oilers (Eisen Part Numbers 55/56/57 ... if you ask for the ball oilers they will provide them) are compatible. These are 6mm but have the flange on top and won't fall through the hole. The Eisen versions are also compatible with the nozzles on most/all of the Goldenrod oilers (seals and properly injects the oil - nice cuz ball oilers generally suck).
Belts: Gates Hi-Power II B68's fit fine. I have 3.25" and 7" pulleys. The old belts were Gates Hi-Power II B70's that were too long.
Accessory Eisen Parts Compatibility
Eisen accessory - micrometer carriage stop is compatible. And quite nice - heavy, robust, 1.5" travel and has a nice .001" scale with lock. Pricey.
Note on Design Changes for New Model Eisen 1640/1740 Lathes (and potential for incompatibility)
The lathes made to this design pattern share many component parts that may be compatible with new Eisen (WinHo) lathes. Most/all of these legacy companies in Taiwan, whether builders or branded exporters, are out of business. Eisen still imports lathes following this design pattern but designs have continued to evolve. As an example the Eisen 1640/1740 share most of the specs with these older machines. The 1740 has a D1-8 spindle, over 3" spindle bore and 10hp motor standard.
Here are a few places where Eisen has made changes that may effect compatibility:

Here are a few places where Eisen has made changes that may effect compatibility:
- The cross slide has been "robustified". Dimensions have changed (taller and wider with a more robust dovetail). The compound doesn't look bigger but YMMV
- The spindle has a separate leveling/balancing function.
- Headstock gear ratios updated (speeds from 20-2000 so gears/parts compatibility might be sketchy).
- Current models don't have dual speed motors - use a separate high/low gear in headstock. Later model Shen Jeys used this design as well.
- One-shot lube mechanism has moved to the opposite side of the bed (out of the line of fire of chips).
- Tail stock has 6" of quill travel (vs 5" on the 1983 model)
- Brake rotor (integrated with drive belt pulleys) is smaller.
