Welcome to LumberJocks!

Without a real picture of your planer, and model number; it is hard to answer your questions? :(

The pic above is an ‘AUTO PLANER’ which is a unique Taiwan model name, imported by many different folks. Defunct King USA in Florida sold many YHP-150 on east coast.

Not an expert, but have rebuild a couple different models over the years. Parts from those same 1980 model mfg are still available if you can find the Grizzly/Jet that is most similar. Grizzly models are easy to find, Jet requires more work as you have to find old 6 digit stock numbers (like 708538), and not use the model numbers.

Key differentiators are:

- Moving head with motor on top or Moving table with motor on bottom. Delta DC-380 was sold only motor on top. Lower cost imports (like Grizzly G1021) offered (Delta clone) motor on top for a only couple years, and then offered motor on bottom with moveable table to emulate the Powermatic M-0460213 model .

- Location of height adjustment wheel. Earliest Taiwan Auto Planer’s had wheel on top (like Grizzly G1021), but motor on bottom. Most mfg change to wheel on side and added rollers on top to pass board back and forth across the planer (like Grizzly G1021Z, cloned from Powermatic ).

- Country of origin. Of units I have rebuilt; Taiwan mfg 15” planers are near identical, but the Chinese mfg 15” planers have minor changes from Taiwan models and use different parts. The Chinese machines used a casting head that is slightly wider (~8-12mm). This means different length rollers, cutter head shaft, and gear box casting too. The bearings inside the machines are near identical, and all standard off the shelf parts.

- Planing speed selections. Some planers have same low (16fpm)/high (20fpm) speed as Delta. Some have a different speed (20fpm vs 30fpm, if brain is working today). The Chinese made machines all run faster. There are slow and fast Taiwan mfg machines. These changes create differences in the size of sprockets, and chain length on drive for feed rollers. IME – Grizzly G1021 parts should be compatible for slower feed speeds. Need to use Jet 15” planer parts for ‘fast’ Taiwan mfg planners, or Grizzly G0453 parts for Chinese made machines. The speed changes also have different gear box casting and they use different gaskets. Grizzly has scaled pictures of gaskets online, and have used their gaskets to repair every machine I have worked on so far?

Best Luck.
