  • Repair parts for 12x36 lathe

    I'm tring to get some electrial repair parts for my Harbor Freight lathe. I called Harbor Freight, but they are not very quick and getting back to me. I'm afraid that when they do, they are doing to say that they don't supply them. So with that said, has anyone found another source for stuff like this. I would hate to try getting them direct from China.

    Thanks,
    Steve

    Ignore HF. Replace anything electrical with easily obtained quality parts... but... what specifically are you looking for?

    Contactors, motor starters, switcthes, buttons blah blah... all available cheaply as surplus on ebay and other sources.

      All of the switches, contactors, etc in the electrics box are all readily available from places like factorymation.com.

        Or upgrade to a VFD and bypass the crappy chinese electrics all together.

          Grizzly should have spare parts, figure out what lathe of thiers matchs yours in control/etc config and then order the parts based on grizzlys online downloadable manual. (the part explosion photos)

            I put a VFD on mine mainly because the machine came as a three phase. I'll have to say, however, the wiring was very neat and looked quite professional and the components quite sturdy.

              I'll second that

              ABB, Square D, and Allen Bradly all good stuff that will gladly out live you

                No kidding. I have a B&S surface grinder from 1953 - same year I was born... Full of Square-D stuff that works better than me.

                  HF a few years ago had the contactors and the apron mounted FOR/REV
                  switch available for ~$50 for both, taking about a month to ship. The 3
                  contactors are identical, but wired differently, one each for FOR. REV and
                  INCH functions. You can use the inch contactor as a sub for the others.
                  Also the contactor coils are 24-28VAC and the xformer has 28 and 6V taps, the 6V used for the lights. The contactors on mine were wired so that the
                  coils saw 34VAC, it is easy to move the coil tap to the 28V tap and reduce
                  the coil voltage, should make them last longer.
                  The contactors are Chinese knockoffs of a Siemens original and as others
                  noted are not too hard to find and are generic. I hope your lathe is not
                  against the wall as getting at the components is hard enough with the
                  back of the lathe easily accessible. Download the Grizz pdf for their
                  variant of the lathe for a better set of pix and redrawn wiring diagram
                  that you can make better sense of. If you can afford it, a VFD/3ph
                  change makes everything in the electrical box unnecessary except for
                  the terminal strip at the bottom.

                    the little experience i have with HF parts are that they are cheap and pretty fast. Maybe the parts I ordered happened to be in stock or something, but both times I got my stuff in about a week.

                    That said, there's nothing (electrically) on these lathes that isn't pretty standard. The pushbuttons are all (on mine anyway) 22mm standards and if I ever did have to replace them I'd probably just get new ones from Automation direct (no affiliation, but I love their VFD's).

                    Many people on the internet like to bash harbor freight, and sometimes they deserve it, but I've usually had good experiences with them.

                      Thanks for all the info.
                      Here are the parts I'm looking for.

                      contactor CJX1-22 (3TB43)

                      thermal relay JR36-20

                      I tried most of the above mentioned suppliers, but nothing is listed under these part numbers. I assume that there are some compatible parts out there, but I don't know how to identify them. I might try going by Grainger with my parts in hand and see what they can do.

                      Harbor Freight has still not returned my call, after 1 week.

                        I would try HF again. I ordered one from them a few years ago.

                          I've never called them but I have emailed them and they were quick with responses for repair parts. The one time I bought something with a missing part from the local (60 miles away) (that really irks me to get home from a trip with a shortage) they shipped to me in a week. No questions asked and no cost.

                            Try emailing them about your request. I have usually gotten a response within a day or two that way. I have ordered parts for several machines over the past several years and they have always sent me the part. It may take a while depending on the part.

                            That said, I would also second the idea of replacing the box and motor with a VFD and 3ph motor. I did that with my 33274 and it was second best thing I have done with my machines (the first was doing the same thing with my mill/drill).

                              Try Grizzly -- if you insist on repairing the Chinese electrics, which I DON'T recommend.

                              3ph & VFD. The 3ph motor will outlive you. VFD failures are rare but easily and economically replaced if the need arises.
