This one is made from 100 percent natural rattan, which allows for a sturdier look and feel, but is adorned with straw flowers that are dotted with shimmery pearls to give it that little extra sumthin’ sumthin’. Some of the main products produced by the natural organic fiber crafts industry in Indonesia include: Rattan furniture: Rattan is a type of palm tree that grows in Indonesia, and its flexible stems are used to make a variety of furniture items, including chairs, tables, and storage baskets. At this point, only the shaft should be sticking out of the main pump casting. 5. Inspect the shaft for damage in the vicinity of the pump casting where the seal will need to contact the shaft. If you have any inquiries pertaining to exactly where and how to use women’s straw bags, you can contact us at the webpage. 6. Inspect the rest of the shaft for damage and carefully sand or file it so there are no sharp edges or protrusions to catch the new seal as it is slid onto the shaft. General inspection: Look for signs of obvious damage or problems that will have to be dealt with before the pump is used. If it has, the services of a HASMAT/DETOX center will be required – that’s not something you should do in your basement.
Everything you remove is to be discarded anyway (unless you’re installing your own non-Welch seal into the old cover in which case it will need to be in good condition and thoroughly cleaned of seal and gasket debris) so don’t worry about damaging the pieces but take care not to scratch or dent the shaft! 7. Make sure any sandpaper or steel wool particles are removed and take special care that they don’t make it into the weep hole above the shaft that enters the pump. Cleaning: Take a damp rag and wipe everything off – multiple times if necessary – to remove the layers of oil and grease. Then, maybe a damp rag with a little detergent to remove the residue. However, if the pump won’t get anywhere near the vacuum expected (less than a Torr for a single stage pump or a few microns for a two stage pump is realistic even if this is not quite as good as what the manufacturer’s specs may call for), all it may need is a little tender loving care. The primary and secondary were each wound «bifilar style» (wires in pairs) so the two halves of each winding have exactly the same number of turns.
I did find a nice brand-new Varian ion gauge tube in the same pile of trash but no controller. Note: Both pulleys can be pulled off at the same time without the need to move the motor, or just the pump pulley and belt can be removed by loosening the motor mount clamps and lifting the motor off its cradle. Use a soft brush to remove any dust, cobwebs, and other debris from around any cooling fins and the motor vent holes. 2. Remove anything attached to the inlet (or at least make sure it is open to the atmosphere) and outlet (which will be needed to vent as the old oil is drained and for refilling). The shaft doesn’t need to be mirror shiny but there should be no scratches or dings that will catch a fingernail. There is no guaranteed way to prevent this type of failure from occurring though running the pump until it’s nice and hot before disassembly might soften things up enough to become unstuck.
Nice little pump. I have a couple of 1405’s (or is it 1402? Anyhow, next size up from the 1400) here which have a note painted on the outside indicating that they were overhauled back in May, 1954. They sat around in the back of a CRT rebuilding shop for many years before I picked them up a few years back. A thorough external cleaning, and a couple of flushings and an oil change should get rid of most of it but how will you know how much remains? Fired one up, flushed it out a couple of times, and refilled with DuoSeal oil. Just pump your system down as low as it will go with your electronic vacuum gauge hooked up, and spray a little helium at all the suspicious points in your system. Assuming there are no external leaks, the short list of causes for poor vacuum performance are old/dirty/contaminated oil, low or no oil, open or defective gas ballast valve, sticking internal parts due to buildup of insoluble varnish/gum on pump chamber or valves, and then finally, damaged internal parts. On mine, the old seal assembly came apart but there was an aluminum ring which had to be freed using pliers in a twisting motion before most of the parts of the old shaft seal would come off.
