the new capacitor arrived today and drove back to the shop and installed . and set up for a resaw, and….. i was less than pleased- the motor was fried- done-kaput. called jet was told to send the motor label and as that arrived the engine will be on it ‘s way. we’ll see how that comes about??
now i did some exploratory digging around on my other one and some pictures are posted. my reason for this is just a heads up to keep an eye on the jet jwbs-18″. at the point previously to the melt down i was pleased with the saw. now… i’m cautiously optimistic. i’m hope things will back to normal. thanks again for everyones help ,staywell….. bear

No doubt, you're tired of waiting to get your saw back, but sounds like Jet is coming through no questions asked, yes? Ooooooooh, just took a look at those pictures. Nasty, nasty. Almost as bad as my contractor's saw motor when I got the saw.
Wonder if there's a way to spot these motors in advance -- some number or something?

I tryed to see your pics but a big YOU ARE NOT AUTHORIZED TO VIEW THIS PAGE came up. Why not ?
Try again David. There might have been a glitch with the Taunton server.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)
Im getting the same message.
Jet's taken control of your computer.
I knew it! It's a conspiracy by Jet tools.
There goes the doorbell.
They'll have to pry my Bosch out of my cold dead hands.
Bear,
It's fried alright, glad to hear Jet is helping you out.
If you take off the fan on the motor's end plate that's visible in the third photo, you'll see a sheet metal cover held by a couple of small bolts. The starter switch is under there. I'd be curious to know what condition the switch is in.
On the shaft there will be a couple of small weights pulled in by springs, they pivot outward from centrifugal force when the motor comes up to speed. The moving weights pull back a disc that presses against a contact assembly that is mounted on the housing. Chances are you'll find the weights jammed or the contacts welded shut, or some other cause for the switch to fail to open.
Hope it all works out, John W.
hey john- sorry for the slow response we were hit with a black out, i'm going to dig that motor out and see if i can post the points you mentioned. and i'll post tomorrow, thanks again everyone .....b
here you go john- they look pretty good to me , let me know what you think . still no motor at my door.....bear
That motor is very clean inside. Is it a TEFC? Is the centrifugal switch outside the housing, but under the fan? Delta has a dust collector or two with this arrangement, according to several posts on this forum, and the switches fail periodically (I seem to recall that they don't close, though, preventing the motor from starting, rather than staying closed and frying the cap and winding). At least they're relatively easy to change. Perhaps that's an area for regular maintainance, like cleaning and inspecting the mechanism and switch, going forward with your new motor. Good luck.
Be seeing you...
"That motor is very clean inside." Ehhhh?! What about those blackened copper windings in the upper part of pic #1 -- nasty. (Hope "windings" was the right word). That's what my burned-out Jet motor looked like on the free tablesaw.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)
I was referring to the lack of sawdust in the stator (windings, iron core, etc.). That, and the apparant start switch in the end bell, reminded me of Delta's TEFC DC motor, which has problems brought up on this forum in the past.
Or were you kidding?...Be seeing you...
My personal experience with Jet is that they have good support for the tools they make, but they make very low quality tools. They for some reason are sending you a new motor without any interest in what may have caused the first motor to burn out, thus no interest in making sure it can’t happen again.
"very low quality tools" in comparison with what other tool company?forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)
In comparison to any other brand-quite literally. if you take a good look at a jet you will find more than one moving high stress part made from plastic. That is not high quality to me. Brands like delta, mini max and general do not skimp on their parts to save money, and if they do skimp they charge less for it. There is no question Jet used to be a good machine, but recently they have been charging more for the name than for the quality.
hey g-i appreciate your honesty and actually a pretty good assessment of the situation. but trust me when i tell you i'm no babe in the woods . i know that if i got two years out of the motor, with a retro fit within that time . with a baldor perhaps, which would probably stress the bearings. which opens the proverbial pandoras box, to a whole new set of problems. the wheels and also the trunnions are also weak links . i got the saw on sale for 899.00 at woodworkers warehouse. ibelieved it was a 14" with some gratiutous 18" features thrown in. ashamedly i couldnt afford the mini-max , or agazzani(sp.) they we're my first choices. but the monthly financial grind didnt permit that. (i restore estates on long island). when i plug this thing in and ran threw some tasks mainly resawing old reclaimed 12/4 walnut and 100 yr old dougfir i was pretty impressed with the correct blade and direct 220 power (rewired by me). it worked excepionally well i thought. if you have anything i might be able to check or perhaps add to the saw . short of selling it or using it for a boat mooring and buying a 3000.00 saw i'm all ears ...cheers...bear

I certainly wouldn’t say that your jet band saw was not worth what you paid for it, but when people ask about comparing different brands of band saws or any other major tool for that matter, Jet seems to be thrown in with mini-max, delta, general and many of the other higher cost-better quality tools, when really they are not within the same league. It’s like comparing a moped to a Harley Davidson simply because they both have two wheels and take gas. My personal experience with Jet has led me to compare their quality with much lower cost machines like craftsman.
My opinion may not apply in many cases because I run my machinery 8 to 10 hours a day with heavy loads, so they must be built to last.
