bowers25 Posted December 24, 2017 Report Share Posted December 24, 2017 Need help locating a replacement or cross reference a air diaphragm & a air nozzle for a Delta 40-540 16" variable speed. Just starting out scrolling, the saw was given to me. I have cleaned up all the rust and lubed it..........runs great, but no air moves across my work piece due to a dry rotted air diaphragm. Unable to located a new or cross reference part. Thanks & Be Safe! OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
jollyred Posted December 24, 2017 Report Share Posted December 24, 2017 Try eparts, they have parts for almost everything. Prices seem to be reasonable. They also show the blown apart machine, which is a great help in finding the part. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...

JustLarry Posted December 24, 2017 Report Share Posted December 24, 2017 Your best bet may be to get an aquarium air pump. I did this on one of my saws. Found one at resale shop for $1.00. Actually works better than the factory diaphragm did. Larry OCtoolguy, danny and twalsh1490 2 1 Quote Link to comment Share on other sites More sharing options...
loftyhermes Posted December 24, 2017 Report Share Posted December 24, 2017 My solution to this problem was to get a dogs squeaky toy, remove the squeaker and put the pipe in the hole, then glue the squeaker under the bottom arm.

crupiea Posted December 24, 2017 Report Share Posted December 24, 2017 I use an aquarium pump and tubing. If you saw really sow like I do the bellows are pretty much worthless. The pump is blowing a nice stream of air all the time. Cheap and works forever. OCtoolguy and twalsh1490 1 1 Quote Link to comment Share on other sites More sharing options...

crupiea Posted December 27, 2017 Report Share Posted December 27, 2017 Should be under $10 and that includes the tubing. OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...
Rolf Posted December 27, 2017 Report Share Posted December 27, 2017 (edited) As most have said go with an air pump. Even when new the blowers on the Delta saws were pretty lame. Although the squeaky toy idea is very clever. Edited December 27, 2017 by Rolf OCtoolguy 1 Quote Link to comment Share on other sites More sharing options...

bowers25 Posted December 31, 2017 Author Report Share Posted December 31, 2017 Thanks for the offer, it's greatly appreciated.....I'm going to try the aquarium pump or maybe a bait pump and see how that works.
