High pitch squeal

High pitch squeal

PostBy: BigFoot On: Tue Mar 04, 2014 8:56 am

I went to check the boiler this morning and I getting a high pitch squeal from the top of the boiler cant run it down to where it coming from .I oiled and greased all parts that gets oil and grease is there something inside the Head (where the coal drops down into the burn pot that moves fast ? ) :idea: Its not squealing all the time squeal starts off slow and gets fast and then stops and then starts over ,just cant hunt in down to where it coming from ? I think it coming from the top but cant be sure my boiler is in a spot as you cant get to one side (wall next to it )and on the other side my oil burner is close so the sound is bouncing all around and cant pin point where it coming from any thought s (oiled gear box, blower pulley box ,and head was greased is there a place to oil the ele motor that turns the pulleys (I think its sealed )? also checked bearings on coal tube and ashing arm

Could you use a mechanics stethoscope or even a long screwdriver against your ear to pin point the source?

Nice Pp, if it's WAY down somewhere--a long wooden dowel or even small long branch would do it--BUT---don't poke your ear out :clap: toothy Just tracked down a weird noise in my pick up to the belt tensioner using the dowel method-damn shame they don't give ya a grease fitting:(-glad it wasn't the alternator :)

It is prolly in the split brass bushing plates...my AA is doing it also.
Should shut down and disassemble for a inspection of rotating head pieces.

Are you using the wick oiler? I fill mine with 30wt and grease everything else the first of each month.

Oiling, yes.
Running a lot of fines now as I am near empty in one of my 1 ton portable bins.
Might be some fines are getting wedged in between the brass collars pieces and the rotating tube.

It more than likely is in the transfer head, as you guys suspect. Order a new cork gasket from AA before you take the head apart. I'll guarantee the old one is toast. About $18.00 +/- from AA. The fines are getting by the gasketed area and are in the bearing assembly. The noise is intermittent usually, but a shrill sound and frustrating. You do not have to remove the auger tube, because to top side is just 3 screws and 8 on the brass split ring. I started to mention that even with the oil wick used, the opening on EVERY single one I have worked on was plugged solid with a fines paste that has hardened. Tough environment to work in (wick oiler) hence when you remove it, I take the brass rings off also, and clean the entire assembly.

It might be wise to plan on changing out the gasket each season....only takes 15 minutes, and prevents lots of issues later. Looks like the cold WX won't let go, so take a few minutes' and do it today.
