Whats up guys, I have a slight noise problem with a 6" hydrofarm inline fan. Its a little past warranty and all it seems to need is some oil, its squeaking really bad. I have torn apart the entire fan and im down to the actual motor, the only problem I see now Is it's a sealed unit there are no oiling holes or anything I can see to dismantle the coil and get to the bearings and shaft. Has anyone dealt with these on this level? I dont feel like spending 100$ on a another fan I can hopefully fix. It seems like they dont want you to be able to fix it.
Edit: I have figured it out so I will show you how to take it apart.
So you have a bad fan thats old and dry?
Step 1: Disassemble the electrical box, Make note which wire goes where for the capacitor. I marked on it with a red marker and on the terminal.
Step 2: From left to right the wires for the blower were: Yellow - Brown - Black - Blue, Capacitor was hooked on Brown and black.
Step 3: Take apart the outer case it only has a few screws on the outside. The case will then slide apart.
Step 4: Take out the blower and support there are 2 screws on each side holding the support bar in place.
Step 5: Take the blower off the support by removing the 4 screws on back.
Step 6: You now need to get the center back cap off somehow, I ended up pressing the center shaft down slightly till it popped out on its own.
Step 7: Once you have pressed the shaft in from the front the back will be exposed. You will now see the hardware holding it all on. Notice the c-clip.
You have 2 clips, the C-clip and then the retaining clip under it.
Step 8: Remove the 3 washers in order and try to keep them in the same orientation they came out.
Here they are:
Step 9: Now that everything thats keeping the coil from sliding off is gone. Proceed to gently pulling the coil out. There are 2 bearings pressed into the coil both are singapore NMB 608z, both of which are easy to press out. Not sure why I can only have 10 photos but the rest seems simple, pull the bearings off and clean them or replace them clean up the inside and shaft and grease everything. slap it all back together. Brand new fan.
