Do a search on BLOWER OIL, but here's the thread...
Most of the convection and combustion blowers are very similiar in design, and should have the oil holes, however, depending on mounting, the hole may be on the bottom. Sometimes you have to take them apart and clean the blades and tighten the housings. The blades to get dirt/crud build up and will cause them to go out of balance, causing a vibration. (see my pics on the below thread...) Screws do come loose sometimes. Good luck!
Blower fan?
