convection motor oiless?

Jon_M · Sep 12, 2012

Last Friday I had the Company I purchased my Enviro EF2I Insert (Mfgdt. 2008) from last year do a yearly cleaning. ( I should have listened to members here and did it myself.)

Before the tech was finished I had asked him about putting a couple of drops of oil in the convection motor and he told me that was incorrect because Enviro changed the bushings to be oiless. Is he correct?

I pulled out the manual (dated 2005) that came with the stove and showed him where it stated as part of bi-annual mainetenance to put 2 drops of sae20 oil in the "oil" ports on the convection motor.

He told me he would find the proper answer but its been a few days and I figured I would probably get a quicker and more accurate answer from Hearth.com.

Regards,

Jon

Good luck hearing from that guy again. Probably didn't appreciate being told how to correctly do his job! Funny thing, instructions.

Anyway, not familiar with that model, but if you find oil ports in the motor like the manual says, use a couple of drops of motor oil. worked on my convection motor even though i don't have oil ports.

Posts some pictures of the motor showing the ports if you can. More knowledgeable members will respond.

Every envirofire convection blower I have seen was the oil type. Remove the blower, blow out with an air compressor, check the label (with say oil every 6 months or oilless) 2 oil channels on the motor lead to the bearings at the center. Should be pretty easy to locate.

Hello

I did some research on this and A.O. Smith the manufacturer of many of these stove blowers recommends motor oil on their motor bearings and shafts for lubrication at least once a year for longevity. Most convection motors have oil ports and some have rubber plugs to remove first. Also some not all exhaust blowers have oil ports also. SAE 20 also called 3-1 oil in the blue can works well. I just got the best product for this job. It is called Lubit-8 made by Tuf Oil with a patented Moly-PTFE formula.

nope, the new ones have sealed bearings, your tech was right

iirc, these are fasco's

What does the plate on the motor say all other information is meaningless. The motor in the stove rules.

stoves with a the tangential blowers M55, Empress, Mini, Maxx, Omega and EF5 need no oil and the squirrel cage blowers that come with the newer models, post 2010 don't need oil either....all EF2's would have oil ports.

Not always so.
I purchased 3 Fasco generic replacement combustion blowers. They do have the black rubber oil plugs! See Yellow arrow.

Many servicemen and techies prefer the blowers that can be lubricated evey year. According to the A.O. Smith small moter specifications Motor oil is the only recommended lubrication. Specifically SAE-20 or 3-1 oil or the new improved TufOil or the very Latest Tuf-Oil Lubit-8. With proper lubrication these motors generally will last much longer than the sealed bearing motors.

Wow....where the heck did you find out about that stuff???

I know there are oil holes in the case of the motor, I put oil in them last year. The Tech mentioned not to do that even though the holes are there the bearings are still oiless. Due to cost the manufacturer did not change the case.

I can understand the confusion here. The holes are above the motor shaft and the oil goes on the motor shaft. I lubricate the shaft of the motors even if there are no holes. According the specifications that A. O. Smith provide, they still recommend oil on the shafts and at the end of the motors. Sometimes there is a plastic cap on the end that can easily be removed. If this is done once a year, these motors will last longer. Some dealers may not do this so they can sell more motors. I am just providing the facts.
