Lubrication

 Vacuum-Blowers..

“Down the throat” of the blower..   WD40 is an OK penetrant,

and an OK moisture-barrier,  But Diesel fuel is just as good a barrier,

maybe even better, as it might not evaporate as fast.     ..and it’s much cheaper.

If the system is stored for more than 4 days between uses,

you may want to go to a better protective coating..

Like  WW Grainger’s   #4JB29 is a CRC product #3-36  spray-coating,

rated  to 250 degrees, and cheap.. $7.00 per 16 oz. can.

Before the blowers are mounted onto our systems, we treat them with “Dry Moly”.. 

WWG # 2F138 at $8.95 per can.

This puts down a  longer-lasting  coating,

which is “chemically attracted”  into the pores of the bare metal.. 

Good stuff !  ..in fact,  it is the VERY best lubricant you can use,

as a metal coating,  especially for blowers, and roller-chains.

At the pulley-end of the blower..

Squirt trailer-axle (“EP”) grease in the zerk-fittings (both) once each month.

As for the  oil-bath  in the Blower..

At “desert temperatures”..

 Use ISO-150 hydraulic oil..   like  WW Grainger  # 2EPU7 quarts at  $15.75

Or better yet, a synthetic version..

…  by AmsOil..   Synthetic Compressor oil   ISO-150   at $17.95 per Qt.

Otherwise,   in  20 to 90 degree F.  weather..

Use  “Universal Tractor-Transmission Oil..     API  # GL4

ISO100,  or  SAE 30wt  “Hydraulic oil”  (NON-detergent !)

… like  WW Grainger  # 6Y782   DTE Extra-Heavy lube..  1 gallon   $ 27.95

… or    WW Grainger  # 1MUC7  XP-150 gear-oil ..    1 gallon  $ 27.95  

… or   WW Grainger  # 1MDJ8    Industrial pump oil..    1 pint   $13.95

Even better..  use a Synthetic version..

… by AmsOil..  Synthetic Compressor oil ISO-100   at  $17.95 per Qt.

Water Pumps..

Use ISO 100, as above, for all temperatures

Synthetic is HIGHLY recommended at higher temps.

Small single & V-twin Motors..     require   30wt HD motor oil,

or  synthetic  10-30wt   ..like AmsOil  !
