|OIL And Lubrication|
“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.
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 !
