hydraulic fan oil and filter

[Dan Williams]

I
tried to attach the exact numbers as a file but it didn’t work so here is
the narrative: COPPER AND LEAD APPEAR HIGH! ELEVATED COPPER MAY BE SOURCED TO
BUSHINGS, THRUST WASHERS, COPPER OXIDES, NON-MECHANICAL ORIGIN. ELEVATED LEAD
LEVELS ARE NOT

COMMONLY
ASSOCIATED WITH CRITICAL WEAR OF MOST HYDRAULIC COMPONENTS. LEAD COULD BE
SOURCED TO ORIGINAL/SUPPLEMENTAL ADDITIVES. VISCOSITY (V100 READING)

INDICATES
THIS IS 20 WEIGHT OR EQUIVALENT OIL. OTHER ANALYSIS READINGS APPEAR TO BE ACCEPTABLE. MORE SAMPLE
HISTORY NEEDED TO ESTABLISH A WEAR TREND.

Dan: Have you had the coach out on the road recently.
If oil is

brown on the bottom, then it sounds like it has been setting still and

some solids have settled. Please do inform me of the analysis.



I use a software to keep all my records. It is called Rolling Stock.

It was designed by a friend of mine and several fleets use it. Not

sure what it cost right now. I was a Beta Tester on it several years

back. If you are interested in it, I'll send you a URL to look at it.

It has a Reminders page to let you know when the next services are due.
