PPM

[charles_reed]

Those of you on the oilfields will know this acronym - Planned Preventative Maintenance.

It's based on having statistically significant records for your machinery and the various failure modes and acting to replace/repair before the probability of failure goes above the 10% level.

How about a quantitative report from all of us about the various parts of a boat - I'd rather change things just-in-time than wait until one has a failure at (if lucky) and inconvenient time (if unlucky) at a time of crisis.

In fact wouldn't that be a more valuable board than one on the price of fuel-oil?

<font color=blue>PPM should be done early, I kept putting off replacing my wife for a newer model and now its too late, nobody will take her off my hands... you should see her shambling along knuckles all torn and bruised from bare fist fighting, unshaven for days on end, half her teeth missing the other half stained from chewing tobacco and a great swarm of flies following her wherever she goes. </font color=blue>

I think it's a good idea, just like replacing you're impellors every year, I keep the old ones for one year as spares, if they are ok, then dump them the following year. Of course, flares are an excellent example!

<font color=blue> Even if Flares come back into fashion I couldn't wear my old ones anyway, I must have put on 10" on my waist since then. </font color=blue>

So when did flares go out off fashion i still wear mine but the turn ups are a pain for catching sparks when you are welding.

Drive Belts

In addition to the raw water impeller, I include Drive Belts in this category. I have two and I replace them both during my Autumn lay-up. They might last longer, but then again ... ... ... At £20 for the pair they are worth the price for the peace-of-mind.

I have a friend who replaces his engine control cables every year on the same principle. That seems OTT to me, but I would appreciate the opinion of others on that one. Mine have lasted 12 years so far. Maybe they are due for a change?

and a cross reference section

so that you dont have to pay £20 for a pair of belts, or £16 for a volvo oil filter, or £24 for a volvo water impellor when johnsons are £11.
come on PBO where are you? this subject has been broached before,

We stopped using PPM some years ago and now use RCM - Reliability Centred Maintenance - this is part of the gas industry.

The concept being if it ain't broke don't fix it!

Re: If it ain\'t broke

I follow this principle as well.
Check things often, repair or replace when there are signs of possible failure.
