Hello there,
before I get started may I first thank all who contributed to my last thread about my sticking clutch as after a strip down, plates boil (plewsy style) and careful setting up it is now snicking into gear in the morning with no problems at all, although the cols weather and salty roads have put paid to riding for 3 or so months!

So I have started to draw up the list of winter jobs! Most of them are fairly trivial cosmetic stuff. I have one engine job to complete (take of the exhaust rocker box and helicoil one of the outer 1/4 unc threads) but I am also contemplating replacing the crank feed oil seal in the timing cover. My bike shows no signs of low oil pressure, the only reason I am possibly going to do this is as the bike is fairly new to me (9 months) I don't know it's condition/age.

So.......It ain't broke! But should I fix it?

My rational is,
1. If it does fail, big damage may occur.
2. It is cheap and easy to do.
3. Peace of mind once done.

Am I mad?

No - but you might be later.

You might as well replace the contact breaker seal while your at it.

Then you will have to re-assemble the c/b assembly and re-time the engine.

Make sure all is well before disassembly and mark the points backing plate (index it) to aid reassembly.

There's more chance of a new seal failing in the first 5 minutes,than there is of the old seal failing in the next 5 or 15 years.
Some seals won't stand the pressure,and become inverted (instant loss of oil pressure).

You want peace of mind?

Temporarily fit an oil pressure gauge, then go for a 20 mile ride. If pressure remains normal, remove the gauge and stop worrying.

From what I can tell the crank seal is reliable so probably best just to leave alone. I do have a gauge I can fit, just for the record what kind of pressures should I be expecting?

I'd go by what's in the book.

I have composed the proper corollary statement to the age-old axiom "If it ain't broke..."

It is... "fix it 'till you are."

very true!!
