KOV 2.5 petrol manual estate
Very occasionally when I turn the key the starter whirs but does not crank the engine. It used to be once a week, now it's once every 10 starts. I fear the cure is to change the starter, and it needs doing soon.

I suspect you're probably right

[Bigron]

WD 40 now do an aerosol of PTFE-loaded lubricant. Try a good squirt of that on the relevant moving parts. Magic happens!

I was going to say WD-40 Silicone spray. I is the PTFE stuff better?

[Bigron]

The PTFE (teflon) version is true magic, yes. If the engagement pinion is sticking on the shaft, this stuff will clean the sh1t from it and leave a very low-friction PTFE coating which is electrically non-conductive, so no harm done if you overspray onto the starter motor electrics.

Thanks for explaining it Ron. Just ordered some.

Glad to be able to help. I got mine from Wickes, can't remember the price, but there is also another PTFE spray that I got from a boot sale years ago (no maker, sorry, as I used it all and dumped the empty can), which contained a totally dry PTFE powder for where solvents are inapproproate. My best use was on the plastic runners that my double-glazed windows slide on; they run as smooth as silk and no nasty oil to collect sticky debris in the channel!
My difficulty?
As I said, I don't recall who made it, to buy more.....

I'll give it ago on my sons cars electric window rubber sliders. His windows are getting very sluggish.

[TheBoy]

I lube the Omega window runners with similar, along with rear blind

Same shite that you use on plastic curtain rails etc, if you have a good local old fashion hardware store

[Bigron]

Thanks, TB. We DO have one such old-fashioned shop in our high street, they sell almost everything. However, I fear to enter usually because it must be run by Auntie Wainright, judging by the prices!

I tried mine with wd-40 Silicone spray. Never made much difference to my slow windows. I will try the PTFE spray next.

Last time I went to my local Ironmongers they said, best to rub a candle along it to wax it up.  Never did work very well. 

[Bigron]

May I add a caveat if anyone intends to spray this or any PTFE-laden product near hot engine parts, especially exhaust parts, as when exposed to temperatures above around 300 degrees centigrade it breaks down and produces toxic fumes.

Ron.

[terry paget]

Thanks for the idea gentlemen. I have found a spare starter in my parts heap, and realise that the only way I could spray anything on the pinion engagagement machinery involves removing either the starter or the gearbox. So I guess I have to change the starter.

[Ever Ready]

Might be a plan to give the replacement starter a good spray of PTFE before fitting it.
