Some much needed good news!

Thanks to the poplularity of these VC refurbs (over 40 completed to date) I have been meaning to send Cancer Research a decent sized donation for a little while, but a pm from Jenny got me thinking that there must be a more tax-efficient way to do it i.e. making use of Gift Aid and my accounts not getting messy.

The VC that I do for Aidan are always paid direct by his customers, so the simple way was obvious: do the next few VC wholly for the charity, to restore the balance of honour and they get the gravy too.

I am pleased to say that the first one (that also needed a core 'cos it was completely destroyed) has just been shipped and Cancer Research received a donation of £400 :D

Well done everyone :ok

So if you have been putting the job off, now is the time to do something extra special for the cause.

I can't take all the credit, without the international negotiating efforts of the Kent Collective and the kindness of Our Man in Austria this would never have happened.

PS this project has actually raised over £2000 by way of the costed-in donations of £50 per VC, so get your VC's pulled asap and the t@x m@n :wink: won't get a look-in either. For a limited time only!

Just a quick post to remind people to attend to those tight or "aggressive" VC's before they do more unseen damage to the rest of the syncro drivetrain.
I have had a couple arrive with incredibly worn splines; one at the casing and the other was razor-sharp inside the hollow spindle (this one was also pitted so I suspect water ingress to the diff)
One of these was also basically empty, so it was just churning oily slurry inside. Not pretty.
I try to use the best parts that I have to hand but this stuff is fast disappearing, you can't just fit a fresh VC to a front diff with worn splines on the pinion shaft, they will just wear each other out again.
If you make a habit of going wading, think like a Land Rover owner and drain the diff and transaxle oils to check for water as soon as you can (this doesn't mean weeks or months later!)

Had a bit of a "lightbulb" moment when doing a couple of VC back-to-back on Friday.
Sometimes the end cover on these can have a noticeable dish when they have been driven to death while tight, due to repeated or prolonged excessive temp/pressure cycling.
Sometimes the casing is stretched at the big circlip too, giving the case a distinctive "flare"
All I can do is swap the end cover for a much flatter one, but this does mean that the internal volume of the VC is increased, if only by a couple of cc...this will affect its performance and change the hump temperature slightly.
Which explains why my theoretical fill weights appear to give a slight variation in VC performance, as proven by some covert testing recently ;)
The variation is subtle, it would seem that they are within the torque/temp tolerance band and for production purposes I reckon they wouldnt have been much different.
A pic of the worst one to date, I normally let a small dish (around 0.15mm at the minor diameter) pass.
All of which shows that as more abused stuff resurfaces, the need for lab testing and fill adjustment will become more important.
More on that project later.Image
