Hey Mini Enthusiasts,
First of all, very glad to be part of this community, this is my first question/forum post.
1973 MkIII 850 Saloon
The car has done about 120.000km, and I suspect the elements in question are still the original ones. Bought the car from an elderly man (first owner) who had had it in a shed for 10 years plus. It's got new paint, sealed underbody, seats refurbed... a few nice bits added like petrol cap... New carpet (came with vinyl mats in its original state), Dynamo serviced, new regulator, brakes bled, new carb, new airfilter... anyhow... Currently in the state of renewing Knuckle Joints, Rubber cones, Dampers/Shocks and installing HI Los.
Just ripped out the old knuckle joints from the top arm yesterday, which was a bit of a pain. Blow torch came in very handy, hope the fumes of burnt plastic didn't cause too much damage to my braincells (I suspect not more than the garage beers ).
Anyhow, I noticed that the nylon cup on the front drivers side wore through in the bottom section, alas bare metal at the bottom.
So I cleaned and checked the top arm for wear and compared to the passenger side (nylon cup fully intact there). Whilst I have not been able to measure the difference yet, it seems that the driver side top arm is worn ever so slightly, i.e. the passenger side still shows visible stripes from the milling, whereas the driver side doesn't.
Visually it doesn't look terribly worn, i.e. rounded. Will try and post some pics tonight.
Anyhow did a bit of research on the web and found this article:
Where it is suggested to fill up the bottom of the joint with Aladite or similar epoxy, then insert the nylon cup. It seems plausible but not sure whether it is
a.) a good idea? (sceptical about enforcing metal with epoxy)
b.) necessary considering the very light wear (at least from my Judgement)?
c.) something where I could do greater damage, I.E. damage the top arm
I would like to avoid replacing the top arm, at least for now. I am aware that knuckle joints like to eat into the top arms, and that using worn top arms will result in increased wear on the top arm.
Any suggestions are welcome! Many thanks in advance.
By the way, I forgot to mention that the Trumpet had seized to the Knuckle joint so badly that I had to cut through the knuckle joint in order to remove the elements.
