Awry

You're correct, the Aero chassis is bonded. However it also uses rivets for braces!

Cheers

Cool. So all I need to do is take a set of stock pb bushes, chuck them up and take a couple of thou of the outer diameter, and bond them into the stub axle tubes using the kingpin to ensure alignment? Sounds much easier than faffing about with a reamer.

It's almost a shame I've got HC kingpins and only around 35k miles on them. It's going to be a while before they need doing.

I see according to My supplier "Team Tube" (Canadian) the C1045 Hard Chrome Rod comes in 3 Chrome thicknesses. .001, .002 & .005

In principle that’s pretty much it just don’t get any Loctite on the pins

I will report back (good or bad) when I have had a go at mine.


.005” That’s just OTT extravagant!

Yes please Rog, I'd be extremely interested to find out how you get on.

What grade Loctite would you use? 680?

"Loctite 609 will allow you to disassemble at a
future date, but even stronger types are available if
you don’t trust this medium strength product!"

Win is a retired insurance executive. I am sure this information came from the Machine Shop (friend) that did the job. This is Bearing Retainer Loctite.

I think there may be quite a few grades that could be contenders, certainly the ones mentioned. If the tubes haven’t been machined the bores may well be out of round so gap filling capability would be a consideration. Plan A for me is to follow the manufacturer’s instructions and use 648 with my Hilubes.

Loctite 648 looks good for Vesconite Hi-Lube other than "Rapid Cure". Certainly would want enough time to to get the bush in position and aligned and also grease seals in place. So I would look at "Rapid Cure" Directions carefully.

Not sure but I think Tim H. will use bronze and therefore I would use 680 unless somebody with more information and actual use on Loctite gave other advice.

Yes, boring the stub-axle tubes straight would be a sensible move. Not something I could do on my little Myford, but I have made friends with a couple of guys who run a small engineering shop specialising in one-offs/short runs for the aviation industry, and I'm sure I could persuade them to do it for me.

The whole Vesconite thing has got me conflicted a bit, to be honest. It's a great material no doubt, and for many the fact that it does not require lubrication would be extremely attractive, but for me personally it's actually a disadvantage in a way.

One of the main reasons I love my Morgan so much is that it demands a level of owner involvement much greater than a tin-top. The bi-monthly ritual of getting under the car, greasing the kingpins, checking the suspension and brakes, tightening up any fasteners, and generally fossicking about with the thing is a complete joy for me.

Aren't all Morgans held together largely by this stuff ?
