Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Torque for king pin bolt

Cain has just confirmed to me that the flanged bolts he supplied to me are 1/2" UNF and should fit in place of the original bolts

Thanks for confirming that Ray. So it means his flanged kingpin bolts, as shown in my post above following fitting hard chrome kingpins, are now available to fit the OE stainless ones as well. Note the latter typically need replacing around 25,000 miles though.

I've fitted the nearside kingpin bolt with the brake reaction stay- no problem with Cains flanged bolt, it is the correct thread to replace the OEM bolts.
Now got to drill the chassis for the other end of the stay. I will try and use the cardboard as was suggested in the Utube video.
However I did have problems removing the big wheel spinner/nut on both sides. They were so tight I needed a 5 foot piece of scaffolding to get enough leverage on the nut spanner.
.Surely they don't need to be that tight? I could not have done it on the road with a puncture. I know that the dealer skimmed the brake discs before I took delivery a couple of weeks ago, so they must have put the nuts on that tight perhaps with an air tool.

They can tighten with time. You can also in extemis pour hot water on the nut to help

A 600m breaker bar is more than adequate to tighten and release centre lock nut be it hex or spinner and assuming you have matching tool to engage with a socket - or at least it should be

Yes the centre lock nuts/spinners tighten in use, that's why they are handed per side so rather than undo on one side they will tighten. I too have had your experience in my early ownership days but luckily remembered my father telling me about this phenomenon. I have the octagonal socket to make life easy but regularly loosen and retighten the centre locks to prevent 0ver tightening happening. My father showed me this design feature by just literally snecking the spinners up and after a days driving they were adequately fastened for normal use. A safety feature in days gone by but with the higher torqued cars now, they tend to over tighten.

Spoked wheels, just as an aside can now be too flexible with higher torque vehicles. First they had increased the spoke count but now tend to use alloys as first seen for this reason in the roadster V6 although buyers sometimes still opted for them instead. and we are not seeing any classic spoked wheels now on current Morgans or centre locks.
