Talk Morgan Forums Morgan Sports Cars Maintenance & Servicing Metric system

Hello

Is the Morgan factory use the metric system like in Europe?
Thank you

My Plus Four 2023 model has a mix. The thread for the luggage rack bolt is not metric. I think it is UNF as I used a tap to clean it up. No idea what else uses metric/ imperial yet No doubt I'll discover that when the time comes!

Very unspecific question, certainly depends on the age of car & part

Depends .....

Since the 1930's Morgans have used a mix of Whitworth, Imperial and metric....

Plus whatever else prevous owners have fitted

Or incorrectly forced in

I'm pretty sure there was some British Standard Pipe Thread on my oil pressure take off.

On my previous, a 2002 Plus8, whenever I did a job I considered renewing fasteners. One example was removing the seats. The rear bolts on the runners were standard hex head. This head sat inside a channel so no room for a spanner or socket. Rather than wedge a screwdriver to lock it I used a small stilson type tool that fitted and held in with tape while undoing the nut. I replaced the bolts with socket heads and used a matched socket instead of a spanner/ hex socket/stilson.The front bolts left as they were as they had easy access.
To help try and ID threads I have a thread gauge and a stock of nuts as testers, kept in small labelled plastic bags. Spanner size? I have sets of metric/imperial/whitworth etc plus some odds and sods rescued from scrap for modifying for specific jobs.

Having rebuilt my series Land Rover over the years I have a bin for imperial stainless (mainly UNF) plus one for metric fittings and a third for washers of various types. The former nicely covers most of the body/chassis/suspension fittings on my Roadster. I keep each bin topped up as I run out of any particular nut, popular length bolt or washer so I can be assured when needed the correct ones are there. For the most part except in critical load situations old fittings get replaced with stainless after dismantling as I hate to see rusty ones.

I've found over the 21 years of Morganing my set of BA nut spinners and and open enders come in handy too for the smaller stuff..

A good selection of Metric, Whitworth normally suffices.

An angle grinder for the exhaust has been known to be used in extremis on the U clamps..
