How to Choose a Socket for Rachet?

british made? Less than 30 years old?

Probably at least 25 years old Briggs & Stratton SPP175.

Buy an adjustable wrench. Fits metric and imperial.

There's only access for a socket directly above due to 'housing'.

I have to say it looks more like 15/16" than 14mm but it's really hard to be sure...

15/16” is about 23mm so quite an obvious difference from 14mm

It is. 24mm Vs 15/16"

OK, one of those multi sockets with pins that fit a range of nut sizes

 

[Mottie]

I’m getting confused. You’ve mentioned 14mm, 18mm, 24mm and 15/16”. You Best Buy a set of sockets that covers all those sizes.

 

[Foresty Forest]

Its 15/16" as best I can tell with my ruler and slightly dodgy eyesight.

Probably at least 25 years old Briggs & Stratton SPP175.

Made in a primitive country, is likely to use UNC threads and AF Inch Size spanners.

Unless you like old cars and tractors or American machinery, you are unlikely to have much use for a set. But there are plenty available in estate sales on ebay from the sheds of elderly gentlemen.

Here is a map of the world showing the countries that do not officially use the SI (metric system)

Are you able to lock the shaft that this nut and sprocket are attached to?

Good point - looks like I'd have to hold either the cog or the scarifier 'arms' manually to provide resistance. Ideally I'd find a replacement cog, which I can't so far - But the plan is to remove this one from the scarifier and use it for the blades (cog broken). Scarifier and blades are interchangeable - slide in and out.

 

[Burnerman]

Yes, I thought so so care needed there!
I don't suppose you know anyone with an impact wrench that you can use to shock the nut free?

Yes, Metric is for the "thick" Europeans who find multiplying or dividing by anything other than 10 impossible to comprehend.

8'x4'x18mm plaster board anyone? (ok, I know it's really 2400x1200x18mm) but it amuses me in a childish way.

Same reason chucks are often 13mm. As it rounded up 0.5"

UK and metric is odd. I use solely metric for measuring most things. Apart from miles, speed, height and weight and alcoholic drinks, unless it's spirits when it's back to metric.

Can you post a picture of the cog and said nut on the machine, not too close in
