Or rather than doing that time consuming effort of a job, just see what revs your doing at 60 in 4th , and plonk the data + wheel size into the guessworks calculator, the modern and easier way.. 

 

Speedo drive gears failing? lol another scaremongering post from the usual. 

[tiger99]

Speedo drive gears can and do fail, and it is not scaremongering to identify that possibility. It is not very common, and I never suggested that it was. It is usually caused by a stiff speedo cable due to a kink or lack of lubrication. But if it happens, it is a very good idea to know the gear ratio in advance, because the car is going to be out of action for several hours once the correct replacement parts arrive, but a lot longer if you have to strip it first to find out what ratio you need. And contrary to popular belief it is not an engine out job to change both drive gears.

Only idiots imagine that nothing ever breaks. The fact is that anything can fail, and many things can fail suddenly, without warning. People die because fools ignore that fact, and place reliance on something that is, at best, bad engineering. Identifying those situations so they can be avoided is not scaremongering, it is just proper engineering practice. The reason that most modern things are relatively safe is that all possible failure modes are considered at the design stage, and mitigated. Fools blindly add extra critical failure modes and will never be told that what they are doing is wrong and often illegal.

But if you want to play the fool, go and overtighten your ball joints to stop them knocking and see how fast you can drive up and down some steep, twisty roads with precipices. It might even be a good form of population control as it will selectively weed out idiots.

Who mentionned balljoints?
I wonder why you Have No warning points. Systematically calling people idiots doesn't help.(not that I disagree,but there are many better ways of trying to prove a point and teach something.) I would strongly advice to clean the gearbox case and inspect everything when the speedo drive gear goes. Have seen it on a rally car and wasn't pretty.
Sorry @ OP to go off topic.:)

Wow, safe to say I'm with Dusky on this.

I'm all for safe practice and educating people for the better, but there are better ways to get your point across
