Mk1 Mazda MX5 Buyers guide part 2 - short nose crank engine

A look at how to spot the short nose crank engine and how to see if there is a problem with it

[@crawford323]

Thank you for showing the actual crank pulleys. Most books might mention 4 slots vs 8 slots on the pulley to identify the crank you have at a glance but few show an actual photograph. Even the official shop manual does not show photographs illustrating the differences. So good show!

[@carscameras3410]

Nice video mate. Keep them up :)

[@rafaelrjarquin]

Can you write in the description please what to check on that pulley, I'm French canadian and can't understand you accent really well. Thanks Future mk1 mx5 owner

I do have the 1.8l gtx turbo engine and do have shortnose crankshaft

[@UocLv]

If my timing is jumping at idle around ~1.5 degrees, is this is the issue? My pulley is solid chunk of rust. I think i just have do drive, and when it fails, swap an engine. It will be cheaper, these new MX5 parts are so expensive.

Evening, great video and exactly what I'm after. Hoping to finally pick up a mk1 in approx 3 months. can you recommend a trader that imports rust free examples? I've been to see 9 to date all described as mint and all turned out to be rot boxes.

+Glen Dunn hi glen, We don't import them, but we do get hold of good cars, we currently have a couple in stock, both need a little work though, where are you based?

[@princesstrojan740]

+Lights go up Lights go down The north of Scotland, close to Inverness. Willing to travel for the right car. do you have a website?

[@lightsuplightsdown3018]

+Glen Dunn we do, but we are based in East Sussex, so couldn't be further away really, the website is www.themx5restorer.co.uk There is a red car on the website, but that has sold, the other two we have are not on there yet because they aren't ready yet really

Wrong sir! The Loctite 660 fix will work for many miles.

[@xTheNameisEthan]

So if i have a 92’ with the original motor it has a long nose crank?

[@stefantenzer4363]

I guess

[@andrehenry3663]

my pully wobbles at idle. any idea what would cause that

[@bagelbytes69420]

Andre Henry bad keyway causes pulley wobble and timing to skip

[@tonyb76]

why not buy a new keyway?

[@lightsuplightsdown3018]

Because the key way is part of the crank, so therefore you would need to buy a new crank

[@BD5243]

Because it'a already worn.

[@costa_349]

The keyway is a groove in the crankshaft. And to replace the crankshaft you'd need to pull the engine apart,replacing a bunch of stuff that isn't re-usable (basically you'd be rebuilding an engine). And rebuilding an engine is expensive and time consuming, applying tread glue to a bolt isn't

My 1998 NB 1.6 died regardless lol
