A warning about a dodgy practice now being done on the crank boss

Postby Mazda Mender » Wed Nov 04, 2020 8:29 am


Over the last 12 months I have had 3 different mx/roadsters come to me for water pump,belts,seals and service wanting doing and on strip down found the crank boss's with a chuck missing at the top of travel ,dead top, when I seen the first one it was a case of ...whooops I wonder who messed that up and hid it, and replaced , second one was a case of ...that's strange,but replaced again.... By the third one, the alarm bells were ringing that this was becoming a common thing to find as a short cut to just changing a timing belt and "NOTHING ELSE".
Then yesterday a post popped up on a FB group of the same thing that had been found , an Owner had taken his Mazda to a garage for work and they had found the boss had been cut at the top the same as I have found the 3 I had come across. The only difference being that in his case and the ones I have found is that I informed the owners and "told " them it needs changing and its staying until it does. The garage this owner used just informed him and put it all back together with the crank seal clearly weeping oil out everywhere so it was a waste of time and money any way.

So i personally felt that this now warrants a warning, I am unsure how you would know after the work is done of this dodgy bodge as the crank pulley bolts to the boss hiding this lazy expensive c*ck up and beggars belief and is happening to the MK 1's from 1989 to the MK 2.5 to 2005.

Unfortunately I never took pics of the first two that were clearly cut, only the third from Austin's MK 1 and the pic from Stef Wrobel from the FB group to show. I'll be keeping an eye on this and take more pics of this happening. It is bad practice to take this route and short cut for a number of reasons, they are cutting this so they do not need to undo the crank bolt and not replacing the crank seals that also need replacing. So the work is all pointless as the oil is going to contaminate the new belt etc any way , so it will all need replacing "IF" they have not damaged the engine by now????

This is now starting to look like becoming common place and the f*ckwit that started this wants hitting with a scaffolding pole hard because the sheep in the community are following it and doing it also as a correct short cut. Cutting that boss makes it all unbalanced which in turn "WILL" damage the crank shaft, seal, pulley, pistons as it starts to cause everything to wear and become oval, it is lazy and costly for the owners. Its very bad practice, its just so bad.... If you find that this as been done then the boss need replacing asap, as does the crank seal and the cam seals will be in the same condition...

I would love to know where and how this as started to be passed along to other brain dead owners to follow and use this method or garage?

MK 1 boss is £60 + vat

So ,PLEASE,PLEASE,PLEASE take them to the correct people for work, rather than these idiots, that will cladly take your hard earn with a smile knowing that they have not done all the work that was needed and c*cked it up to get you to spend even more than in the first place to rectify it all from killing your engine .
