Never! let it be said im not up for a challenge.
Having answered Simons call for a bit of help, I decided to offer my limited
experience and took on the task of fixing the very small, and easily fixed, problem of a sheared off timing chain tensioner bolt removal.
What a Cnut
of a job it turned out to be (understatement).
I've done one or two (not hundreds as some posters on this forum may state) types of jobs in the past. This one was a different prospect. The broken ezy out was not able to be removed (long story there) and I tried everything from drilling out the outer circumference of the bolt with wire drills (1mm and smaller) to attempting to weld a nut to the end of the broken bolt/ezy out and removing the obstruction that way.
Following the failure of this, I drilled an oversize hole in the block and tensioner and then machined up a plug which, with a tolerance fit, would I thought hopefully solve the problem (wrong) coupled with some of Mr Loctites finest.
To cut a long, long story very short, I ended up tapping the block with a metric 9 * 1.25 tap and machining up another plug to screw into the block (albeit, due to the broken ezy out, only about two turns). The opposite end of the tap has a metric 6mm thread tapped into it to take a (shortened) bolt to hold the tensioner block in place.
I'm 99.5% sure it willwork like a charm
Back to fixing the wagon
