There are many pitfalls with developing a new coupling for the M3W and, for me, the biggest drawback is the need to remove the engine every time for inspection / modification.
I agree that experiments with such as the Lovejoy unit are worthwhile as would be the development of something new - which I have considered.
However, my work has involved many changes to the rubbers to avoid - early failure - high temperature failure - failure due to material spec. ( which can be variable!) - bouncing ( which causes gear hammer ) -and a strange unidentifiable bump in the night which came and went sporadically with one shape. Add to this the possibility of the splines in the centa coupling failing - which is becoming more common and you have more reasons than enough to take the engine out.
I had the engine out of mine 7 times before adapting for quick change of the rubbers which now takes half an hour and I have probably done 20 different experiments since the quick change idea.
Anyone installing a unit which can't be changed out frequently and quickly, without too much workshop time, runs the risk of not being able to put enough time in to trouble shooting - It has taken me years.
Anyway, I have great respect for the Krazy Horse team and I am sure they will give it their best shot but don't be too hard on them if it takes time - this job is bloody near impossible. I will contact them outside of these pages to offer any insight that I can give. if they get it right early on it will be a godsend to us all.
