Laurens, I imagine the mountain driving is hard on the heating on the belt.
S&s have recommended a 3000 mile interval betqeen cam belt changes.
I am worried about an open air/washer solution due to rust on the weak and vulnerable cam shaft and sprocket interface.
Here is an exceprt from an email between me and malvern hq, it was on a wide range of issues but here is on the cam belt:
6. Cam belt
It has become clear to some owners that the timing/cam belt needs to be replaced at least every 7000 miles. This is below the recommended interval.
6.1) WHY DO YOU CHARGE SUCH A HIGH PRICE FOR A NEW CAM BELT? Your price is well in excess of S&S dealers. This is especially unacceptable when your recommended replacement interval was far too optimistic at the time of vehicle purchase.
We have a pricing formula that is applied to all components based on our purchase price, this formula does not result in Morgan 3 Wheeler achieving higher margins, however now you have raised this I will ask our Parts department to investigate your concern.
6.2) What investigations are you conducting with S&S and Gates to find a more appropriate Cam belt for the high tension system early vehicles?
S&S and Gates have completed testing in this area, as recommended we follow their installation and service for any replacement parts. On early models the cam belt was over heating due to the lack of air circulation, by spacing out the cam belt cover this resolved the issue. This was the solution from S&S after they carried out extensive testing in this area.
7.Cam Shaft and timing belt sprocket interface
The S&S cam shaft and sprocket interface is not fit for purpose. This results in the timing belt sprocket coming loose on some vehicles and shortly after a failure results. Owners have to check every couple thousand miles for looseness and play in the cam belt.
7.1) What investigations are you conducting with S&S in order to get the cam shaft and sprocket interface lengthened/ uprated?
S& S are currently investigating this issue,
