I have a simplex kit, which the cam gear is NOS with 2 tensioners rubber rings. When I fit a new minispares chain in it it does not settle properly, I mean, only some teeth are ok then starts to feel pressure that makes them pop-out. If I use my old gear from the car happens quite the same. Does this happen to any of you? My old chain+old wheel settle nicely together.
For 850 engine, what are you people using when using simplex cam/crank gears? As they seem to not be no longer available cam gear with tensioners rings. I bought a kit from minispares but they just have 2 gears and a chain, no tensioners!
Thank you, Spider ! Probably it can explains the issue.
Should I use the minispares simplex kit, which does not have rubber bands on the cam wheel ? So, will be without any tensioners (tension-less), as it is a 850 engine, not later type with the tensioner apart.
As I was not happy the the issue, I am also considering in swaping for duplex chain, even if too much for this 850 STD engine.
The original simplex set-up was famous for rattling noises and new rubber tensioners did not last very long before rattling again.
I had the standard simplex set on my 1100 mini then changed to the duplex set-up (like the Cooper S). It was much quieter even without any tensioner.
There are 2 hex headed screws under the crankshaft gear that have to be changed to countersunk headed screws for clearance if you change to duplex.
