I will keep working on the tensioners aswell Kev, hopfully we can help eachother
Nice idea to make solid adjustment, have to try that, thank's.
Ah yes, that remindes me that I took the orginal idler axels and made them a bit shorter and I'm not using the axel wich came with the tensioners. It proved to be to short. I'm using steel roadwheels. Not sure wht's causing my tracks to jump, but probably not all roadwheels are in a line or the idler wheel is still a bit off.
James, good thinking with shims. I shall keep that in mind.
