Cubman

Don’t use any engine oil besides the recommended cub utv/atv engine oil, it’s a cub cadet product with special synthetics. The tensioner operates with a spring, remove the tensioner, there’s a cap screw on top, once cap screw is removed you can use a small flathead to test spring rebound. The tensioner should measure out to 58 nm fully extended. These should be checked regularly. Not the greatest thing to have to do but I hope it helps.
