#1 Waterpump drive belt tension

Post by JerryL770 » Thu Jun 10, 2021 11:21 am

Is this adjustable of managed by the spring loaded pulley.

My belt seems rather loose. Does this mean it is too long, or can I adjust the tensioner to tighten it?

Advice appreciated, thanks.

Sorted. My 790mm belt had stretched to 800mm. Tried 3 factors for a 790 belt but no luck, only offered 800 ones. But . . .

. . . I've managed to procure a 785 belt which I'm anticipating is going to be a struggle to get on, nothing a bit of brute force cannot achieve, I hope.

Hoping that one will last a bit longer than the last which hasn't done more than 6000 mile. I wondered why my battery seemed to be lacking full charge.
