Gday` new to the forum.
I have an old Rover Rancher 2 a RED one. The belt`s where a bit past there date.
So I replaced the B76 and B58 belt`s last week, she was working ok. yesterday I replaced A870/A33 drive belt on her And now when I put her in to gear she will not stop moving even with the brake on or go out of gear till the engine has stopped?. Is there a manual on these old Rover`s?
