Re: new in p.a. & hello
Replace all the china hardware on the tentioner ,with nuts and bolts made in usa.
Position on rail,closer to rear sprocket is best for adjustment ,make sure to tighten very tight. Check to see if the roller is line with chain,if not place adjustable below roller and bend for correct alignment , test ride . make sure it works smoothly . if so drill and tap tentioner and rail, use center punch so drill will not walk. with 10-36 bolt . this worked for me
