I do NOT recommend using used torsion springs (EVER). When determining the correct torsion spring(s) that should be installed on a sectional door, there are several factors that should be considered: 1) the total closed door weight, 2) the door height, 3) type of cable drum and 4) type of door track lift. A trained professional (or a door manufacturer like www.amarr.com) can calculate and advise on the correct springs that should be installed on a sectional door. A few important points: At a minimum new torsion springs should last 10,000 cycles (that is up & down 10,000 times). This is a DASMA industry standard (i.e. all N. American Mfg are members of DASMA - allows the industry to set important consumer safety standards). Clearly, the life of a spring or set of springs will vary depending on the number of times the door cycles per day. The reason I caution against using "used" springs is because you cannot measure the remaining force (IPPT) of the springs. Thus, you do not know if the spring(s) will have enough force to properly balance the door or how long the springs will last. Formula for Calculating Torsion Springs: Total Door Weight X Drum Multiplier = In-Pounds per Turn (or IPPT) * the cable drum multiplier is varies based on the door height and type of cable drum Lets assume you have a door that requires a total IPPT of 50 and a door height of 7' tall. This means, the installer can use 1 spring that has an IPPT of 50 or 2 springs that have an IPPT of 25 = a total IPPT of 50, 3 springs, etc.... Over time, the IPPT or strength of each spring diminishes. Thus, eventually a spring will break over time. If you use a "used" spring - it is a matter of time before the spring or springs will break. When I train installers on the importance of using the correct torsion springs, I explain "its almost as if a mechanic tells you - you are going to need a new set of front brake pads and you reply by telling the mechanic - only change the front left today, the other side still works. NOT recommended at all. The easiest way to confirm if you door has the correct springs is to disconnect the garage door opener arm and manually open the door 1' or 2' off the ground. If the door stays in that position, the door is most likely properly balanced. If the door jumps off the floor or is heavy = you have the wrong springs. Good luck!

Amarr's Classica door model includes 15" radius standard. Other radius tracks are available upon request. Most residential doors in the US have 12" radius track, which is common when your door panels are 21" or 18" tall.

Sorry - I don't understand your question. To see why vise grips are used, start the video at 3:10. Helps maintain tension on your torsion cables while winding the spring(s).

How do I know that the spring sang?

@@khaledkhaled6181 i'm sorry but i do not understand your question. The springs provided by the garage door manufacturer should balance the door. The manufacturer can advise you the # of turns to put on each torsion springs.

? Im not with amar but install them everyday, dont really understand your question

+William Minton wasn't a question. the guy in the video installs the end bearing plates wrong. sorry you have to install that cheap crap.

lol, pays the bills, anything other then wayne dawton and im happy

+William Minton Wayne Dalton is only good when I get to take them down or lnstall spring conversions. the conversions are a money maker.

i agree, i wont even take a idrive down unless they agree to spring conversion, lol

Sorry - I am unfamiliar with toyhauler ramp doors.

Another Tip - If you have 1 torsion spring, observe the direction that the spring wire near the spring cone that you are winding. That wire should ALWAYS be facing upwards towards the ceiling, which means once you affix the stationary cone to the bearing plate, you should be winding the springs in an upward direction.

The winding device is only included with DIY retail door sales. If you did not receive a copy of the winding device instructions, please request a copy by emailing: ASCTechSupport.amarr.us@entrematic.com

@@DavidReedAmarr it would be really useful if you could make an updated video to reflect the S3 winder the factory is shipping with their products.
