Do a google search of "Liftmaster 8500 manual" and look at page 3 for all the pre-installation requirements. I found this link: http://www.liftmaster.com/CatalogResourcesV3/en-us/shared/files/tucmanuals/114A4565.pdf On that page it gives this answer: The torsion bar must extend at least 1-5 inches (2.5-12 cm) past the bearing plate. This may vary depending on your installation requirements.

It's been awhile since I installed mine, but remember the steps you take to disassemble and do it in reverse to install. Check on line with Liftmaster, they may have it. Good Luck.

I would suggest to check compatability with the Liftmaster website using your equipment model number. This is how I found out about mine, to see if it is going to work.

This product is excellent and very easy to install.It's universal so should work with Lift Master.

I expect your model # may work. As I understand the letter designation, A, B, C, D, etc were model updates but the gear assembly you refer to were the same throughout all the models. The number you listed is a logic board #. The gear and sprocket assembly complete is 41C220A. Chamberlain Customer Support number, 1-800-528-5880, as a good resource, I've used them, they are good.

Hey Kerri, What I did was look up the manufacture and get a chart that shows all of the size combinations.You need to know the length of the strut fully opened and fully closed and about how much it needs to lift. there are dealers on ebay that sell these. Do you have any info on the old struts? is this the p/n Lift-O-Mat FMR114 0140N 299/93. Google search it helps. email me Randy 1bad62baja@sbcglobal.net

Hi Kalju, I watched the you tube installation videos and eyeballed the parts for fit.I think the two plastic gears are standard across most opener models.Also, since the parts are so cheap, you may want to order several kits to be sure you get the right parts.You can also sane spares for later repairs.

I suggest you go to the website for the "air Lift Units". They want your truck info and then they will tell you what you need to know. You can contact them via email as well I am sure... to help with your specific question. Jim

You can call their toll free number and speak to one of the reps who actually know their stuff and ask the question. Sorry I couldn't be of more help.

Hello Denny,Could not research by that model # but was able to research by 917.276180...maybe there was a typo with the first number?If so the kit you have referenced will not work with this unit.The spindle assembly this model # calls for is a four mounting hole spindle part #187292We, unfortunately, do not stock a kit with a four mounting hole spindle.The blades part #139775.The belt part #197253.The pulley part #197473.Hope this helps.AMC Parts Store

Thanks for the info. It looks like everything matches for part numbers except the pulleys.

I would just call Skyjacker. They are really knowledgeable. They gave me me all the part numbers for all the components I needed for a lift kit and then I turned around and bought it all from Amazon.

I suggest contacting the tool truck operators (Snap-on, Mac or Matco) in your area to see if they can help you. If they carry or can supply Gearwrench tools they should be able to warranty the part you need.
