## Description

LiftMaster Idler Pulley 144C56

Review: Works as designed - An exact replacement for the idler pulley that had broken due to age (Original was over 15 years old). Installation is straight forward and easy with a couple of basic tools any handyman should own. The pulley is NOT intended to carry the weight of the garage door, as one reviewer implied. The pulley IS designed to guide the cable that is part of the drive chain that moves the trolley on the garage door opener. The weight of the garage door is solely carried by the springs and the door track.
Review: Good replacement part, but wanted a different solution - I bought this to replace the identical broken one on my brand new garage door opener. While the piece itself is fine, I wanted a longer term solution because judging on the reviews these just weren’t made to last for their intended purpose. My 5 star rating is based on the fact that this part is the actual replacement part. There is nothing wrong with it, it was just not built to last. The manufacturer should have made this a metal part to begin with. I purchased a different pulley made of different material that would hold up longer (2.5" Lifetime Pulley Nylon Sheave with .25 Inch ID Stainless Steel Bushing). I ended up using the other one and will keep this part in case that one breaks. I did have to purchase a 5/16” bolt, washer and nut to hold the pulley in place as the center diameter was smaller but so far so good. Just wanted to help some of you out who are having the same issues as me!

## Questions & Answers

**Q: has anyone found a comparable metal pulley for this piece of junk?**
A: Can confirm pully 5308010 from Ace Hardware works perfect. Pull out the pully from the sleeve and pop out the metal bushing in the middle to obtain the .5” bore. Toss the sleeve and bushing and you are ready to install. Runs about $11 at my Ace

**Q: What are the dimensions of this? Diameter, thickness front to back and diameter of hole?**
A: The bore is 1/2 inch, not 9/16, for use with 1/2 inch bolt. Diameter is approximately 2.5 inches. Wire/cable channel width is 1/8 to 3/16 inch. If your garage opener originally used this, other answers to other questions suggest it's possible to find a steel 2.5 inch idler pulley with the same 0.5 inch bore.

**Q: what's the ID and OD?**
A: Sorry, I don't understand the question ÎÒ²»Ã÷°   Wǒ bù míngbái nǐ de wèntí

**Q: R we seeing higher prices based on browsing habits, whats opinion of Ebay this part 2 for 11.25 with shipping.???**
A: There is a lot of confusing pricing out there.

### ⭐⭐⭐⭐⭐ 3rd pulley, I found that my installation was incorrect.
*by J***H on January 4, 2021*

I have two garage doors, both using the same openers. One opener is still running on the original plastic pulley, the other one just had its 3rd pulley installed. I found that the pulley failure is my fault. When I installed the openers, I had to add an addtional kit for use on 10' tall doors instead of the standard 8' door. When I inserted the 2 foot rail extender, I failed to bend up the physical stop on the one unit, but I did bend it up on the other unit. The stop prevents the trolley from going too far and hitting the plastic pulley, which when it hits in the winter, the trolley breaks my pulleys. If your rail does not have the prong bent up towards 12:00 (the prong is located about 4 inches from the pulley on the top of the rail) you can bend it out with a flat screwdriver. If you find that yours is lying flat with the rail surface, this may be why your pulley has broken. The other thing I changed, was I increased the angle of the arm that connects the trolley to the door. When the garage door was in the closed position, the angle of the connecting arm was straight up and down which allowed the trolley to move too close to the pulley. I removed the two bolts that secure the two halves of the connecting arm together, increased the length of the connecting arm by about 4 inches, bolted it back together and reprogrammed my up and down stops at the power unit. Everything is working very well now, and the trolley does not even come close to the pulley any longer.
