The All New Weaver W-PL240 Power Assist Arm is the easy way to change today's tough/stiff low profile and run flat tires.  

The W-PL240 system uses a powerful pneumatic cylinder to press or lift the tire beads into place taking the effort out of changing the toughest tires while keeping the process a one-man job.  The W-PL240 bolts onto the top of the existing tower on our W-894XS or W-898XS Weaver Tire Changers manufactured from mid 2018 and newer (tire changer sold separately).  Adding a W-PL240 to your Weaver Tire Changer provides effortless mounting and demounting of stubborn low profile and/or run flat style tires.  

Use the 2 included roller arms or the lifting disc to simply press or pull the bead into the drop center and roll the tire on or off.  The easy to operate up/down lever raises up or pushes down the tire bead into the drop center to allow changing the most difficult tires.  The main cylinder is equipped with a bead pressing cone for pushing the bead into place or use the roller arms, your choice.  The W-PL240 is also equipped with a lifting disc for raising the lower bead into the proper position as needed. 

The W-PL240 Assist Arm takes the effort out of changing tough sidewall tires at a very affordable price.  Add one to your changer and save your efforts for more meaningful tasks.

Fits Weaver XS models and newer.  Older XS models may require a Collar Kit or Tower at an additional expense.  

Max Force pressure is 400KG at 8 bar air supply. 

Shipping Weight is 100 lbs. (Reduced weight system by utilizing the existing column to support the Assist Arm)

    This is the 8 month up date. The assist arm is used on all the tires I mount and continues to make tire work much easier for an old man!

    Power Assist arm

    Posted by George B Lenart on 12th Jan 2021

    Once the install was complete on the tire Machine (non Weaver) the unit will be very helpful in changing all sorts of tires. Very well made and does not take up extra space in very small shop.

    A necessary attachment

    Posted by AR Service on 4th Sep 2020

    I bought this attachment to hopefully be able to dismount my wifes run flat tires. I finally had a reason to give it a try when i had to remove her tire sensor. The power assist arm worked flawlessly. It was such a joy to use. If you already have a Weaver machine, or are looking to buy one, GET THIS ATTACHMENT WITH IT!! Totally satisfied customer. 10/10.

    Great Addition to Tire Changer

    Posted by J Kemp on 12th Mar 2020

    Installed easily on my Derek Weaver tire changer. The online video with the installation steps was excellent. I mounted a set of low profile tires -- piece of cake! The assist arm looks to be very robust and made from top-quality materials. I use this in my residential garage for personal use, so it'll likely never wear out. Derek Weaver shipped it out fast, too!

    This thing is great! No more using multiple tire spoons worked really good mounting a set of skidloader tires!

    A must for large diameter low profile summer performance tires like Bridgestone Potenza 245 x 40 x 19! Been stuck without it.

    Outstanding Tire Mount/Dismount Pneumatic Arm

    Posted by Alan Waller on 23rd Apr 2018

    I have a non-Weaver brand tire changer that I modified to fit this arm (welded 4 nuts to the top of the air tank post). I also had to remove 4” from the Weaver tube steel arm and reweld so it would center on my machine. I love the way this product works. It is very well engineered and makes changing tires a snap. Before I had to muscle the tires on and off but this addition takes almost all the work outfoxed the job. I would recommend this product which I feel is priced reasonably.

    W-PL240 Hydraulic Assist

    Posted by chris valero on 14th Sep 2017

    Had to update my tire machine to use this product. With the help of Derek, we purchased a new bead blast tower to accept the PL240. Very well built and not to difficult to install. This will make all future tire changes much easier. Highly recommend! Special thank you to Derek and his staff for helping get this setup.

    A must for low profile

    Posted by David on 29th Jul 2017

    Works great for low profile. Fit on my 894 with some easy mods. Helps with regular tires also. Needed help from tech on how to operate. Tech is awesome!

    Works on Dannmar as well

    Bought this product as an addition to my Dannmar T100 tire machine, fit perfect, was easy to install and works great. Very happy with purchase.

Derek Weaver Company is proud to offer our high quality products with free shipping or warehouse pickup. Here's how it works...


All Products on our website are offered with "Free Shipping". This means the freight charges are included in the price. Most of our products weighing less than 800-lbs. are offered with “Absolute Free Shipping” which means there are no extra fees. In this case you will notice the phrase “FREE SHIPPING! Includes Free Residential and Free Lift Gate Service!”, in the description of the products page. Absolute Free Shipping also means there are no additional fees for Liftgate Service or Residential Delivery. The only additional fee that you may incur would be if the address were changed during shipment which would incur a reconsignment fee by the freight carrier that we would only pass on if it were not our mistake.

For equipment over 800-lbs (most 2 & 4-Post lifts) there are some limitations for Free Shipping depending on weight and delivery location. In this case you will notice the phrase “Free Shipping To Over 85% of the USA - See Where It's Free” in the description of the products page. Most of the USA will require no additional fee. This applies to over 85% of the continental USA (lower 48 states). Free shipping does not apply to Alaska or Hawaii. Some parts of the country are affected by higher freight rates due to the combination of weight and delivery location which will require a small additional charge to cover the higher rate charged by the freight carriers. Our shopping cart will not calculate the difference (added fee), so we will contact you if this is the case. Rather than advertise the higher rates across the board we choose to show the lowest possible cost to most of the country. Like “Absolute Free Shipping” there will be no extra charge for lift gate or residential delivery. The following areas may have additional freight: North Western US, North Eastern US, Long Island, Western Colorado, the Dakotas, some parts of Florida & California and any area deemed a remote location by the freight company. Prior to ordering give us a call at 817-560-9510 or email and we can provide accurate information regarding Free Shipping or any additional charges.


Shipping and delivery time given during the freight quote process is an estimated time of delivery given by the carrier. Choosing Liftgate Delivery may extend delivery times due to limited liftgate equipment at the delivering terminal. Meeting the delivery schedule is subject to the day the freight is shipped and the carrier’s ability to meet their schedule. Derek Weaver Co., Inc. does not guarantee that a carrier can meet their projected delivery time but we will provide you with the proper tracking information by email so you can follow the tracking time and arrange for special delivery needs with the carrier as needed. Any additional fees incurred as a result of consignee being unable to meet scheduled delivery time or cause for redelivery or reconsignment to a different location will be at consignee’s expense.


Choosing Residential may extend the estimated delivery time due limited liftgate trucks at the delivering terminal, additional communication and handling by the freight company. Please keep this in mind when choosing residential delivery.


Make sure you can unload the freight. A forklift or lifting equipment is required for items over 800-lbs. The trucking company is only responsible for delivery to your loading dock if delivered to a business address or curbside if a residential lift gate delivery. Lift gate service is available for some equipment and can assist in unloading 2 and 4-post lifts however you will still need a forklift. Liftgate capacity is typically 1000-lbs and cannot unload a 2 or 4-post lift on its own.


If you are unable to unload a truck, we have the option of letting you pick the freight up at the closest terminal to your location. When picking up at a terminal, the freight company will load your truck or trailer for you which is included in the freight cost. Call our office (1-817-560-9510) to determine the location of the closest terminal. If you require terminal pickup please place a note in the comment box requesting terminal pickup and we will contact you with the terminal location. Covered trailers or trailers with ramps are not acceptable as they prevent the forklift from getting the load into the trailer. They will not drive onto a ramped trailer. Please remove the ramps prior to picking up if possible.

All shipments must be inspected immediately upon receipt



Choose this option if you have minor dings and scratches or a part that needs replaced to make the unit satisfactory. Make note of the damage before you sign the freight bill. You will be responsible for filing the freight damage claim with the carrier. Derek Weaver Co, Inc. will provide any replacement parts or touch up paint needed should you choose this option and the carrier should provide for reimbursement. If you have any questions or need further assistance, please call our customer service department @ 1-817-560-9510


Choose this option if the carrier has severely damaged the freight beyond your judgment of a simple repair. Derek Weaver Co, Inc. will file all freight claims. Get a copy of the freight bill from the truck driver and email it with a brief explanation of the situation to us. A replacement will be shipped as soon as we verify possession of the freight with the carrier.


If you would like to pick-up the item at one or our warehouses, please call ahead to make sure the item is in stock and schedule your pick-up. Picking up at our warehouse will save you in freight fees but will require sales tax to be collected.
