Replacing Upper String Trimmer Shaft on Ryobi Gas Weed Whacker (RY252CS, RY253CS) - by DIYNate
DIYNate shows how he was able to take an old upper shaft boom assembly off a broken Ryobi gas 2 cycle (25cc) string trimmer power head and put it onto a working Ryobi power head that had a bent connection end. This process covers how to remove and reinstall the shaft, but doesn't get into changing the trigger mechanism out.

In this video, DIYNate captures a garage project that had been waiting for a while. He had some Ryobi string trimmers (RY252CS and RY253CS) models that had damaged upper shafts - from wear and tear on the connection ends - where the upper shaft wasn't securely holding the lower shaft and the clamping mechanism wasn't able to support the lower shaft weight. He was surprised to find how easy changing one working upper shaft assembly from a broken power head to a working power head was. Many people may not have the luxury of having two string trimmers that both have complimentary working and non-working parts to 'Frankenstein' together a working Ryobi string trimmer, but hopefully, this video gives people an idea of how easy replacing the upper shaft can be.
Tips: Probably best to remove the gas while you are working with the unit. Getting the upper shaft to fit into the power head can require a bit of patience. I didn't go after opening up the trigger assembly, but I am sure that is more complex than just swapping out the head. I did find a helpful video on an older model Ryobi string trimmer from the crew at eReplacement parts that may be helpful for going into all the details (although the model is slightly different) - • How to Remove and Replace the Upper Shaft ...
Steps:
1. Empty fuel to avoid spilling
2. Disconnect the spark plug
3. Loosen the T20 Torx bolt (bigger of the bolt) on the upper shaft connecting it to the power head (shouldn't need to take this all the way off but loosen significantly; there is a nut on the other side so be careful not to lose that)
4. Remove the T15 Torx bolt (smaller of the bolts) on the upper shaft and set aside; this will be put back into the replacement upper shaft and needs to be aligned when reassembling
5. Take off the air filter cover and remove the air filter
6. Take off the carburetor - 2 bolts should allow that to come free
7. Disconnect the throttle cable from the carburetor and detach the throttle cable guard from the plastic carb/filter housing
9. Disconnect the red and black wires paying attention to which wire is which (may want to tape or label them)
10. Pull the old upper shaft out of the power head and prepare the new upper shaft for assembly.
11. Put the new upper shaft into the power head, working to fit the inner rod into the socket that will spin the shaft; it should make a very good connection when you correctly fit it.
12. Follow reassembly steps (reverse order from above to reconnect) - you will likely want to secure the T15 Torx bolt and T20 Torx bolt first though, ensuring your new upper shaft stays connected while reassembling the remaining components.
13. Run throttle cable through plastic housing securing throttle cable guard then attach throttle cable to carb. Connect red and black wires. Reattach the carburetor bolts and put air filter/cover back.
14. Finally, reconnect spark plug, replace oil/gas mix into the gas tank, and crank your string trimmer to test and ensure everything is working as expected.
