Reviews

The part was a good fit.
July 13, 2023

The only problem with the part was number one took twice as long to arrive, and none of the bolt holes were threaded. We had to thread them before we could reassemble.

Had to tap the bolt holes! If you don't have a tap and die set look else where!

String trimmer head replacement
August 03, 2022

The new unit was easier to install than it was to take the old one out. Since the bolt holes are not threaded run the bolts in/out before you put it back together.

Not OEM, but almost.
July 19, 2022

It's a good thing I ordered the spindle assembly and not the individual parts I thought I might need as I'm not sure the new parts would fit an old spindle assembly. As it was, I needed to thread one mounting hole (truth be told it was suggested to order a bolt as unit was NOT threaded) and enlarge four other mounting holes (no mention of that) to install and use new part. A pricey fix ($141.00) but easy enough even with these minor issues.

Worked very well
July 20, 2021

After comparing prices and factoring in time and labor, I decided it was easier to replace the whole spindle assembly as a unit than just the broken line holder. The placement of the bolts in the housing was problematic and the self tapping bolts were a ridiculous cop out but it all worked. Here's a tip: clamp the assembly gently in a vice and run ALL FOUR of the self tapping bolts in all the way then take them out. Then hold the assembly in place on the machine and start the bolts in the holes. Now the threads are cut and you can turn the bolts with your fingers which is a huge help.
