Parts came with no instructions. Removed 4 screws to free parts assembly. Saved felt strip on back of filter guide and spring on filter cover. Assembled parts, after fooling around with spring to get it working properly, and reinserted into dryer. Note: better observation when disassembling parts initially would have saved a little time. Aligning assembly and getting screws back in also took a bit of effort and required getting head and shoulders into dryer opening to see fit. This was a little awkward, particularly with placement of flashlight. Once done, the new parts fit like a charm.
