There are 5 release points on the line cover. The cover clips on at the front. There is a clip immediately behind the spool (big one), 2 smaller ones to the side of the spool and two stiff ones at the rear. Release the rear ones first, and hopefully the middle one will come loose. The ones on the side are minimal.
With the spool facing you, remove all the screws and ease fast the red angle adjustment lever. Remove motor etc as required. The spool is glued onto the spigot. Once off, the motor can be stripped and the bearings pulled (2 long screws). Brushes are easily accessible 5x8x20mm. 24 segments on commutator. Top bearing marked WT00 698Z. Resistance L to brush is 5.9R, L-N 22.0. Same with N. (Isotech meter)
Small drop of oil put on bearings
Reassemble and glue long motor screws and spool.
This was the first strip from new (2007) as there were no marks on the plastic. Minimal grass inside.
