This the best I can do. The handguard is an early one with no viewing windows. It has the spring to keep pressure forward but the saw did not come with any other brake parts. I have looked around for some but didn't have any success finding any, especially with the older style brake band. This project was to get the saw functional on a budget. So, I'm not investing a ton into it. I'm not even sure that the saw came with the brake parts originally. I just have to figure out how to keep the plastics from rubbing and melting from within.
The saw looks pretty clean/nice, so I'm going to assume the clutch drum bearing and inside of drum are O.K.?
A bunch of the covers are on ebay now, with pictures 1100, 1102, 1103, 1104. The first three have the part/protrusion that goes towards the bar studs, on the 1100 it's a little different. The inside of the 1100 is a little different. The 1104 is missing part that goes towards the bar studs, but inside is similar to the 1102 and 1103.
I grabbed screen shots of 3 of them, 1100, 1102 and 1104:
Sometimes I find ebay useful......
Did the 028 have any changes in the clutch carriers too?
