Well, the weather has finally turned comfortable enough that I can get out and do some needed maintenance on the 1711 hydro. I have needed a new fan for a few months and just recently I have noticed the hydro suddenly surge forward when normally it would have a consistent pull and only change speed when the hydro handle was moved. I knew that the hydro cam plates probably had some slop at the pivot pins and the trunion springs were probably week. On the plus side, upon inspection, the trunion had absolutely no wear, so no welding was needed, but as mentioned above all the other issues were present. I removed the plates, steel wheeled them down to bare metal and primed and painted them. There was around 3/16" gap in the big spring of the trunion. I found a washer that fit perfectly and removed all free movement of the spring. The trunion cam plate had back and forth slack from wear. I had some shims left over from a prior QL trunion fix and ended up using all of them, (8) to be specific to remove all the side to side slop of the plate. It now centers up over the springs perfectly. I should have it all back together tomorrow and it should be good for another decade or two.
Back home from getting the tranny and frame washed off at the carwash
Nice and clean hydro, it was pretty nasty, sorry no before pics
Pretty new fan installed too
Nice and clean again
Plates cleaned and painted
Looking kinda sad
Trunion not worn or welded on.
