Removal of a broken slide cylinder
#3

I was able to rebuild one of the slide cylinders today except for the wiper seal that I originally bought the wrong one.

Some people have had problems removing the check valve block on the piston side of the cylinder. I was able to easily torque it off putting the block end in a vice without clamping on the little raised balls, and using the nuts on the end jaming them together.

For peoples reference, the part numbers are as follows to rebuild the slide cylinders:

Slide cylinders is HWH AP15845 but same as HWH AP21812
The O'ring store UL125-0.875-125 High Performance Loaded U-Cup
The O'ring store AN-07-SH 7/8" Rod Wiper Seal (This was the lowest price for MS28776-7 I could find by far)
The O'ring store AS568-916 Buna-N 70 Duro (I used a 3mm x 30mm seal sized off less than 2% since I did not know there were special oring sizes for "bosses")
McMaster Carr Oring 9452K34

I was lucky enough to get a HWH AP15845 rebuilt cylinder from Richard that I was able to slide right in. I happened to call Newell who had a seal leaking HWH AP21812 cylinder from a coach they were repairing while I was ordering some other parts. They sent that leaky cylinder to me as it had the same designed rod lock mechanism (the rectangular block on the rod end of the cylinder). So apparently I can make a spare working cylinder of either part number, however I will build it as the one I need (AP15845) since I am already a mess.
