"we are doing the annual maintenance on our IV-P and noticed some oil
seeping around the bottom allen nuts at the base of the gear leg. We
serviced the strut as per the manufacturer recommendations with 20w fork oil
and noticed that the bottom allen nuts (three) were a bit loose. I cannot
find any guidance re torque or other recommendations. There are also 2 nuts
2 inches above in the front of the strut which are safety wired and there
appears to be some minor oil leak there. The recommended strut service
should be done every year and 3 inches plus minus 1/4 inch should be
showing. Mine required 250 psi nitrogren which is within tolerance."

This is from David Watkins at ESCO ....

"We do not specify a torque for these cap screws, just do them up tight with
a standard Allen key. I might point out that they do not need lock wiring
because there is a natural locking action by virtue of the gas pressure. The
gas tries to push the Cylinder Nose out of the Body and is only stopped by
the cap screws. This forces the outside diameter of the Cap screw against
the bottom of the clearance hole of the Body Tube thus causing a locking
action."
