Hi my name is ***** ***** will be glad to try to help. The external seals are just dust seals to prevent contaminants from getting pulled into the cylinder. There are internal seals that actually seal the cylinders high pressure. The cylinder needs to be rebuilt and a complete seal kit installed. Let me know

I understand it is a dust seal that has nothing to do with it getting pushed out is there any special procedure for the correct installation process to prevent that from happening

Is it leaking oil? Meaning is oil pressure pushing it out? If not, Take a close look at the gland where the seal goes as the bore could be worn or the gland bushing where the rod slides could be worn. Too much play between the rod and bushing will allow the rod to put tension against the seal and pop it out. If this is the case the gland bushing or gland will need to be replaced after disassembly an inspection. I agree to disagree with you that it has nothing to do with it. I have rebuilt many cylinders over the years inside and outside of the dealerships on cylinder benches. A worn gland will cause this.

the seals are normally installed with the cylinder apart. In cases where a seal is loose fit aside from replacing the gland you can use a pointed punch and peen the metal to create burrs where the seal holds /press fits in the gland and use green loctite( bearing mount) to assist in holding the seal. This still needs the cylinder apart.
