I installed new pilot/copilot BAS 4 pt inertia reel restraints in my '69 182M and if feasible would like to reinstall the removed 3 pt harnesses in the back if the necessary airframe attach points can be fitted. Advice is appreciated.
Thanks,

When there's a small leak in the system (powerpack, actuating cylinders) the pressure in the system bleeds off untll the pressure (sensing) switch mounted on the powerpack closes. This completes an electrical circuit that closes the landing gear motor solenoid, which turns on the pump motor/pump assembly to build the pressure up to 1500 psi.
This “re-charging” is not abnormal but “re-charging”10 to 20 times an hour indicates the leak is larger than desired.
There is a detailed procedure for this problem in the troubleshooting page of Chapter 5 of the airplane service manual. The troubleshooting guide describes the problem as regular “re-charging” of the system and landing gear doors sag open between flights. The manual cites leaks in the door close system as the problem.
If, after walking through the steps in the troubleshooting guide, or if the doors and actuating cylinders have been removed in accordance with an approved modification, the leak may be internally in the power pack or by internal leakage in one or more of the landing gear system actuating cylinders.
The power pack leakage can be a bad thermal relief valve, check valve or check valve o-ring. The parts manual shows where the o-rings for the “self-relieving check valve” and the “thermal relief valve” are located and the part numbers for the o-rings.
If there is still a bleed down, one or more of the main or nose landing gear actuating cylinders has internal leakage. Remove the fluid return lines on each cylinder—fluid dripping out of the return line port when the system if pressurized indicates an internal leak in that cylinder.
Removing, disassembling, repacking and reassembling the cylinders is not difficult but should only be done if your mechanic has the service information about the dimensions of the parts and the equipment to test the cylinders after rebuilding. This information is in the service manual for your airplane.
All work on the hydraulic landing gear system components is very detailed and “clean room” procedures should be followed. Almost all of the rebuild and refurbishment procedures are in chapters 5 and 5A of the service manual.
Good luck and post what you find so we can all benefit from your experience.

Thanks Steve, that’s the current plan

Some mechanics are applying fuel tank sealant (www.aircraftspruce.com/catalog/cspages/a...php?clickkey=1820334) in a ribbon that covers the joint between the edge of the metal window frame and the edge of the window with pretty good success. It takes about a strip about 3/8 of an inch wide.
This is a two part sealant that is tough.
Part of the problem is the original sealant dies up and migrates as it ages and the window has a different expansion ratio/heat than the airframe. So the window and the frame move in relation to each other.
The other option, which might be wiser in the long term is to buy a canopy cover that goes over the rear window. There are a number of companies that make these covers. One that's been around a long time is: www.aircraftcovers.com/182.
