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.

The rail spacing is the same so the 210 seats should work OK. I would ask if I could install one in your 182 before I paid--not sure about fuselage width, etc. But I believe you'll be OK

Bob,

Thank you for your response.

I am excited to know that there might be another cause for the headset noise and will try checking out the mags when I next take the aircraft out.

I will let you know.

Thank you again.

Luis

Not to hi jack your thread but I am contemplating sticking seats from a 1976 210 into my 1966 J model 182. I’ve already checked the width of the rails and they are the same, is there any other aspects that I am missing? Thoughts?

I’ve completed the break-in on my P.Ponk O470-50U in my 182J and REAL happy. Although I stuck with my original (overhauled) 2 blade McAuley prop, the performance is awesome.

We live in the Southern California desert. Evidently, the seal around my rear window has dried out. When I go somewhere it actually rains, I get water in the baggage compartment. Is the only fix to remove and reinstall the window?

Luis I must start with a show of appreciation for your service, Thank You.
Have you tried doing a mag check to see if it goes away? You are describing an ignition noise and this may help.

As a wrap-up to this post, I instrumented the airplane as I described below with four DVM's. See the enclosed simplified diagram. After doing all this work to hook-up, I could not get the problem to re-create in two days of trying! While briefly cranking the engine, I got pretty consistent voltages throughout the system that gave me no indication of the problem. A disadvantage with DVM's is the bouncing around of the numbers while it takes a moment for the A/D converter in the DVM to ramp up to the actual voltage, based on the sample rate. I had to somewhat mentally average the numbers. Anyway, I dismantled all this and returned the airplane to normal and will continue to monitor the situation and discuss it with my A&P at the annual, beginning May.

I looked into the ignition switch refurb kit as mentioned by Steve Ells. The ignition switch would be difficult to work on without disconnecting wires since the wire harness doesn't give much room for moving things around. I decided I didn't want to be working on this switch which controls the mags and mess something up.

Hello everyone!

I just installed a Garmin GNS 530W and an Aspen Evolution Evolution Pro PDF on my Cessna 182H.

After that, I have a "tick.. tick.. tick..." radio noise on all my headsets that cannot be isolated on any equipment. I have a Sigtronics SCI-S4 intercom that I had had for the past 15 years with no issues. My avionics shop told me that I have to replace it, since the wires on it is not shielded, it's cheap equipment and it's the cause of the problem.

Does anyone have any experience with this?

I appreciate any information or suggestions.

Thanks,

Luis

Hi Kent,
Always check with your mechanic or avionics tech first before starting any work.
Best,
