RDP'S "What are you working on?"

[530RL]

That's pretty cool! In my world, I get all excited when it gets to the point of firing up the engine. Never had a turbine to play with though.

How long before it's ready to flight test?

The engine oil sump tank is above the engine and has a pressure actuated check valve to keep it from all draining into the engine gearbox and overflowing onto the ground.

We turn the engine over to get the oil to drop out of the sump tank into the gearbox and refill until we get to the prescribed amount necessary to fill the compressor/gearbox/turbine and the sump tank.

In the video you can see the N1 spool up, the ammeter go negative and the oil pressure start to rise. When the oil pressure rises, the check valve opens and allows us to add more oil to the sump.

Waiting on the clutch overhaul. It failed inspection upon re-installation.

Does the upper portion of the assembly need to come off to replace the clutch? I assume the engine stays located in the fuselage (I think that's what you'd call it on a helicopter) otherwise I doubt you'd be filling the sump. I'd guess it has a large sump capacity and a big cooler as well. The rpm alone would create heat without a load.

Clutch is in the housing that connects to the engine gearbox.. Where the yellow rag is here.

The clutch is then connected to the main rotor transmission via an engine drive shaft between the two.

You can see a clutch in here during engine alignment. The engine drive shaft goes between that clutch and the upper coupling on the main rotor transmission. Where the measuring tool is located below.

I'm surprised only four bolts attached on the flanges for the shaft. Are there safety wires on them, or just lock washers and Loctite?

Fire waiting to happen.

This thing is the Winchester Mystery coach. I wired things the way they are supposed to, and it stopped running
It had been getting parasitic voltage to the wake up power for the ECU. It made it here on hopes and dreams. Chasing corrosion first, then this afternoon a broken wire for ignition.

Never seen it before. Normally I just grease it up with dielectric grease. It helps with the corrosion, but attracts dirt and somehow seems to glue the weather seals in place. Need to look for a brush on type. With the spray, I think I may end up looking like the tin man.

Went to jump in the '48 Ford Sedan Sunday morning to head to Boathouse on the island for the morning cruise. Damn thing wouldn't start. Just starting to diagnose the issue. Going to start with fuel, but thinking that is ok as I tried getting her kicked over with some starting fluid and that also did not do the trick. Hopefully I can get it figured out pretty quickly after I return from Del Mar for a wedding this weekend.

Washed and detailed my F350 to put it up for sale. My 25 HO will be here next month.

I am ordering a 2025 F350 - wondered if you had any concerns over the HO engine option. I may stay standard, less heat exchangers, additional cooling circuits, etc to go wrong. These damn things are so complicated with emissions equipment, etc.

The whole thing is like Chinese arithmetic, so at this point, send it. Buy an extended warranty. Let those bastards fix it. Get rid of it before there's problems. At least that's my theory. My 21 is basically the same thing and it's been flawless enough for me to buy another. Coming from a GM guy.


I'm really looking forward to the HO . a buddy of mine who owns a dump truck company just got a 24 HO. Says it's fast.
