This past week I also found a safety issue with the length of the bolts that mount the prop extension to the engine flange. When I bought the plane, the prop and extension had been removed from the plane and a AN6H-13A bolt was with them that we thought was the proper bolt. However, I used an endoscope last week to check how far the bolt went into the flange lugs and was surprised that it didn't go in far enough. Lesson learned - don't assume that a bolt is proper even if it is provided with the assembly. I purchased longer bolts this week to try. I purchased both AN6H-14A and AN6H-15A to see which works best. What have you all found is the best length where you engage the most lug threads without the shank contacting the threads?

I sent the co-pilot seat out to get the vinyl covering re-glued and cleaned up a couple weeks ago. Got it back this week and am very happy with how it turned out. Sent the pilot seat out to get done the same way this week. I'm keeping the same, original vinyl so I can get it back flying sooner. I'd like to have headrests, but they'll have to wait. I asked the guy what is best to use on vinyl to clean the white area. He said to use "Bleach White Whitewall Cleaner". If I have to restore any of the orange vinyl he told me to use "SEM" vinyl dye.

You are correct. AN-363 is the best option for the engine compartment. Cubes |

This is the reason why I removed the engine. The rubber engine shock mounts were sagging really badly. Severe mis-alignment from years of age. I'm not sure if they are from when the plane was built in 1974, but they were the original Lord mounts (J-7401-3) specified in the plans on sheet 479. I don't see anything in the log books regarding their change-out. Anyway, as stated elsewhere, I'm replacing them with Aircraft Spruce part # 08-03600 which is the beefed up version of their 08-3500, which is their equivalent to Lord mount J-7402-5. I'm so glad you guys are so helpful because, as a newbie, I really struggled to figure out what to get.

Tonight some of my EAA Chapter 45 buddies came over and we pulled the engine and the main gear off the fuselage. Five buddies and 5 hours later...

I'd like to know what is the best way to clean the oil and grime off the engine while it's hanging in the basement. Should I use a particular solvent/cleaner that you like best? I don't mind getting engine cleaner on the floor. I don't think I will use 100LL or kerosene because of the natural gas hot water heaters in the basement. |

In your case aerospace simple green might be the best option , especially with the IED's in the basement (hot water heaters) . I don't like to use water on my engine (simple green) or any other water based cleaner . I move my AC out of the garage on the trailer and with the cowling removed (annual) I use Jet-A (JP) from a 5 gallon can propelled thru a Milton high pressure siphon sprayer nozzle (90+ psi) . You can get the Milton sprayer on Amazon for about $20.00 . If you want my HF sprayer you can have it for free . The JP removes the grease , dirt and oil from the engine compartment and leaves no residue . Does not promote corrosion like H2O and it is safe on the paint . It is also very cheap compared to other solvent based cleaners (even 100LL) "I love the smell of JP in the morning !" RB |

Hi Rich - Yes, the 100LL and water heaters would be bad for the house. Thanks for the offer on your HF sprayer. I'll let you know if I need it, but the cost of shipping it is probably the same as if I bought one, right? I had purchased a can of Gunk Engine Brite on the suggestion of a couple guys in Chapter 45. If I went that route, I would rinse with water and then blow off any remaining water with my air compressor hose to reduce rusting. Do you see any problems with that approach? |

Yes the HF was a joke ! They don't pick up enough liquid to really do any good . The Gunk/rinsing route would work , but in my opinion it still leaves to door open for corrosion and rust even with trying to blow off the excess with compressed air . I suppose in your situation where you are limited to cleaning in the basement this procedure would be better than no procedure . RB |
