Alexandre,



I also have a h6 prop it is number 5164.



If your prop is between number ap2902 and ap5299, it should
have been

recalled and rebuilt for free by autoprop.

Hello Eric,



I tested all the Air conditionning Capacitor (and changed
some) a few months

ago, so am familiar with this process.



I just check the bill from Amel (last November), they
greased the prop. I am

sure if they had seen it needed new bearing they would have
mentionned

something... Which prop do you have? I have the Auto Prop
H6.



Sincerely, Alexandre

The prop rebuild is a time consuming project and is

best done on a workbench



with a vise.



I bought the parts from AB marine for about $900- they

rented me the tools



(cost $350- for 50 dollars-upon return of the tools) I
think

it will take



one person a day plus to do it.



The hardest part is to remove the ball bearing race as it
is

held in by



grease and the tolerances are very tight. It takes a lot of

time and solvent



to remove them.

Subject: Re: [Amel] Re: Turbo desapointment...



Good morning Gary,



If the Marina was cleaner, I would dive myself, but it is
so

dirty...



Not much clean water in "Clear Lake", but I think

I should make an effort



and dive far in the bay.



The propeler was lubed last November. I don't know
about

the last time the



bearing or blade seals were changed.



I was planning on disassembling it in Nov before my trip,

may be I should do



it before.



I recently changed both Engine fuel filter and (single)

Racor fuel filter. I



don't think, but don't know if I have restriction.



I will check the valve.



I don't have suction gauge, any recommendation?

Manufacturer? I am not



familiar with that... Are they permanently mount?



Thanks for the compliment in cleaning the turbo... I wish I

could brag about



2800 rpm!!!



I will looked at the "Mouse Milk" you mentionned!



Thanks again for your email, let me know about these
suction

gauge...



Sincerely, Alexandre

Alexander:



A couple of thoughts:



Find some clear water, dive on your prop and visually and



tactilely verify for yourself that the prop is bristol



clean!. I hired a diver once to clean mine due to the nasty



water in the marina, and after he said it was clean, I



subsequently inspected it myself and found it was anything



but clean. I find that even minimal incrustation on the



prop takes me at least 30 minutes of scuba/snuba time to



clean properly. Heavier growth can easily consume an hour.



Use a putty knife and some 3M scotch bright or equivalent

to



get it completely smooth, including the hub area.



While you are down there verify that your prop bearings are



good. This requires a bit of a fine touch. Just slowly



rotate each blade, one at a time, manually and see if there



is any binding, gritty feeling, or roughness as they rotate



around. This obviously is easier done when hauled out but



can be done underwater. What you are looking (feeling) for



is any sign that the bearings in the blades are gone. They



should be silky smooth as they rotate and should certainly



move freely. On that note, when was the last time the prop



was lubed, when was the last time the bearings were

changed,



and when was the last time the blade seals where changed? A



prop blade with bad bearings can give strange vibrations



while powering.



I do not allow any pressure washing of my prop when hauled



as the high pressure can easily blow past the blade lip



seals and water contaminate the bearings. When you lube



your prop if you have water exit the vent hole then you



should consider disassembling the prop for bearing



inspection.



Are you absolutely certain that you don't have a fuel



filter (there are two) restriction or fuel line restriction



such as a bad fuel tank shut off valve? Verify that the



fuel tank shut off valve is properly rigged and fully open.



Have you put a suction gauge on your fuel filter to see if



the filter is restrictive to flow? Just a couple of cheap



and easy things to check.



Good work on cleaning and verifying the turbo spun freely.



There is a product called Mouse Milk (that you can get from



AircraftSpruce.com) that we use on the waste gate actuators



on aircraft engines to keep them limber. Cheap and easy.



Sincerely,



Gary Silver



This evaluation won't cost you much in time or money
