Hose placement/Plane power alternator

[Jim Peace]

While doing my extensive annual my mechanic found that the mechanic who did an AOG generator change years ago did not install the generator correctly.  You can see in the picture that the belt does not line up with the pully etc....

 

Long story short I decided to do the Plane Power alternator STC.

 

It all lines up now but I noticed that my mechanic has put the hose on the forward side of the bracket now instead of the aft like it was with the generator.  ( I did all new hoses firewall forward by the way.)

 

It is a very rigid hose and is not going anywhere but I just would like to know if this looks OK and safe, legal etc.....I will be asking him about it this week.....

 

Also how good is this Alternator belt?  The gates 9335 green stripe XL

 

Pictures enclosed,,,one from before and two after...

 

sorry for the pictures not being shown as I took them....no idea how to make them right side up

Jim,

I don't think there is a specific location for the hose, as long as it clears everything and does not contact moving parts. The original propeller governor oil transfer line was stainless steel and normally went behind the tension arm if that is any help.

I think I'd rather have it the way it was originally, but the alignment was catty-wumpus before so this is still better.

As for the belt- don't worry. If it doesn't break in the first 5 hours it'll probably go 2000. Cheap and crappy generic belts last 2000 hours all the time.

thanks

Ok. I can't resist the comment on the gates belt. This is my first post. I am second generation in our family auto parts store. We have sold gates belts for 48 years I think they are as durable as anything you can buy.

I enjoy reading these topics. I too just added a Plane Power alternator on my 66 e model.

Welcome!

Some time ago Gates made belts for Lycoming. Like so many parts they were off the shelf automotive parts supplied from the same manufacturers. liability concerns have driven them away.

Here's something I cut out of AC 23-27 Parts and Materials Substitution-

Now if the belt was part of the STC'd kit and called for by name and number in the STC then it is legal.

The A/C specifies how a belt substitution works if the original part is NOT available.

Another FAA gotcha!

1. DRIVE BELTS

a. Alternator or Generator Belts.

(1) For aircraft where the manufacturer no longer sells the original alternator or

generator belt, you may use a belt made by the same belt manufacturer if the original part

number is known. If the original part number is not known or the belt is no longer available, you

may use a belt manufactured to a known specification such as SAE J636 and the belt properly

fits the application. Pay special attention to fit of the belt to the pulley and proper tension of the

belt. We highly recommend the use of technical information from similar aircraft.

(2) The SAE J636 specification covers standard dimensions, tolerances, and methods of

measurement of V-belts and pulleys for automotive V-belt drives. The V-belts that Piper

supplies for the PA28-140 conform to this specification.

Approval: This is a minor alteration and you may document it by a logbook entry. The logbook

entry must reference the original (if available) and replacement belts' specification and

manufacturer's identification.

When I purchased the plane power kit from Spruce I asked them to send me the belt that they thought would be for my plane.  They sent a wrong size, I spoke to them again and they said they had no idea, it was just a guess.  So then I called plane power which is now hartzel.  They had no idea what to use on an M20C.  Long story short I have what I have......

 

So has anyone used the gates 9335?

 

I will not be testing this out for a few more weeks.......

 

By the way has anyone noticed that the sales people at Spruce have absolutely no idea about any of the products they sell.  Many of the sales people would not recognize an airplane on a ramp....They have a nice catalog and nice place in Corona but they really need to educate the sales team. Do not bother asking them any questions about anything......

When I replaced my generator on my 64E models I used the same belt to avoid removing the prop.  It worked fine.  The prop governor line did need to be tweaked and shielded to prevent any interference with the brackets.

Here is my 67' M20C Prop  govenor rigid  oil line routng with plane power alternator (before plane power's conversion kit) on  an O360A1D wide deck engine without front baffling installed. I had problem at the ohter end where the oil line attaches to the prop governor. The rigid oil line was too close to the top of the front passenger foot well, Lycoming parts manual was hard to match the part number to the different dash number. I will try to find better  picture of the prop govenor line.

jamesm- just by seeing the picture it seems that the B nut on your oil line is blue. Is it? If it is it may be aluminum and needs to be changed per the AD along with both crankcase fittings to steel. Just askin. Have you ever checked it with a magnet?

[Guest]

Check out AD90-04-06R1, the propeller governor oil transfer line B nuts and the 2 end fittings must be steel.

It looks like faded/chipped black paint to me, therefore steel.

[jamesm]

It is  a black and and it is steel fitting.

Thanks,

I had the same problem with mine, we went to the local auto parts store and brought back a few, I think my belt is a gates unit but the one that is heavy duty for commercial truck applications - only because they didn't have that particular size in standard belts in inventory at the time.  Thanks for the post/pix so I can go buy a backup and keep it handy in case it breaks.
