Is there a good long "crowsfoot" or tool that I can use to torque the bolts on my propeller??



Hope to be at Oshkosh this year.

Thanks...Greg

Make one. Take a good quality open end wrench of the correct size and weld a

3/8" socket extension on it at the center. You will then have a wrench to

use with your standard torque wrench.

Greg  

They make a special adapter that connects to a torch wrench google prop torch adapter you will find it.  It is like a long crows foot.

I seldom pick on spelling errors, but you'll get some really weird results with that search!!!

 Try 'prop torque adapter'.

Forgot.... You then can carry the wrench in your custom tool box for the 10;

don't forget to carry an additional spare O ring for the prop. Chances are

small that an FBO is going to have the O ring if you break an alternator

belt somewhere and need to change it. You will probably find the belt at any

auto parts place but the O ring is another matter. When my TC177RG was

turbo-ed the STC shop installed the wrong O ring. It seeped for 15 hours,

then blew out on takeoff from KSAT. Finding the correct O ring took two days

(because it was a weekend).

The alternator belt should last at least a couple of years, and you 

should check it during your conditional inspection.  If you're worried, 

put another belt on the nose of the engine and tie it back to the lift ring.

I think that's one of the reasons for having a backup alternator.... you just keep on going until you get someplace where they have everything you need to fix it..

Redundancy is good.  I have a Bo driver friend that carries a spare wheel with tire & tube .... just in case, he says.  I pointed out to him that most FBOs will have spare tire/tube available, or can get one on short notice.  But, he says, he goes places that don't have any service ...... so now he carries a jack too.  Hasn't checked his weight/balance in a long time is my guess!

 I try and cover the things that fail often ..... so I don't carry much.  I've never had a flat, never been stranded by a bad battery ..... just never had a failure except for engines, and I doubt I'll carry a spare for that!  But maybe I'm just lucky

Avery tool makes a special wrench for torquing the prop bolts



I bought one - a bit pricey - but does the job

Harzell sells one for about $200.....

Thanks everyone...

I'll make sure I have an extra "0" ring in the toolbox.

I have heard that some Lycoming operators put a second, spare belt over the prop and flywheel, and somehow tape it onto the engine out of the way, so they don't have to pull the prop to replace the first belt. I've never actually seen this, though.



Cheap crows foot:  Go the the hardware store and get a cheap nut and bolt of the same size you need to torque. You want one where the threads go all the way to the head of the bolt. Tighten the nut onto the bolt. Put the nut into one end of your wrench (use tape to keep it there), the other end of the wrench goes on the prop bolt or whatever you need to torque; your torque wrench goes on the head of the cheap bolt. Calculate the setting needed for the torque you want, and you're done.

Re-reading, I see someone else heard the "put a spare belt on" trick, too.

The downside of the extra belt is that it has already endured the heat, etc

and may be dried/cracked/inflexible when needed for use.

Yup, it's true.  However, changing it every 5 years like your hoses (you 
	


change the rubber hoses every 5 years, don't you???) along with the 

working belt makes this a non-issue.  The weak link seems to be the 

alternator bearings from having  the belts too tight.  Properly 

adjusted, there's really no reason for the belt to fail prior to the 12 

year/2400 hour recommended overhaul cycle.  IMHO, of course.
