CAE kept with round circlip, which never came out but were a difficult to fit in situ.Not only was there square circlip quality problems, they bent, but they were/are punched so have round and square edges, wrong way round can come out.

There are several people looking for replacement pistons if someone knows of source and skills to machine in round pin groove

Having pistons made up these days is simplicity itself,i've done it for motorcycle pistons.Usually a minimum of 4 are supplied.And you can go back in 6 months and have that piston exactly replicated,just quote the build number and they punch that into there computer and that's that,identical pistons to the originals.Is there any reason owners shouldn't be fitting forged pistons in these 4 cylinder motors,and are the 6 's susceptible also. Also +040" pistons suggest heavy piston,not ideal.

This thing about the video being shot in portrait may not be his fault,i had some video's of my Supapup but after my laptop came back from a repairer

 

they are all in Portrait too,and i haven't been able to change them back.

Must get pretty expensive,i have a MSIC (marine) paid by the company and it has to be updated every 2 years which means i have to resit the test that goes with it.

 

Think i'll stick with RAA as well.

The mystery clicking of this type motor has been solved ,Rod from Jabaru says it is the "permanent magnets in the alternator and the gear drive of the

 

alternator"the clicking transfers all the way through to the Prop.If there's no clicking then some thing is wrong.

Retension the studs that go through with spacers, before rotating the engine. Protect the cases from damage by the conrod dropping in it. (Just general advice). Nev

No worries Nev,haven't had a chance to get back onto it,and leaving for Wanaka monday so will be away few weeks,but the clicking is definitely not coming from the

cylinders according to the stethoscope,and it's exactly the same hot or cold. colin

 

 

Check how much the engine is breathing. You may have a ring of rust in some bores and that could do bad things to the piston rings.. End float noises are usually intermittent not regular and are worse when hot. Nev

thanks Nev,will pull one cylinder today if possible,looks like head and barrel are 1 piece,

cheers

We've now gone thru and got oil circulating,engine started and runs fine,but low compression on one cylinder,looks like we''l have to do a valve job all round.However the clicking noise is still there,even after the motor was run for 15 minutes.I'm now thinking it may be the magnetized alternator rotor,and clearance in the accessory drive gears moving back and forward.I realize there's basically no parts for these relic's from the past,does anyone know someone with KFM experience?

How long is a WHILE and was it inhibited? You can't just let motors sit and then fire them up and fly years later. You should pressurise the oil system before running and check cylinders with a borescope and check all valve guides, particularly the exhausts for corrosion and sticking. at least, if the storage period is significant. Nev

Good point Nev,it could have been a number of years, will make a phone call.As to the pressurizing,that's a good idea too,i imagine that will require removing the oil filter and pumping oil through the outlet.Will report back how we go.

Well i've done some searching and it's possibly a dry Gerator oil pump.Just needs priming possibly.Will have a go at it this morning,fingers crossed

 

 

I guess that's a possibility,but the sound appears more to the front of the engine.

 

 

Hi guys,engine is a KFM 112M ,hasn't been run for a while,only 300 hours.When turning the motor on the prop there's a clicking noise,somewhat like a impulse connection but more a clicking evenly spaced and not as loud as an impulse.It's there turning it either way,and there for the whole revolution.Evenly spaced,like every 5 degrees.Motor turns smoothly,no grating .It seems to be coming from the front.

 

Any ideas before a complete teardown ?

Milz,yes i've been up through the Alps,from Midura down the Murray then up over the Alps and ended up at Mum's in

 

Pambula.Skiers out to the left of me,beautiful clear skies and about minus 10C,does it get any better:thumb up:

 

Hongie,if that's the blue Sav i've flown it that out at Nebo,i snuck some time in when it was out doing some flier training,

 

about 1.5 by memory.

 

cheers

Wow guys,i've been away for a few weeks and have just tuned in again to all these replies.I went to the "Old station"

 

flyin ,what a terrific event,and the Trojan and yak were kept working constantly.Can see an air show coming up soon

 

after that turnup.

 

Just returned from Cooktown and Cairns and got to see 2 Storch's,on the way back.I'll keep looking something will

 

turn up.

 

I've got a 1951 Royal Enfield 500 Twin,been an interest of mine for 40 years these early Twins,don't know why but i

 

love to get away on the odd Rally and catch up with like minded individuals,the Inverell rally is just one of many held

 

around the country.

 

Thanks for the offer of a hanger too,i'll be looking in to that one,will be a little busy from now on due to work at present.

 

regards

Thanks Pud! To you and yours,also!Havn`t been flying since the rain started a week ago and I`m getting withdrawal symptoms.

Frank.

Hello Colin, .You reckon it`s been raining at Mackay! Here at Deeral, we`ve coped 12 inches/ 304.8 Millimetres just in the past two days!

 

Frank.

Aw shucks Frank,i was just trying to make conversation.I don't really mind the wet up here.But the RA flyers are not to friendly up here.

 

Colin.

 

 

Hello fellow aviators,just wishing to touch base,i live in Mackay (yes sunny Mackay where it never stops raining lately ) . Have been out of flying for some years and just came back from a road trip (m/cycle rally at Inverell) and included a short flight in the Sierra at Taree.Awsome plane that,fantastic vis over the nose.

 

Anyway i've been looking to get into ownership and had been stuck on the Storch for years but who knows.

 

Any spare hangar space out Palmyra guys?

 

cheers
