Hi all,

 

The starter on my 914 occasionally throws a hissy fit when it’s hot and I am looking into replacing it with 912S starter.  Are there any considerations I need to take into account with the ring mount or water pump?  My aircraft is an XS

 

Thanks, Paul

Hi! Paul, Suggest you get the heavy duty starter , but you may need to lift the engine forwards

To get it in. It is without doubt well on top of the job.

Paul, in 13 years my 914 starter has never given me any cause to doubt it, and I would wonder whether there is anything to be gained by changing to a different system. Certainly on occasions with engine & weather hot it might not start on the usual first or second go, but this is not because it doesn't turn the engine over nicely  but presumably because all the petrol in the carbs has vapourised or some such. If you have a conventional battery rather than an Odyssey or equivalent (which have much higher cranking power) I would be tempted to change that first. 

Regards, David Joyce, G-XSDJ

Hello David,



The on occasions the starter won't engage when the engine is hot and I have

done several starts. It mostly occurs when I am doing a prop balance. If I

tap (bang) on it then it generally springs into life. I have an  Odyssey

battery.



My guess is if I pulled it apart I'd probably find stuck brushes or

something.



I am hoping that the advantage of going to the heavy duty starter is that

it will end the occasional kick back.

Hi Paul,

Measurements I made years ago showed that the heavy duty starter motor cranks the engine 30 to 40 percent faster everything else being equal (same engine, same battery, same temperature), so obviously it does reduce the chances of kicking back. 

 I had to replace my dead HD starter motor years ago on my XS and I confirm you can do it quite easily. There is no interference with the ring mount, water pump or foot well.

Regards

Remi

Hi,



Silent Hektik says, the distance from the battery to the HD-starter should not be more than half a meter http://www.silent-hektik.com/UL_912_Anlasser.htm. It seems to be a recommendation to achieve the best effect.



Many of the 914-jockeys do have the battery installed in the baggage bay behind the seats (me too).



That said, I wonder, if it makes a big difference between a conventional and a LiFePo Battery.



On the other hand I don't have problems with the stock Rotax starter other than occasional kick backs on low/very low temperatures (with a conventional lead acid battery).



Regards

Hi! Roland,

Hope you are well and ready for a new flying season?

As you may have noticed my twin odyssey 13.5 amp hour batteries are mounted

on the passenger foot well. I would guess all of 12" or (300mm in your

speak) to the HD Starter.  Never a kick back and an immediate start up

without fail ......so long as you remember to switch the electric fuel pumps

on ! I will never forget the hassle I had getting the Jabiru Six cylinder

donkey to power up from the battery behind the seats ! Recommendations from

all and sundry until I used my own brain on the issue !

Regards

Bob Harrison G-PTAG. 914 Rotax.

Good morning Bob!



Yes, absolutely ready for the flying season and hope to meet you on Texel again this year  BTW: will anyone of you Europa folks be at the AERO-fare in Friedrichshafen 15th-18th April?



Moving the battery in front of the cockpit makes perfect sense, in spite of moving forward the CG as well. I was tempted to do this but missed the chance when I installed my whole new cockpit panel and therefore had the complete electrics and interior taken apart.



I just enjoy flying at the moment....



Best wishes

Roland

Hi! Roland,

Yes, keeping the centre of Gravity Forward makes sense since loads such as

fuel baggage etc move it back anyway !.

Ivor has mothballed his plane for the season due to hangar problems at Lydd

so he is going onto my insurance to keep his Hours in compliance.

We intend doing some smaller trips this season for that purpose (mine too!)

We aren't planning on AERO-fare in Friedrichshafen this year, no spare cash

anyway ! Hope to make it to Texel though but it clashes with the LAA Rally (

I think?) I would think the Europa Group would notice your question but I'm

copying this message in to David Joyce who is mostly involved in trips and

tours, perhaps he will answer you?......David ???

Bob Harrison G-PTAG

Bob,

forward this to Ivor - end of hangar problems. You know best, that the Europa is well suitable for rigging.
