Posted: Thu Oct 06, 2011 11:44 am Post subject: Recommendation M-14 engines

This should probably be on the M-14 engine list, (which I will get around to doing), but for now just a recommendation for every M-14 engine owner on this list.  (Of course this might equally apply to Housai engines as well! )

  

 As anyone knows who has timed an M-14, it is not exactly an easy process and it is very difficult to get dead nuts accurate.  Typically we finish, hope for the best and check mag drop as a confidence factor.  

  

 There are several ways to "do this better" when attempting the process, but one of the easier ways to time an engine is with the Aircraft Tool and Supply Company TIMERITE device.  This is actually the same way the Russians attempt it, but with a much more accurate instrument.  

  

 Apparent;ly the TIMERITE timing tool does not have gauge arms and scales developed for the M-14 engine, which actually is kind of odd since there are more of these engines in this country flying than there are some of the older radial engine designs that they have developed scales for. 

  

 One of the ways to influence this is simply to call these folks up, tell them that you have an M-14, and would like to see them develop their product so it can be used on YOUR engine.  Heck, it's a toll free call:  1-800-248-0638  

  

 I am not saying there are not better methods than the TIMERITE (A Laser scale comes to mind), but being able to purchase and use this instrument on M-14 engines would be of benefit to all of us.  So consider giving these folks a call sometime and tell them you'd love to see them develop their product to be used on our M-14 engines.   Can't hurt.

Called them:"So I hear your now offering a gauge arm and scale for using the Timerite on a M14P??"

A what?

Which engine?

A Russian engine?

Radial huh?

Well tech is out-- call back tomorrow...............

 



Not very encouraging.

Yep.  Me too.  Then I talked to a young lady that said they usually add new scales and arms when they get enough calls from people who own them.  They need to understand how many are out there before they will invest, which makes sense.... hence my message.  

  

 Thanks Doug!

Hi Mark

  

 Having already fabricated an arm and scale for  my TIMERITE to accommodate the Ivchenco series engines I can tell you it is  barely worth the effort.

  

 The TIMERITE is an excellent timing device but  like any other magneto timing system that utilizes piston position it  becomes increasingly less accurate as the timing specification approaches  TDC.

  

 This of course is a result of piston dwell where  the piston is stationary through an angle of  4 to 5 degs. either  side of TDC.  In that area the TIMERITE is totally useless.

  

 Having said that the M14P engine WITH the  specified fixed spark M9F magneto is good candidate for the TIMERITE since  the timing angle (and therefore the setting angle) is 23 degs.(crankshaft)  BTDC.

  

 However a few M14P's and (as far as I know) all  other variants of the Ivchenko line utilize the M9, M9-25M or M9-35M.   

 These of course are all auto advance mags and,  varying with engine model, are timed with setting angles in the area  of 10 degs. BTDC to 10 degs. ATDC and therefore must be timed by  direct reference to the crankshaft (or corresponding prop shaft)  angle.

  

 And NO, my arm and scale are not available under  any circumstance.  They were just a test for my own  personal information.  The TIMERITE is a patented, currently available  device and if ATS think there is an acceptable market they will design and  manufacture as necessary.

  

 Cheers; 

 Walt

That's an interesting discussion Walt.  Basically from what I read, you are saying in a nutshell that due to piston TDC dwell, the TIMERITE is not accurate for determining TDC, and I see that logic perfectly.  

  

 You made a comment that "a few" of the M-14P engines use the M9F mag but most others use mags with auto-advance.  That's intesting because every M-14 that I have worked on use the M9F fixed timing mags.  That includes five M-14P's, and seven M14PF's.  From that LESS than broad experiece I came to the conclusion (which could easily be wrong) that most M-14P and PF engines that came stock with the YAK-50, YAK-52, YAK-55, Sukhoi-26,29,31 series came with the M9F mag stock.  Those are the models I have direct experience with, but admittedly only one or two of each model.  I own two YAK-50's (one wrecked) with M-14P engines, one 1974 model with original engine and one 1984  model with original engine, both with M9F mags.  

  

 That said, I have heard that the mags with mechanical advance will work equally was well.  Dennis, can you add to this?  George or Cliff Coy?  What are the usual mag configurations (stock) on M-14's?  

  

 You've used this device on an M-14, and I have not.  So excuse a stupid question if I may.  If you can determine the total piston dwell by coming up to the point of no movement (Before TDC) and then where it starts to move again (after TDC), determine total number of "no movement degrees" then divide by 2, would you not get a reasonable point of accuracy for TDC?  Just wondering.  This problem has perplexed me for quite some time, as with a spinner on the aircraft, measuring prop angle is next to impossible, and even with the spinner off, the spinner backplate also adds to the problem.  I have experimented with laser measuring, with a modicum of success, but reflection from the piston often refracts and  without putting a reflector on the piston I've given up on that.  

  

 So at this point I guess my suggestion to have TIMERITE make arms and scales for the M-14 might only apply to those that use M9F mags.  

  

 Hmmm.  

  

 Thanks Walt. 

  

 Mark

Mark,

For those engines that have spinners and back plates that cover the 

timing marks on the M14, the easiest way to check or set the timing is 

to use this device available from ATS.



http://www.aircraft-tool.com/shop/detail.aspx?PRODUCT_ID=E25



Secure it to the front of the spinner and set the disc to "0" once you 

get #4 cylinder at TDC.  Works just like having the spinner off and 

seeing the timing marks on the prop flange.

The M9æ magneto with the high voltage type of shower of sparks was pretty much standard for the M14P on Yaks. The M9-35M magneto with the vibrator coil type shower of sparks was pretty much standard on the M14-V26 Kamov engines and M9B engines. Either works equally well. Most Yak 52W and 52TW had the M9-35M magnetos as new production M9æ magnetos were not available at the time and new Mp-35mš type were available.

ššššššššš I use the just a screw driver or awl to feel TDC. It is probably as accurate as the Russian gage or TIMERIGHT. If I cannot get to the propeller flange due to a spinner I use one of the šTiming Indicator TP102 Tools (Aircraft spruce 12-01187) and time it to 15 deg BTC (24 deg X .63).

No Mark that is NOT what I wrote!

  

 I wrote " A few M14P's and all other variants  of the Ivchenko line utilize the M9, M9-25M or M9-35M"

  

 And yes you have appeared to miss the point  entirely.  The TIMERITE is not a TDC indicating tool.  It is, as the name implies, a timing too.

  

 One establishes the TDC reference by simply setting  the adjustable scale to "0" after positioning the piston at the top of it's  compression stroke.  Whether the crank is precisely at "0" degs is totally  irrelevant to the process.  The TIMERITE measures piston  position relative to the TDC position of the PISTON and displays that  position as a function of crankshaft rotation.

  

 You are correct the TIMERITE is of use ONLY with  the M9F magneto.

WALT!  Sorry, if I misunderstood and missed the point entirely

  

 So, if I understand it now, most of the M-14P and PF engines came with the M9F mag, and thus the TIMERITE device will be of use to them.  Got it. 

  

 I think that was what I was trying to say from the gitgo, but.... whatever.  ..... thanks.

  

 Mags that use mechanical advance require the set timing point to be set very close to TDC, which is hard to determine with the TIMERITE due to piston dwell.  For example, a mechanical advance M9-35M mag with 35 stamped on it, would have a set point of seven degrees past top dead center of crankshaft angle, which would be difficult to determine with the TIMERITE.   Would you agree that I understand the point now?  Thanks.  

  

 The only thing I was suggesting was that the TIMERITE would be a nice thing to have on M-14 engines.  Since most M-14 engines use the M9F mag, I guess we are in agreement on that point.  

  

 So, if you have an M9F mag on an M-14 engine, please give those folks a call if you would.  It's always nice to have another option, even though it appears that the E25 timing indicator might be a better way to go.  

  

 Sorry for misreading what you wrote Walt.  It was not meant to upset you.

I think what was mean was the tool makes it possible to find TDC. I have 

one that I use all the time to find TDC and it works fine.  Had to make 

one small modification though because when the tool is screwed into the 

spark plug hole properly, the moveable section will jam or bind on the 

sleeve because of the angle between the moveable section and the 

piston.  All I did was put a VERY slight bend in the moveable section 

which changed the angle just enough to permit it to move up and down easily.

 This tool makes it possible to time the mags, regardless of model, accurately and consistently, regardless of a spinner, backing plate etc.

Yep Dennis that's the case and thank you.



I should have further stated that you need a pointer (or the Aircraft Spruce tool mentioned) along with this TDC finder.  The marki ngson the tool allow you to easily bracket the dwell at TDC.  I use a pointer as described in the Yak mx manual and have timed -9F and -35's without issue.

Hi gents



excuse me but I perhaps missed something, but why not use the TDC tool provided in the original russian tools???

Or even try to reproduce it ???

If this is a good solution????



I have one but I don't have the knowledge to use it. One day perhaps.

  

Sorry for this stupid question but ...



Thanks and best regards



Didier

There is always a hard or 

an easy way to solve a problem.



I personally prefer the easy

method and set my magneto timing

by using a chopstick, a bendable

ruler and a household elastic.



And no, I will not interfere with

the pros of the list and leave

you with that hint.



cheers

I have had 2 bad experiences with the original Russian TDC tool.  In 

each case the "hook" jammed in the horizontal position and I could not 

release it.  Twice I had to use a Dremel tool cutting wheel to cut the 

mechanism above the spark plug hole and pray the center section with the 

hook would not drop into the cylinder.  I was lucky twice.  Needless to 

say I am not going to try for 3 times.  So I refuse to use it under any 

circumstances.



The problem is the quality of the manufacturing regarding the hook and 

arm that slides in and out of the section that screws into the spark 

plug hole.   If it jams and you can't release it so the hook points 

straight up and down, your screwed.



Use at your own risk!

For those that don't want to pay the Snap On prices, here's the exact 

same tool for under $20.

Dennis,



if you put an o-ring in 

the upper part of the 

original TDC tool it

will not turn accidentally

and save you the headache.



If you like I could send

you a picture.



cheers

Thanks Elmar for the offer.   After my two experiences, I vowed to never 

use one again.

Dennis,



FWIW the one I have is the 14" which seems to clear more of the items near the cylinder making it easier to work with, and surprisingly it was within a few $ of what I could find elsewhere.  Good find on Amazon on that one!
