Hi Ian

First things first. put pictures as many as you can!

Shims: My 914 has 3*0,25mm (only after running you can identify the knock - the few more knocking aka too early, the more lacking of power)

Dumping fuel: with injector out, turn crank to TDC (You can put a comparator with stem in bore to measure distance versus fly angle) [couldnt find angle of fire Before TDC]. YOU CAN DO IT WITH VEGETAL OIL FIRST.

Steel washer? where?

Just my thoughts for now.

Cheers

My injection pump had a steel washer along with shims behind it but the ring was badly bent and the shim paper falling apart.

Does your pump only have the 3*0.25mm shims between it and the face it mounts on? My flywheel has an F stamped on the rim indicating TDC and the manual states the injection point should be 15 degrees +/- 1 degree.


I'll get some pictures on here soon! This one is staying the natural patina so don't expect flashy paint jobs!

Re: Resurrection of a Deutz MAH 914, 1952? Lets see! IP of MAH 914/916

Hi Ian, Gentles

Lets see the IP cam lobe bump: go here: https://listerengine.com/smf/index.php?topic=9555.msg109890#msg109890

As you can see lobe lift is 10mm. Therefore (now go here: https://listerengine.com/smf/index.php?topic=9555.msg109994#msg109994)

You must see if the travel of plunger is too far (you can take off IP valve [with IP snugged in place] and with the comparator see how much the travel is). If no shims you can eventualy damage pump element and plunger.

And yes all shims are between IP tappet guide face and IP face. Caspici?

I put back all paper shims it had, but if I notice it must be fine tweaked ill make more of 0,25mm gasket paper.

About fancy painting it's just a matter of each country evaluation. Here if I present an engine restored with patina is only a piece of junk.

Remember those engines are low compression, therefore they need starter cigar.

Cheers
VP

Resurrection of a Deutz MAH 914, 1952? Lets see! READY TO RALLY
« Reply #259 on: June 29, 2023, 10:41:10 PM »
Gentles

Next last weekend of July we have the anual craft, culture, and heritage fair at village, therefore I have no time to put the "decent" fuel tank on the German.

So I spoke with chinese and they sent another 1L tank to put on to make the rally.

Take a look how it fits nicely.

2 pics for the show.

Cheers

Hope your festival goes well. I would consider a paint job on the plastic tank o make it look as if it is metal or same as th engine. You have done a wonderful job on your German and has been a pleasure to follow the progress and the dedication to making it perfect again. Well done  VP!

Resurrection of a Deutz MAH 914, 1952? Lets see! ULTIMATE PREPS
« Reply #261 on: July 02, 2023, 03:29:14 PM »
Gentles

As usual first word will be addressed to all members of LEF, that are with me since the beginning, a special thanks.

Some steps back were supported for them, as you all said thing are always this way, and I must embrace things as they show and give my personal touch in order to achieve my goal (this one is for you Bob, with a special hug).

Cobba, another hug for you, just because you can see the aim of my tasks, and comprehend the world is not square. And no, the 1L tank will stay as it is.

Willw, thanks for your appreciation.

Stef, you still want I present a restoration of a Famel Zündapp, isn't it? Forget, its too expensive!

Butch, look at my German, its fancy, isnt it?

Joks done. Lets go to the business!

Gave a long run to the German (+20mn), let it burn till water gets hot, tweaked governor to 1000 rpm - and no leaks. Open crankcase to see if all is ok, and it shows a nice chamber.

See vid here: https://youtu.be/kJzUZHobpiY

Cut elbow from hopper lid and extract remains of iron from threads with high amp weld rod, and handle saw. New paint, and voilá!

Some pics of process.Forgot to make some pics, but you will all understand.

Cheers
VP

+1 Cobbadog, what a beauty! I don`t mind the new fuel tank, it would look better with an original tank but I doubt anyone could supply one. So the best option is for something functional but clearly not original.
I hope the visitors to your festival appreciate how much work, money, talent and effort went into restoring your engine, it is a credit to you, your family and your community. Well done VP

Bob

Re: Resurrection of a Deutz MAH 914, 1952? Trolley king pin
« Reply #264 on: September 21, 2023, 12:57:20 AM »
Gentles,

Slowly back on track, Im assembling The German trolley.

Today manage to assemble the king pin, it ends up to be a expensive bit because machinist labour is expensive.

It's perfect, just as I had designed.

Take a look.

Cheers
VP

PS: Bob answer please to my question at my Petter thread.

VP, once again your attention to detail is at the top end of perfection and fitting to the quality finish on "The German". Your king pin design is exceptional so much so I will not post what I recently did on a transporter only a description. 2 flat 5mm plates greased in the middle and a 20mm bolt through the lot from axle to cross member of the trolley.
If a pic is required unfortunately cannot obliged because we are on an extended holiday in our caravan until near Christmas. No pics of the toys with me, sorry.

Gentles, Cobba

A few more pics of the king pin and axle pivoting with silent block.

Primary paint done.

Silent block is a bit of radiator hose 18mm OD, and 12mm ID. Enjoy!

Cheers
VP

PS: managing to twist the 2 iron bars 40mm*6mm, to attach the pull bar.

Re: Resurrection of a Deutz MAH 914, 1952? THINGS GETTING BETTER...
« Reply #269 on: December 03, 2023, 11:15:10 PM »
Hi Gentles

Liver issues are getting better, therefore German trolley got a few more tweaks.

King pin is done - Lets see if it hangs all the load or it needs reinforcement.

Today manage to set the rear axcel, it will have a set of silent blocks.

Got to go back to the design sheet in order to alter the anchoring of the axcel suport.

A few pics to joy.
1 - seeing clearance to floor with level.
2 - detail of 2 pair of silent blocks.
3 - adding height to reach level.
4 - kart leveled and height seated.

Cheers
VP
