Other Slow Speed Diesels / Resurrection of a Deutz MAH 914, 1952? THE GERMAN GENTLE
« on: March 27, 2023, 07:23:25 PM »
Gentles,

A few more bits and tweaks.

1 - Big end torqued at 140NM; And oil pump by eyeball!

2 - IP tappet got also serial number;

3 - tin prove to get TDC bump clearence;

4 - tin smashed by piston at TDC;

5 - measuring clearance;

6 - Torque head nuts at 170NM... by now! [it has 3,6mm of clearance, therefore low compression, and I think this is why it need zundfix starting cigarettes]

Other Slow Speed Diesels / Resurrection of a Deutz MAH 914, 1952? Lets see! SOME MATH TO THE GERMAN
« on: March 15, 2023, 11:51:47 PM »
Gentles.

Because head got slight skim, now I got to do some math to confirm travel of valve stems.

Pay some atention do this pic: https://listerengine.com/smf/index.php?action=dlattach;topic=9555.0;attach=7412;image;

As you can see Cam lobe has 8mm profile, therefore got to extend measure to rocker arm, to get max travel of valve stem, and math says it will be max 13mm.

See pic!

Cheers
VP

PS: Late night putting things together, to avoid breaking bits one against others.

Today got head from VEICOMER (https://veicomer.com/en/);

New bronze valve guides, milled surface, and top valve stems.

Now prepare all to put the German snoring.

A special thanks to Mr. Pedro, the VEICOMER's owner - as you can see he's also a man with hands on job, on top of running all the show at shop.

A few pics to the show.

Other Slow Speed Diesels / Resurrection of a Deutz MAH 914, 1952? ROD AND PISTON IN PLACE

After a work day nothing else better than some yoga by the German.

Give some heat to piston with hot air gun... and voilá pin slipped like butter. well not quite!  ;D ;D ;D

I put all piston rings aligned at 180º from each (with gap by OD of pin), and oil ring by the pin to avoid any force on the ring tips. (Please tell if this is the right way).

Snug large end and give a few rotation and take cap out to see if everything was ok. put back cap.

Made a small oil sump (brake spray cap) and fill with oil, and give several rotation to crank, to put pressure at oil pump. As you can see it drips nicely.

Piston course at honed liner looks sweet!

Things look to come together.

A few pics for the audience.

Other Slow Speed Diesels / Resurrection of a Deutz MAH 914, 1952? GOLD PRICE SPRING
« on: February 22, 2023, 09:30:54 PM »
Cobba, Gentes

One more bit. Governor lever spring - ONE of 2.

One was lost, and the other came at gold price.

Take a look at date of order and my patience to let them search for other spring.

After all its not only the engine that is tricky, some suppliers too!  ;D ;D ;D

2 pics for the show.

Other Slow Speed Diesels / Resurrection of a Deutz MAH 914, 1952? THE BIG STUFF

Cobba, Gentles

Yes the liner has some callus, but nothing that takes my sleep.

My toys are only to showoff!

the previous pic of crank where only to show how many stamps the put at crank to say it was good to go.

Today put oil seals in crank bearings cover, and first got to make the jig with a pipe cut and open. Got to press them in.

Cut gaskets for covers and fit in place with 1 side sealant.

After that clean crank from all dust, roller bearing and ball bearing.

Some pic to the show.

Cheers
VP

PS: New oil seal  seats end up being a nice job, so as the bushing in crank for them.

Other Slow Speed Diesels / Resurrection of a Deutz MAH 914, 1952? MORE BITS OUT OF BASKET
« on: February 20, 2023, 11:44:12 PM »
Gentles,

Start to sort bits out of basket.

Liner receive angle grinder with diamond disc of floor tiles to clean lime stone. a nice clean after with sand paper disc, and a coat of paint (temp resistant). no pics ... forgot!

Cleaned ball bearing of main, it got very dust and some debris from lathe at shop.

A few pics of shop mesures (a special request from me to machinist) of liner and piston to see how worn thing are, and ask to slightly hone the liner.

Big end was also honed and rod got new smal end bush, and big end ajusted to crank.

A few pics with mesures and stamps at crank.

Cheers
