rimontaggio motore Mp600 del 74

[Aponecasarsa]

Buongiorno a tutti,
Scrivo questo nuovo argomento anche dopo aver trovato delle risposte esaurienti su questo sito.
Ho appena fatto rifare il motore dopo una bella fumata blu continua dallo scarico a causa del paraolio lato frizione andato.
Sono riuscito a smontare il motore quasi tranquillamente, basta avere pazienza ed essere un po' contorsionisti.
Ora devo rimontarlo sul telaio, il meccanico a cui ho fatto fare il lavoro del banco mi ha detto di rimontare i semiassi PRIMA di installare il motore al telaio e poi con l'aiuto di un altra persona si riesce a montare il tutto con il pianale montato.
In questo forum ho trovato una risposta opposta, si montano i semiassi a motore montato.
Qualcuno sa dirmi qual è la risposta corretta?

Grazie mille in anticipo per i consigli e risposte

Install the left driveshaft into the differential then install the motor with the driveshaft facing the wheel hub. The right driveshaft can then be installed and there's more room to see what you're doing on that side of the engine.
When built at the factory the engine with both driveshafts would have been installed first and then both suspension units attached later on the production line - Ken

Installare l'albero a sinistra per il differenziale quindi installare il motore con l'albero di fronte al mozzo della ruota. L'albero di trasmissione a destra può quindi essere installato e non c'è più spazio per vedere che cosa si sta facendo su quel lato del motore.
Quando costruita in fabbrica il motore con entrambe semiassi sarebbe stato installato e poi entrambe le unità di sospensione attaccato successivamente sulla linea di produzione - Ken

Diverse procedure di motore, ma di installazione sono gli stessi

Many thanks in advance for your response and advices.
So, If i understood your reply :
1) I assembly engine+ left driveshaft
2) Install engine into the frame
3)Connect the left driveshaft with its whell hub
4) Assembly the right driveshaft because I Have more space than left side.
Is it correct?

Many thanks

Although it can be done there's no room to see if you install the left driveshaft later. Tricks to doing it but far easier on the right side - just don't pinch the cuffia. If you need help just ask - you have the directions correct - Ken

Hello!
Yesterday evening, I put the engine into the frame!
I follow your advice about the preassembly the engine.
Only ten minutes for positioning the engine, But 1 h for connect the right shaft with the engine.
I've also a little advice :
In order to simply the install the shafts, I compressed the suspension close its top end.
So I've more space for move the shafts and reduce the angular position with the engine.

Many thanks for your help!

I did forget to tell you that I set the suspension up on jacks which makes it far easier but you figured that out which is good - a clamp works as well - Ken

far easier if I'm there to show you

The first Step of rebuilt my @p0ne:-)

[kjjohnson]

did you paint the engine bay when the motor was out? Ken

[Aponecasarsa]

Yes, but i didn't disconnect it From the frame.
I've only Clean it and i add another new layer of the paint:).

Calm down - Calmati

Did you do anything that would have affected the timing? Re-set at TDC, make sure you have the proper points gap and that there's spark going to the spark plug. Use a brand new B7HS NGK spark plug in the engine. When everything is dry lift the choke and turn the key to 'start' and turn the engine over in short bursts. Make sure the carburetor isn't still flooded. It will be something simple. - Ken - https://www.youtube.com/watch?v=M0z1TTj ... 9w&index=1 -

Yes, i read with High attention the service manual in order to have the right timing.
Look the pictures.
When i put the rod in the flywheel, the puntine (i don't know the english traslation) beggining open.
Is it correct?
The engine rotate clokewise wiew in front of flywheel.
Tomorrow, I'll try your advices.

Use a test light to determine that the points are just beginning to open at TDC. If the engine backfired you're 180 degrees off where it should be. Ken
