Precautions During running Period (Overhauled Engine) of Generator

[helper_learner]

Firstly you need a service manual to start the rebuild.

It is being done by a Generator mechanic... And i am not able to find Loncin LC3500(D)-A 's Service manual....

I am more worried regarding This;

Precautions During running Period(Overhauled Engine) of Car

Accelerating gently to mid range torque in 2nd gear and letting it overrun down back to idle abt 3 or 4 times.

Accelerating briskly on open road in 2nd gear to 60% safe engine speed and letting it overrun back to creep about 5 times,

Accelerating in burst from roll of 2nd gear to abt 80% engine rpm and letting it overrun back to creep.

This act seats the rings nicely against the bore as the cross hatch from cyls gets pushed down and ring surface loses its rough edge.

How can i do this in Generator?

[Hassan1991]

You need manual badly.
Generator works on specific rpm range due to governor and voltage controller.
If you remove both it will act as an engine and you can control the rpm. Example go karts.
But if done according to manual you wouldn't need that.

Ok... means if i adjust governer and rpm properly then there wont be any need for that... and also i can run generator on load right?

Thanks for the help
One more question, how to set the ignition timing ?

[Hassan1991]

@hassantahir2 said Timing is fix. Although mark everything before talking it off. Will make it easy to reinstall.

Your suggestion really matters

[Hassan1991]

Really sorry. Missed your post.
Prefer petrol. As cng runs hotter and dry.
In Lahore you can get in from Badamibaag.

Really sorry. Missed your post.

No need , I knew that, that's why reminded you

Prefer petrol. As cng runs hotter and dry.

How long? Currently have done 10-11 hrs on Petrol. Should i run it more? and when should be the first oil change? Mechanic recommended to run till it uses 7lts of petrol and then change the oil and switch to Gas. What do you say about that?

[Hassan1991]

Thanks.
Yes change oil slightly before time. So any kind of metal dust left inside can be drained with oil.
Switch to cng after oil change but do use petrol time and again. Valves and valve seats don't like continuous cng usage.

crucial point....adjust tappets every 150hrs running to specs....not just haath andaza...

i do that .....more precisely ..head need redo now and then (valve lapping) along with carb service

if usage is alot...i prefer keeping spares along like a 2nd head ready to go../spark plug/ oil/ AVR/ etc

Yes, i have the guage to adjust tappets...

Can you plz define "now and then" in terms of number of hours

if usage is alot...i prefer keeping spares along like a 2nd head ready to go../spark plug/ oil/ AVR/ etc

No usage is not alot only 5-6 hrs per day

Yes I have kept oil, spark plugs but not other stuff ...

I have bought Havoline® Formula SAE 10W-30 Mineral Oil After how many number of hrs do i have to change the oil, Manual suggests after every 100 hours i am a bit confused about the value...

[Hassan1991]

I'll say 80-90 hours.
So on Second oil change you can adjust the tappets.

Will do it as you said...

[SER_GTR]

SER_GTR:

as per honda....every 500hrs...you may check if needed....usually a leakdown test determine....in laymen's term.. only when you feel power losing or compression leaking ...

after initial running.....yes 80-100hrs ..but every 30hrs....check its level
