Topic: Engine lubrication advice please...

[casperdog]

Hi..Need some advice please... on the best way to make sure i've got oil to critical parts of the engine while i'm turning it over manually.
Just bought a Cb750k5 for restoration. Cleaned carbs (what a job that was..!), oil and filter, look inside bores with scope, new plugs, new battery and ready for its first attempt at starting it.
No spark..or a VERY weak one...
So don't want to damage my engine while i'm trying to sort a spark.
The sump is now dry due to oil change.
I'm going to feed some to the cam through tappet covers...
Is it worth feeding some oil through the port next to points cover....where does this go? mains....big ends?
Any other places i can feed oil into the engine?
The motor does turn over freely but hasn't been run for a LONG time.
Any advice gratefully received...
Cheers
Phil

Thru the tappet covers is fine.
Turn it with the kick starter. 
Once it starts, the oil pressure light should go out in seconds.

Hi....thanks for reply.
How much oil should i feed through the covers. Was just thinking of a few squirts from the oil can to keep the cam lubed.
Will it drain through to the sump from here? Is it worth pouring a couple of pints in here if so?
It may take me some time to get the sparking sorted so will be turned over quite a bit with the kickstart.
cheers

you certainly dont want to go too far above the max refill volume.

Think 2Q in the oil tank, and the third Q throughout the top.
That'll keep it wet up top and pressurize the system faster.

What Flybox1 said.  You can add 1/2 qt each to the left side and right rear tappet covers.  I would kick it over quite a bit before starting.  You need to fill the oil filter housing before oil gets pumped into the oil passages

 I've added oil through the oil galley next to the points cover with good results. I've used an auto Air Conditioner oil cylinder to pressurize the engine oil system before starting. I've also just spun it over and it pumped right up.

A new set of plug caps may fix your weak spark if all else is, points condensers, coils etc are ok. On an old bike it would be prudent to change them anyway.

plugs out also while getting pressure up , it's also a very good idea to burp the oil pump . remove the pump and immerse it in oil and spin it until the air bubbles stop. While the pump is out get this kit , well worth it .

ps - don't expect any positive feedback from the seller.Very odd

i used a battery drill..to rotate the engine..vith sparkplugs aut..and primed in the oil pressure kontakt hole..but it are easyer job on a 550..vith vetsump

what oil do you guys recommend for this purpose?
 

[johans]

Hi, thanks for all the advice, its much appreciated.
Based on all the info given I think i've decided what i'm going to do.
Drain the (new) oil from the tank / sump and leave the sump plug out.
Feed the oil through all the tappet covers and side port and allow to drain from sump.
Hopefully this will bathe as much of the internals as possible with clean oil. And act as a flush.
Then fit the sump plug and re-fill as suggested with a couple of pints through the top to drain into the sump.
Does this sound like a good plan?....All your advice is greatly received by a relative amateur!
As per original post, the main reason i asked for advice is to prevent damage to internals while i'm kicking over the engine while testing for a spark..but i suppose its all good practice for first start up anyway.
Thanks for all your replies

1Q up top
1Q in the sump plug
1Q in the bag

....what is keeping you from just starting it?

Hi Flybox....
Its not sparking.....i did mention that 
Cheers

[flybox1]

yeah, i got that     but, you should be over here...

its a good way to work thru the electrical system...which will identify things that may be your cause.

post your results when done.

Plug caps should be tested as well.  Anything over 7kohms should be replaced.

Hi, thanks for all the input.
Managed to get a spark... (Cleaned up points faces and set with proper gap, and new plug caps)
Re-filled with half the oil through tappet covers and half in the tank.
Turned over with kill switch on and oil light went out after a couple of seconds. Then fired up straight away with kill switch off.....Happy days. I've only run it at tickover so far but sounds good with no obvious nasty noises.

One last question on this subject please...
Whats the best way to visually check for good oil flow?
What sort of oil flow should i see through tappet covers and in the tank?
I removed a couple of covers and i could see oil moving there but would have expected it to spew out... any thoughts?
Going to get a gauge i think..
Cheers
Phil

[flybox1]

thru the tappet holes you wont see much 'flow' but you should see a fair amount of oil being tossed around.
if you look in the tank, you should see a slow roll of oil..

[casperdog]

Ok....thanks for all the advice
