Hi,

 

Just completing my 800hr operation and 5 year rubber replacement. Last time I did this I had easy access to a nice compressor with good regulator (to get the pressure down to below 15 psi) to do the PURGE.

 

Accessing a compressor is now more problematic SOooo I thought (dangerous) is there a way to ensure complete uninterrupted oil circulation within 912 ULS after complete oil removal due to replacement of hoses & filter.

 

This is what I have done:

 

After replacement of all oil lines/hoses & oil filter -

 

Partially filled (not much) new filter with fresh oil before installing

 

I put 2 litres of oil in the crankcase, via crankcase to tank return line (& funnel)

 

Put as much oil as would gravity feed down tank to pump line (may be 200 ml). Took quite a while with much massaging/squeezing of lines for all air to escape.

 

Put remainder of oil in tank - only just showing on dipstick.

 

Left to settle overnight.

 

(Total oil removed 3 litres)

 

Total oil added 3 litres

 

"

 

Sloooowly turned over engine - started to get "THE GIRGLE within about 6 compressions. Continued to slow turn 20 + full revolutions (each compression producing the expected flatulence).

 

Checked oil level in tank - just below MAX - added 100ml to make up (probably filter capacity).

 

I have not started engine.

 

Question is - have I done enough to ensure oil circulation 100% complete with no air bubbles preventing adequate lubrication to some vital part?

 

OR

 

Should I go get that pesky compressore and DO THE PURGE??

Follow up - dont have the nerve to start the engine without doing the recommended PURGE. Went & got the compressor turned down the pressure to below 15 psi. Did the purge. All good. Engine running like a "sowing machine"
