Hi Guys,  

   

I am about to start my rebuilt O-200 for the first time. The Overhaul Manual calls for “Pre-oil the lubrication system using an external pre-oiling pressure system”. I don’t have one. What is the best way to ensure I have oil pressure if the motor magically starts on the first key?  

   

Cheers

Peter,

  

 Do you have an oil filter on the  motor?

 I unscrewed the filter and pumped oil into the  center hole of the filter adaptor.  Unless the oil pump is primed (the  above procedure will prime the pump) there is a large chance you will not get  oil pressure.

 I removed the top spark plugs and  then used the starter to turn the engine over until oil  pressure was indicated.  Put the plugs in and you are good to  go.

Prime the oil pump and turn it to pressurize the system. I don't know how to do this on your particular engine.

Floyd,  

   

Did you actually “pump” oil into the center hole or just fill it with an oil can? (If you pumped, did you make up a pump of some sort?)  

   

I have fitted the oil filter adapter so I could get some oil into the oil pump that way.  

   

Thanks  

   

Peter

Hello Peter:

  

 We went through this a couple of months ago when we  overhauled the Cont. C-145 engine in our flying club 1958 Cessna 172.  Go  to www.eaa163.com click on flying club  link.

  

 A C-145 is a early version of the O-300 which is  really a O-200 with two more cylinders.  The cyls. and many parts are  identical.

  

 I have a Franklin engine OH manual which says that  if you don't have the "pressure pre-oil system" then you remove the top spark  plugs and manually turn the engine over via the prop 200 revs.

  

 We tried that on the C-145 and were unsuccessful in  getting oil pressure to show.  It may work on your O-200.  Do you have  a tube type oil pressure gauge that senses oil pressure from the engine clear up  to the instrument?  Do you have an electric starter?

  

 We apparently were not able to get the oil pump to  prime by turning the prop by hand.  We used the electric starter to spin  the engine (spark plugs removed).  This finally primed the pump and we had  oil pressure indications.

  

 We have a oil filter adapter, but we did not have  the advice that you could prime the oil pump back through the filter  adapter.

  

 There are three other places to get evidence that  the pump is primed and oil is pumping through the engine.

  

 1.  If you have the tube type oil pressure  gauge, disconnect the oil pressure instrument line where it connects to the  firewall bulkhead fitting.  When the oil pump starts pumping, oil will  squirt out there.

  

 2.  Face the front of the engine, look at the  engine case on either side of the crank prop flange.  On both the left and  right, there is a pipe plug on the front of the engine case.  These plugs  "plug" the front end of the main oil galleries.  Loosen, preferable the  left plug facing the prop flange, and when oil pressure comes up, oil will come  out around this plug.

  

 3.  Remove the Rocker arm cover of a front  cylinder, when oil pressure comes up, it will travel through the hollow push  rods and drip around the rocker shaft, etc.

  

 On our C-145, we used the oil pressure gauge tube  and the front galley plug.  We already had all the baffles installed making  it difficult to remove a valve cover.

  

 Spinning the engine (spark plugs removed) with the  electric starter, it didn't take long before oil was spurting out the oil  pressure tube, and around the front gallery plug.  Both were tightened and  we spun the engine once more and oil pressure was indicated on the oil pressure  gauge.  We had a short meeting on whether there was any reason NOT to start  the engine.  Couldn't think of a thing.  So we fired it off and it's  run perfectly for over a hundred flight hours so far.

  

 We also have a first issue Cessna 150 (1959) which  is currently in my back yard with a newly OH O-200 hanging on it.  It's not  ready for sartup yet, but when we do, we will use the above system for  pre-oiling.

  

 Let us know how this works out for  you.

  

 Regards,

  

 Randy, Las Vegas

Peter,

 I used a Harbor Freight hand pump ( about $5.00)  but I believe if you stick a tube into the oil filter adapter and pour the oil  in it should work.  You just need to get some oil to the pump.  You  are only putting oil to the pump which is about 5 inches from the oil filter so  not much oil is required.  The engine should have been put together with  lubrication on the internal parts.

Thanks Guys (and Gals).  

   

I feel a lot better about the start up now. I did find something on the net from Fram Filters about priming the oil pump.  

   

I did use a lot of lube when I rebuilt the engine so nothing should be dry.  

   

I’ll let you know how it goes.  

   

Cheers

When I was an A&P in training, the guy who trained me had me lubricate all the 

engine bearings with Lubriplate during assembly. He stated we were doing this 

to provide lubricant before the oil system kicked in, and in case we never 

built oil pressure. 



We (I) have never had a problem as a result of this procedure, although we 

never happened to have an oil system that did not built pressure. It is a 

critical time, and it is important to monitor the oil pressure very closely.

Hi Guys,   

   

I made up a pressure oiler and fed it into the pressure gauge outlet. I have oil coming out of both the front oil gallery plugs so looks like were good to go. If the weather is OK tomorrow I’ll see if she starts (and has some good oil pressure readings!).  

   

Thanks

I used a pressure can set up. I took a plug out I knew was open to oil galleys. I attached a hose from can and used regulator on air hose to pressurize can until  the oil flowed. I kept adding pressure [no more than 25 lbs util panel guage read 10 lbs. I left it like this a while then turned prop some hoping to get oil smoothed across bearings. When I started it had pressure in 3 seconds. It worked. This was suggested by old guy who worked on military equpment in Korean war including small planes. dennis

Spinning up the engine with the plugs removed is a procedure that is 

referenced in AC65-12A.  This procedure also clears excess oil and 

preservatives out of the cylinder.  Make sure to ground the magnetos or 

plug wires or the mag coil can be damaged.  The engine will slow down 

quite a bit when the oil pump starts pumping oil.  During engine buildup 

there is no such thing as too much oil!

Hi Guys,



I managed a milestone today in starting the engine for the first time. I

made up a pressure oiler and pressurised the system through the oil pressure

gauge output fitting. I also primed the oil pump through the filter housing.



A couple of turns and she was away. Pressure was up in seconds and managed

to get to 40 psi at around 1300rpm.



Not quite as smooth as the Corvair but all is good to go.



Cheers
