Getting ready to drop in a rebuilt230 and have a question

[Alshere59]

Well as stated . Getting ready to replace my old 218 with a 230 and was wondering of it is worth while to strip the gear drive of an old oil pump I have and prime the engine prior to hitting the key to turn it over? Seems to be the rule of thumb for many other engines.

Here is where I am at now.

did you use a quality pre assembly lube??? I turned mine over with the starter (without the coil wire connected) and within a few seconds had pressure recording on the gauge.

After the pressure showed, I reconnected the coil and fired it over, whereupon the pressure jumped to 50 + lbs when it started. Seemed to be alright looking back after about 12K miles. Still runs at 40 + lbs hot and idles at 25 hot.

Yes. The engine is prelubed. I just am used to bringing the pressure up before it is turned over Granted never worked with a Flathead before. Can't see where it would hurt to have all the oil passages full before the engine turns over. I had planned on pulling the coil wire as well even after the new pump is in place.

So has anyone tried it?

Using an old pump less the gear is a great way pump oil thru out the engine until you have an indication of oil pressure. If you do this, you probably know that when reinstalling the regular pump, the pump has to be clocked per maintenance manual. If you do not have an external set up to feed oil under pressure to prime the system, another method is remove all the spark plugs and run the starter until pressure comes up. Best to ensure oil system is working before starting.

Yep I know about the alignment/clocked. Just looking for any edge to keep it turning over. I have read a few posts of others wiping the bearings causing damage.
