Hey men. Haven't been on here in awhile. I've bought a 1956 buick project. It's got the original nailhead in it. It will turn over, but slowly. I don't mean just drag over, but turns over about half the speed it should. I've tried two different batteries, cleaned and tightened all connections, etc. Last thing was to pull the starter, and get it checked. The armature was bad, and I replaced it. Thought sure that would do it, but it made very little if any difference. From all I've been reading lately, this ****er is definitely 12 volt neg ground. But it's got a battery tray, that is long enough for two batteries. Did it come out with some monster size battery or some other strange senerio. My next step, I guess, is to drag it up the road about 30 mph in low range and see if it will start that way. I really don't want to put a lot into this motor, until I get it running to see if it's worth keeping. Sorry for the length of this post, but, I wanted to be as clear as I could. thanks ronnie
The original battery size was a group 60 http://www.restorationbattery.com/g60k.html Most battery stores have a new style replacement though. Have you tried pulling all of the plugs, squirting a couple of shots of oil down each plug hole and cranking it over with the plugs out to work the oil in around the rings to help lube the rings and pistons after it has been sitting for years? that may free it up a bit.
I was just going to post the same thing. The battery size does not matter. I had a new smaller rectangle battery in my olds and then finally bought the correct sized one before selling it. The cranking amps of the battery is what you have to worry about. I would try the oil trick before getting too wrapped up in rebuilding all the electricals.
What type of trany is in it ,trans might poss be casusing your slow turning over problem I had a old 51 Chevy and the motor turned over real slow finally said screw it pulled the trans and saw it wasn't in the best shape shure enough it spun over fine after and the motor ran great (everything was froze up pilot bearing was frozen solid to the shaft turned the hole deal over Just a thought Good luck
You might try replacing the battery cables if they have any age to them. I had a '84 Ford diesel that had the same problem, and it turned out to be the problem. Corrosion under the insulation.
I removed the plugs and squirted oil in the cylenders. It spins great with the plugs out. Put the plugs back in and it seems to be turning over much better now. Thanks, mr 48 chevy.
