300 U Points Removal???


[ Expand ] [ View Replies ] [ Add a Reply ] [ Return to Forum ]

Posted by Bob Kirk on October 20, 2008 at 12:08:54 from (74.47.219.207):

My trusty '55 IH 300 U suddenly wouldn't fire the other day after running fine a couple weeks before. I've been going thru things (first time in 7 years!!!) and have hit a wall.

Can't figure out how to remove the old points. My owner's manual says nothing about it. My distributor has a little threaded pin running thru a plastic block on the outside where two wires attach with a nut and a plastic block on the inside where the points spring slips in behind the thin head of the pin. That spring is under the head very tight, even when the nut is loose. I tried tapping the threaded pin toward the distributor shaft to free the spring, but no budge. Before I start getting physical thought maybe I should ask someone who knows.

Could you please explain the points removal steps to me?

Also, any suggestions for getting the new points up on the top of the cam lobe by removing plugs and turning the crank somehow by hand? Punching the starter seems to want to stop it with the points closed every time.

Thanks for your help. Bob

Today's Featured Article - Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract. ... [Read Article]
