[AT] John Deere Projects UPDATES

[partzpicker]

Carl, do you think the clutch discs are getting that hot or could it be that the ventilator pump is malfunctioning and it's blow-by coming out through the clutch?Sent from my Sprint Samsung Galaxy Phone.

That’s probably why the cracks and why the nut is beat up. Do you know what it was hitting against? I’d take a good look and see what it was hitting to make sure nothing else is damaged.Probably explains the clutch burning also.Carl----- Original Message -----From: STEVE ALLEN <steveallen855 at centurytel.net>To: at at lists.antique-tractor.comSent: Thu, 18 Jun 2020 20:08:07 -0400 (EDT)Subject: [AT] John Deere Projects UPDATESWell, gents, I have another update in the long saga.Let's begin with the '51 A.  I acquired a mesh nozzle to go over the inlet of the sediment bowl so that I could pull the lawnmower tank off the side (I was afraid of catching it on a tree limb while working) until we can pull the tank to clean it right.  It is a tall, fine mesh that keeps the crud out, and, when we used the tractor, it worked very well:  plenty of gas, no clogging the inlet.  Not the permanent solution but a workable one.  Tractor did a great job finishing up the brush-hogging.  I still need to replace the points.Now, the '49 A.  I thought I had bought a set of points for it, but I was wrong.  I did get a cap, however, and, after cleaning up the old points as well as I could and replacing the gap, we had a good spark.  The old boy cranked up on the third or fourth revolution.  Spiffy!We pulled it out to run it some, and it seemed that there was a hammering in the engine.  There has always been a sensation of that, but it seemed obviously more apparent to me.  We did just a little work, but it seemed to be getting worse.  Also, the clutch was smoking when  it was disengaged.  No slipping, no noise, and it snapped in and out just fine, but, when disengaged, it smoked.  So we parked it.  Today, I had my son pull the flywheel cover off today, and we discovered the hammering problem (at least I'll bet):  Two cracks.  If the pic comes through, you should be able to see them near the lower, right nut.  there is obvious displacement of the casting, so I'll bet that puppy is loose on there.So now we need to change the flywheel.  Fortunately, I have one.  We just need to figure out how to handle it (and also to set it in place correctly).Briefly on the '47 B:  We need to test the starter and reinstall.  The generator is probably no good, so we'll just disconnect it.  I want to put good batt cables on it.  We'll probably work on it as we prepare to replace the flywheel on the '49.It's always somethin', ain't it?The "original" Steve Allen_______________________________________________AT mailing listAT at lists.antique-tractor.comhttp://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com
