 Posted: Sun Sep 16, 2018 6:52 am Post subject: JD 1010 Timing |
  |
|
I recently installed a Pertronics electronic ignition in my 1965 JD and am having trouble getting the timing close enough to start the engine. From the previous owner I think the firing order was
"reversed", but it did run for awhile. I now have the firing order correct: 1-3-2-4 with a counterclockwise rotation of the Prestolite distributor, but cannot get it to fire. My book does not indicate
where any sort of timing marks would be. Does anyone have a suggestion?

Here's the pages from the service manual on timing the distributor. For the life of me I can't find or remember the firing order. Do some searches on this forum because I know it's on here somewhere. Hope this helps.

Firing order (1 is front of the engine) 1-3-4-2 according to http://1010series.forumotion.com/t6-specs-for-the-1010-updated-february-8-2014

Your firing order is not 1324 due to 1 and 4 being at TDC at the same moment as are 2, 3 pair but 180 from 1, 4 pair. Physically impossible to be 1324 then. 1342 is physically possible and since there is a rumor it is 1342, I'll put all my money on that one.
You might try flipping the pertronix magnet ring upside down if all else fails. My 59 chevy needed this done after several attempts failed (no fire what so ever) and I had set up a test bench away from the engine to determine the cause of the failed attempts. Turn the magnet ring upside down and it worked, right side up by instructions and it did not work. Been working perfect upside down for better than twenty years now. Sometimes the answer is not in the manual.

Thanks for your great comments. I confirm that the firing order is in fact 1-3-4-2. The photos from the manual are a a real help - at least I know where the hole for the timing mark is! When I get some more time tomorrow I'll give it another shot.

Just to make sure--you haven't had the oil pump out of the tractor have you? If you don't put that back in correctly it's impossible to get the timing right.

No, I haven't touched the oil pump. I found the timing mark and will follow the directions from your reprint to manually set the timing. Last time I tried it cranked for several seconds then backfired
through the carb starting a small fire!

While this is certainly true with the diesel version, in reality, ANY oil pump shaft orientation can be compensated for in the gas version by rearranging the location of the #1 wire in the distributor cap and/or the distributor can be rotated up to a full 360º to correct for the oil pump shaft installation and set the timing perfectly.
To the "O.P.", those timing instructions are needlessly complicated for a novice. I'm wondering if you have it time 180º "out".
With sparkplugs removed, carefully manually crank engine (ignition "OFF") with a finger OVER the #1 sparkplug hole until compression blows out past your finger. Continue to crank slowly, looking for the "TDC" mark on the flywheel.
As you pass TDC on the firing stroke, "blow" will turn to "suck".
TDC, (where you want to be) will be between the two.
Note the position of the rotor, it should be pointing towards the #1 position in the distributor cap, and the breaker points should have JUST opened.
NOTE that's when spark occurs, when the points JUST break open, ending electrical contact to ground through the points.
When you are satisfied, crank the engine 1-3/4 turns, then watch for the timing mark on the flywheel, and the opening of the points.
Once again, points should JUST begin to open at or just after TDC.
That will get timing close enough to start, then check with a timing light to get it exact.
