Guest mena Posted November 20, 2009 Share Posted November 20, 2009 help pleaseI am setting the valve timing on my 25 chandler 6 cyl. when I align the timing marks on the two gears, the piston is not at TDC. I have never seen this before is this normal thxMena Link to comment Share on other sites More sharing options...
Guest mena Posted November 21, 2009 Share Posted November 21, 2009 i mis spoke. The piston is at TDC but on the exhaust stroke not the compression stroke. does anyone know if that is the way that chandler designed it Link to comment Share on other sites More sharing options...
Seldenguy Posted November 21, 2009 Share Posted November 21, 2009 Mena- I Think you may get an answer to your question if you posted on the Chandler site further down on this forum. The Chandler folks are very helpful. --Bob Link to comment Share on other sites More sharing options...

56Roadmaster Posted November 21, 2009 Share Posted November 21, 2009 I would ask which piston are you referring to? In a six cylinder there will always be two pistons in the same position due to the crank shaft arrangement. So one will be on the exhaust stroke TDC while the other is on the power stroke TDC. So you just make sure you are timed off the piston on power stroke. (You could just as easily set the timing marks 180 degrees from where they are now and wire the spark plugs accordingly from the piston on the power stroke and the engine will run just the same.) Also what you think is number 1 may be considered #6 by the manufacturer. At any rate if you align the marks as is you just wire the mageto or the distributor according to the firing order starting with the cylinder on TDC for the power stroke. This is engine 101.

Ivan Saxton Posted November 22, 2009 Share Posted November 22, 2009 To set the valve timing on 1925 Chandler, which would be 32-A or 33, set exhaust valve clearance at 4thou. (#1 Cylinder). This valve should be just closed with six teeth on the flywheel after the mark D.C.-1-6 past the indicator in the flywheel housing. Then reset clearance to 6thou exhaust, 4thou inlet. It would be interesting to know the other valve timing points, but you might guess that Chandler had reasonable valve overlap for the era. Link to comment Share on other sites More sharing options...
Guest B1rdman Posted November 22, 2009 Share Posted November 22, 2009 Not a problem in my mind.the compression and the exaust stroke will both be to tdc, piston upthe cam turns 1 revolution to ever 2 of the crank shaft.just be sure when the dist is set that it points to number one when it isat the top of stroke tdc, turn engine 1 revolutio and you should have allvalves on number 1 closed and piston at the top--tdc set dist to point at number 1 Link to comment Share on other sites More sharing options...
