debshirl Posted May 21, 2006 Posted May 21, 2006 just bought a 19d engine at portland for parts stock.after looking at manual looks like bore and stroke are the same as a 23d engine. what was this engine used in? and what year? are parts interchangeable?
MPH Posted May 21, 2006 Posted May 21, 2006 19D's were used in the 725's and B-1's and could be used in the 700 wonderboys or wards squire also. Thier gettin' kinda like hens teeth, if it's complete you may make out good selling it complete.
Roy Posted May 21, 2006 Posted May 21, 2006 Don't have my Briggs manual handy but I thought a Model 19 was 19 CI (cubic inches) and a Model 23 was 23 CI. Also think anything larger than a Model 19 is taller which requires a frame cutout for the blower housing in the FDT's.
PatRarick Posted May 21, 2006 Posted May 21, 2006 Bore is the same as a 23, but it has a shorter stroke, thus the 19 cu in displacement. Pat
HubbardRA Posted May 22, 2006 Posted May 22, 2006 Installation of a larger engine can be done in a FDT without the frame cut. An example is my 61 Wards. It has had the original engine, a 10 Hp B/S, a 12 Hp Kohler, and now a 14 Hp Kohler, and still I have not made the cut in the frame. It is solid, one piece. It requires a little work with a hammer, but other engines will fit.
johnmonkey Posted May 22, 2006 Posted May 22, 2006 I have a 19d in my 1963 gardenmark squire. It needs a new point plunger. If I do anything to it, I may put in the electronic ignition (I think its called a magnetron),(the one where you have to get the flywheel re-polarized). Jh
HubbardRA Posted May 22, 2006 Posted May 22, 2006 At the time I installed the first larger engine in my 61 Wards, I had never heard of this site. Instead of cutting a notch out of the frame, I used a large ball-peen hammer to form a clearance area in the frame. This gave most of the clearance needed for the engine shroud. I had to put a very small flat spot on the corner of the fan shroud to give the additional clearance. If I had a template at the time, I most likely would have created a factory type cut-out in the frame. There are more ways than one to solve a problem.

Roy, the actual difference is that between the mounting base of the engine and the center of the crankshaft. The 19 in the 700, 725, and B-1 has two 3/8" flat bars that are used as spacers to raise the engine so the crankshaft is at the same height as the larger engines. Without those spacers, the frame would have to be cut out or modified for the 19 as it is with the larger engines. Why this was done with those models of tractors is curious to me, since the 19 was the only engine available for them. The larger engines sit at the proper height without the spacers. One theory is that perhaps those tractors were originally designed for the model 23, but for some reason Simplicity decided to go with the model 19 instead. What makes that theory unlikely is that there is no cutout in the frame which would be required (or modified as Rod states)if the model 23 is installed. Pat
