My thanks to both of you for the solution for using the later transmission output shaft seal plate instead of the original part which is no longer available for the LT230E model H. I should mention the original H model trans output shaft seal is also not just no longer available but is of special design and construction quite possibly manufactured just for use by Suzuki.
I was hesitant about grinding on the transmission bearing in order to fit a pilot bearing puller. My solution was to use a different style of puller found on Amazon than the one suggested but modification was required to make the puller fit into the snap ring groove on the original bearing. This quite possibly rendered the puller a single use item unless I have to use it again on another LT230E. This style of puller is sold by several sources on Amazon and from the three different style of pullers I ordered this one was the easiest to modify. Thankfully I could take advantage of free returns which Amazon Prime to return the other pullers.

After fitting the puller to the bearing, removal of the bearing from the engine case was easy without resorting any serious application of torque nor was heat required. Installation of the replacement 6206 bearing required removal of the left footpeg and reverse shift lever. This provided clear access for tapping in the new bearing. It is very important to get the new bearing started straight which make bearing installation not only easier but also minimizes damage to whatever you are pressing the bearing into. Normally it is a good idea to place the bearing in the freezer and heat the engine cases in the oven at 150'-200 degrees max but in this situation this is not possible nor necessary.
I used the original H model sprocket spacer which ended being slightly shorter than what was needed with the new bearing. To bring the sprocket out farther I used an old sprocket lock as a shim. Keep in mind the front sprocket is supposed to be raised on one side which is supposed to mount inward against the spacer. However if the sprocket is flipped, this can affect chain alignment as it will move the alignment of the sprocket inward. If using a front sprocket without this raised section, you may need to add spacers to properly align the front and rear sprockets. Also the original sprocket spacer is 40mm in diameter which is larger than 38mm found on the later and longer spacer used on subsequent models. The later version sprocket spacer is too long and Suzuki utilized a different transmission output shaft with this spacer. For proper seal fitment a 40mm ID X 52mm OD X 8mm seal should be used not the 38mm seal found on the later versions of the LT230E. Though I suppose you could force use a 38mm seal onto a 40mm shaft/ spacer. The 40mm seal is readily available but not thru Suzuki.
I hope this helps anyone else who encounters this issue of the model H transmission seal plate/ seal being no longer available. If your original seal plate is damaged or the seal goes bad this should bring some relief it is not the end of life for your early type LT230E.
