Inglis Rebuilding
WOW Paul it looks like you are doing a great job.
The transmission oil level and quality can be checked easily without taking the transmission apart by inserting a three" piece of coat hanger wire through the vent hole with the transmission sitting level. You may have to rotate the drive pulley to get the dip-stick to go all the way to the bottom of the gear case as it will hit the top of the connecting rod depending on its position. The oil should be about 1/2" deep in this area and should be a nice light color, if it is murky, brown or white it most likely has water in it. If it looks OK but is just real low you can add transmission oil to increase the level and new oil added helps rejuvenate the oil oil, do this by putting the oil to be added into an empty Zoom-Spout bottle and filling into the vent hole.
You should try to be sure that the transmission is one of the Heavy Duty ones, You can tell by looking at the bottom of the case.
On the spin tubes sometimes the bottom flange will separate and all the clutch and brake parts fall off from the bottom, if this happens it means you need a new ST, which you almost always need anyway during a rebuild.
One thing I like to do when repainting the center post is after installing the top spin tube seal is to paint any exposed metal at the top of the center post right up to the rubber seal, as this area can corrode and cause a serious failure of the whole job.
Good Luck and keep us posted on your progress, John.
