Ok I decided to wing it and just Dive in. Once you get the wheel off it’s apparent what to do and everything is fairly easy to get to. This is the order I went.Drain hydraulic fluid, remove the drive belt off the transmission pulley, loosen hose clamp at the hydraulic reservoir, remove both steel hydraulic lines, unhook the 2 linkages, place a jack under transmission remove 9 mounting bolts and lower it down while you wiggle back an forth to get the hose off the hydraulic reservoir. Once it’s out remove the pulley nut and pull the fan blade off and then use a jaw puller to remove the pulley. I used a 2 jaw and it worked great. Then just simply pop out the old plug and tap in the new improved plug John Deere part number MIU14382 $6.80. Then reassemble in reverse and refill the hydraulic reservoir. I changed both filters so it took 5 qts. to fill it up. It took me about 3 hours from start to finish including test drives and shop clean up. Pretty simple job with the use of just common tools and a 2 jaw puller.
