Thought I'd start a thread about some genius solutions that will help everyone in here. I know there are multiple examples throughout many different threads, but perhaps we can gather them together in this thread for newbies and seasoned members to reference / check out with ease. Feel free to post / link anything that benefited your repair or restoration. 
Will start off with this one as I noticed that I'll need to replace the fan on the 1650 I started yesterday and I remembered seeing this before. Don't know how many have seen this guy, he's got plenty of videos on YouTube, including the foot control for the hydrostatic drive...but this is a good, simple fix to replace the cooling fan without having to take apart the drive line.
Kraig, thought this section would be appropriate. Move to the correct section if better suited elsewhere...
