Hello everyone * I recently bought a 1973 1816 that appeared to be decent when I got it but turned out it should really have a major go through before used. It seems to have great potential...but like I said, really needs a good go through! * I am new to machinery and learning about hydraulics. I was wondering if the drive motors and the "control box" and pumps (sorry if some wrong terms) are the types of thing that basically either work or do not work? In other words, does their performance have a slow decline and should I rebuild or replace them? * I plan to pretty much disassemble everything clean stuff in parts washer and replace all hoses, bearings, etc. As mentioned above, if I have all the pumps and motors out, I would rather do the right thing and replace/rebuild if those items have a slow performance decline. * I need to hand clean the grease, grime, and manure from the bottom. I gave up trying to pressure washer it out. * I am repowering with a small Kohler water-cooled diesel. I did all the measures and it looks like it will fit with not too much modification to the rear access door. * Thanks much (tried to make paragraphs but this squished it all together?)

I've had two 1816s over the past several years. They're very handy machines, originally designed to be small enough to drive through a standard doorway. I am by no means an expert in hydraulics, but my understanding is that the pumps and motors either work, or they don't. As the system fails, there will be a period of time of reduced performance, but it is relatively brief. You can get a preview by pulling the hydraulic filter, and cutting it open or carefully pouring out the oil that remains in it. As long as you don't see metal --the dreaded golden shower -- you're generally okay. The repower idea is great. The original single cylinder gas engines are loud and shake like crazy. The only good thing about them is that they were used in all sorts of lawn tractors and other equipment, so there are old parts readily available.

thanks. I suppose I will lean towards just cleaning stuff good and making sure that nuts and bolts are tight all around. The chains and sprockets look okay. I suppose if there is no play in the axles than I shouldn't worry about bearings at the moment.

See if you can pick up a few spare axles. They do let go every now and then, and they're very hard to find.
