Day: I'd say it'd be a good thing to check on a daily or weekly basis until the tractor has been broken in. Some locktite might aid but I wouldn't use red as the loader frame probably has to come off for certain maintenance stuff.
So, got to play on the tractor for a day since I got it back. I took all my tools to try to see what sizes I'd need for my kit. I didn't realize my socket set was so small... I didn't have anything above 17mm so I'm gonna have to pick some bigger ones up. Thanks for the info Gary, I'll be sure to swing by and take a look.
I don't have my notes with me but I tried sockets in sizes I had an I tried to measure the ones I didn't (w/ tape measure as I didn't bring a caliper so its iffy) but if I recall, I used 12, 13, 17mm and maybe one or two smaller ones and then I think I measured 22, 28, and 36mm. But don't quote me yet, thats from memory and some potentially bad measurements. Def. gonna put a crescent wrench or two in my kit as well.
Also, they moved the loader hose attach spot... its kind of strapped to the loader frame instead of the ports sticking straight out in a block. Looks neater but if I remove the loader there'd likely be hoses hanging from the frame. I'll post a pic when I can. Oh, and still seems to leak a little. Looks wet with oil but I'll have to clean it up and then work it to see if its fresh.
