Well - it just happened to me. First oil change on my new (old) ca 198X B7100. PIA btw - not at all as easy as it looks on YouTube. Frame/loader is different, engine enclosure had to be removed to access the oil filter - obviously a loooong time since its last removal - gotta figure out how to mod the enclosure for easier access...
Anway, finally got it drained and a new filter in place. Put in the first quart of new oil. Pulled the dipstick to check the new oil level. Wouldn't come out until i REALLY tugged on it, THEN it came out - but the rubber stopper stayed with the engine block. I was able to force it back over the flat part, but now it's loose on the round part. I would say my dipstick is deformed as well - yes it's got a bend - more than one in fact, lol. But the point is - I don't know where I could/should epoxy it in place. I suppose I could assume that the 3.5 (3.5+ maybe 3.6) US quarts is the correct level - but does anyone have like a precise measurement I could get for correctly positioning on the dipstick? Or I guess I could just buy a new one for $30 on ebay - but this old thing needs just about one of everything - including many nuts bolts and fasteners - I'd just as soon fix/repair eveything I can....
Speaking of which: In removing the engine enclosure, I had to remove the hood(?). When I did that, I had my first access to the radiator. Figured I'd check the coolant. It looked pretty good, actually. But when I tried to re-install the cap, it wouldn't seat. Inspecting it, I noticed the collar was broken - nothing for the cap to seat against in a critical spot. Obviously somebody had broken it at some point in the past (and this from a supposedly "one owner" tractor that had been "babied" - yeah, right). My question: usually with cars, radiator damage like this is just not normally repairable. But is that true for these old Kubota's as well? I see "new" ones listed for sale from $165 to over $500. Comments? Suggestions?
