My 'mad toy' this year is a '99 JD 5210 2WD that's in pretty good shape o'all but runs a bit lumpy to my ear. It's my fourth 3 cyl (not counting the old crane's GMC 3-53) and doesn't seem to be running evenly on all 3. Not horrible or scary, just not as smooth as I'm used to. ![Confused :confused: :confused:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Meter hours (digital) are low if it's to be believed, but I won't be happy 'til I've checked the valve lash and injectors. All I'd need is the spec for the lash if there's nothing funny to getting the cover off & at 'em, but injectors would have to be pulled and tested before I'm satisfied that I've done all I could. (anything tricky to getting them out?)
Interestingly, new injectors seem to be half the cost of those for my cars (Buick 3800s in Chevies) and I wonder if I could have the OEMs tested for <$40 per, so just replacing them could be an option and a matter of being confident that new would be in spec OOB.
I'm no stranger to engine service, rebuilding, etc, and with a good service manual (OEM, I&T, etc) I'd tackle anything, but I'd like to check this stuff while shopping for one that doesn't cost more that a some 3PT attachments. Do I need much help or advice thus far, or is my usual over-caution making this look more complicated than it really is? (expect me to test compression before & after lashing if adjustment is needed ...)
Thanks in advance for all comments! tog
