New to me 240D

[Menagerie-Manor]

Thanks! Just replaced the air filter, but will check the intake tube, etc. Exhaust is clean, no problem there and starts with no issues.

I did put 15W40 in it when I changed the oil. Man.. Hate to think that could cause the engine to bog when using the FEL. Sadly it's even just under it's own weight, it's not like I'm lifting anything or doing any work.

Appreciate the suggestion, I'll check the intake, etc. maybe it's clogged and just didn't realize it.

What RPM would you expect I could life the FEL without the engine bogging down?

My 2310 w/3 cy will lift the bucket without a struggle at around 1100/1200 rpm so I would not expect a struggle around 2K rpm on the 240D.

Did the hydraulics operate smoothly.

Thanks for confirming, I wouldn't have thought the RPMs needed to be that high.

The 3 point is really smooth (nothing on it though), the FEL is fairly smooth, but have to have the RPMs above 2k for it to not bog down. Another thing I noticed is if I curl the bucket and once it hits the stops if I keep trying, that also bogs the engine.

Mine will bog a bit on the stops too. Have you tried running any pto attachments to see how she handles the power output that way.

Ah, good to know.

I haven't run anything on the PTO, yet to aquire a PTO implement.

My YM240 won't bog lifting the loader (with nothing in it), clear down to ~800 rpm. That sounds like the hydraulic system is working harder than it should.

That was my suspicion. Need to research more on how to narrow down/troubleshoot the issue though.

Just checked again. Mine doesn't even idle at 800 RPMs if the gauge is correct, it will start cutting off at around 1k RPMs if I try to get it that low.

Also, noticed that when I do run it at 2kish RPMs and use the FEL, it drops about 300-500 RPMs. Is that normal? In general, the engine seems to surge quite a bit when using the FEL. @California, does yours do that as well?

I checked the air filter and pre-cleaner filter, both are clean.

Yeah, the 15W40 in the engine is too thick and will allow heat to build up.

Any of these should work or a brand that is like these.

Ok, phew... The multi-week saga has (atleast for this part) finally come to an end. This morning I was able to break out the rest of the bolt from it's resting place . Re-tapped the threads and now will start the process of cleaning the rest of the bolt holes and putting things back together. My partner is going to be happy to get this thing out of the garage lol. As you will see from the pics, I essentially had the FEL removed, just didn't separate at the hydraulic line. For anyone else, the key for me was getting the cold steel 1/4 chisel. With that, I was able to slowly break out the bolt.

Thank you again to everyone for the help/guidance/support!

Thank you for the update, glad you got it!

suparmansf I sent you a pm describing how my YM240 idles.

bmaverick - I've run Tractor Supply's "Traveller Premium" 15W40 oil (or any name brand at similar price) for near two decades and don't see anything wrong with it. 15W40 was recommended by the Yanmar Authorized Dealers (and gray importers) who posted here in the early days of this forum.

In the modern automotive world, and maybe with modern John Deeres, thinner oil is recommended for fuel economy and perhaps cleaner air, but I'm not convinced that relates to our 40 year old rigs. Straight 30 weight and a 5 minute warmup to get it circulating is what's in the owner's manual. I think 15W40 is a sufficient modern replacement. 10W-30 and Full Synthetic are likely also suitable but I'm not convinced they are essential.
