Damaged block installing block heater L5240

[truckdiagnostics]

The only reason I recommended a sleeve over welding is that welding distorts and adds stress to metal. Repair sleeves have been reliably used for many years. I agree that the best would be to replace the block but for $3200! Is the tractor even worth that much?

I have used dry liners to repair cylinders several times and yes they have been used for many years. However, i have not used them to seal a water passage and I do not know how well it would last over time. He is asking a liner to seal out water with a press fit metal to metal seal. Now they may make a replacement liner that you can add some form of sealant in when you press it in, but once again not sure how long that would last. welding it and the liner would be an option if there is enough material there to get a good weld.

While you are there mount a turbo to that thing, you won't regret it!

Good luck fixing her up!

The L5240 already has a Turbo..

I think I can start poking around this Sunday afternoon. My camera arrived yesterday. I think I can shine a light through the frost plug hole and see it with the camera if it is below the piston skirt at TDC.

It's just a challenge, that's all. I've been face to face with a few of those before.

You kidding? That's a grand L!! I would give 4k for it...

Fair enough. I really have no idea what they are worth. Start to figure labor and "well I have it apart anyways I might as well do....". Sometimes it's just cheaper to eat your losses and buy something else.

Part of me saying "Is the tractor even worth that much?" is just to get people to think through the whole situation. I'm not saying it's a bad idea to fix that tractor up. I'm just saying think it through.

Hey Adiredneck, if you get a new block, will it have the freeze plug in it? Just thinking ahead.

I have used sleeves/liners to seal cracked cylinder walls on dry blocks several times. I have never had any problems. As far as durability, one is nearing 30 years old and is still doing the job.

All I have to say is..... bet you won't drill through a freeze plug again for a looooooooong time.

I don't know why anyone needs a block heater on a Kubota anyway unless you live in Alaska. None of my many had issue one starting here in Michigan in sub zero weather...ever.

I'm sure mine would start up just fine at any temperature I might even consider using a tractor at here in Wisconsin. Certainly down to -15, but... Using the block heater for 2-3 hours before I crank it just gives me a warm fuzzy feeling. It cranks easier, smokes less, and I'm sure the oil starts circulating faster. "Need" a block heater, maybe not. "Use" my block heater, oh yeah.

My old Ford smiles when I use the block heater for an hour or so before crankup!!! Just seems to be a lot easier on them.

Never had one. I preheat mine a bit (90 and 105) and crank 'em up. No smoke, a bit of rattling but all diesels rattle anyway. I don't have power in the equipment barn so no juice ... no block heater.
