Precisely.  If someone wants a trailer queen, then none of that matters.  I just feel a lot better now that we are moving away from the diesel all together.

Do you have any idea if my diesel flywheel can be used with a gas engine?  Crankshafts are the same, rear plates are the same, clutches are the same, front pulleys are the same.  Starter, ring gear, and flywheel are different part numbers.  I'm guessing the gas flywheel is perhaps lighter?  But I can't think of any harm in bolting up the diesel flywheel--unless there would be some weird external balance issue or something.  I wouldn't think so, given that the cranks are the same.

I have a lead on a running D262 out of a D19 I'm pursuing and another out of a C2 combine.  The engine out of the D19 definitely sounds like the less complex of the two options.  But the seller is keeping his flywheel and starter.

Flywheels interchange.  RING GEAR TOOTH COUNT IS DIFFERENT I THINK.

I have a running gas engine coming for this tractor out of a D19.  I'll probably see it today.  We are hoping it doesn't need much in the way of repairs. Even if it does, I still think it's the best option in this case.  Question:  I'm assuming the "Mack" custom fire rings have no relevance to this engine.  The original AGCO fire rings were different part numbers between gas and diesel.  What are guys using for head gaskets in the gas versions?

I'm hoping there is no reason to pull the head anyway.  Mainly, I would like to return the "Mack" rings to their owner and need to know if there is any reason not to do so at this point.

Gas head gasket and fire rings were much thinner than the diesel parts. Gas engines had ZERO head gasket/sleeve sinking issues.

Is it even possible to weld the Sleeve holding collar in the block, around the Radii to reinforce this area? Or it could never be welded with enough precision or not warping it?

Might not be using the right terms here...but you get the idea. Make the weak point strong.

I have both a block and head I'm keeping for my Diesel. I have a different D262 in the tractor. Both head/block are original. I'm thinking I should have them inspected to know what I have.

My idea would be custom sleeves, either with wider flanges at the top (but there isn't an over-abundance of 'meat' up there to work with, if you know what I mean), or else make the sleeves to be a shrink / press fit at the top.  At the end of the day, you would be "dry sleeved" at the top and "wet sleeved" at the bottom.  With too much of a press fit, I worry about cracking the block between the counterbores, I don't know.  As the Dr. says, you still have the weak head to worry about.

At the end of the day, the diesel is cool, but we decided to go with the much more reliable gas version for this particular project.  I'm sure with enough $$$, determination, and a good machinist, anything is possible.

An extra .020" or .030" lip (.040" to .060" on the sleeve lip O.D.) would have to make an improvement. A press fit of any kind will wind up splitting the block right down the middle. Seen it before in my tractor pulling blocks. Mack always insisted the fire rings on the head gasket were too soft. They'd start to hammer out and in short order, the sleeve would start moving and then sink. I can't argue his logic, but the ledge/lip is still waaaay too inadequate, especially when you compare it to other A-C engines that never have issues. And then, there's the cylinder head.........

I am measuring .206" between upper counterbores 1-2-3 and 4-5-6.  An extra .020 lip on the sleeve reduces that to .166".  I would have to wonder about cracking between counterbores.  Maybe it wouldn't be an issue.  Isn't there someone on this forum somewhere that has done this (wider flanges) without issue?

My opinion:  This block is too small and too light to pack a 262 turbo diesel into, period.  They should have left it alone as a bored block, or reworked it into a smaller wet-sleeved engine that had decent sleeve lips.  I look at this engine and I see a gasoline / propane block, not a diesel block.

I get it that there was a horsepower race going on.  It seems that more than one poor idea / overpowered tractor got rushed to market at this point in history, did they not?  It was most certainly not just an Allis issue.

I'm happy to know that the D19 Gases were good tractors. I thought all of them had issues and not just the Diesels.

Head cracks aren't leaking. It looks as if the owner wants to roll the dice on a minimal repair. Will probably look into getting some "Mack" fire rings made and going with an OEM style gasket and lots of sealer and ARP studs.





My D19 diesel died yesterday. It overheated and is leaking coolant into the intake. My plan is to rebuild it over the next few years. You said above that you have a lead on a nos head gasket and fire rings. Did you ever get them, and if so now that your customer is going gas can I purchase them from you? Or can I get the contact information.

Thank you,
Tim

I am sorry about your tractor.  If you like it enough to rebuild it, are thorough, and do much of the work yourself, I am sure it can be restored to running condition.

The "OEM style" gasket I found appears to be a reproduction gasket that one of the Allis specialty vendors is obtaining from an unidentified source, possibly even having custom-manufactured for them.  They are currently experiencing major quality control issues.  I sent the gasket I bought back to them.  They have acknowledged the QC issues, refunded my money, and are trying to work with their vendor to obtain better gaskets. 

Olson Gasket (360-871-1207) has OEM style Victor gaskets in stock, with or without fire rings, your choice.  I haven't seen one of their gaskets, but I think they are essentially NOS AGCO gaskets.  This would be where I would go for an OEM style D262 head gasket, either with their fire rings or with custom-built fire rings from one of the companies catering to the high - performance crowd.

I have the wire diameter of the fire rings "Mack" used to supply written down somewhere . . . just can't lay eyes on it right now.  What alloy he was using, I have no idea.  They are nothing fancy--just a piece of wire brazed into a circle.

According to Pfouts, some of his customers are using a soft annealed copper gasket he supplies on their working D19 diesels with great success.  I guess I would want to talk to someone using a copper gasket in real life, it surely does sound interesting.

I do have a few other parts if you are interested, no pressure:

New Piston ring set
New Full gasket set
New ARP head stud set
USED pistons that look practically NEW (flat-top, no valve recess)
USED connecting rods
USED camshaft (may need cam gear), lifters, pushrods, rocker shaft
Recently REBUILT injection pump (low hours on rebuild) and (5) reconditioned injectors (never been installed).

PM me for more information if interested in any of it.  I will be returning the NEW parts to Pfouts in the near future if no one wants them soon.
