New OC3 owner in Virginia

[Lowspeedlife]

Hello all, my name is Scott and I live in Fredericksburg, VA.
I bought my first Oliver/Cletrac about a two weeks ago &
Got it home last weekend. I call her "Cleopatra" 'cause
she's so purdy! Hopefully she's not the last. I'm still looking
for a serial number, I'm sure I don't have to tell you guys
That the serial number plate is gone. The engine appears to
be stuck, the exhaust manifold is broken off, so I expected
the worst but the top end looks pretty good. A little rust on
one exhaust lifter, light surface rust on cyl #2. Cyl#1 had
some kind of insect infestation. All the bores look like they
will clean up ok. From what I read it may have a military
engine in her, the casting number on the right front is
1-4-57. The serial number on the block is 2499905TC
below that is stamped IXLB5. I've read That the fives
were not installed in these machines, if it is military, just
how hard are parts to get? I'd like to thank Blake and
everyone else as I am about to start asking a lot of
questions. Thanks everybody!

The IXLB is a long stroke version of the IXB engine.  It may or may not be military, it not a military spec engine.  An IXB5 is 3 1/4" bore 4" stroke. The  IXLB5 is 3 1/4" bore 4 1/4" stroke.  I don't have any info on that engine but I would expect most parts would be the same expect the crank and block.  It will have about 2 more HP at rated speed of 1750 rpm.   I think the 5 gear engine had a different governor setup.   A while back there was a NOS crank for sale on E bay.  It should make a good engine for your tractor even though it is not original

Thanks for the reply Robert. I had not been able to find any info on what the "L" in IXLB stood for. This is the first engine I have seen with a gear driven generator, the governor & the generator actually are driven from the same timing gear. The nose on the generator gear fits inside a recess in the governor gear. I am having trouble getting the distributor & water pump off of the engine. They are paired together driven off the same gear on the left side of the engine. The shaft that runs thru the distributor to drive the pump seems to be stuck,  because of this the whole assembly needs to turn or the timing gears need to move to allow it to be removed. I'll be working on that this weekend. Hopefully i can get the engine out this weekend, I'll feel better once I know the condition of the internals. Thanks again for the info.

Welcome to the forum Scott. We love pictures!

[Robert Barbour]

Scott I have never seen an IXLB but the setup you describe is very similar to what Hercules used on the larger engines.  So that engine would be a heavier duty engine than the regular IXB. I hope you find good things inside!

[Lowspeedlife]

Thanks Steve, I have really enjoyed your OC46 restoration. Just where in Virgina did you find your OC46, if it was near by I'm going to be really mad! LOL!
You should be able get a good look inside Robert, I have been taking lots of pictures. I'm still trying to get the loader off the front so I can get at the engine properly.

Scott, I found my OC-46 in Cle Elum, Washington. I live in North Bend, Washington (state)

Hi Scott. Maybe you mean my OC46. I found it up in the hills north-west of Lexington, VA - a place called Milboro.
Reckon I took 6 months off my trailer tires & brakes winding down out of those mountains dragging 8000lbs of crawler and spares  Chris

[Lowspeedlife]

Yes, I must have been confused about that, Lexington is a couple of hours away from here. I've hauled my share of stuff over those hills & been scared enough that I may have taken a couple of days off my life LOL.

WOW that worked too well! Let's try it again.
Cyl. Head SN :
Head casting numbers , this could be 696 or 969. looking at it here it is "G96".  
This one is across from spark plug #3 between the 4th & 5th head bolts on the left side:
Any one know what this one means? It's next to spark plug #4:
All I have found is that it is the acronym for the "Alaska Pacific Energy Corporation"  but I doubt it was made for them. Obviously it has no data plate on the engine, or tractor

Stamped on the crank between journals 3 & 4:
On the opposite side:
Between journals 1 & 2 :
And on the opposite side:
On the front of journal 1 is:

On the crank timing gear:
Below that is :
On the cam gear:
On the distributor/ waterpump idler:
Also on the idler:

I hope these are helpful to some one here so I'm not just taking up data storage space.
The crankshaft looks pretty good, I think the rod journals are o.k. But I'll have the mains re-ground, I can feel the light unevenness when I run a finger nail across it. I'll post pics of the bearing numbers later. The number one cylinder has had a sleeve installed at some point. It is the only one that is bad, I removed as much rust as I could before removing the piston but it still put some nice scratches on that piston. Will need to have the sleeve pressed out & another installed & may need a new piston. Rings on the others look good but ill replace them, obviously. Had a heck of a time getting number 2 & 3 exhaust valves out, broke the head off of 3 & I'm sure I bent #2. Cam looks good, bearings are tight but they will get replaced too. Guess I need to look at how much this is going to cost, surplus center has a 24 hp Perkins 3 cylinder for 2400.00 dollars that may be the way to go on this. Suggestions anyone?

Anyone know what SAE spec is for the bell housing on the little Hercules?  I will also be looking for sheet metal for her. Got a radiator (missing when I got her) from a guy named John Bohem in California, he deals in Siver king tractors, but had this Herc radiator that wasn't from a silverking. was a real nice rad before UPS beat the crap out of it, i think i can straighten it out. here's his web site. http://vintagetractors.com/parts.html  . From the looks of the radiator I don't think these had a pressurized cooling system, is that right? This engine has a water pump so that doesn't seem right. Could I replace the filler neck to a pressurized style & put a 4 psi cap on it ? I don't have an oil filter on this engine either, need to figure out how to fit one to her. Any suggestions or pictures of an original set up?
Told you I was going to ask a lot of questions!
