Below are some pictures of my first look at the 40 HP Buffalo Olin. I bought this engine in Canandaigua, NY on 01/29/97.
The engine weights about 9,000 lbs., flwheels are 6' in diameter by 7" wide and weigh about 2,200 lbs. each, the bore is 12 1/2"
by 20" stroke.
The cylinder is mounted on the base and with the base sunken 6 inches into the ground...
You can see the ignitor in this picture on the valve chest...
And here are the huge flywheels....
You can get an idea from this picture how big the cylinder is. It is in the back of a full size ford pickup truck.
The work starts on restoration of the Olin...
Latch block and timing gear / governor mount...
Exhaust pipe flange, hot tube chimney, speed adjuster, & intake pipe. The intake pipe on the
right in this picture is 4" in diameter...
Timing gear / governor. The weights are called "pork chop" style. I think from this photo you can tell why....
Bearing caps....
The cylinder makes it into the shop. What a job that was....
An original Olin hot tube and burner. I think it is salvageable....
The valve chest is now removed and ready for disassembly...
This is the 2 stage intake valve...
This is the end guide for the exhaust valve and it is held on with 2 taper pins that had to be drilled out. I would hate to brake
that nice cast iron piece....
Getting the exhaust valve out took a little heat and the press. It came out real nice....
The intake valve, push rod and roller assembly are almost ready to go....
My oldest son wanted to help. I had him clean out behind the piston where we
would be pushing it out through....
The intake and exhaust ports are all sealed up and ready for pressure. The plate on
the intake port is 1 inch thick....
Here goes, The port-a-power is hooked up and ready to go. The cylinder has been
soaking with brake fluid and kero for quite a while and now it is ready for some pressure....
As you can see from these pictures we have now switched to a grease gun! The oil was
going by the piston and we couldn't get the pressure up. The next step was to use a grease gun....
After 3 hours of pumping (my son and I) we gained about 2 1/2 inches. The piston is 24" long
so we still had a long ways to go....
The piston has moved a total of about 16" and has started to come real easy. We used the track jacks
the rest of the way and as you can see the piston is finally out. We started at 7:30am and got the
piston out at 7:10pm....
The next day we removed the head to get the grease out. You can also see the grease
flow we had when the piston came out....
Here are a couple of pictures with the mess all cleaned up and also a look down the bore. It
doesn't look that bad but still needs a lot more cleaning....
The weather finally broke (the ground thawed out) so we went to dig out the flywheels and Base....
We then loaded the flywheels onto the trailer and the base onto my pick/up....
These next few pictures are of getting the wrist pin and connecting rod disassembled
from the Piston. I had the piston in the press and had to heat it slightly with the torch to pop the
wrist pin out. Notice it is a stepped pin....
The connecting rod and piston, finally a part. What a job....
I had a few helpers (my 2 sons) help out cleaning the water jacket....
The cylinder is now almost all together. There are a few more things on the cylinder to be accomplished....
Here I am getting ready to pour some babbit around the exhaust valve support. You can see in the
close up where the babbit will go....
Started cleaning the connecting rod in this picture. The end the wrist pin goes through
is solid brass....
The exhaust flange and 90 deg. elbow are all mounted and ready to go...
In these next few pictures I fired up the 5 HP Economy that run the line shaft and milled a slot
in a special bolt I had to make up for the valve chest....
The bolt goes in the bottom hole....
The Olin project is continued on
