Or, getting into
my head.
The 830 started
pushing oil out of the left exhaust port sometime in August. It got to where it wasted a quart of oil
about every five hours. I have friends
who would have kept a quart of oil handy and let the dirt accumulate where the
oil seeped out between head and exhaust manifold and would have lived happily
ever after.
There are two
cardinal sins an engine can commit in my book.
The first is to be hard to start.
Nothing is more frustrating than a struggle to get an engine going when I’m
ready to go.
The second is to
use oil. So when the wheat was up
suitably and the tractoring season was over, I “tore down” the engine to do a “top”
overhaul. Everything in the middle of
the picture comes off. (Exclude the
radiator on the left and everything in the lower right corner behind the
exhaust pipe.)
The head weighs about
150 pounds, a bit much for an old guy.
Come-along to the rescue.
This all happened
early in October. The head went to
Burlington, the gaskets got ordered. I
was hoping to get everything back in time to work on it before the big
move. The mechanic shop rang my cell
phone as we neared Loveland with a load of “stuff”.
All things happen
for a reason. I needed a break from the
clutter of stacked cardboard boxes, from trying to find things in that cluttered
stack, from finding the best place to put “stuff”. About a week or so after receiving the call,
I trekked to Burlington and picked up the head and the gaskets.
The head overhaul
cost nearly $600. Here is what a
revamped head looks like. Note the shiny
new valves (the round things) and the nice green paint.
Here is what a
$250 gasket set from John Deere looks like:
(a cardboard separator hides the main gasket from the rest of the assortment. In the second picture the main gasket is
mounted on the block waiting to seal the head to the block.)
Speaking of
sticker shock, here is what a $123 oil pressure gauge from John Deere looks
like:
The head is now
buttoned up to the block. It is waiting
for an accurate torque wrench to bring it up to the required 275 foot pounds of
torque. I didn’t have a lot of faith in
the Rube Goldberg device which extended the wrench’s lever by 26 inches. I couldn’t do the math to figure out how much
torque I had to show on the torque wrench when its reach was extended by 2 feet. Plus, it was a chore to keep the torque
wrench from turning on the socket handle and at the same time getting an
accurate reading on it.
There is quite a
bit of work left to be done, but the covers are on and the openings closed well
enough to keep out the vermin and the weather. Besides, I will need another
break from the clutter of modern existence.
I will escape into the simplicity of the past where 270 foot pounds of
torque are on the tractor’s head bolts, not my molars.
Here is a World
War Two joke. A Native American joined
the Navy. During his enlistment he was
trained as an electrician.
Unfortunately, he also contracted a chronic case of dysentery. When he mustered out, he returned to his home
on the reservation. He brought with him
both his electrician skills and his health problems. Now his home was a bit behind the times as
far as modern conveniences, so he set out to help bring light through
electricity to his people. One dark
moonless night, his chronic health problem surfaced and he raced for the
outhouse. Because the outhouse was
unlit, he failed to find it in time and the result was an unfortunate
accident. Resolved never to be
embarrassed by that sort of thing again, the young man set about the very next
day installing a light fixture in the outhouse and connecting to the
recently-completed power supply. He
flipped the switch and on came the light.
The completion of
the project entitled him to a place in the record book as the first Indian to
wire a head for a reservation. (Thanks
to that great jokester, Uncle Pete)
This was one of the most interesting articles you've written on your blog. The old saying "Faint heart never won fair lass" might have a corollary that goes something like "Faint heart wont make old tractors last," but anyone with a lack of courage wouldn't be happy undertaking that task. I expect the tractor will have better power and lower fuel consumption now, in addition to no longer using oil.
ReplyDeleteIn looking at your torque wrench assembly, I think that's one of those things like ones that I often encounter in my carpentry attempts - even if your math is immaculate, there's too many unknowns like friction, misalignment, "play," etc. that would make it doubtful that you could be confident you'd gotten the correct torque. Here in Broomfield, you could go to a rental place and rent a torque wrench with enough capacity for the job. I'm wondering if the Napa place in Limon might have one they'd loan you.
