Hey I really had a bit of a bad day on Thursday. Started good with picking up a 8V71 GM from a farmer down the road. The farmer unfortunately cooked one of his irrigation engines when we had our last rain, so we are patching up another spare engine to get him going again. ( it got up to 230 deg c when he came to check it- and it was still running but it totally cracked up the heads and destroyed a liner while doing so.)

I then concentrated on Pulling a wheel off a John Deere to replace the leaking wheel seal.

After doing as much as i could with that I attacked the GM. The blower had to be replaced and the oil cooler changed over to a smaller one. After i took the blower of the top the air box was completely chocka block full of greasy slime. The flutes around the cylinders were blocked and i started to scrap the sludge out. ( by the way, these engines are 2 stroke so they need the blower to push air into the cylinders. And what was happening with the air box full of sludge the engine was starving for air and had lost power.)

But scraping out the sludge was taking way too long so i decided to pressure clean it.

Haha! Well it was good until i hit a oil hole and it completely covered my whole body in high ash black diesel oil.

Yeeeah. Well it was good it was nock off time!!. What turned it into a bad day was it took me about 40 minutes to clean up in the shower:smile: The worst thing about the oil from these engines is the ash content- so it really stains your skin. So i scrubbed and scrubbed and scrubbed. I'm sure glad mum was in town when i came over for a shower:smile:

Hey thank you all guys for your comments.

BBW, I got my brother to take them for me. He loves to use my camera so it's a bit of a treat for him.


Streetshooter, I imagine you'd havta have a monstrously strong frame with some decent wheels. I think this would weigh about a ton with both heads on. But gee, would it sound good, a diesel v8 revving at 2200 rpm in a bike.

Thanks Bill, you've made me a proud man if you think my storytelling is good. I laugh at my own stories most of the time but i don't know if it makes sense to other people.


Sinophilia, I love working on big stuff and these engines are a good size. The cubic capacity of these engines are 14L or 14,000cc and range from 305 to 350 hp.
HA yeah, i assure you i wouldn't get my baby dirty in a hurry.
