Since both clutch packs seem to be pulling well, it would be the steering brakes that hamper turning with a load.

If his steers like mine, it's more of a traction issue. I was pushing some briar bushes and when I got a big pile it didn't want to steer very well. The one side would stop and the other side would just spin the track.
I found that if you do it long and gradually it would work, but you couldn't do any quick turns.
I need to adjust mine some because the amount of pull is different on each one.
Is it normal to have to pull the seat to adjust them? I can't see down in the top cover or get anything in there to get the brake band adjusting nut to move.

Be careful turning under load, even avoid it. All the torque of the push is being split between 2 finals. When you pull that steering clutch the torque goes to the other side. = broken finals = $$

My seat is not factory but i have to remove the bottom cushion to see something in there. The brake band nut is not easy to access without doing that.

You're right there. Good point. Also, as the torque is applied on one side, you increase the risks of stripping the differentiel hub inner splines. it wears faster... Parts that are not easy to find can be damaged. When pushing heavy loads, personnally, it is with both clutches engaged.

Well, it's been a long time i wrote on the board but that's a good thing. Lest posting more dozing!!!

I got this compression from the engine into the rad. It turned out that the head was cracked:

Then field repair again...

After 2 years of repair i said to the dozer: you'll do some work or finish as the most expensive flower pot around. I did 20h with it so far without a problem. Actually i'm surprise how much pushing it can do. People who tought i was crazy fixing this actually would like to have one...

We took around 15 videos of it working so here is are two of them:

http://s1235.photobucket.com/user/440ir ... b.mp4.html

I did A LOT of what i had to do on my land. Still couple projects for shure. I still have to rebuild bull 1 which is more in shape that this one... Motivation is there. I hope i'll have time to complete it this winter.

Your machine looks and sounds good. I've been using my 420 lately to push around some boulder - filled free fill (Vermont topsoil?). Working in small bites, the machine leveled and graded over 500 yds. without a hitch. Sure beat using a shovel. Very satisfying when a repaired machine works as designed. Best wishes. Paul

Thanks Paul. Yes it is very satisfying to work with it after all the adventures! It is surprising how low the gas consumption is vs work accomplished with this engine. I put a 5 gallons in the morning and i don't worry about it for the rest of the day. The undercarriage needs serious work but i keep that for next year.

I wish you many hours of fun on your 420!

Well i sent the damaged motor head to an engine shop and here is the pic:

Image

The mechanic there told me it has seen better days but that they can fix it. #2 cylinder area has been repaired in the past as we can see. The cost would be 350$ peened, surface machined and assembled with valves and everything. A new head goes around 550$... I think i'll go with the repair and I hope it holds. If not i'll pay twice :cry: .

Ouch, that doesn't look good iron popper.

Seems like the new head would be a better route to me.

Is this a common failure point on these?

Yes, I have had several heads fixed. Not sure that it is a weak point in the head, or a weak point in the head of the operator that let it overheat at some time in it's life. Fixing is no problem if you can find someone that will do it, and do it reasonably. If not, then new head is the best option.

:lol: :lol: :lol:

That's what i think too. Overheat might be the cause. I already changed the gauge, rad and thermostat on this one. I think I'll have the head repaired and will put a new water pump on the engine for the difference of what a new head would cost. I suspect the coolant flow to be low a bit. I never went over 180 F in operation even in very hot days but when i stop it the gauge will rise up to 210 F... I tought it was because the exhaust is very close to the probe. The engine never lacked power exept that it quit starting when this happened.

I have a question. What should be the manifold temperature on this engine? It runs pretty hot. I used a gun that measures up to 600 F. I know it goes above that but i don't know the maximum... Then i could have a carb problem, poor mixture or something.

Thanks,

Don't know for sure, but working in the dark under a pretty good load, I have had the muffler glow a dull red. If your timing is off, they will really glow, but by that time, you are probably looking at valve damage and more.

That's good then. I never reached red color yet! I set the timing using 'manual' method then I used a timing light to verify it. It was good.

I have another question :roll: ... With the replacement head i borowed from bull 1... When i give throttle, the acceleration goes smoothly. If I go quickly to idle position, the motor will back fire bad. But if I remove throttle a little bit at the time, i can control the backfiring issue.

What could cause this? Advance mecanism sticking? I didn't have time to troubleshoot it at the end of the season.

Thanks again.

I recall plowing heavy, wet snow with the 420 and watching the snowflakes disappear into little steam puffs just a fraction of an inch short of the glowing red muffler. 8)
