Good Crank Info

[Dennis Cahoon]

Here's some good information I got from Rick Schell with the Honda "tin" crank he built for my 250 Honda Hotsaw engine.

Now....Here's a picture of the crank. Oh Yeah!

Nice EH!.....Do you have your gloves on?....Don't touch!

that is spectacular

There is nothing like quality to admire.
You do awsum work.

Lot of spit shine and elbow grease into that, looks fast.

Too bad its on the indide of the saw, maybe a poly carbinate viewing window is in order.

The information seems to point out some of the weaknesses of using synthetic racing oil in work saws.

Hi Mike,

Can you elaborate on what makes you feel this way?

Great Stuff Dennis!

Thanks!

 

[Mr.]

Good info Dennis. Those last few ponies are tough. Love those full cranks.

He make one in 880?

HAHAHA

Seriously how many horses to knock off .1 sec from the cut. From a ported 500. I bet it's real tough from where you are.

It's easy from where I am. HAHAHAHA

A full circle crank may not help a true chainsaw engine given the small crankcase volume that they inherently have.

I`m curious to hear what experiences anyone may have regarding full cranks in a saw vs the same model without the full circle crank.

Fuel/oil seperation and lack of rust inhibitor.

If nothing else they take up crankcase volume. I thought BWalker was alluding to converging pressures the other day. I encouraged him to speak up, but he didn't so just an ASSumption on my part.

He may be holding the ace on this one.

That info is a little outdated.
Most mix oils now are at least partially synthetic. The Husky XP oil i just picked up is a synthetic.
Ester based Synthetics oils can and do have corrosion issues. I have seen this first hand with redline oil and Klotz oil. High quality synthetics do not.

Dennis, I think I would mount that crank in a display case. Looks to sexy to put in a motor.

I was talking about something else, Fred.
What do you mean by converging pressures?

 

[bwalker]

I`m curious to hear what experiences anyone may have regarding full cranks in a saw vs the same model without the full circle crank.

My expiereance is that engines with small crankcase volume makes less usable power than those with bigger volumes.
This is why I believe that the 372 husky has a wider power curve than the Stihl 044/440. Of course I dont have the crankcase volume numbers for each and instead am relying on info related to me by a former Husky engineer that posted here.

Sorry about the misread. Love that crank.

I think I need to see a shrink; that crank made me a little flush just looking at it. Now I am feeling guilty. Great stuff Dennis.
