Just curious...what advantage does a water cooled small engine have over an air cooled engine?  I sorta like Kawasaki...beginning with a Mach 3 and the Kawasaki plant right up the road in Maryville, Missouri.

Larry...

Some people believe the engine runs cooler and lasts longer.  I think it is superior in hotter climates, which I'll prolly be doing a lot of work in.

Drawbacks can be, you have a cooing system to maintian.  Your engine could overheat if it fails.  Radiator has to be blown out and kept free of sawdust.

Air cooling fins can become clogged on air cooled engines though also.


I like Kawasaki a lot.  Mabey cause it contains the word Saki..  :o..................... :D

The reason I was asking was so you could calculate how much more the kawasaki weighs as that additional weight will be felt when "lifting" the engine and that radiator and its coolant everytime you have to engage the clutch since you dont have an auto clutch.

I don't know if it will be that much different Jeff, but we'll see.

So what's the fix, the auto clutch?

The liquid cooled will be smoother, QUIETER, and with reasonable maintenance, last a lot longer.

Jeff...

It looks like it's about 25lbs heavier than a Kohler 25hp, not counting the antifreez.

You might want to ask some of the sawyers that have been engaging that manual clutch for years on the opinion on the auto clutch. I brought it up because of some comments by Tom and Customsawyer this weekend during some of our conversations. I have to think that all that extra weight and where or where it may not be located is going to have repercussions on you as the operator, and possibly the design and function of the machine.

THAT's the last time I wash mine by hand!..  >:( >:( >:(


Jeff,

You got me wonderin' so I did some closer checking.

The Kawasaki is only 15lbs more than the new Kohler 28, plus the weight of coolant (oil's the same).

The new LT40 HD with the Kohler 28 has no auto clutch option per the Wood-Mizer website.

I would tend to believe as easy as the Onan 24 engages, 20 or so more pounds is not going to make much of a difference, but I can always add auto clutch on later can't I?

About what did it cost you?... smiley_beertoast

I dont have an auto clutch, Ive just talked with people that have spent a good deal of time without one. It will certainly be interesting how yours works out. I do know the "clutch" works on using a lever to lift the engine to tighten the belt and at the same time release the brake. As you increase the weight of the engine, you increase the amount of force it takes to pull down on that lever. Depending on where that added weight is located on the engine might also add to that additional force required. For example if you have to move the engine from its standard mounting location to a new one.

Hey JP, get that thing going so we can get some realtime feedback. I am considering the same engine for my LT.  Maybe if the engagement is a problem you can add a gas cylinder to the lever or the mounting plate to assist you. They are using those things in all kinds of applications of late. LW

I should be taking the Onan off to day LW, and I've got to grind off the old alternator.  I'll post a pic so you ca see what I mean...  :D

Prolly at least set the Kawa on her an start lining things up to see where I'm at.  I don't think the weight will be a problem, but I was wrong once (1) before..  :D

Work progress for today...

Got the Onan off, and had to grind some of the gobs of weld off the alternator mounting bracket just to get the DanG unit off..  :D









That is actually an Allen wrench gobbed in the right hand corner of the mount..  ::)........... :D





Here she sits with muffler and air cleaner, and a new Delco alt.  Also I have the new debarker just sitting in place so I can decifer what's gonna work where.

I was thinking of mounting the alt on the oposit side because of the weight like on the new Lt40's, but it would be in the way of the oil filter, the debarker, to close to the muffler.  If I turned it 360 then I wouldn't be able to get the belt cover on.  It could be placed in there with a lot of work, but I started placing it back on the other side like the original.






It fits there nicely.  There's plenty of room for this engine..  :) 8) :)








Now the weight problem. 

I understand that has been a real problem for WM owners, and I compared the weight of engaging the clutch with the Onan on, and then this heavier engine, with the heavier alt.  It's definitely harder to engage, so I came up with a fix.

I call it the "JP Clutch"..  :D

Looks like ya got it figured out. If that hood spring works during operation, I have a feeling you could sell those springs at a healthy profit. Heck, ya might even make the front of the woodmizer news for that mod :D

I hope y'all weren't thinking I was dissing anything here. I have been worried about how I might be able to run my mill this spring and the recent personal conversations I have had been privy to about the issue had me wondering if it had been considered. Actually its similar to what I did this last past fall with a bungee strap as an assist. The clutch mechanics is so simple that there has to be a multitude of things we can do to assist it to avoid any repetitive stress. Believe me, I don't think I can handle any.

That raises a question in my ever active central processing unit. Does this spring lower the overall tension on the belt? Or does it increase the pressure? Or...does it change it at all? Good work JP.

P.S. I like the setup on the pallet behind the tractor. LW
