Oil pressure worrys?

[Ol 54']

I have always wondered if this here Wisconsin engine had any oil pressure? From what I have read some of these here 4 cyl. already come with a gauge, mine doesn't. So I plumbed one up to see what I had for pressure and theoretically I am showing around say 12 to 13 lbs. at about 1400 rpms. does that sound about right? Pops and I built this here buzz saw we'd called it to cut fire wood. Let me know what you think. Thanks..

It's getting on towards half of a century since I worked on these. As I recall, they used the same, or very similar packed media, coarse external thread oil filter that AC used right up into the 60's. What little oil pressure they had depended on the filter and the standpipe in the filter base. And that was far from a full flow system. It was only filtering a portion of the oil. So you may be getting all that you're going to get.

Yup. You don't want a lot. High pressure will heat the oil. Rule of the thumb is 10 lbs per 1000 RPM.

My Wisconsin is a model VF4D and does not have a place to install an oil filter? That doesn't make sense to me, I change the oil in every year though. The engine really runs good and cuts hardwood real well.

That's because the oil filter really has nothing to do with the oil pressure. Your V4 Wisconsin is not pressure lubricated.

The VF4 simply sprays oil from a series of jets to lubricate the rods and the governor, the balance of the engine is splash lube.

Some engines had a blank plate bolted low on the block, aft of the magneto. This is where the filter base was attached, if desired.

The VE thru the VP run 10-15 psi in the gallery.


I just noticed you have a distributor. The plate, if it has one, is behind the distributor. If you want an oil filter, you will have to toss the generator and find a distributor that fits the timing gear housing, (or go magneto) and charge the battery some other way. Some distributors had a pulley out the back to turn a alternator. Other times there was a stator under the flywheel.

The people who know about what you're asking have already answered. Looks like a nice setup, and I'm guessing you've cut a LOT of wood with it. Any reason you're just now wondering about oil pressure? Or just an excuse to tinker, something I can relate to. Can you post a pic of the whole machine? I'd like to see the saw if you have it hooked up.

And that's hot. May be a 20# difference on a cold engine in the winter starting and hot oil pressure in the summer at the 1000 RPM. If a diesel you want to run (C-compression rated) HD 15w-40, not 30 wt. if you expect to do any work. Helps protect rod and main bearings.

RedMF40 here are a couple more pictures of the saw.. ! Xzibit

 

[Fritz Maurer]

That thing will cut bigger pieces of wood than you can lift.

 

[RedMF40]

Nice setup but I can’t tell from the photo where you position the wood to cut.

The wood to be cut goes on the pivoting table where the tool bag is setting and the table is pushed forward into the spinning saw blade.

Ok, I see that now. Thanks.

Yeah that's basically it, Pop's basically drew up a set of sketches and drawings on a couple of plain old brown paper bags back in the late 60's. I did all the cutting and welding . Many a people have come by to make up there own drawings and pictures of the saw. Thank the good Lord nobody yet has got hurt on this here crazy machine, at full throttle you can cut a 12" piece of wood in about 2 to 3 seconds. My younger brother can really cut wood with it better than me. With out him knowing I was timing to cut 1 full cord of wood, it took him 21 minutes..

 

[RedMF40]

Hope you’re at least wearing eye protection. Your brother sounds like a study in efficiency. Twenty/one minutes, that’s fast.

 

[Ol 54']

Yes, eye and ear protection long sleeve shirts with boots, there are people that live a 1/2 mile a way and tell me they can here that thing.. This might be off the beaten path but the pictures I am sending you, are they sent 90 degrees rather than straight up, if they are I am sorry, I believe I have something wrong with the directional setting.. Have a good 1.

Back then we had more common since . Back then My Dad was Osha. We do something stupide and we didn't get fined, we got a butt chewing, that's why I have a 30 inch pants now.

Looks like somebody smarter than I, bailed me out on my picture frames.. Thanks

LOL, my IPhone is the smart one. It has an easy edit photos option for my library.
