I flipped the seal and drove it in with a 1/2” copper pipe scrap (straight cut and de-burred) and felt it “seat”. Going to monitor for leakage.

D_Mac 8,619 #20905 Posted February 27 So in the fall I was given a dynamark riding mower for free. Who can turn down free? It had on the back wheels these wheel weights . I removed them and they been sitting in my garage all winter. So I'm out in the garage today tinkering with my 875 plow tractor when it occurred to me.... put those weights on the front tires !!!!! So I did. Guess I will see if it makes a difference NEXT winter. Gives me time to paint them to match the rears. 9 1 Share this post Link to post Share on other sites

87 416-8 horse 420 #20907 Posted February 29 (edited) I just finished building a leaf blower for the front of my horse. It moves an insane amount of air! I built a custom frame out of scrap metal to hold it on. You can feel a breeze at 55 feet away. Edited February 29 by 87 416-8 horse 1 10 Share this post Link to post Share on other sites

I'll jump in and say that older warm air furnaces used belt drive blowers, you might want to contact some heating contractors for used parts. 1 1 Share this post Link to post Share on other sites

87 416-8 horse 420 #20913 Posted February 29 Welp, I got some bad news. I was testing the leaf blower and it blew up. I don’t think it could handle the rpm.💥 1 7 Share this post Link to post Share on other sites

Make sure you keep the rotor balanced, and I would put the large pulley back on and keep the tractor RPM around 1000. 3 1 Share this post Link to post Share on other sites

In my thinkering i be in first absolutely with Ed‘s. Without any modification firstly reducing dramatically the rpm‘s On the other hand after i looked little closer to the second pic, i see that everywhere where the finns be used as drive in the middle section they be definitely not harmed at all. Therefore i can imagine if the whole fan in the Middlesection becomes an complete outside mounted enstiffening Ring i. Eg. made from a 0,7mm thick 2cm wide little flat that goes outside the fan around the drum Fixed with a small welding spot or with a oneway rivet on two sites together to balance it, it may can improve the rpm‘s. because if the fins than in width be shorter they become more stiffness itself. Question is how much rpm they than can handle with that improvement and if it‘s a win or a fail at all. a gently and slow rev up will show how much rpm it can dealing with. 1 Share this post Link to post Share on other sites
Ed Kennell 38,178 #20918 Posted February 29 Just another thought, You can run the blower very slow and increase the air velocity by decreasing the discharge area. Something like this could be modified to create a wide high velocity sweeper. 4 1 Share this post Link to post Share on other sites

Hi Ed, I be not shure on this Dimension of Blowers what works better, reduce the charge or reducing the discharge Area of the Blower Therefore i have not enough own experiences to be 100% shure in that Dimensions. I just know, on my Shed Heater what work in combination with an Attached 1800cubicmeter Blower, that sucks the Hot air from my Heater and blow it thru a long Pipe to a Place where i need it. It runs fine up to 600 rpm - about 1/4 of max throttle. if i rev it too high, it sucks so strong, that the Pipe between heater and blower begin to collapse because of the suction. but i never try to reduce the outlet. I feared that the pressure increases much and do some other dubious unwanted things internally like whirls or something like that. maybe i‘m wrong in my thinking. Dunno. So i would go primary - as you mentioned earlier - with the bigger Pulley on the Blower for a transmission reducing for the RPM‘s on the Blower, So he can play with the Throttle and see what happens or when it‘s enough „Boost“ Pressure This equation can be calculated much simpler for needed speed. I think you mean a Nozzle at the end to increase speed, do you? 2 Share this post Link to post Share on other sites

The likelihood of being able to patch it up and have the fan be balanced well enough to use it is slim to none. Get another fan and keep the rpms reasonable. 9 Share this post Link to post Share on other sites

As others have said before me I would'nt bother trying to repair this unit. It failed for a reason. Chances are that the spot you repair will hold but then another section will give up. Looking at your exhaust nozzle I can imagine the pressure generated by the fan with the increased rpm's can't exit fast enough causing the fan to buckle under the increased stress. For a second attempt you could try to make the nozzle: - A, bigger or - B, transition smoother to the small diameter. This creates less pressure inside the blower but increases flow and speed at the tip of the exhaust nozzle, where you want it.

I think you mean a Nozzle at the end to increase speed, do you? Those fans are designed to move at a certain speed and move a certain amount of CFM. There is some leeway. But an old crusty fan is compromised. Using an electric motor, if you hop up the pulleys the motor overload will usually kick off before the fan will explode. Using a 14 HP gas engine will certainly overload the fan and cause it to explode. Restricting air in or out will have the same effect. If the fan outlet is restricted, the fan can't push the air out fast enough and the incoming air will increase static pressure to the breaking point. If the inlet is restricted, the suction created will pull the blades right out of the wheel. I saw this happen on a new air handler at a school during covid. The facilities staff decided to put highly restrictive air filters in to "Clean the Air" Blades came out and went through the evaporator coil. Of course they wanted it covered under warranty!
