I have a prochem legend se and a blower moter need to put 2 ae42 belts on. I can't figure out HOW? The pulleys are both on shafts and a tight area. They are facing opposite ways so the blower on bottom gets a belt on the back which goes on the front of the engine pulleys and the front pulley on blower goes to the back on engine. This is a kohler engine with a roots blower. This is a truckmount carpet cleaning machine but maybe just help with installing belts on pulleys

Hope this helps there's a repair video.....

If it were me, I'd probably just clean up the scratches on the pulley and or motor shaft. You can do so with a small file or sand paper. If you believe the friction caused by this roughens is due to the scratches, try smoothing them down. The grooves remaining won't harm the belt or pulley, but raised edges could. When I worked in an electric motor shop, we repaired many a motor shaft by filing the bad nicks caused by pliers and wrenches, with a little filing as the motor turned.

Hello. If the dryer is making a loud "banging" sound with clothes in it, the problem might very well be a worn out drum support roller. I need the complete model number to help you accurately. Most dryers have 4 drum support rollers--2 mounted on the back wall and 2 mounted on the front bulkhead. They generally are made of thick rubber with a machined steel core--polished so it glides smoothly on a matching machined shaft. The rubber can become worn and develop a flat area that "thumps" loudly. If the drum is empty, it may just "skip over" this damaged roller area. Now, if the dryer is squealing loudly, this is a good indicator of a bound-up idler pulley. It's a spring-tensioned pulley that the drum belt rides on to keep it tightly in contact with the drum to make it spin. Hair, lint, other debris often gets in-between the roller and shaft, causing it to bind up and wear on the belt--also causing a loud squealing sound. Next, a loud sound could be caused by an object getting caught in the blower housing and binding up the fan which pushes hot air. Socks, underwear, small pieces of clothing, etc. are NOTORIOUS for causing this! Check the blower for obstructions. I hope this helps you!

first put pulley onto blower fan housing i think you have to counter clock turn to put the pulley by hand. put you one hand inside the blower housing and hold the fan then use pliers and tight the pulley. now put belt on motor pulley first then put belt on blower's pulley it is hart to put on so little belt on pulley and use other hand and turn fan from inside so blower's pulley turn and belt get to pulley. last tight the pulley again. turn fan by hand to make sure belt run ok. hope it will help you.

Check the following:


1. DC motor assembly.
Make sure all the motor plate mounting screws are tight.


2. Idler pulley - DC motor assembly.
Make sure the idler pulley is not binding on the pulley shaft. Check the pulley for wear. Check the idler pulley shaft on the motor mounting plate for damage or contamination.


3. Drive pulley.
Check the drive pulley for wear, binds or damage to the pulley or pulley shaft. Make sure the pulley turns freely on the pulley shaft.


4. Motor drive belt - tray drive belt.
Check the DC motor drive belt for damage. Make sure the belt is tracking correctly on the drive pulley, idler pulley, and motor pulley. Check the tray drive belt for damage. Make sure the belt is tracking correctly on

Hi, there is a bolt above the idler pulley to adjust. First loosen slightly the center nut on the face of the idler pulley. Then tighten the adjusting bolt to proper tightness on the belt. Finally, retighten the center nut on the face of the idler pulley.

If you are talking about the pulley or blade clutch and pulley on the bottom of the lower engine crankshaft end, there is a bolt through the center of it that holds it to the engine. This bolt must be removed in order to get the pulley off. Sometimes they can be stuck with dirt and/or rust so you may need to spray the shaft with a good penetrating oil from the top of the pulley and let it soak for a while to get it free. If the belts are still on it, remove the blade belt and lock the brake/clutch down to remove the tension off the motion drive belt

14. Remove timing belt.
CAUTION:
1. Do not bend or twist the belt, otherwise its core
could be damaged. The belt should not be bent at
a radius less than 30 mm.
2. Do not allow oil or other chemical substances to
come in contact with the belt. They will shorten
the life.
3. Do not attempt to pry or stretch the belt with a
screw driver or any other tool during installation.
4. Store timing belt in a cool and dark place. Never
expose the belt direct sunlight or heat.

On one side of your machine you will find a cover that you can remove, the belt for the auger is in there. From what I can see there is no adjustment. Check to see how the belt looks.If it's chewed up it will need to be replaced.If you remove the belt try to turn the impeler to see if it turns freely, if it doesn't then check to see if there is something wedged. if nothing is wedged and the belt is off and it still don't turn by hand it could posibly be a bad bearing.if it does turn by hand. Also check the belt pulleies to see if they are ok, the only pulley that will sshould spin freely is the idler pulley, the one on the engine shaft should spin the moter so make sure you pull the spark plug wire off to check that one, and the auger pulley should spin with the auger.

Before attempting to remove blower, run the motor and note the direction of rotation. The blower wheel can be very difficult to remove. It is screwed on to the motor shaft opposite to the motor rotation such that every time the motor starts, the blower wheel gets tighter. The best way to remove, is to put an adjustable wrench on the blower wheel (from the motor side) and using another wrench or locking pliers on the side of the motor shaft where the belt goes. Rotate the motor shaft where the belt goes, in the opposite direction of normal rotation while holding the wrench on the blower wheel. It will be VERY TIGHT. If unsuccessful, the only alternative is to strike the blower wheel REALLY hard and break it off. GOOD LUCK!
