SOURCE: Evaporator cooler (Master Cool) one of

Hi and welcome to FixYa. I am Kelly.

First off... some thing has cause the vibration to damage the spider brackets to begin with. Could have been an imbalance of dirt build up on the squirrel cage blower, corrosion.. or a bad bearing.

There are few ways to fix this but all require the unit blower assembly to be removed and your still going to have to balance the fan before re-installing the blower.

Here is the parts list:
http://www.searspartsdirect.com/partsdirect/part-model/Adobeair-Parts/Evaporative-cooler-Parts/Model-MC63C/1568/0908000/P9070179/00001

Ths spider is not listed as a replaceable part.
You can have the brackets repaired at a weld shop however... welds have a tendancy to make the parent metal hard and if there is any hint of a vibration post repair the problem will only repeat.

I have never had much luck with a unit that got out of balance and caused support bracket failure.
They always result in call backs. The best remedy is to replace the blower. Good luck finding one as most parts for this unit have been discontinued. I am sure there are heating and airconditioning places that have a viable replacement blower that will most likely be a used one.

The blower wheel is roughly $93.00.

I am just passing on my 40 years experience dealing with swamp cooler issues. Having it welded may get you 2 or 3 more seasons at best but you must deal with the balance problem.

Thanks for choosing FixYa,
Kelly

How do you replace rear pads 2005 dyna glide


Hi Anonymous, it can be done with out removing the rear wheel or any brake lines, or any bleeding of brakes, all you need is a c-clamp and regular hand tools. First place a drain pan underneath the rear master cylinder, it's likely to overflow during the piston push back procedure, and remove the top and accordion rubber gasket and compress gasket back to it's flatest position then put it back on top of the master cylinder leaving the metal cover off. Next split the caliper halves by removing the 3 bolts and pay close attention to small o-ring so it doesn't get lost and location and orientation of the anti rattle clips. Leave the old brake pads in.Take your c-clamp and position it so that the screw part is dead center of the old pad and slowly tighten the clamp until the old pads have pushed the pistons back into the caliper half and the pad bottoms out. Repeat the process with the other caliper half. Install the new brake pads, replace o-ring and anti rattle clips and bolt the halves back toghther, torque bolts to 20 ft lbs. Check fluid level and replace top cover on master cylinder. Pump the brake by hand until you get a nice strong pedal and your good to go. Good luck

My double Cooler Master Cooling Fan R4-S4S-10AK-GP that i use underneath my laptop stopped working even though its not been in use for long time i bought it as part of a cooling pad with removable cooling...


If the fan spins and you find there is power going to it, then likely the electronic drive circuit has failed. You can get replacement fans at stores like Fry's and other sources.

Need help in replacing front and rear brakes on a 2003 mitsubishi montero full size


Hi there,

The pads are easy to change. You do not need any special tools. If there are no grooves in the rotors I would just put on new pads. Don't get cheap pads or they will squeek. I would strongly suggest that you flush out the old brake fluid. You will be amazed at how brown and gunky the old fluid is. Flushing the fluid regularly will help make your calipers and master cylinder last a long time. I like to use Valvoline Synpower brake fluid, it is a couple bucks more but it is DOT 4.

One last tip. When compressing the brake caliper piston you do not want to push the fluid back up to the system, because you might get some crud into the ABS module. Therefore, when compressing the piston, loosen the bleed screw to let the fluid flow out of the bleed screw.

This is how to get it done:
  • Remove the old fluid from the master cylinder resevior with a turkey baster. Top up master cylinder with fluid.
  • Remove the right rear wheel and bleed/flush the brakes with the old pads on. Top up master cylinder with fluid(important). Remove the caliper, open the bleed screw and compress the piston, close the bleed screw.
  • Install new pad and caliper
  • Bleed again. Top up master cylinder with fluid.
  • Repeat on remaining 4 wheels RR, LR, RF, LF.
Glad to be of help!!!

How to remove rear brake caliper to replace pads on 1995 Celica


With the wheel removed, look behind the caliper there are 2 bolts that hold the caliper in place. Completely remove the lower bolt and loosen the top. The caliper will then swing upwards exposing the old pads. Remove cover off master cylider reservior. Leave both old pads in place for now. slide the far side pad over to the near side pad and using a channel-lock wrench, squeeze slowly and steadily. this will cause your brake cylider to retract, pushing the fluid backwards through the line and into the reservior. Once the cylinder is retracted, remove old pads and place new pads on either side. Align caliper and swing it down. Replace lower bolt and tighten upper.

How do i change front brake pad on this car merecy sable 1989 -99


Remove the wheel, remove the 2 bolts holding on the caliper to the caliper carrier. You will need a large C-Clamp or a cailper piston tool. Place an old brake pad against the piston in the caliper and use the C-Clamp to push the brake pad against the piston to collapses the piston into the caliper. Also open the master cylinder cap and place a towel around the area to catch any brake fluid that would come out of the master cylinder as you collapes the piston, this is normal, but doesn't always happen, depending on the level of fluid in the master cylinder. Install the new pads and reinstall the caliper and wheel. Make sure you pump the brake pedal a few times before you take off, to get the pads against the rotor.
