    So I can tell you how I fixed it, but pay you if I didn't. Hmmm.

    How do I take this thing apart? I have one that I bought for $10 and would like to fix it (it's DOA) but can't figure out how to get into it. It's also missing the bottom half of the screen. Can I get an exploded view of one anywhere? Thanks for any help.

First use hair dryer for a minute if you have.
second- bring any box with suitble size to mic and put a rice on it and put the mic on it for a couple of days{rice absorb wet and humidity}

Need to take it apart to replace the grill


Hi,

First you must loosin the connector.
There's a little shield with the serialnumber you can slide away.
Underneath that you will find the screw to loosin the connector/filter.
If you look inside you will find a bolt, unscrew that one and the element and grill will seperated from the housing.
Thats what I remember after 25 years.

Good luck,
Gerard

The belt that comes from the engine to mower deck keeps breaking. I've owned the mower for years and I have to buy atleast 12 belts per year. The problen is really bad now. A belt per cutting. I've...


I own a Craftsman rider, DTY 4000, 25 HP Kohler, 48" cut, 137 Hrs. It eats a belt about every mowing or two. Did all the stuff you did. Good luck from Sears. Had cousin who is owns a lawn & garden repair business look at it today. Says the prob. is this - The drive belt pulley (elec clutch) has too a narrow "V" and the angle of wear between it and the deck when the deck is in the lowered (mowing) position is too severe. If you notice with the deck in the fully raised position the pulleys line up perfectly. Then drop your deck and see how tightly bent the belt is downward and it makes sense as to why(my) belt would first roll over then break in a few minutes. The elec clutch pulley is sold as one unit PT No. 179334 $250.00, but I'm sure it would come with the same narrow V pulley. Waiting for word from my cousin. My last Sears Mower. Cannot even sell it in good faith.

How does one take a Sennheiser MD 421 apart?


Hi,

At the connctorside there's a small metal plate with a serial number.
You have to bench it a little, underneath there's a screw.
Unscrew it and you can take the connector out.
What I remember after 25 years is that there is a screw inside which is loosing the grill and element.


I've written it before with succes.

How to open a vintage sennheiser 421hl


Try contacting them here:http://www.sennheiser.com/sennheiser/home_en.nsf/root/service_contact-consumer Have a look at the bottom end of the microphone where the cable connects. What are the four holes for? I don't have one to look at but I do remember working on one about 20 years ago. Also I seem to remember that the side rails slid back. I hope this helps.

Heat won't switch back to cool 2003 turbo bettle


If you can get in there ,the little flap probably just fell down,like mine and my cousins. I cut a short piece of half-inch pipe to prop it back in place two years ago. He glued his three years ago . Both still work .I think I took the glove box out first then the panels on the sides of the front of the console to access.
