    I would like partially take this lens apart enough to get some graphite base grease on the slide and the other parts that need it but I have no idea how to get it apart can you give me any clues its a Sigma 170x500 for a AF Canon
    I will not use WD40 as it likes to gum up to bad.
    Thanks

The rubber grip that surrounds the barrel comes off which is very hard to remove without stretching it out of shape. Once off the screws can be removed to add a few drops of solvent to loosen the stiffness

We used to warm the assembly slightly, and then use graphite grease very carefully, on the slide...work it in & out, a few times... a good quality penetrating oil can also carefully, applied too, & can free up and make it run smoother. Just be gentle. but firm.

Hello. Get an aerosol can of a penetrating lubricant called WD-40, with a tiny spray tube attached. Use it sparingly and apply a wee amount around the part that you can reach. Reapply as needed. Joe

Where can I find out how to take apart a Sigma 150-600mm contemporary lens?


Taking it apart is not the problem - re-assembling it will be. Unless you have access to an optical laboratory, where laser instruments can measure the exact tolerances required, don't even think about it. You will be left with a pile of optical components, and a far higher repair bill than if you had just let the experts sort out the problem in the first place.

On my new 16x52 monocular the main focus is stiff. What can I do?


you want it dampened but not too stiff. If it gets loose, it will defocus when your eyes hit the cups. I imagine you could try and work out the bind but in reality it should be stiff to focus. Focus helix uses a heavy white lithium grease. Dont dilute with WD40 or any other household lubes.

Freezer fan makes sounds like rubbing back wall


Two things come to mind - either the fan has accumulated enough dust and debris to make noise or, more likely the fan's bushings are worn out and/or the original lubricant has dried out. The fans usually have sealed bushings and once you take the freezer apart far enough to get to the fan to service it, it is much easier and cost effective to replace the fan. If you take the fan itself apart and re-lube the worn bushings your "fix" very likely won't last very long.

Hello, I have a Yamaha R-15 Version 2.0 2011


It sounds like the service you got forgot to lube the cable or the rod to the brake also there should be a service cap screw on the freont fork to lube it also and check your front axle bolt to be sure it is at the proper tourque. If either is to tight or loose it could be dangeraus. As far as the water is concerned the bike shouldn't have a problem there. Good luck and be carful.

You possibly have corrosion or contamination built up in the lever pivot point. Disconnect the cable and try lever - if it is stiff or difficult to move, you'll need to take the handle off, clean pivot and contact points with a SOFT wire brush ( brass brush recommended) lube it with white lithium grease and re-install. check for freedom of movement before re-installing cable. If it moves ok but cable is stiff, you'll want to next lube the cable with a liquid spray lube - sometimes the new cables are not properly lubed!!

A big problem with these heaters ans well as others is the motor driving the fan. The bearings get stiff from dirt and do not spin fast enough activating the over temp device of the heating element. Check the motor out by placing the unit in fan mode them pull the plug or turn off looking at the fan to see how many revolutions is makes with no power applied. It should rotate like five times or more indicating freeness. If it hals to a stop immediately after power is removed the motor bearings are tight.
If your handy you take apart and oil the shafts using 3inone motor lube. Clean the motor of dust and dirt drop a few drops on the shafts near the bearings then work it in by hand rotating the blades. Do this a few times reassemble then ler ripp!!!

If it doesn't turn correctly, that strongly indicates you didn't reassemble the lens properly. Take it apart and try again. And I hope you have a lens collimator and other tools to ensure you get the lens elements aligned properly.
