Redneck way to fill rear shock oil

Postby twocams » Mon Feb 01, 2016 9:18 pm



My Wing is still on my cycle lift and Im still doing other things to her. So I decided to try and fill my rear shocks with fluid. Now this is not for those that are in a big hurry or faint of heart. Im filling one shock at a time so I filled a beaker with ATF for the right amount. So I put the air hose on the shock, using the 3 way valve connecting the other end to one of the ports to fill the shock. Plugged off the other port on the 3 way. I use a big syringe that I use for sucking out brake fluids and stuff. These work real well/lots better than turkey baster. You can get them at cattle/horse supply places. I put some fluid in the syringe pushing it into the air intake of the 3 way valve/nice tight fit. Then I needed to have the hose up kinda straight, but up in the air more than anything. So I hardwired it to my 6' ladder. Now this is all gravity feed and it does take a long time. But just fill syringe ( several times) and go watch a movie and have a beer. :lol:

if you are going to do that, take the plunger out, it would go faster, your making a vacuum like holding your finger over a straw

Good eye dean, yes you are correct. i did have to take the plunger out just after this picture. It had bubbles coming up at first and was draining goodish. But had to remove plunger after about 10 min. of playing with it.

Everyone says just take them off and turn upside down and let them drain overnight. Well I did both of mine all night and had about 2 drips come out. The relief valves inside or something weren't letting them drain. This is what I did: Got my plastic drain pan, short shop stool. Put the pan on shop floor held the shock up right ( hole at the top) then turn upside down over the pan. Only a little at a time comes out, maybe a tablespoon. I kept doing that up right then upside down. It may have taken 10 min. for each shock. You can shake the shock ( with good ears) and hear the fluid inside slash around as it gets empty. That should tell you when its about empty.I didnt worry about every last drop it may not all come out unless rebuilt. But 99% will come out that way.Well my 85 did anyway.

Just more information. My shop has only been 40 deg. And I find the ATF to flow real, real slow. So used my 1875 Watt hair dryer to warm up the shock and fluid some. I do have a heat gun but use the hair dryer for lots of things around the shop this time of year. :D Both shocks are full of 8.50 oz. of ATF now....book calls for 8.77 oz. but I dont think the shocks will ever know they were short changed.

Yup. Any time I am going to be changing oil during winter time, I always bring the oil inside for a day first, to make sure it's good and warm. No sense paying good money for thick oil that ends up sticking to the inside of the bottle!
