Hello,  Has anyone found a reasonably priced pump that will suction-out the gear oil for differentials ?    SHalver CLC #24920

Has anyone used the drill-operated pumps?  They seem cheap, albeit prone to breakage.  You'd have to mod it to fit smaller than water hose-sized tubing, but at $8-$20 may be worth a look.

Hello Scott,

I have owned a simple suction gun for decades, and it still works.  It functions similarly to the one in TJ's post.  It is a simple device.  Whether you use a suction gun, or a drill operated pump, you will probably never get a differential bone-dry without removing the carrier or cover (depending on type).  It is important to measure the amount of oil you remove from the differential so that you can replace a like amount and/or adjust the fluid level as needed.  I think this is better accomplished with a manually operated suction gun.

My gun is similar to the one pictured here: http://shop.advanceautoparts.com/p/performance-tools-suction-gun-w54220/9240026-p?iv_=__iv_p_1_a_214327102_g_12425515822_w_pla-61865531738_h_9007919_ii__d_c_v__n_g_x_pla_y_6201684_f_online_o_9240026-P_z_US_i_en_j_61865531738_s__vi__&utm_source=ACQ&utm_medium=cpc&utm_campaign=PLA&utm_content=shoppingcampaigns&gclid=CLWFtuDVlM4CFdgNgQodoCwMoQ

I have also used a hand operated suction pump for years.  Originally got it to empty the oil filter canister on my '59, but I've used it for all kinds of stuff.  Cheap, too.

I have one like Christopher and David mentioned, it may even be the Plews brand one and almost never use it for sucking.   Sometimes I will use it for filling but even that gets messier than it should be.   Maybe mine isn't an Plews one and that is why its leaky?  I remember using one in a friends shop that worked great so that is why I bought it.

For sucking the liquicav works well and for filling I get the pump top that screws into the top of the bottles with the hose attached.

Hello All, I think the drill operated pump may be the way to go for me (didn't know they existed).   Performance Tool has one but you have to be a wholesaler to buy directly from them.......... so I will find one of their drill operated pumps at a vendor.   Thank You for the comments..........   am off running in the right direction.    SHalver CLC #24920
