Yourpilotincommand Posted June 16, 2020 Report Posted June 16, 2020 I’d expect to see some fresh grease oozing around the grease fittings. I don’t think this was performed in last annual. No big deal, but I’d like to add some grease myself. What grease (Aeroshell 20?) and grease gun is recommended for a DIY guy. Please don’t shoot the newbie. I wasn’t successful finding an old thread where this is covered. Thanks guys. Quote
RLCarter Posted June 16, 2020 Report Posted June 16, 2020 The maintenance manual will show where and what grease to use. I generally wipe the zerk fitting along with what ever oozed out off (less mess) so it might be hard to tell if they do the same 1 Quote
RobertGary1 Posted June 16, 2020 Report Posted June 16, 2020 Get the mil number from your service manual. be vary careful. If you break a zerk it’s a pain to replace. I use a tip that had a release handle so you can remove it without putting stress on the zerk. -Robert 1 Quote

It actually is a big deal...gear needs to be re-greased every annual, else, you could run into what @RobertGary1 mentions above...or worse. Fresh grease needs to push out the year-old stuff, and I know mine has turned pretty dark after one year. I wouldn't want to leave it in there any longer. Not sure about the "E", but the Ovation requires Mobil MS28 grease (the red stuff). Aircraft Spruce stocks it regularly at a good price and ships regularly from the Dallas location. Steve 1 Quote
GeeBee Posted June 16, 2020 Report Posted June 16, 2020 I found out the other day that the 2 zerks on the front of the main (at the knee) will not accept grease unless weight is off the wheels. Maybe mine are really tight, but I thought they were bound up with dried grease. Checked the zerks, they were clear. So I put a zerk zapper on them and could not even push Marvel Mystery oil through them. Then I jacked up the aircraft, took the weight off the mains and grease went in and came out like butter. 2 Quote
Hank Posted June 16, 2020 Report Posted June 16, 2020 I've never had trouble greasing mine on the ground. First locate all zerks on one leg, clean them then add grease. I work from the top down. Mains each have 8 zerks; nose should have 11. Happy hunting! Oh, my C doesn't take anything exotic, I think I ise AeroShell 22? 1 Quote

Yep, that's par for the course. I generally only grease with weight off the wheels. For me the hard ones to grease are the small gear bell cranks in the belly. Those things take a lot of pressure to push grease through. Maybe partially because the system is under a lot of tension when the gear is down. Some things only grease well with the gear partially up. This is documented for the trunnion otherwise the grease will run out near the zerk and not make it around. You can't overlube the fittings so pump away. -Robert 1 Quote

Usually you only have 1 size so it will fit them all. It does two things... 1) You can pump much higher pressure grease because it doesn't pop off 2) You won't break fittings off because it releases with a press of the button; you don't wrestle it off. -Robert 2 Quote

Rob- that is one of the best additions to my toolbox. It will work on every grease fitting except one on the nose gear. (You'll see which one when you get to it. It's one of the main pivot points. ) 2 1 Quote

GeeBee Posted June 17, 2020 Report Posted June 17, 2020 I have the Lock N Lube coupler attached to the Milwaukee M-18 grease gun. Once you have an electric gun you will never go back. Attach the LockNLube, then squeeze the trigger with one hand. The more pressure the LnL coupler gets, the tighter it grips, after about 10,000 psi it will squirt grease out its side. https://www.amazon.com/Milwaukee-2646-20-2-Spd-Grease-Bare/dp/B00CMV6DT2/ref=sr_1_4?crid=2SNKRBVQJK6RA&dchild=1&keywords=milwaukee+m18+grease+gun&qid=1592352434&sprefix=Milwaukee+m18+grease%2Caps%2C182&sr=8-4 Quote
carusoam Posted June 17, 2020 Report Posted June 17, 2020 Ypic, +1 on finding all the Zerks... some like to hide... some like to escape... Some are only held in place by compression... On the landing gear... there isn’t an easy way to goof things up.... Greasing the prop... takes some additional detail... easy to mess up... even for some mechanics... Get a copy of the maintenance manual for your plane... There is a thread around here for all the various lubes that have been updated over the decades.... Just don’t guess... always ask... Best regards, -a- Quote
Guest Posted June 17, 2020 Report Posted June 17, 2020 I’ve found a number of grease fittings on the main gear swing arm that have seized bushing that will not take grease. I’ve had to disassemble the gear to then press the bushings out and then ream out the bushing hole. Clarence Quote
Greg Ellis Posted June 17, 2020 Report Posted June 17, 2020 Looking at the battery powered grease guns that are available, other than saving physical energy are they really needed? And by this question I mean, they say they pump out up to 10,000 psi. Some of the hand operated guns say up to 7000 psi? If I didn't want to spend hundreds of dollars on a battery operated grease gun (after buying the batteries it looks like they are close to $300) will 7000 psi be enough? I know that I may get tired doing it by hand but it is roughly $50-$70 for a hand operated 7000 psi gun compared to a couple of hundred dollars for the battery operated one. Quote
GeeBee Posted June 17, 2020 Report Posted June 17, 2020 When you are up under your gear on a creeper, and you attach your LockNLube coupler then pull a trigger.....you're going to say why did I not buy this sooner! My car has heated/cooled and massaging seats with bolsters that move with the turns. Do I need them? No. Do I like it? OH HECK YES! I never saw an armored car behind a hearse brother so you are not taking it with you. 2 Quote

Nothing following your hearse! You are like me. Get a tool system (I went Milwaukee M18) then just buy the bare tools. The DeWalt 20v by the way IS the most powerful electric grease gun around. Good choice. I also read a review of an Army guy who has dropped his DeWalt of the top of an M1A1 tank numerous times, never quits working. 1 Quote
