Attention: Welcome to our new aircraft hydraulics section! We hope you find this section we have put together informative and interesting. You may notice that some part numbers and so forth are blurred out. One reason we didn’t want to post full part numbers because it has taken us months of searches to get the information we have. It wouldn’t be fair to us to just give up our hard work and research. Not too many people know about this stuff and the ones that do don’t want to talk about it. We feel this is just the right amount of info so we don’t upset anyone on either side. The biggest reason for not giving out full part numbers is because we don’t need every lowrider to call up aircraft surplus places looking for things. Most warehouses don’t want to sell to lowriders and the ones that do are raising their prices beyond a reasonable amount because people are willing to pay to much for stuff the warehouse considers junk. Lets keep prices down and think about it before you offer a insane amount for a used pump that needs a rebuild. If you are going to track parts down don’t say that it is for a lowrider. Know what the full part number is, what aircraft it goes in, the proper name for the part and the function of that part. Take the time to research the surplus industry and know the lingo they use. Remember not to use lowrider lingo when talking with them because odds are they have a different term for the part you are looking for. With a little research and some luck you’ll be able to find what you need.
The 280 is a very reliable pump for lowriders. In lowrider circles it is sometimes called a “Screaming Mimi”. It is bigger than the popular 777 unit. The motor on a 280 unit is around 3 HP and the pump output pressure is around 1400 PSI. The Pesco 280 is a good pump for a two pump system. Not too long ago we were lucky enough after hours of searching through part numbers to track down four brand new units that have been in storage since 1944. They were in good shape but being in storage that long had aged the pumps so they were cleaned up. We’ve seen some of these units on Ebay but be careful as they may not be tested. We highly recommend getting your pumps from ROLLINAROUND’S Hydraulic Supply, all pumps are checked over and motors are tested..
Pesco 280 Power Pack: Useful Information
We will have more in this section soon. We will cover setting the relief on the pumps and a overhaul in the near future on a used unit. Also we hope to have some more parts diagrams in the near future to share with you.
New Pesco 280 Power Pack: Clean Up
This section covers the clean up of four brand new units we got from surplus storage. We didn’t take the pumps apart except to check the motor bushes because we didn’t want to take apart and possibly mess up a good working unit. Soon we will show a overhaul of a used unit.

Warning: Do Not Take Your Pesco Pump Apart As It May Cause A Problem In The Pump!
This section is for educational purposes to explain the inner workings of these pumps.
Below we are going to take a Pesco pump apart for inspection. Pesco pumps are a gear pump so they are fairly simple in how they operate. You’ll need a few simple tools to take the pump apart. You will need wire cutters, needle nose pliers and a 7/16 open end wrench.
