Meyer T-5 T-6

The First Electrolift units were the T-5 and T-6


Meyer U-13

Followed by the U-13 featuring Power Angle

Meyer E-45 Electro-Lift

Then came the E-45, with Power Angle


Meyer E-46 Electro-Lift

The E-46 likely came out after or at the same time as the E-47

Meyer E-47 Electro-Lift

The E-47 Electro-Lift is likely the most common
unit that is still in use today.


Meyer E-60H Quik Lift

The E-60 came next.

Meyer E-57 Electro-Lift

Followed by the E-57 (yes the numbering went backwards)

Meyer E-60 Quik Lift

The E-60 was updated with a new motor and PA Block.

ALL of the above units have been discontinued.

 T-5 T-6 -The T-5/6 was a plunger type pump. It had a Delco-Remy starter motor to operate the pump. The pump raised the plow blade. To lower the blade, there was a cable connected to an arm on the unit, that let the fluid out from under the lift ram, back into the reservoir.

U-13 -   The U-13 was a gear pump. It had a Prestolite motor that turned the gear pump. It had a spool valve block attached to the side of the base, which was operated by two cables to control lift, and power angle.

E-45 - The E-45 used the same design as the U-13, except it had a valve block with solenoid valves.

E-47 - The E-47 used the same gear pump and Prestolite motor as the U-13 and E-45. It used the same lift ram and fluid reservoir, and top cap too. The design of the base was changed to accept the new PA Block. The E-47 is probably the most popular snow plow pump ever made. They were offered in an E-47H model too. The H stands for High Lift. It has a 2" longer stroke over a standard model. There are thousands of them in use to this day. Every part of the E-47 is still available from Meyer Products. Aftermarket suppliers offer many parts for the E-47 as well. The E-47 patent was granted November 20, 1973. It was officially discontinued around 2005 as far as being part of a complete new plow system ordered from Meyer. It was replaced by the E-57 on new systems.

E-46 - The E-46 is an E-47 unit with a block off plate installed instead of a PA Block. It does not have power angle. It can be converted to an E-47 by removing the block off plate and installing a PA Block, the same as an E-47 can be converted into an E-46 by removing the PA Block and installing the block off plate. Also available as an E-46H.

E-60 - This was a totally new design. It was the fastest unit Meyer had made to date. The pump itself had a higher GPM flow than previous units, and the standard E-60 pump put out 2500PSI. It was set at 2500 PSI due to the small diameter of the lift piston on the end of the lift ram. The small surface area required 2500 PSI to lift the larger blades. The pump itself is capable of over 5000 PSI but the top cap of the unit will blow into pieces at approximately 3000 PSI. This is why it is VERY important to have the pump pressure set properly, with a pressure gauge. Also available as an E-60H model. The H stands for High Lift, it has a 2" longer stroke versus a standard model E-60. The E-60H utilized the same larger diameter lift piston as the E-47, so pressure was only set at 2000 PSI, which was capable of lifting the larger blades. It also meant less amp draw on the vehicle electrical system with the lower pressure setting. It also featured an adjustable drop speed for the first time. It was discontinued by Meyer Products a couple of years ago.

E-57 - Meyer went backwards with their numbering. The E-57 was an updated version of the E-47 in that it had a new larger pump, and the same larger motor that the E-60 used. It also featured a newly designed PA Block with one of the fittings coming out the side of the PA Block. It had a 2 lug Iskra motor on it. One lug for power supply, and one lug for grounding the motor. This was an improvement over the single lug Fenner motor used on the E-60 units. The single lug motor used the motor mounting screws and the base of the motor making contact with the sump base for a ground path. Corrosion was (and is) extremely common, and the unit will start acting up. Poor grounds create all sorts of gremlins. The standard E-58H unit Meyer uses today is an E-57 with an updated PA Block that allows the drop speed of the plow to be adjusted. Like the E-47 and E-60 before it, the E-57 was available as an E-57H model as well. EZ Plus mountings used the E-57H as standard until the E-58H came out. The E-57 was discontinued by Meyer Products a couple of years ago.

E-60 New Fittings - The E-60 now used the same PA Block and 2 lug Iskra motor as the E-57. Nothing else changed initially. The standard E-60 began using the larger diameter lift piston, and pressure was reduced to 2000 PSI. No other internal changes.

The E-58H replaced all of these units in 2008/2009. There is no standard E-58. They are all H models.

More current models:

Meyer E-58H E-68, E-68, E-78, E-88
Meyer V-68 Meyer Aggressor E-70
Meyer E-72 Meyer V-71
Meyer V-70 Meyer E-73 SOS

E-58H - The Meyer E-58H became the standard hydraulic unit around 2007 for all Meyer straight plows bought as a complete plow system. It was also made to be backwards compatible so it was also the replacement for the E-47, E-57, and E-60 units. It required drilling a new hole in the Lift Arm on EZ Classic and EZ Custom / Custom Classic mounts. This was because it is only available as an H Model, which has an 8" stroke, and on the older mounts the back of the tank will hit the Lift Frame at full lift, and damage the tank. Additionally, on some older mounts the Motor will also hit the Lift Frame, and the original PA Block used on the E-58H (with steel Coils), the Crossover on the bottom of the PA Block will also hit the Lift Frame, and in some cases bend and crack the Crossover. Original E-58H units were painted yellow, and later units were painted black, and the PA Blocks left bare aluminum. Brand new they always came with the hard plastic cover. The PA Block was replaced with a new (Bucher designed) style that uses the same Coils and Valves as the E-72. This PA Block change was announced in November 2012. It uses black plastic Coils as opposed to the original that had steel Coils. The control wiring is the same as the E-47, 57 and 60. Default is still left.

E-58H, E-78, E-68, E-88 - Well these all came about at the same time. There were good intentions, but in the end, the E-58H and the E-68 are the only ones that survived. The E-78 and E-88 were wireless control units. There was a "brain" mounted under the pump cover right on the pump along with the Motor Solenoid. The controller was the truck side transmitter. There were no control wires from the truck to the plow, only a power and ground directly from the vehicle battery. The E-78 was a wireless unit designed to work with EZ Plus mount plows, and the E-88 was a wireless unit designed to work with the Xpress Plow only. The E-78 became the E-58H with wired controls, and the E-88 became the E-68 with wired controls. The units themselves were identical mechanically to their wireless counterparts. ALL of these units were H Models (meaning they have an 8" stroke), and there was never a standard (6" stroke) version of them.

V-68 - The Meyer V-68 was an Italian made hydraulic unit. It was made up of 77 parts, and was short lived in that it was only used for a couple of years before it was replaced by the V-70.

E-70 - The E-70 is a hydraulic unit designed for large trucks that run the Road Pro plows. Most trucks in this class have central hydraulics, but for those that do not, there is the E-70. Like ALL Meyer hydraulic units, it is available as a 24 volt unit as well.

E-72 - The E-72 replaced the E-58H as the standard straight plow hydraulic unit in 2014. Prior to 2014 it was offered as a premium hydraulic upgrade (beginning in 2010). At the time ,the E-58H had a 3 year warranty, but the E-72 had a 5 year warranty. As of 2014 all Meyer hydraulic units bought as part of a complete plow system came with a 5 year warranty if registered with Meyer online. The E-72 is another Bucher built unit for Meyer. Like the V-70, it too has a plastic fluid tank, and all the benefits that come with it. It is very similar in design to the Monarch hydraulic units used on electric over hydraulic small dump bodies that are very popular and on thousands of mason dump trucks. It is just a vertical design instead of horizontal. The unit only has 23 parts, compared to say an E-60 which has 92 parts! The control wiring is the same as the E-47, 57, 58H, and 60. Default is still left (no valve to angle left).

V-70 - The Meyer V-70 only has 26 parts, compared to the V-68 it replaced, which was made up of 77 parts! It is a Bucher (formerly Monarch) unit, made for Meyer Products. Original units had a steel tank that was quickly replaced by a white plastic tank. The plastic tank allows you to see the fluid level, and does not rust like the steel tank. a stainless aviation (hose) clamp holds the tank on making removal very easy. Remember any water that gets in will go right to the bottom and start rusting the steel tank from the inside out. It is usually found out the hard way, when you try to remove the drain plug and the bung twists right out of the tank!

V-71 - The V-71 is a downsized unit with smaller double acting rams that is ONLY used on the Super VLD-7.5 as of this writing. Originally, the Super VLD-7.5 used the V-70, but it was quickly replaced by the V-71. the V-71 also has its own controller that will not work with any other Meyer hydraulic unit.

V-70 - The V-70 replaced the V-68. It is another unit built by Bucher for Meyer. Like the E-72 it too has the plastic tank, and hard plastic pump cover. It was used on the Super V, Super V2, and in the beginning, the Super VLD-7.5. The 22695 (22695DC) controller will also work a straight plow. Naturally only the raise, lower, left, right, and HFP (if connected on vehicle) will work. The wing buttons will do nothing.

E-73 - The E-73 is the hydraulic unit used with the new Meyer SOS. SOS stands for Standard Operating System. By 2018 it will be the ONLY operating system Meyer offers on new plow systems. As of 2017 only straight plows come with SOS. By 2018 V Plows are supposed to switch to the SOS too. the E-73 is just an E-72 turned horizontal. It still uses the same A, B, and C valves, with the same functions, it is just wired differently. The SOS will evolve quickly as it seems to me it was rushed to market. It came out in 2015, and there have been many changes to it already. I did create a page for it, and while it sounds like I hate it, well I do, BUT there is hope. IF you wanted to scrap all the SOS wiring, you could wire it up with the 1 piece plug universal wiring. the E-73 itself it the same as the E-72 as far as what Valve does what.

10-4-17 Meyer Standard Operating System information. Also known as the SOS.
It is now standard for all Meyer straight plows.

Because I am sure some reading this won't look further for more information (it seems everyone wants an instant answer these days) I will add some details about these units here. The E-47, E-57, and E-60 were also available as H Models, so E-47H, E-57H, E-60H. The H Models have an 8" stroke. Standard models have a 6" stroke. H Models were never used on the EZ Custom / Custom Classic mounts, nor the EZ Classic ("the tube mount" as many call it). There is one exception to the EZ Classic in that the Diamond version of the EZ Classic was called the "Pull Away" and it ONLY used H Model hydraulic units. It also had two lift chains. ALL MDII and EZ Plus mount plows use H Model hydraulics. The MDII stands for Meyer Diamond 2. This was the first shared mount by both Meyer owned brands, Meyer and Diamond. Today, diamond has been fully absorbed by Meyer, with the only remnant is that the trip edge straight plows Meyer sells are called "Meyer Diamond Edge". Meyer straight plows are all "Pro" plows. Lot Pro, Road Pro, Drive Pro, Path Pro. In 2017 Meyer went full bore with their new SOS (Standard Operating System) plows. They are very confusing, because they use the EZ Plus mount, but they are SOS. The SOS is the hydraulics and wiring, and they are now using EZ Plus to designate the older operating system, meaning the universal 1 piece plug system that was all they used from 2008 - 2016. As outlined above, the SOS uses E-73 hydraulics.
