Hey guys, its Seth here and this is an overview of the Parker 10cc hydraulic pumps. I'm going to try
and cover some of the details of these pumps so there is not so much confusion as to what they will fit.

From what I have learned the Parker hydro pumps are a copy/imitation of the Hydro Gear 10cc pumps (which have been the industry standard for most of the commercial lawn equipment for years). It is
a design meant to replace the hydro gear pump at a cheaper cost. From what I have seen Parker has had a few different generations of this pump including the H110 series from which they had several problems and there may be a H210.
After they found the problems they re made the pumps, thus the H310 series.

We have had good experience with the H310 series pumps. We have replaced many different types of hydro gear pumps in many different makes and models of commercial lawn equipment and they have always performed well for us. The input and
outputspecs are the same as the 10cc hydro gear pumps but there is a little difference in the port locations on the pump. This makes it necissary in certain applications to get longer hoses and different angle fittings to make the pump work.

From what I can tell there are 4 different types of the parker H310 series pump and they are as follows:

1. Parker H310A right hand w/RTN (this would be for mowers with the return to neutral set up and this would go on the right hand side of the Wright stander)

2. Parker H310A right hand w/trunion arm (this would probably be your most common pump fitting on such mowers as the exmark lazer z, lz hp etc)

3. Parker H310B left hand w/RTN (same as H310A w/RTN right hand except it is the oppisite side for such mowers as the left hand side of the wright stander)

4. Parker H310B left hand w/truntion arm (same as the H310A w/trunion arm right hand except it is the oppisite side for such mowers as the right hand side on exmark turf tracer wb mowers)

Out of these 4 types of parker pumps you can fit a verrry wide range of the hydro gear brand pump. There are however a couple more things to make certain of.

First of all you need to figure out what the shaft rotation of your pump is (is it a clockwise rotation or is it counter clockwise) CLICK the link above that takes you to the hydro gear manual with all the different hydro gear models and
go accross the chart to see what your rotation is. (the parker pumps are a counter clockwise rotation so if your hydro gear pump model matches with "CCW" this pump should work in your application!

The only other thing I have noticed is that on some of the hydro gear pumps they have a different main shaft configuration. Most are the strait long shaft with keyway but some are the short shaft with splined end. You may be able to use
the parker pump in either application as long as you can configure your pulley design.

How to tell what side pump you have:

Look at pump from an angle where the two main hydraulic hoses/ports are pointing towards you then simply see what side the control linkage bolts up to. If your control linkage bolts to the left side you have a left pump if your linkage
bolts to the right side you have a right pump. Simple.

The last thing I would like to say in this video is that before installing ANY pump on a piece of equipment you need to make certain of why there was a problem with your hydraulic system in the first place. If the bearings went out in the
pump and led to metal shavings... this means that your complete hydraulic system is contaminated and at risk. If this is the case and you decide to just buy one pump and replace it you will without a doubt ruin your new pump from the contamination
in your system and this is not covered by any warranty.

Thanks and have a greeat day!
