The following items are applicable to this modification:

AMENDMENT NOTES

1. The purpose of this amendment is to answer questions and extend the closing date as follows:

a. The closing date has been extended from 11-Jun-2018 10:00 AM to 18-Jun-2018 10:00 AM.

b. The following questions were submitted and answers are as follows:

Question 1: Need to know flows for the motor test and displacement of the UUT. Usually they have pictorial diagrams of how they want things set ups as well.

Answer 1: There are two types of UUTs. One is a hydraulic pump, and the other is a hydraulic motor. In the case that multiple part numbers are given for a pump or motor, there is actually only one pump type and one motor type.

Multiple part numbers are given when there are multiple sources for the pump or motor.

UUT Displacements

To determine pump UUT displacement, I suggest using the speeds and flows from paragraph 3.2 in section 13.1 of the SOW. I calculated using all combinations of speed and flow and averaged the results. This gave me a displacement of 2.01 cubic inches which is close enough to the actual pump displacement.

The motor UUT displacement, 0.950 +/- 0.05 cubic inches, is given in paragraph 3.4.3 of section 13.2 of the SOW.

UUT Flows

To determine maximum motor UUT flowrate, I suggest calculating it from the motor UUT displacement and the highest speed given in the test procedure during a test step. The motor UUT displacement, 0.950 +/- 0.05 cubic inches, is given in paragraph 3.4.3 of section 13.2 of the SOW. The highest speed is given in paragraph 3.3.1 of section 13.2 of the SOW and is 4,800 +100/-0 RPM. The calculation results in a flow of 20.3 GPM.

Regarding hydraulic schematics of systems to test the pump UUT and motor UUT, we have these, but distribution is limited. We would not normally provide this regardless of distribution requirements, because we do not want to prescribe or dictate a specific design capable of meeting all SOW requirements. After contract award, the winning bidder will have access to our existing test stand, so they can review the design.

Question 2: Section 13 of the SOW: we need physical dimensions and performance characteristics (specifically displacement) for the UUT items listed in drawings #12287040 and 12285278. We understand that these drawings are not available but we cannot size the test stand and mounting interface hardware to connect the UUT items without this information.

Answer 2: Drawings 12287040 and 12285278 are source control drawings for the same pump from two different manufacturers. There is only one (1) pump design and one (1) motor design. We are not able to provide physical dimensions. I would assume the pump is similar in size and layout to a commercially available axial piston pump of the same displacement. Regarding displacement of the pump, please see my response to question 2 above suggesting calculation of displacement from speeds and flow rates given in the SOW.

Question 3: A written description is fine, assuming the shaft and flange (typically an SAE standard pattern) of the UUT components are detailed. If they are non-standard we will need specific details on the dimensions and configuration.

W911KF18Q0039

Answer 3: The drawings that will be provided after contract award provide sufficient detail to design a machine interface to the pump shaft and flange. I would assume that a custom design will be required.

Question 4: Also, same question on the hydraulic connection ports. Typically they are an SAE standard configuration. However, if they are non-standard we will need specific details on the connection.

Answer 4: The drawings that will be provided after contract award provide sufficient detail of the hydraulic port connections which are per MS33649.

2. All other terms and conditions remain unchanged.
