    HIGH PRESSURE FILTER

    SAE J514 is the hydraulic tube fitting specification which spans SAE-ORB and pipe fittings. Assuming the port on the filter could possibly be an SAE J1926-1 straight thread o-ring port since they specifically call out straight thread and not pipe thread. Since your port size is 1-1/2 inches...

    HYDRAULIC FITTINGS

    I second the Parker recommendation. I get all my fitting models from the web site. Just do a search on the fitting type, C5FOX, and you will be directed to a page that you can select your size from there you will then be able to download the model if it is available. If it is not available...

    Jounce & Squirm

    I guess I am talking about the ingress/egress test... It has been sometime... Maybe the one your looking for is the loading of the butt form directly into the seat cushion, rotating it ±30°, and then removing the load. I vaguely remember a test being performed according to that method, I...

    Jounce & Squirm

    I'm not sure that the test is required by the Feds and SAE only provides standards for best practices. When I use to do the testing it was more for fabric and cushion durability evaluation/integrity and not an FMVSS requirement, those are safety standards and what you are looking for is more for...

    "Thread stuck in device driver" error

    Open the case and check the capacitors around the CPU. If they are domed, they are bad and must be repaired or the MB replaced. I've replaced five MBs at work due to bad capacitors and they all exhibited the same issues you describe, coming to work in the morning and finding a BSOD on a PC...

    fuel tank baffles

    Why not a fuel bladder or cell with a foam insert? The foam will reduce the amount of slosh.

    standard stresses on suspension parts?

    My 3g vertical and 2g fore/aft that I referred to was not soley based upon the unsprung mass, but the corner weight of the vehicle. Though I do agree 4/5g vert and 2/3g fore/aft would be more reasonable for pothole events, but I must disagree that the lateral load is do to the reation of the...

    standard stresses on suspension parts?

    Typically you start with a 10 to 100 occurence loading of 3g vertical and 2g Fore/Aft through the center of the wheel to simulate a pothole event. Also working with 1g lateral loads for cornering and max braking loads in forward and reverse driving directions, which can be upwards of 10,000...

    Hydraulic Hose

    My concern is that your bend radius is to tight for a -06 hose. From my information (see also http://hydraulics.goodyear.com/cfmx/web/hosesearch/hose_family_results.cfm?hosefamily=GR12 ) the min bend radius is 5 inches for a -06 hose. You will cause damage to the hose with a 4 inch bend...
