    The front casters on these units are a weak link, they cost $146 each and there are six of them. Our crew leader, Jeremy Davis came up with an idea to recondition the yokes. He uses an aluminum rod the same diameter of the original hole and welds steel in around. The steel will not stick to the aluminum, so he is able to recondition the hole.

    I have had them snap off at the shatf, where it's welded to the fork, but only two of them. I think the operators had stuffed them in a hole while mowing. I just welded them back up and never a problem. We have about 700 hours on ours, and have no signs of wear like your photos show. How many hours on those units? I would say all in all they are good units. I did slow ours down a bit so the decks are not bounching when they're driving accross the course or mowning rough. I did mention to Deere that I would like to see them with the same caster setup as they have on the 8800.

    Any ideas???
    7400 when you start the engine it starts and then dies right away
    We replaced the brain box and have tested all relays for correct voltage
    If we disconnect the fuel shut off cylanoid the machine will stay running
    Just looking for ideas or suggestions.

    Thanks

    It is spelled
    Solenoid
    I know that didn't help but couldn't resist
    What does the voltage read to the fuel shut off?

    found this old notice online... hope this helps
    Solution Number: 8113

    Solution Summary: PIP 96RW128 FUEL SHUT-OFF SOLENOID IMPROVEMENT / FIX-AS-FAIL

    Publication Date: Aug 4 2003


    --------------------------------------------------------------------------------

    **Paper copies of solutions may not be the most current solutions**

    This PIP has terminated, and PIP claims will no longer be accepted.


    COMPLAINT:
    * - Engine will die and not restart.
    * - Engine may exhibit low power or run rough when hot.

    PROBLEM:
    All tractors have higher than expected fuel shut-off solenoid failure
    due to manufacturing problems with plastic bobbin that the wires
    connect around. Tractors within a known serial number range are
    suspect.

    PRODUCTS AFFECTED:
    For reference, tractors in this program will be within the following
    serial number range:

    5200 (220563-420322), 5300 (230622-430831), 5400 (240597-460190)
    6200 (109272-134969), 6300 (109272-134969), 6400 (109272-134969)
    7200 (001002-003130), 7400 (001002-003326)

    CORRECTION:
    Install MPCD10021 Shut-off Solenoid Kit on 5000 and 6000 Series
    tractors or RE54064 Shut-off Solenoid on 7200 and 7400 tractors.

    SPECIAL TOOLS:
    None needed.

    KIT INFORMATION:
    All kits/parts are to be ordered from PDC. They will not be
    automatically ordered for since this is a Fix-as-Fail program.

    LABOR:
    Install shut-off solenoid kit/part: 0.5 hrs.

    ACCOUNTING:
    Please prepare DC-255 for each tractor repaired in this program.
    Make sure that tractor model number, serial number, program number
    and factory account code number (09-492) are on each claim completed.

    EXPIRATION DATE:
    01 April 1998

    DISPOSITION OF PARTS:
    Scrap all replaced parts using service administration guidelines.

    ADDITIONAL INFORMATION:
    Another way to identify suspect solenoids is as follows;

    Before installing new solenoid, check for 'Lucas/Cav' manufacturing
    code rather than 'Roto-Diesel'

    Solenoids can be identified by a four (4) digit code stamped on the
    body. First two (2) digits indicate week number and last two (2) are
    the year. For example; Code 1594 means week number 15 (11-16 April)
    of 1994.

    Do NOT use any solenoid with manufacturing codes from 1293
    (22-27 MAR 93) up to 2694 (27 JUN - 02 JUL 94).

    Any parts with single upright stud are probably 'Roto-Diesel' and
    should not be used. Unpainted pieces will say 'Roto-Diesel' on top
    cover near stud. 'Lucas/Cav' pieces have flat top with threaded
    hole.

    Solenoids in your inventory with codes between 1293 and 2694 or from
    'Roto-Diesel' should be returned to your parts depot using regular
    parts return procedure.

    IMPORTANT:
    Under normal operation, shut-off solenoid can be 'HOT' to the touch.
