    Default Brake cam actuator

    How do these work. Hit the clutch spring and release the brake on a Whirlpool direct drive?
    Have one with an open end on the cam. Wondering if this causing the brake to not release and making the clutch slip causing a no spin situation.
    Most of these cam actuators seem to have a closed end.

    Hi,

    Picture is here.

    A clutch drum and shoes (mounted atop the transmission) allow the basket to come up to speed slowly during the spin cycle. The clutch drum rotates and is driven by gears inside the transmission. Similarly, a set of brake shoes (attached to the spin tube) contact a drum (attached to the bottom of the mounting pedestal) to provide a basket braking action to the tub whenever the washer is NOT in the spin cycle.

    Changing between the agitate and spin cycles is accomplished mechanically within the transmission when the motor reverses.

    This what most look like...

    That actuator looks like it has a closed end and is above the pointed part like most I have seen.
    The one I am talking about if open ended and no longer than the pointed part.
    I have another used brake spin tube I looked at for comparison. It looks the same as the one I am asking about bit has what looks like it may have another piece on the end where there is an impression of 2 small studs. May be mold marks.
    On this particular machine, the clutch is slipping, and I cannot turn the basket by hand. Don't know if the brake is not releasing or if it is the granny.
    Was thinking maybe the high part of the actuator was supposed to engage the clutch and release the break allowing the basket to spin.

    I got around to checking thing again.
    The c l itch was slipping. The pads were actually fairly worn down. That plus a little oil from the spin tube had gotten on the clutch pads.
    Not sure how the oil got in the spin tube housing, or why I could not turn the tub by hand. The transmission turned freely by hand when removed.
    Anyway, I changed the clutch and brake assembly.
    Seems to be working ....for now.
    I noticed it would spin with lid up. Thought I had some new lid switches but could not find any.
    Apparently the lid switch Had shorted while the clutch was slipping and the drum would not turn. Out of curiosity, I took the lid switch apart and "fixed" it.
    I think I had put it in New.. Time to order more of that type switch.

    Yupper!
    I hate when I can't find the part I am looking for and swear I had 1 or 2 in stock.

    Traveled up the tranny shaft maybe.
