    1. What is the Accumulator

    A lot of MT cars / trucks come with some type of accumulator that messes with the clutch feel and engagement. This is said to help newbs learn to drive an MT and reduce shock and wear on the driveline. For anyone that knows how to drive an MT will laugh at this. The last thing anyone needs is system that doesn't follow your commands, is slow, and is inconsistent.

    Removing the accumulator will add some feel to the clutch, speed engagement when you want to, and allow you to modulate the clutch effectively when you need it, such as when downshifting to 1st while moving.

    If you want more feel, faster / direct engagement, and less wear, the ADM is for you.

    :cheers:


    2. Plug and Play Delete Kit!

    @Trident904 is fabbing formed hard lines including the coupler for this delete:

    3. Flare Explanation

    Very good info on our flare type:

    4. @sherwoods_Fleet Installation Instructions

    Sorry for splitting up the installation details, but @sherwoods_Fleet 's instruction are too nice to bury further down. Of coure, the PDF is attached at the bottom of this post. I know how to link it right here.


    5. Clutch Accumulator Delete Options:


    6. 12in Prefab / Salvaged Hard Line and Coupler from autoparts stores / online:

    This is arguably the easiest method, using either scrap brake line or a 12in prefab line (3/16in double flare with M10x1.0 fittings, and an M10x1.0 coupler).

    Here are the parts that @Trident904 used:

    9. Brake Line Elbow Mod

    This is the route that @RedBeard1 and I went. Thanks, @RedBeard1 for confirming that this should work.

    I safety wired mine, while @RedBeard1 welded his to the original mounting plate:
    IMG_20180914_153246.jpg

    My plan was to use some heat to twist the bracket 90deg for mounting. Edit: don't use heat. It isn't needed.


    Mods to the elbow:

    Original Part:
    IMG_20180915_103312.jpg

    Flattened the mount bracket as much as possible without a vice:
    IMG_20180915_110129.jpg
    The mounting hole didn't align well.

    I thought a twist might help:
    IMG_20180915_131225.jpg
    Nope! Other than giving a nice perch for the safety wire.

    Final setup (the top side is to the right):
    IMG_20180915_140140.jpg
    I had to cut off the bracket that extended past the plate so that it would fit on the transmission.


    10. Installation details:

    I clamped off the inlet line just in front of the firewall.

    IMG_20180915_110513.jpg

    I highly recommend removing the exhaust support. It is just 3 14mm bolts, makes dealing with the shield much easier, and allows the use of a straight 10mm line wrench. HF, FTW! My 12pt articulating 10mm was hosed up and almost rounded off the nipple. The HF ones are 6pt.

    3 12mm to remove the accumulator from the transmission. I removed the accumulator (4 10mm) and reused the mounting plate.

    Safety wire!

    I bent the slave line up then back to flex it in to place. I then used various tools to gently flex the slave line away from the mount bolt and transmission.

    Note: Get both nipples started by hand as far in as you can before tightening with a wrench or flexing the lines around for final alignment. You really don't want to cross thread anything here.

    IMG_20180915_144038.jpg

    Bleeding was a piece of cake. It seems that the only air in the system was near the slave. Bubbles didn't seem to travel up as the supply continued to trickle?

    Driving, there is a bit more feel. I will post up once I get more miles.

    11. Adding accumulator pics:
    IMG_20180916_114112.jpg

    IMG_20180916_114047.jpg

    IMG_20180916_114027.jpg

    IMG_20180916_114009.jpg

    The circular wire is not a clip. It is a spacer to add preload to the plate and seal.


    12. 2.7l Clutch Line Diagram

    Here it is:
    upload_2019-2-13_8-45-46.jpg
    From toyota.com

    These are all the lines from the firewall to the slave cylinder. It looks like a very different routing. I do not think that Part Numbers 31482 or 31482A would be of any help with the ADM.


    13. Hey, @7r41lbr34k3r .

    @TeecoTaco thinks that his life isn't complete without some shiny new Ti Radio Knobs. For him, just one of your knobs is not enough. He needs all the knobs.

    Not that I have a manual transmission, but out of curiosity, what’s does this do?

    It goes in place of the accumulator to maintain the existing turn. Standard elbow instead of the gizmo.

    The accumulator decreases clutch throw, slows engagement, and kills most of the feel of the clutch grabbing.

    definitely watching this one. long-term this is one of the main things needing a fix.

    the unfortunate thing is I've got about 10 other super annoying things needing a short term fix before i can enjoy any of it.

    Definitely watching the progress of this project. Will do ASAP if all goes well.

    It appears as if it will be reversible for warranty work too, eh?

    Thanks for posting it.

    It should be very reversible.

    Unless they are touching the clutch or transmission, there's no need to worry since it is hidden under a heat shield.

    TY for doing this Tony, very interested in the outcome.

    Since I have no experience bleeding a hydraulic clutch, could you include tips/tricks in that regard if you have time?

    Again, thanks!

    Here's the little beasty:

    I noticed that the removal procedure in the SM said to remove the front driveshaft... hoping that can be worked around.
