    Default Engine replacement...

    Well, need to replace my 5.7. I have a question about pulling the old one. Is it only the 6 bolts holding the engine to the Flywheel housing? Will the engine lift straight up or does it need to go forward first? Will there need to be any aligning done when new engine goes in. Also, I want to change out any bearings that Are there when the engine is out. Can anyone tell me what/where this/these bearings are. This is my first Volvo drive, always had Mercruisers.

    Thanks in advance,

    Correct...... there will be 6 bolts holding the two together.... sometimes 7 if the top hole is used.
    There will also be a dust plate on the lower FWD side of the flywheel cover..... 5 small screws if I recall.

    Will the engine lift straight up or does it need to go forward first?
    Pull the 4 lag bolts from the side engine mounts, leaving the mounts attached to the cylinder block.
    The engine needs to slide FWD just a few inches, then it can be raised up.


    Will there need to be any aligning done when new engine goes in.
    There is a triangulation procedure that you can do.
    Do a forum search.... I've posted on this many times.


    Also, I want to change out any bearings that are there when the engine is out. Can anyone tell me what/where this/these bearings are.
    That was next on my list to mention.
    Yes.... PDS bearings and seals.
    Your flywheel cover PDS requires industry standard 6206 and 6007 bearings, and two 35x62x7mm seals in a Timken or TCM brand.

    These are industry standard parts that can be sourced by a good bearing supplier, and for a fraction of what VP wants for the exact same parts.
    Be sure to pre-fill the grease cavity before installing the FWD seal.
    Glue or stake the AFT seal in place so that grease gun pressure cannot blow it out of position.

    This is my first Volvo drive, always had Mercruisers.
    You'll like this much better.

    Thanks in advance,

    Do the outdrive splines thread directly into the flywheel? if so, removing that would shorten the distance forward required to remove the engine.

    You will have to take the outdrive off anyway in order to do the alignment once the new engine is installed. good time to replace the gimbal bearing and bellows, too.

    No!
    The out drive itself has a universal drive shaft attached to it.
    The FWD section of the universal drive shaft has a female yoke attached to it.
    That female yoke slips onto the AFT end of a PDS (primary drive shaft).
    No threads.... slip splines only.

    The FWD end of the PDS is also splined.... i.e., Borg Warner splines.
    Those B/W splines slip into a Borg Warner drive coupler.
    The Borg Warner drive couple is attached to the flywheel.


    if so, removing that would shorten the distance forward required to remove the engine.
    The PDS is held into the flywheel cover by snap rings.


    You will have to take the outdrive off anyway in order to do the alignment once the new engine is installed.
    No.... the one-time alignment involves a triangulation process. (I will explain the process to the OP if need be)
    The drive can be in place while doing so.


    good time to replace the gimbal bearing
    The AQ series drives are main suspension fork and pivot tube geometry...... no Gimbal suspension... no Gimbal bearing.

    and bellows, too.
    Yes!

    Thanks, Rick, when I said threaded, I should have said inserted. I did not realize those splines did not directly connect to the crank. I have an SX and was unaware of how the AQ worked in relation to the gimbal bearing.

    Correct........ the SX uses a gimbal system suspension, whereas the AQ series does not.

    You will have the double bearing PDS.
    Just remove the transmission and do this while the engine is out.
    Your flywheel cover can remain attached to the transom shield.

    Do a search using my user name...... you'll find quite a few threads and images regarding this.

    Here are several images that will help you.

    Your set up has the red 1pc flywheel cover with the double bearing PDS.
    Unfortunately, the engine must either slide forward enough, or be removed, in order to access the front area of the F/C.

    Here are the components in their respective order.

    You will need a loooooooong needle nose plyers with the tips ground round, and tweaked in a bit.
    This is done so that the tips will fit into the snap ring eyelets and not slip off.
    Trust me...... no factory made snap ring plyers works as well!

    NOTE: with the FWD seal glued/staked into position, and with AFT seal not yet installed, spin the PDS while you pump the grease cavity full of a good high pressure bearing grease.
    Install the AFT seal only after you have seen new grease exit the 6206 ball cage.

    This purges any air from the grease cavity ensuring that 4 to 5 full pumps in the future will actually replace the old grease.

    Grease these during each engine oil change, and with engine at idle speed.

    Pop the upper off the drive and pull the bell with the engine block. Do it right.

    Chris, this an AQ series drive.
    Although it can be done as you suggest, there is no need to remove the flywheel cover from the transom shield in order to replace the PDS bearings and seals.
    I've done this successfully many times.


    If we do remove the engine with the F/C attached to it, and then pull it and put it on the work bench, it does make the task a bit easier.
    But certainly not enough to warrant it.
    It would also require at least one new rubber cushion ring (at the interior).


    Either way works.
    It's the OP's call.

    So, if I wanted to take the whole thing out so I can work on the bearings on the bench... I put the f/w housing bolts back on, what do I need to disconnect to take the whole thing out? The boat is shrink wrapped right now, so I can't see. I know I will need a rubber ring or 2. but would like to know the process. Where does it need to come apart? I would just like to know what I'm in for. Pictures would help... BTW, I was making a joke about the head.

    Why?
    If you want to pull the engine w/o the F/C attached to it, pull the engine by itself.
    You can then remove the F/C from the transom shield.


    what do I need to disconnect to take the whole thing out? The boat is shrink wrapped right now, so I can't see. I know I will need a rubber ring or 2. but would like to know the process. Where does it need to come apart? I would just like to know what I'm in for. Pictures would help...
    You will need to:

    Remove the transmission.
    Remove the 6 clamping ring bolts.
    You will see the 3 jack thread holes (the locking plates cover them up)
    Next, clean these threads out and lubricate them.
    Run clean bolts into each jack thread hole.
    Tighten them equally, one turn at a time, and the clamping ring should back itself out.

    If it does not, post back for more info.




    BTW, I was making a joke about the head.
    We figured so.


    NOTES:

    ..... the 2 rubber cushion rings provide the rear engine isolation... i.e., engine mount.

    ..... the inner cushion ring provides the water seal between the F/C and the transom shield.

    ..... the rubber cushion rings will have taken a "set" by now, which means that the front ring should be new.

    ..... there is also an alignment (involves a triangulation procedure) that should be checked when going back together.


    Example.... yours will look slightly different.
