    motor removal

    so having never done it before on the hawk...

    how hard is it really?
    i dont NEED to remove it for anything mechanical.. but i kinda want to paint the motor...

    i know someone made a nice step by step.. but im far too overenthusiastic to read it as i go.... so assuming i pull the carbs and chain off... can i just yank the motor mount bolts out or what? lol


    also how heavy is it? my jack is loaned out to someone.... so i'll be rigging something stupid up. lol.

    Removed my engine last fall, not to hard to do, but you do need a floor jack and some special tools( swing arm pivot bolt). I manage to remove it by grinding a socket, but now I am stuck for re-assembly( need the proper tool to torque that pivot bolt).

    MrDude_1 I wouldn't take the engine out of there only for paint, but thats only my opinion.


    Thanks
    Its not gone yet and I already regret selling it.

      ya sounds about right

      the electrical harness will get in your way

      and yes the pivot bolt requires a special tool (I made one, just like im making one now for the clutch basket) its an odd tool so finding something else that would work will be hard to find. the other two are easy to pull out.


      I would say the motor is about half of the total bikes weight you can slide it around but lifting it might give you a hernia or something.

        i dont really want to take the motor out only for paint either... but i want to be sure it comes out great.... only way i know to do it perfect is to pull it...

                i found it, and i googled the part number...

                really looking at everything, i think im just going to dremel an old socket.

                  When I took my engine out I jacked the bike up and then built a stand out of blocks of wood under the sump. Undid all the mountings and lifted the frame and forks over the engine. Installation was the reverse

                  I made swing arm lock nut from an old 1/2 drive socket

                      Yeah I just got the motor back in my hawk this weekend. I blocked the centerstand and front wheel up about 4 or 5 inches when removing and installing. I would block it up higher if I did it again. My jack is a little thick though. The painful part for me was getting the front head past the cross member thing on the front of the frame, seems like you have to pull the back of the motor down first and get the front head out last. Reverse for install. Definitely helps to have another person. For the install my brother and I actually lifted it off the floor initially to get the front head in right and then rolled the jack under and set the motor on it. I would say the motor weighs about 125-150 pounds.

                      Here is a link to the tool I used for the lock nut. This is not the honda tool. I couldn't find the real honda one. The honda one allows you to hold the allen while torqueing the lock not, this one does not. I faked it.

                        Correct me if I am wrong but if you are not holding the bolt while torquing that lock nut, is it possible to load up the needle bearing that sits on the other side?

                        I called the dealer for that tool today and they are asking big bucks for that tool, 105.00$ Canadian dollar. I might try calling an Acura dealer as they use it on the Acura NSX drive shaft I think( the exact part number).
                        Its not gone yet and I already regret selling it.

                          here is the tool i made

                          used a mill and a lathe and a press to make all the parts but i works prefect
                          and this will give you the ability to get a torque wrench in there

                          if you still want that swingarm i can let you barrow this

                            You are correct. It is definitely possible to over torque the allen using the tool I did, which could distort the spacers, load the roller bearings etc. ... so I do not recommend this as the preffered method. The tool jaysun0ne looks sweet, if you can borrow his, make one or buy one, that would definitely be better. I didn't find one in my searches.

                            What I did ( the wrong way ) in an attempt to avoid turning the allen while torqueing the lock nut, was to torque the opposite side pivot nut before the lock nut. This is out of order from what the manual says. So the full list of steps I took is ... torque the allen to spec, torque the opposite side pivot nut to spec while holding the allen. Torque the lock nut ( to actual not "indicated" in manual ) and then recheck the torque on the pivot nut. In my case the lock nut didn't go far before it torqued down. I feel pretty confident I didn't over torque the allen, but there is certainly a chance. I didn't but you could also mark the opposite end of the allen bolt or the allen bolt/lock nut to see if it turned.
