  • Crank Pulley?

    Ok boys and girls, here is one I have not seen in my 50+ years of playing around with the Model A. It is a 2 piece crank pulley, but as you can see, it is not like the normal 2 piece. The pic on the left is the back of the pulley and the 4 indexing nibs for lack of a better word. The pic on the right is the end of the crank with a collar around the actual crank and the 4 indexing detentes.

    Without pulling the pan, how the hell am I suppose to remove this so I can replace it with a 1 piece pulley? There is no discernible lip to grab hold of and as you would expect, the damn thing is rust welded to the crank!

    PS. The reason I am replacing this is because it has a weeble wobble and now that I see it in hand, it is a 2 piece stamped and riveted pulley. *shudders*

    HEY, Hold da phones!!!

    Got that bad boy out with a leetle tappy tap of the 4# hammer and a pair of vice-grips!! Whew, had me goin for a minute.

    Now to wait til tomorrow as the sun is in me eyes and can't see squat.

    Hey, can I jack the front of the motor with only removing the top rear motor mount bolt and loosening the bottom, or do I need to pull both rear bolts/side?

      When the new pulley goes back on, make sure the keyway is exactly lined up. The engine I'm working on now had a 2 piece pulley, and some fool just jammed the sleeve and pulley on, which forced a new keyway into the aluminum sleeve, and cracked it.

        I'm glad you got it off
        i had a stubborn one once so i lifted up the front of the motor then took my wizzer and scored the sleeve all the way around. i then used my small clam shell / bearing puller to remove it...

        i usually pull one bolt on each side and then loosen the other for the assy to pivot.

          Yea, I had my inside/outside puller ready to pop it off until I found what you see. What a shock that was. I haven't seen one of those before, but then, this car is from Michigan.

            It only took you about 1/2 hour between post to get it off, good for you! Two bolts out, two loose and you should be ok, I would watch the linkage on the back of the engine ;-)

                Well, after posting the question, I went again and looked a bit closer. I am thinking I need about 1½ to get the new pulley on so I might take all the rear mount bolts out, just to be on the safe side. See, this frame is surprisingly straight and I wouldn't want to kink it or possibly break the flywheel housing. Always better to be safe than sorry.

                  When I had to lift the front of mine I took all the bolts from the flywheel housing to the mounts out. Also removed the throttle linkage before I started. Check your brake and clutch pedal for clearance as well the park brake. Not sure what model year you have but mine is an early 29 that has the rear trans housing with a lip that hangs the crossmember.

                    I have a July '28 Tudor that has the same lip and I think I have enough room to lift it the required distance without bending anything. See, I was ahead of the game when I removed the spring clamps and crank guide, that cut about an inch off the height needed to get the new pulley on.

                    Now I am wondering, I don't remember if there is suppose to be a washer between the bolt and pulley?

                    Damn, it is hell getting old and loosing those important braincells.

                      Some suppliers have a 2 piece pulley that screws together with a L/H thread. Looks stock & easy to install!
                      To get a stock one off, pull it forward & cut it off with a Saws-All, EASY!

                        there ya go that's an option.

                        i know a guy that saw zawed his waterpump in half to avoid messing with the radiator. He then used the fake water pump studs when reinstalling the new parts

                      In additions to all the suggestions above, I would recommend that while you spend this much effort and time, that you go one step further and go back with a new steel one piece "billet" crank pulley. That way you can be done with that forever.

                        2 piece Crank Pulley
                        by 1930 Closed Cab PU
                        The Model A shop working on my A called, prefers to install a 2 piece Crank Pulley.

                        Searched here and seems the 2 piece can have an issue if it can not be tightened down correctly. The fix is a spacer washer.

                        So if tightened down properly are there any issues? Or do I insisted on the left hand threaded 2 piece Crank Pulley?

                        Seems to me if there is an issue...

                        Crank pulley failure
                        by tbirdtbird
                        In the most recent issue of the Restorer (May/June) that just arrived there is a story about the failure of a new one-piece crank pulley.
                        You can see from the pictures that the failure involved the slot for the woodruff key, and there were new splits forming from what remained of the slot.
                        The presenters seemed to be somewhat mystified as to what could have caused this, and no explanation...

                        by Art Ebeling
                        I told my 87 year old buddy I would put a new radiator in his 30 coupe which has overheated all summer. Of course one thing leads to another. With the radiator removed it is clear to see the crankshaft pulley is broken. Is this a one or two piece pulley and will it come off without raising the engine? Thanks, Art...

                        Am thinking of changing out the front 1 piece pulley. We used to break off the c.i. spokes to allow removal without removing the radiator, etc. I have a 2 piece pulley in the parts stash that appears well made but also researched that Sacramento Vintage Ford sells a threaded 2 piece that may be less prone to breakage, etc. Has anyone had experience with the latter, putting aside that some owners ...

                        I'm in the middle of replacing my radiator and water pump and crank pulley. The nut on the old pulley is not breaking loose. I've put the crank on a jack stand to keep the motor from turning over but still won't break loose. Any ideas? It is lefty lucy isn't it? Thanks Bob

                        I can grab a fan blade and turn the crank pully a half inch back and forth without moving the pully ratchet nut. In other words the ratchet nut does not seem tight against the pully. The pully was replaced by the engine builder at my request. It was originally a 2 piece pully. Also the front seal leaks oil big time. Engine has a new Burlington crank if that makes any difference.

                        by JtownJoe
                        So I got the new 2 pc. crank pulley, (threaded type) to avoid pulling the radiator, and I am removing the cam shaft cover and then dropping the pan at least enough to install the new oil slinger. I am assuming there isn't one on the crankshaft now, since the old one broke at the offsets and the ratchet nut was very tight on the pulley, is there anything else I should know? I have the Les Andrews...
