Just thought of something i have done before. Take a piece of tubing / hose that is straight & cut off true, couple inches long. Put some sealant that is oil / gas resistant around bottom of tube. Fill it up with your penetrating oil, I use deep creep by seafoam. Let it sit, so the lube has time to go down around the taper & key-way in flywheel. This keeps it from running all over the place. Could work for you. interesting idea. while i'm ordering the nut i'm gonna try this. thanks! |

glad you mention that. i'm back for round three as i haven't gotten it loose yet. and those items you mention were on my question list... note the two smaller bolts to the side of the large center bolt on the puller, one has started to bend a bit. not sure how much tighter i can crank down.
i have had to walk away a few times due to frustration. hence why this is taking so long. lol
for my questions: q1) for heat are you using like a small propane torch or a hot-air gun? q2) you are heating the puller bolt, yes? from the top of the puller bolt or where the puller bolt meets the shaft? q3) "nut on the crank", you mean the rotor nut or just some surplus left threaded nut? the rotor nut has bearings in it, i'm a bit leery to whack it.
Uh oh, I didn't notice that was a 150! Apologies because if I'd noticed that, I wouldn't have said what I did about the nut. So far, I haven't found a left hand threaded nut to fit. No local hardware stores around here have them. Seemed like I determined the size and maybe found one at McMaster Carr or somewhere but never ordered one. Maybe someone else has a good source, but it stumped me. The last couple I fooled with, just found a piece of flat iron to fit between the crank and the puller bolt so it wouldn't rotate directly on it, and luckily they came off easy enough. Dan
no worries.
i'll check a bunch of online sellers and maybe luck out and find one. you and another here mentioned putting "something" in between the crank and puller bolt. i wasn't sure that was ok to do until you mentioned it. the puller bolt is tapered so i had thought something in between might mess up those crank threads. i see that is not the case. if i can't find a LH nut i'll try a piece of flat iron. appreciate the help.

Go to home page, Click on HoH help center. On search type in flywheel removal. Should be third one down. Thread from 2018. Some good information there. Heat? Be careful, could ruin seal. As other posters said, take your time. I haven't had trouble removing the ones on my 150's.Hope this page will give you some good information. thanks. i will head over there and read up. had wondered the same regarding the heat. appreciate your advice. |

Heat the flywheel a torch till it smokes. Don’t go crazy but it’s got to be pretty hot so that it will expand ever so slightly. Wack the puller bolt. It will send vibrations down the crank shaft and loosen the flywheel. The “nut” is the nut that holds the flywheel on the end of the crank shaft. Leave it on just so that it is flush with the end of the shaft. It will help to center the puller and possibly avoid damaging the end of the crank shaft. Here s a picture of my puller. Same as yours but has been used many times! It’s been though a few battles! I’ll also add a video of removing a flywheel the quick and dirt way. It’s much safer with a puller but will give you an idea of how and where to heat it.   youtu.be/uAY1H-zWMI8great! thanks for the images and tips, it is a big help!
i'd say so, that puller has seen quite a few battles it appears. lol
thanks for the YT vid link. i'll check it out.

finally got the flywheel off. many thanks to all especially xl130 for the images and vid. gotta have a LH 5/16 nut that's for sure. found some on Amazon if anyone interested...
--------------------------------------------------------------------------------------------------------- www.amazon.com/dp/B00L1L7GS6?psc=1&ref=ppx_yo2_dt_b_product_details Hard-to-Find Fastener 014973268718 Fine Left Hand Hex Nuts, 5/16-24, Piece-8 Brand: Hard-to-Find Fastener --------------------------------------------------------------------------------------------------------- obviously didn't need 8 of them but they delivered the next day and it got the task done. thanks to okie too as it did take me a few days of heat/cool and a day or two of saying the heck with it. put a LH nut on the crankshaft, put the puller back on with new bolts (first batch bent) getting em lined up and tighten it down. then put the propane on the flywheel again, tighten some more, etc and then tapped the big nut with a hammer and off it popped. appreciate all the help! |
