Go to lowes/ small auto parts store and ask for a M14X1.5 About 2 inches long. The front axle is a soft metal. It also does not thread in very well being tapered. Why go through all the trouble to remove the wheel/brake/caliper? The bolt is under $2. Well worth not taking it apart. Oh, as you may know. Use a torque wrench when puttung the new one on. You don't want to make a $50 mistake. Can't remember how much it was.

Use a 14mm 1.5 pitch 10mm or longer hex head bolt from the local hardware store. Make sure it has a flat face where the threads start. a 21mm or 22mm wrech fits the head and about 2 - turns will get the fan off Keith in Rocky River 2 - 81 GL500's 1 - 71 CL175 I ride solo cause the dog can't and the wife won't    Report

07-15-2008, 1:50 PM jazzmans Joined on 03-20-2008 Lost Wages Posts 47 Re: how do I remove the fan? so, once i screw the bolt into the fan face,  is it (standing in front of the bike looking at the fan)  clockwise or counterclockwise to remove the fan?   will I have to open and lock the cam as the shop manual states? thanks. no parts flew out onto me,  they all were trapped by the fan housing.  After I opened her up, the blades fell out. I still can't beleive i didn't shred the radiator. jaz life is what happens while you are making other plans. ::::::::; No-one sees motorcycles    Report

You can put the bike in gear,that will stop the camshaft moving.Don't be surprised if the threads in the,"Monkey Metal" in what's left of the fan don't let you use the bolt.In this case I made a couple of Wooden wedges out of some broom handle and hammered them either side of the fan to lever it off.This did not damage the Tach casing.

07-15-2008, 7:13 PM the cheese Joined on 11-23-2007 Baldwin,GA Posts 193 Re: how do I remove the fan? When installing the fan, how far do you press it on? I think I broke my first by forcing it on to far. Do you just put the fan on the end of the cam and start the bolt and stop at 18 ft.-lbs? Or do you force it on more (to make it go onto the cam) then losen the bolt and then set it to the right torque? I don't want to wrech another fan.

Put the fan on the cam shaft, tighten it to the 18 ft. lbs, and leave it like an old girl friend! Do NOT over tighten it! It's a wedge shape, and in theory, you could spread it out and split it into! If your going to do something, do it right, don't do it half as@*d. http://globalcxglvtwins.hostingdelivered.com/    Report

The recommended torque is between 14/18 ft lbs.I do mine to around 16 ft lbs.I smear some grease on the shaft for ease of release next time and a little thread lock on the bolt.This has served me well for 4 years.

07-28-2008, 2:24 AM jazzmans Joined on 03-20-2008 Lost Wages Posts 47 Re: how do I remove the fan? Hey Y'all! I've been successfull so far on me bike.  Installed new thermostat, radiator cap, overflow bottle (yes, you MUST drop the engine and push it forward) and fan.  My bike runs much cooler,  from what I can gather on a small test ride then it did.  right at 1/2 at surface road speeds,  just under 3/4 at interstate speeds. I do have some issue with the fan rubbing on the housing somewhere at high rpm however.  I installed a new fan from honda fwiw.  My tach doesn't work (never did) so I can't say what rpm, but it's up there.  not too far from where I normally shift, and it's a heinous noise, just like when a space fan is rubbing on its frame.  Any suggestions would be helpfull. Thanks for all the help and suggestions.  This place rocks! I think long term,  I'm going to look for a headlight and mounting bracket so I can do without the windjammer in the hot months. jaz life is what happens while you are making other plans. ::::::::; No-one sees motorcycles    Report

07-29-2008, 2:30 AM jazzmans Joined on 03-20-2008 Lost Wages Posts 47 Re: how do I remove the fan? Hey all. I pulled the windjammer fairing, crash bars, radiator, fan shroud off, and the shroud looked to be perfectly round.   I bent the radiator mounts so it sits a little further from the fan, and didn't put the fairing or fairing mounts back on. She's naked! anyway,  the horrid high speed(rpm) noise is gone, but I swear it slightly rubs somewhere, fuck-if-I know how to find it.  I rode 100 + miles this evening.   I love this bike. Now to get turn signals for the front, I'm preferential to turn signals. jaz life is what happens while you are making other plans. ::::::::; No-one sees motorcycles    Report

HTH :) I'm having the same exact problem about fan removal.  Tried putting it in gear, but that didnt stop the camshaft from moving.  The fan is atttached directly to the camshaft, but how?  Is it threaded or just kinda wedged on the end of the camshaft? Ive screwed a long bolt into the camshaft.  Now what?  I'm not sure I know what to turn which ways in order to remove the fan.

No threads what so ever. Screw ina m14 1.5 bolt about 2 inches long. Turn it clockwise in first gear. If that doesn't work have someone step on the rear brake to stop the wheel from turning.. If that still doesn't work. Make up some wedges out of wood at as small angle and tap them in behind the fan. When I removed my fan all it took was a half turn of the big bolt and it fell right off. 1978 Honda Cx500 Maggot 1979 Honda Cx500 Custom 1980 Honda Cx500 Deluxe Couch Project Bike CX500 Factory Service Manual Courtesy of Randall-in-Mpls    Report

If it still doesn't come off the next part of the solution would be to use a cutting wheel to remove the fan.  Cut the slot near the edge of the metal. The metal is pure crap so it shouldn't take to much. 1978 Honda Cx500 Maggot 1979 Honda Cx500 Custom 1980 Honda Cx500 Deluxe Couch Project Bike CX500 Factory Service Manual Courtesy of Randall-in-Mpls    Report
