Cooling trouble

[mondei]

Well I own a few Honda's, my current daily driver has a wee
situation with the cooling fan. Last night on a family outing there
was quite some sqeeling and then a little black smoke from under the
hood... agggh oh no!!! we it is not that bad, the bearing on the fan
itself appears to have siezed, the other 2 bearings are very free
running.
I wanted to replace the bearing on my 600 housing but I had real
trouble even trying to budge the fan off, So terefore one needs some
advice of the best way to approch this, I do have a spare fan and
all, but that does not solve the problem of fixing the broken one!
If anyone is wise enough about this to help me, it would be very much
appreciated, and I would wish that person a very merry xmas and happy
new year.
Well I give all those wishes to all the group anyway
Have a great one!!!
Kind Regards

Hi there Quentin;
You will need a press to remove the pin that travels through the pulley
and bearings and fan. A machine shop does all mine. My venture to do it
myself proved difficult and almost broke the bearing housing. The pin gets
rusty and causes all kinds of problems.

Most likely the machine shop is using a tool called a bearing
splitter but not as it was meant to be used. They would clamp it onto
the center of the pulley as there is no room under the pulley.
The way I do it is to drive the shaft out by striking it on the
shaft. Don't use too huge of a hammer as you can break the supports.
Since the bearings are shot, you will not harm them, but do not make
the mistake to push the shaft through the plastic fan side - you must
drive it thru the pulley side. The shaft is serrated. Once the fan
shaft is out, replace the bearings, knock the fan shaft back into the
bearings then support the bearing inner with a socket - finish
driving in shaft, flip fan assy over support fan shaft center then
press on fan, make sure pulley is flush with shaft. Yer done.
The exploded view in the parts book is best reference.

Thankyou Miles and Bill I will grab this advice and go for it in the morning. Does anyone have a nice exploded view of the assembly?
I think the so called exploded view in the Hynes book that I have is a sorry excuse for one, I need a magnifying glass, and I do not think that there is quite enough detail in the drawing :o)
Thanks gain for the help guys... Appreciated truly

This is from the Sedan Parts manual.  I hope it helps.  When I purchased new fans it came with the fan attached to the shaft (as shown in the parts manual).  The shop I use pushes the shaft through the pulley side leaving the fan attached.  They jigged the housing so the center shaft could be pressed out, then removed the bearings reversing the process to replace the bearings.  Replacing the pulley last.  But Miles suggestion may be better in the home work shop.

sheave (pulley) wearing out on the sides? I wore out about 4 or 5
over the years, they're like a razor blade now! Good ones are hard
to find!!I think I'll just pull the fan and housing off! (Can't do
that in CA,but in the South-Pole you can)! Tip of the month-Never
run belt to tight,and run a narrow belt! When replacing belt,my way
is to remove both pulleys by taking the whole assembly off,but first
loosen slack adjuster nut, then hook new belt in or behind the fan
housing to log-on to fan! Then,while holding belt on fan and crank
pulley,insert idler assembly pulley mount bolt thru hole in fan
housing! Tighten assembly nut and adjust belt to specs!

Don't waste yer time loosening the fan assy. It's easy to install a
new belt and takes only a few minutes. It's true though, the adjuster
pulley doesn't have to be extremely tight, that belt only runs the
fan.
I have electric fan on my car, works great, runs all the time, car
never overheats.

What sort of fan have you put in and how have you mounted it.. do you have any pictures of the assembly with electro' fan??

remove Idler assembly by removing one nut! And I tried many other
ways,But this works very nice,especially on a "hard to work on
coupes"!Riceburner006
