ilford 500h multigrade head cooling fan question

[George Richards]

Here's a link to one version of the fan, there is one with ball bearings and another with a bronze bearing. I don't know which one is used. Available for about $80 from most electronic parts sellers such as Newark.com.

WS40 is not a good lubricant, it dries out and becomes sticky.

I believe the "WD" in WD40 stands for Water Dispersant, so albeit it has some lubricating qualities, it's not a long term solution.

Water Displacement... but close enough.

Thanks, Leigh.

Driving East on RT 80 at night between no-wheres. across the Iowa plains, 1979, in a driving North blizzard with my mate and daughter, my Subaru shuddered and stopped dead, and I coasted to the breakdown lane. My mate never understood why I carried a tool bag, and had no clue when I retrieved it, lifted the bonnet, and in the blast of snow I removed he distributor cap covered with snow and flooded the distributor with WD40. We were off and away in ten minutes to a motel. She never, ever, understood the alternative if I had not prepared. For that and similar reasons she is my EX.

Thanks Guys for the ideas..

yesterday my pc crashed...yaay..
but anyway..i took apart the 2nd head i have and dont use at the moment,i did a very brief wd-40.ing..and after found some kugellagerfett(alias bearinggrease)
and it did the job..it became more quiet,so the 2nd head needs a fan replacement.
will take the other apart next week,and if it has the same issue than i will order 2 fans..otherwise just 1
took some pictures when i took it apart,it was pretty dirty..will show it later if my girlfriend wakes up,its in her phone,but i dont know how to copy them to the pc..
anyway..
Thanks Folks!

and the solution:


from now on i will do this more often,thats for sure..now that i know that it can look like this after a while.
next week i take the other apart too,and see if i need 1 or 2 fan to order.
Thanks everyone!
have a great one!
