does the fan run all the time or turn on only when riding for a long time i dont know if mine is working
-
The fan should start when the engine reaches 103oC.
Not unusal that the fan is stucked, caused by to less use..........and high pressure washing equipment.

There is an easy way to jumper the wires in the junction box under the tank. That will tell you if your fan runs or not. I think those instructions are in the Lieberry area here. Do a search and see if you can find it. Or maybe someone will link if for you.

Hi guys,
I'm new to K1100 - my cooling fan is not working and is sticky.
The bike is pulled down - do I go straight out and get a new motor, or, is it possible to pull the motor down and clean it up.
Thanks

The most common problem with the fan motors is melted brush holders caused by seized or sticky axle/motor.
-
So since I don't think they even make rebuild kits for these crappy motors, your best bet is to buy a new fan motor from beemerboneyard.com or euromotoelectrics.com and swap the old with the new -- probably around $80. Search this forum for install details. Or go to the dealer and pay about $250 for a new fan assembly -- but while you're at the dealer don't drop the soap!

It would probably be cheaper to visit a Bosch dealer/workshop, if such a thing exist down under.
Fan motor: Bosch 0 130 007 027.

My K75 cooling fan was in the same condition when I got the bike year & a half ago. 'Sticky' was turning the fan by hand and the fan was spinning on a seized shaft.
It is 'possible' to remove the front cap from the fan motor, knock the armature from the cap, and polish the shaft. I lubed with 65% Moly. Don't know that I'd do it again.

Radiator fan replaced with Spal, possible fuel pump issue

This has worked great for me. Tons better than the OEM setup.

Well boys and girls, I tried my best to make a set of bushes (from and old set of starter motor bushes - with a Dremel)
I used a 2 part epoxy to remark the housings for the bushes.........
It all went back together well - but, I could not get continuity between the two terminals, I suspect I did not make a sure enough connection between the brushs and the terminals . . . .

Oh well - I tried,,,,,,
I got a 12V 3100RPM electric motor with very similar dimensions off the net today for $31 AU delivered from Hong Kong.
I will post the results.....
