Front heater fan.

Post by lars » Thu Apr 04, 2013 8:28 am

The front heater fan on my Bongo has started to whine recently, is it possible to re grease the bearing, or am I looking at a sealed unit which will have to be replaced at around £185?

Problems with the heater motor, bearings & resistor are extensively covered on the forum & the search facility will bring up lots of reading material.

There is also useful FAQ on the subject: http://www.igmaynard.co.uk/bongo/forum/ ... 43&t=28727

It is worth having a read of the heater resistor factsheet as this mentions bearing problems and the blocked drain hole which is usually thing that starts a chain of events & therefore is the first thing to address: http://www.igmaynard.co.uk/bongo/member ... sistor.pdf

hi lars

have a go yourself before shelling out for a new motor - fan etc

i did mine 2 weeks ago - works a treat

im not mechanically minded - but im an engineer - so yeh - daft as a plank lol

you only need
10 mm and maybe 12 mm spanners ( sockets will be better )
normail screwdriver
possi or cross screwdriver

wd 40
what ever grease you may have

i ended up dobbin a bit of vasaline in there lol

i followed the fact sheet a little ( changing bushes in fan motor )

i didnt need it until i couldnt get the main cowling off that attaches to the bulk head
all screws and nuts out- and off - yet it still wouldnt come away - read the fact sheet

ahaaa from the glove box - undo the electrical connection for the recirculation vent :oops:

done - and straight out

fan out - take bottom off motor -- 2 screws - be carefull

little bronze bearing in the bottom- soak the cap and bearing with wd and leave to soak for 30 mins - go to the motor electrical bit

make sure the brushes have meat of them - i used tissue etc and cleaned all muck dust and crap to what i could remove and see....

wiped the cap clean - and inside the bearing - little dap of grease inside the cap

put back together - carefully lol

i must admit - my curiosity got the better of me - so i plugged the motor fan back in to the electrics - started van - switched fan on ----- owww yeh - so smooth

when i get in the bongo now - i put the fan on just for the sake of it :lol: =D>

job well done

start to finish 1 hour and 3/4 - and i did take my time

hey - if all goes balls up - then buy a new fan

=D> =D> =D> big thanks to fact sheet guy and peeps that take the time out to do these things

thanks
andy
