Fan oil
As previously mention I知 getting 40 coupe ready for long trip. Reading shop manual it says, remove screw, use tranny gear oil (1 oz) and then prior to putting screw back turn fan (placing cloth under) and only excess oil will come out. Return to top position and put screw back.
I知 not doubting the Bible (and maybe to difficult to explain) but curious how this is designed to work.

Re: Fan oil
Are you sure, believe that should be engine oil. I think you drain it because the fan assemble will throw it all over the place if it is full.
I just checked 4 different lubrication sources and they all specify engine oil. |

Thanks double checked. You again are correct.

Re: Fan oil
"One problem - a fan on a '40 doesn't get oiled."
Details, details! |

Kube is correct, as usual. '40 fans are glued directly to the crankshaft. It's the '42-'48 fans that do the weird oiling. DD |

Re: Fan oil
I'm not that familiar with 41s, but the 41 lube charts also list oil the fan on them. Any insight? Did they move the fan off of the crank in 41?

J.....I was pretty sure that '41s still had the fan on the crank. Nevertheless, VanPelt's site shows '42-onward for the weird-oiling fan hub. DD |

Re: Fan oil
Think it does take gear oil. I have a service bulletin somewhere that calls for 90wt and it was a change from engine oil.

Re: Fan oil
I use 30W non detergent oil in mine. When you take the hub apart and see how it's made it looks to me like 90W is too thick to lubricate properly. I have 12,000+ miles and no trouble.

Re: Fan oil
I do believe the Ford SB did make a change for those that had seeping problems as was mentioned. I don't know if they ever changed the standard procedure though. Seepy fans were a sign of wear of the internal metal on metal journal bearings or deterioration of the flange gasket joint. New parts are available for that type of fan. Ford used them into the 8BA era for some trucks & early 49 Mercury cars. The reservoir is filled to the bearing line and any over fill drains out when it's rotated with the fill hole down. They don't really hold a lot of oil.

Re: Fan oil
30-9. I would suggest that you remove the fan assembly and dismantle it to get rid of the old oil and clean it up. You have no way of draining the old oil without tearing it down. You will need two gaskets, that you can make yourself. When I opened up the fan hub from my 46, there was some gooey stuff in the housing. I cleaned, assembled and filled as per the service manual with HD30 motor oil. 600 miles so far and no problems.

Re: Fan oil
Anyone have a 1940 owners manual with a lubrication chart in it? I have a copy of what is ID'd as a 1940 Deluxe chart that list engine oil for the fan. So either the chart is miss-ID'd or Ford wasn't that careful in checking the changes from year to year on their charts. Not a big deal by any means, just seemed interesting.

You posted this one on the "greasing" thread a few days ago. Isn't this one a '40? It doesn't have a greasable fan hub on it. Ken |
