Hello Folks,
Michael Ehrlich here. I'm the proud new owner of "Geneva", the Geneva Blue Cord 812 Beverly Supercharged formerly owned by Jack Richards. The car is sitting in my garage now in Clarksville MD, and I was about to take her out for my first drive. Oil, check. Coolant, check. Fan belt - big chunk missing on the backside! Seems like the smart thing to do is to replace the fan belt before I take my inaugural drive. So I looked at the tensioning mechanism (turn and slide mechanism) and loosened the two nuts to relieve the tension. That work fine. Then I looked at the problem again, and it seems like I need to remove the distributor completely to have enough clearance to get the belt out of the car. Am I missing something? Perhaps loosening or removing the two bolts that hold the water pump/fan mount to the transmission case? Even doing that it just doesn't look the whole assembly will move much. Anyone have some expert advice? Also, if anyone has a part number that would be great. Service manual says it is a H10334, and cross-referencing that shows a cogged belt, which mine isn't.

Thanks for any help you can provide.

-Michael

Congratulations are purchasing a great car. Jack had no issues driving this car from Arizona to Missouri when he purchased it. I'm not able to tell you how to remove the belt but am sure going to be watching this. Hopefully you do not have to roll the belt over the pulleys.

Hi Michael,

Congratulations on getting Geneva!

Changing the water pump belt is a major job. If I can think straight I'll lay out the steps.
1. Drain water
2. Remove horns
3.Remove distributor
4. Pull the upper radiator tubes
5. If you have internal exhaust I like to pull the fence to give me some room
6. Disconnect the radiator support and lean the radiator forward - sometimes it's easier to pull the radiator - it makes pulling the water pump easier, you don't have to remove the fan then.
7. Remove the fan
8. Remove the water pump
9. Remove the lower bolts on the water inlets - if you don't do this you have to bend the pulley to get the belt off
10. You can now remove the old belt.
Reverse the steps to install the new belt.

Additional comments
at some point you will have to remove the flywheel cover plate on the bottom to retrieve a bolt you dropped down in the bell housing.

If you have questions let me know.

Thanks for the posting Jim.Sounds like an engineering nightmare changing the belt. I'm guessing once its done you probably never have to do it again... Unless you have a "driver"...

Jim,

Thanks so much. After looking at a bit more today I decided it was NOT going to be a straightforward and quick job. Even releasing as much tension as possible and removing the distributor I still couldn't get the old belt off. I had pretty much decided that I needed to remove the water pump to do it, and now you've confirmed that! It's really only a few hours job - just hoping that it was only a few minutes job.

So, given that I'll have the cooling system apart to replace the belt, are there any other part I should check or replace? And any idea what the fan belt length/cross-section is? Or a modern day equivalent part number?

Thanks for all the help. Maybe I'll make a video to document the process.

Hi Michael,
The modern number for NAPA is 26341. Plan on about 6 hours to change the belt since you haven't done one, maybe more in this heat. I have it down to about 2 hours since I recently had a water pump out about 5 times on a Cord (that's another long story)
While the pump is out you may want to pull the pulley on the pump and take it apart and clean it up so you can adjust the tension easily when you put it back together. You really don't need much in the way of tension, just a little snug. Don't over tension it. The number I gave you is for a cog belt, it grips well. Excess tension will only wipe out the bearings in the water pump.

Also check your fan blades while it's apart and make sure there are not cracks in them. As long as the water pump is good, leave well enough alone. You can try to wiggle the ends of the shaft to make sure the bearing are good. Check hoses, you may want to replace them while you are in there. Again these are all standard items you should be doing as you work on this, I'm just mentioning it for those who don't think about it.

One other thing - have a universal joint and a long extension for your 3/8 sockets. It's about the only way to get the water pump off.

Good Luck!
