Group,

A chunk came off my fan belt and I'm trying to replace it. I'm having a lot of trouble getting the belt around the engine pulley.

The car has a 6 Volt Alternator and came with a belt # 42-6324. I do not know the brand.

The only way that I could remove the belt from the engine pulley was to put the part with the "chunk" removed around the engine pulley. That gave me enough clearance to remove the belt.

Is there a "skinny" belt that I should use ? The old one fit the pulleys nice and worked fine.

There seems to be little clearance under the engine pulley for a belt ?

Sounds like engine mount problem. Does the crank block line up with the crank nut allowing the use of the hand crank to spin the engine?

Bill Lee/Virginia · 03-31-2014, 03:13 PM

I purchased a belt that was 1 inch longer and it fits like a glove. I do not have the belt stock number since it was several years ago. Try it. Luck.

If the belt won't go around the crank pulley, jack the engine up slightly and it will slip right in. Just be sure to put a block of wood between the pan and your jack.

Maybe this is just assumed, but I think it would be a good idea to also slightly loosen the single bold holding the front motor mount in the crossmember.

The above comments sounds like what I have to do also to replace my huckster belt. You may want to put something under your front motor mount to get it to sit a little higher so if you break down on the road sometime, you could replace it a little easer. Just make sure your crank will fit in pulley.

marc hildebrant · 03-31-2014, 04:35 PM

Folks,

Thanks for the comments. Currently, the crank fits very well into the engine pulley.

If I raise the motor slightly, do I need to do anything with the front bolt setting ?

Marc

CarlG · 03-31-2014, 04:58 PM

There is usually enough spring action there to lift it up the 1/8 or so needed to clear the belt.

Duffy1 · 03-31-2014, 06:10 PM

Depending on how close it is to going around the pulley . Mine was close so I stretched the belt using my floor jack. If it is close to going on you might want to give this a try before doing any thing else.

Fred K-OR · 03-31-2014, 06:18 PM

Do you maybe have some old dirt or something on your front cross member under the pulley that you could clean off also and get more clearance?

Mitch//pa · 03-31-2014, 07:51 PM

if the front castellation

nut is drawn down to tight that can be the difference. the front motor mount is supposed to float on the springs..

Mitch,

How should the nut be set ?

i set it just enough to get the cotter pin in.

Purdy Swoft · 03-31-2014, 09:17 PM

I agree with Mitch!!! I only tighten the castellated nut enough to just get the cotter pin through the hole. If the nut is tightened more it will also cause vibration.

Bruce Adams · 03-31-2014, 09:24 PM

If its CLOSE, then make a garrot from a string with a couple of loops (Bowline knots) on each end, put it through the belt and pull it to length to go over the alternator's pulley.

marc hildebrant · 03-31-2014, 09:32 PM

With regard to lifting the motor with a floor jack/wood on the oil pan...

Can the pan support the motor without crumbling ?

Marc

Purdy Swoft · 03-31-2014, 09:41 PM

Yes, you won't have to jack it up that much. I would also loosen the rear motor mount bolts to the engine, This will take strain off the flywheel housing.

I strongly agree with this suggestion. You do not want to crack the flywheel housing.

1931 flamingo · 04-01-2014, 08:24 AM

You could also try starting the belt onto the crank pulley and then hand crank it to pull the belt on.

Interesting the front of the engine lines up but the belt wont fit is the space provided. Yea, you have to lift the engine by loosening things up as mentioned.

marc hildebrant · 04-01-2014, 02:36 PM

Bought a new B42 gates belt today. Napa couldn't match up the numbers of the one I had.

The new belt is the same length and width...not quite as thick since it's new and the old one was worn/frayed some.

Once the weather gets warmer, I'll push out the car and work on it.

I'll clean under the engine pulley area first as it was dirty. Then I'll try the install using the methods suggested and let you know.

I had another suggestion to use the engine crank to lift the engine some. I.E. put it in the engine pulley and push down and have the engine end lift up (see-saw).

When I have to get the fan belt off I remove the generator pulley and that makes it easy for me.

Purdy Swoft · 04-01-2014, 04:07 PM

I remove the generator pulley to install the belt too. Marc is running an alternator.

Marc, I've always used a Gates 749 belt (TR22434) is the new number. Every since I put the Alt on I've used this belt.

MrBruce · 02-20-2015, 03:54 PM

Here's what I've used for years

A very good suggestion , I'm sure this will force belt into pulls groove

Tom Wesenberg · 02-20-2015, 09:39 PM

Since the generator has the least belt contact, the belt should go over the crank and water pump first, then finish with the generator. As mentioned, the new aluminum fan isn't quite as wide as the stock steel hub, so the belt rides a little higher on the fan. A belt 1" long might be needed.

fiddlybits · 02-20-2015, 09:51 PM

Chuck Norris could theater the belt and it would install itself.

Bruce Adams · 02-20-2015, 10:35 PM

I wonder if you could HEAT the belt to encourage stretching?

Rubber actually shrinks when heated.
