Tie rod hitting alternator

cleddy · Apr 7, 2015

We got the 9N out to disk plowed ground and on the first slope-miss-matched ground right-Front wheel tipped up enough where the tie rod hit the alternator pulley and bent fins to cause a loud noises. From the picture does it look like alternator is too close to the tie rod? I'm pretty sure belt is new from YT tractor parts. After a while we got onto driving to avoid wrecking up things to much. It seemed to happen on right turns the most or when tie rod was right under pulley.
Is there some bumpers to limit the front axle from tipping up so far? All new parts on front axle.

If it contacts, it's obviously too close.

I think you can rotate the bottom bracket so it at about 8 o'clock or 1 o'clock . On the lower setting it can hit the tie rod and on the upper setting mine shoves the cooling fins into the hood on a steep angle .

You can adjust the front end wider and turn the tire around to gain more clearance

C Leddy,

You mentioned the belt.
Hope I'm not out in left field but if the pulley on your alternator is smaller than original generator pulleys and if the new belt part # is based on the original generator pulley and bracket, then the alternator would lean outward excessively.

Is it possible to put a slightly shorter belt on it; i.e., is there any room left between the block and the alt body?

The pulley looks small to me, that said I spread the front end out 1 hole on mine like Ken said, that took care of it. BTW someone brought this same thing up yesterday and I gave the same response it may have been on a different forum.

Sometimes a slightly shorter belt make a huge difference!!

Ive got a 2N up on blocks right now, ready for paint and i noticed that the tie rod on the right side will hit the generator at full axle tilt. (And i have a stock size belt, stock generator) ive put in a new axle pivot pin and the tread width is set at the narrowest position. Going to move both axle sections out 2 holes, should cure it and tire spacing will stay within the track of rear tires.

I work mine in the woods alot and ran into that in off-camber or stump climbing situations. I made an idler pulley that rides on a long bolt through the lower alt bracket mount and then built a limiter brace that is like an inverted U that goes over the LH of the front axle bolster to keep the alt from being "adjusted" when I'm working by too much articulation.

I have a 9n with alternator. Mine doesn't have a conversion kit. The previous owner bought an alternator and made his own brackets. I raised it higher and have not had a problem so far with tie rod hitting the alternator. Mine still uses the original belt. I can still read Ford and 9n on the belt.

A few things to look at.

1, is your kingpin and bolster worn?

2, does the salt hang much lower than the or I final Genny? ( looks like it does )

Can you reposition it?

Options:

Weld limit tabs to the axle.

Install an idler puller and get salt high and tight like a few of us have done. Keeps belt off distributor.

If kingpin is bad, fix

Cleddy,Get a i/4" or 1/2" piece of key stock what ever it takes to keep the axle,tie rod from hitting the alternator and weld each end to the top of the axle under the support stop on the right hand side.That will limit the axle travel so it won't contact the tierod.

cleddy · Apr 7, 2015

That is a lot of good ideas to look at. The tractor was converted when I got it so pulley,shorter belt,bracket and extending wheels wider are all good things to look at and welding some little stops are good options. It sort of made me sick to mess up the newly painted pulley-fan but glad no real distructive damage done like breaking the alternator off or bending it.cleddy

Looks like your wheels might be set in more than mine. Move the front axle out one bolt hole would help.

cleddy · Apr 8, 2015

I could not get how sitting the wheels out would help except with wider geometry and less severe angle. Then when I looked at it again and the alternater is within 3/8"-1/2" already of touching the manifold I now see that with a wider wheel pattern the tie rod will entirely be away from the alternater and miss it. I am a little used to larger tractors and must have taken a stupid pill but thanks and that make complete sense now.

Had that problem with my 9-N when I got it. had a Delco alternater would hit tierod in some situations. When I needed to replace alternater. I found a small one at salvage yard from a Honda or some foreign car made in Korea. wires same as Delco. Has worked fine for ten years ,no problem. When I converted a Freg TO-30 to 12 V I used a Delco alt with an idler pulley from mower deck witch raised the alt. Both are working fine.
