Tie rod ends for '31 Buick Sr. 60 - What else might work?

Recommended Posts

The tie rod ends for my '31 Buick Sr. 60 are worn out. None of the usual parts places that I know about have these. Before I try to get them made, I was thinking there may be other makes that have something close that will work. I have seen a parts book page that refers to these as ES-15. The pic's below show a different number.

Some dimensions are:

Taper 1:8

Female thread is RH 1" 18 TPI for both ends

Length to center of stud 3-5/8"

small end taper diameter is 0.650"

Large end taper diameter is 0.750"

Thank you for the help,

Joel

Did you perhaps get off a line??  You seem to come under ES12 rather than ES`15

FWIW, a May 1941 McQuay-Norris catalog lists, under Buick ES12:

1930 Six, Series 50, 60

1931-32 Series 80, 90, 3280, 3290

1933 3380, 3390

ES15 is listed for:

31-32 860, 3260

1933 3360

An earlier catalog has specs:

ES12---type A (eccentric), Diam socket thread 11/8-18 NF, Dia of ball 11/8, High dia of taper .811, Low dia of taper .695, length of taper 15/16, thread size of stud 5/8-18..

ES15---Type A, 1-16 ANT, 1, .749, .648, 13/16, 9/16-18 Don't know what NF and ANT mean.

That spec list has numerous listings showing more than one make, but yours are just the Buicks shown; of course, a regular interchange manual might show more...

Thank you all for the helpful comments. I've tried to find an online TRW catalogue and so far, I've not found something that is searchable. I'll keep looking for it; I did find one for MOOG but nothing really close. I noticed that my 1" thread count of 18 TPI may be wrong. I will have to unscrew it some to reveal more threads and get a better count. The "1-16 ANT" leads me to believe that the rod has 16 TPI.

I did find Rare Parts, haven't contacted them but it looks like a very good possibility.

Thanks again for your help, if you have a link to the right TRW catalogue or .pdf please let me know.

A bit of good news late today. I sent the dimensions to Rare Patrs and they have a part number but none in stock. They'll check with their machine shop to see if they can make it. They sent a pic and specs that I will try to post but can't from my iPhone.

I always dread the $$$ involved in these sort of things but at least I won't have to get them chrome plated!

Thanks again and I'll follow up with hopefully the rest of the good news.

My apologies, I know it's bad form to hijack a thread, but at least I'm part way on topic.  Years ago I picked up these NOS tie rod ends at Hershey and have absolutely no idea what they fit - and I'd like to find an appropriate home for them.  I assume thery're Moog as they have an "M" logo but the only other markings that I can find are "2L" and "2R".  Anyone have any ideas on finding what application they are for?  Of course I can take some measurements.

Owen,

 

They may very well work for my application. Please take some measurements and we'll find out. 

 

First, the female thread is 1" fine thread and it should be right hand thread for both of them.  If this is what you have then let's go to the next critical measurement.

 

Second is the diameter of the small end of the taper.  It should be very close to 0.650".  Let's call this measurement D1.

 

Next, the diameter of the large end of the taper, it should be about 0.750".  Let's call this measurement D2.

 

Now, measure the approximate length of the taper, it will likely be very close to 13/16" or 0.81".  Let's call this L.

 

Calculate as follows:  Taper is equal to L divided by D2 - D1 and that should be very close to 8.

 

If this is what you have, we need to talk.

 

Thank you,

Joel

Ok, made some measurements and these are for a larger vehicle than yours. The bore threads are NF but hard to measure the diameter without knowing how much the OD is reduced by clamping and threads too far inside to gauge the tpi. Taper small end is 0.700, large end 0.810, length 0.955

Joel,

Worse comes to worse I have engineer drawings of the tie rod I can copy for you if you are going to have them made.

I needed a set a year or two ago but found a pair of decent used ones.

If I remember Rare parts or someone like them would build a set up, but when I checked a couple of years ago I think it was like $400 each!

I have posted below the information sent to me from Rare Parts.  It's the specifications for their part number that matches my measurements.  I've asked for a price but haven't heard back.  After what Chuck posted above, I'm not sure I want to hear it.

 

I've been to this spot before, it's the point where "Joel's crazy ideas" start happening. :wacko:

 

I'll give you the damage report when it comes,

Thanks again,

Joel

Here's a little more information on this. Rare Parts quoted $210 for each tie rod and they will need my old ones.

I need to close a couple loose ends but I'll likely go that route.

I did have an interesting thought on the ones that Owen has and mentioned above. A tapering bit is probably all that is needed to make them work on my car. Easier said than done I'm sure.

Thanks again for your help,

Joel
