Just curious.

[Brian T]

A few weeks ago I removed 2 of the bolts that once held the engine splash pans to the frame, (long ago broken off) I did not take any notice of them until I was ready to toss them in the spare bolt box, they have holes in the bolts, did they use a cotter pin or where they wired?. ..... just curious.

They used a cotter pin...there should be, I think, 8, Three down each side of the frame (for 6) and one on each side of the front cross member (for 2) which has the punched out holes in the cross member itself.

I believe that the ones in the front cross member are for 28s only. Not sure if that means just early 28s or all 28s. I'll check the standards and the service bulletins.

The solid front mount was dropped in November 1928, so the engine pans should have changed and dropped the front bolt at that time. I can't get to the front crossmember on my 2-23-29 Tudor right now, but the solid mounts are factory cut for installation of the new spring engine mount, and I seem to remember seeing the holes for the front engine pans still being in the crossmember.

I just went and had a look and there are no holes on the crossmember, I believe the Frame is May 29, I just posted another Just Curious thread.

The holes in the early front cross member stopped around November of 28, the
change was due to the new front motor mount.

I thought this had been written about but may have just been a bad dream . The very early vehicles used cotters there. I don't recall just when (too lazy to look it up) but early/mid '28 the cotter was traded in for a standard lock washer. However the bolt worked just fine either way and it took some time before all the bolts were supplied without the cotter hole. The long time "28 guys" should know this!

My Feb-'29 Tudor has these same bolts, square nuts, and cotters (no bolts to the front cross member though.

Never had lock washers?

[Gary Karr]

The hex bolts with cotter holes (A-20553) did not use a lock washer. Lock washers were used with hex bolt (A-20534) which had no cotter holes.

The combination of square nuts and cotter pins just doesn't make common sense. But then I have been known to be wrong!

I know it does not make sence...but that is the way it was.

I know that's what the parts books indicate but someone didn't get that memo! As I said above, cars were produced with the cotter hole but using the lock washer. We've found multiple original examples. If I find my handwritten notes when doing some filing this week I'll let you know at least a couple of the cars.
