Hood is misaligned with top of dogleg

Postby lyle11 » Sun Apr 05, 2015 9:40 pm

This is my first post. I have found this site to be a extremely helpful over the years and it has helped me resolve every Cub problem I have encountered up to this point so I have never had a need to post a question. I really appreciate the help over the years. I fixed up a 1948 FCub a few years ago and bought a Cub Lowboy, year unknown, but red with a round hood, last fall. When I bought the Lowboy the doglegs were welded to the hood and the bottom of the doglegs did not line up with the threaded holes in the bolster. I removed the doglegs from the hood with a hacksaw and file and bought a set of aftermarket doglegs. I put the hood install on hold as I painted parts and replaced castings. I am now getting near the point when I will be ready to reinstall the hood. I loosely attached the radiator and set the hood in place. As you can see from the photo the hood doesn't line up with the dogleg when the bottom of the dogleg is fastened to the bolster.

The alignment problem is the same on both sides of the hood. As you can see, there is about a 1/4" gap at the front where the hood and dogleg should be in line. The hood is resting on top of the radiator and can go no lower. The only way I can make the hood parallel to the top of the dogleg is to elevate the rear of the hood at the tank support (dash) by about 1". My Tank Support is short eared style and is about 9 1/4" total height from the very bottom to the top of the flange that bolts to the tank. It has been welded at the corners but doesn't appear to have been altered.

Even after I elevate the rear of the hood/tank by the tank support, the front of the hood, although lined up is about 1/4" too high and can go no lower because it is contacting the radiator. The radiator has a little plate from a local shop and has been worked on at some point. The upper hose lines up perfectly. I replaced the front bolster and this one is weld free and very flat where the radiator sits.

I also noticed, although this is probably common, the gap where the hood is welded to the gas tank is narrow at the top of the tank, but larger on the sides. It does not appear to have every been repaired or altered. This results in what appears to be a slight upward slant from where the hood meets the tank to the front of the hood.

The logical thing to do would be to try the hood from my other Cub but it is located at my farm which is a not so convenient 700 miles away.

So. I see the following possiblilites:

- Radiator is too tall.
- Tank support is too short. Perhaps altered at some point.
- Hood is warped or distorted, perhaps from welding the doglegs to it. (It appears to be fine but have no other hood available to try or compare.)
- Some combination of the above.

Thanks for any ideas you might have.

My thought. Record the casting date from the tractor's major components. Try to determine the year of manufacture from the casting dates.

Once you have an approximate year/date of manufacturer you can determine the hood style.

It's quite possible that a previous owner changed the hood on the tractor.

Edit: My first name is Lyle. It was at one time quite common in central Iowa.

Appointment scheduled at local hospital for mammogram on sliver in finger. At the appointed time the nurse comes out and asks for Lyle. I get up and follow the nurse. Nurse says take off your pants. I ask why I'm taking off my pants when the mammogram is for my finger. Nurse again says take off your pants. I said I'm here to have the mammogram done on my finger.

Nurse asks if I am Lyle S------? I say no. So we go back to the waiting room. This time the nurse asks for Lyle S------ by first and last name.
I have an excuse. CRS.

What Eugene says makes sense. From what I can see of your hood it does appear to be a newer style of the round hood. The 47-49 hood has 3 embossed "lines" that run front to back.

If it turns out your hood is the right style though, obviously something else is going on.

While I don't have a definitive answer I don't think there should be a "slight slant", it should be straight across. To further compound your problem the hood isn't supposed to sit on the radiator. Usually there are small brackets that bolt to the radiator supports at the top and the hood bolts to those.

I'll measure my 49 to see if it's any different.

The radiator for later the model cub is a different (taller) height from what I have read on the forum. Maybe the one on your loboy has been changed at some point. I have a '57 LoBoy with the round red hood with the flat sides for the emblem mounting and the hood/doglegs fit good. I can measure something if you need to compare. PM or post msg and I'll try to help. Stan

I'm with Stan on this. You mention the radiator has a tag from a local shop. Quite possible the top of the radiator has been replaced with something taller or the entire radiator was replaced.

you said you replaced the doglegs with new aftermarket ones, if they are like aftermarket auto parts a lot of times they don't fit correctly. try borrowing a set of originals and give those a try.

Re: Hood is misaligned with top of dogleg

Thanks for the replies. It may very well be the radiator but I noticed TM only sells one. I am gonna take some pictures and measurements and post them. Here is some more info:

- Casting dates are mixed. Transmission and Hydraulic unit manufactured in 1955. Torque Tube 1948 or 1970. Engine is 1969. I replaced the bolster, both finals, and I did not note the old casting dates. Best guess is it is a 55. PO had no record of the SN.

- The air cleaner pipe only protrudes from the hood approximately 3/8" to 1/2" so the hood is sitting too high. It is a short style air cleaner and a PO actually spread the pipe and crammed an "inside the pipe" cap on it because there was no room to fit the proper cap on.

- I was not aware that there are differences in the fit of the hoods other than the bars on the side and the routing of the exhaust pipe. I am familiar with the 3 bar style on my 48 Cub. This is a flat sided hood with the "International Cub" emblem on the side. The hood brackets that fasten to the radiator sides have been moved to a location back and higher on the hood than the proper location. They are not restricting the hood now but will have to be moved to the right location if I stay with this hood. In fact, on one side there are 2 hood supports, the original lines up with forwardmost holes in the radiator side support and the other lines up roughly with the rear hole on the side support. So, a PO had them moved to try to match up with the side support.

I am going to remove the radiator and see if things line up with the radiator out of the way. It is empty and loosely attached until I resolve the issues with the fit of the hood.

Eugene, I was born in 1957 and grew up in Wisconsin. My mother originally spelled my name "Lisle". Man I hated that. Most times when a new teacher saw it when taking roll call they hestitated and said "Leslie?". It really isn't that hard. Just "isle" with an L in front. I finally had the spelling changed when I was 22 to Lyle and got that changed at the local Social Security office where I lived in Oklahoma, but I still got SS statements that listed me as Lisle. Oddly enough, I worked with another guy named Lyle who was a tractor nut and actually left the job to work for a tractor museum in California. He went by the name of Mac rather than Lyle. I like my name. I just disliked the non conventional spelling.

Here are a couple photos of the radiator with a ruler. Roughly 17 1/2" tall and about 16" to the center of the pipe. Can someone tell me of this appears to be out of spec?

Thanks

That is exactly what I just measured on one I have.
There are two ways to get enough Cubs. One is to continue to accumulate more and more. The other is to desire less.

Thanks Barnyard. So, it appears that my radiator is the correct height. It is in good shape with no leaks and on the one hand I did not want to replace it, but there is no way this hood will work with this radiator with doglegs attached properly. I see why the PO did what he did. If I can find a hood that works I will get one, but other than the relocation of hood support brackets and welding the doglegs I can't see a flaw with this hood that would throw it off like this. I am attaching a few photos in case something stands out to someone.

BTW, unrelated to my issue but since I was taking pictures I found another use for Cub wheel weights while a replaced my fuel pump.

Second picture shows 2 hood support brackets,on the hood on one side. Obviously, some weird PO repair.

Looks like PO swapped the radiator support brackets left to right, resulting in the threaded bolt hole for the tank to be in the wrong spot to fit the bracket on the tank. Looks like his fix was just to add a second bracket!!

Hood looks mangled, would not expect it to align properly. May have been caused by stupidity.
