1949 John Deere Time Lapse Muffler Replacement Attempt Video

kylew01 · Feb 11, 2012

Here's a time-lapse video I made today of my attempt to remove the hood on my 49 BW to get the muffler replaced. I ran out of time where I had a few snags and wasn't able to quite finish. Those bolts that hold the dash on are a pain--the square nuts were all turning freely. So I think I did more damage then good getting it off. This hood is cut, and that's probably why. The other problem is getting rods that run the shutter disconnected and out of the way. Hopefully I'll get it this next weekend. Seems like a horribly engineered job. I think had it been thought of properly we'd see a lot less cut hoods!

The most amazing part about this is the fact that they made this horrible failure in engineering from 1939 to 1952, through several "upgrades" of the A, B, and G. Of course, most mufflers weren't changed out in the first five or 10 years of a tractor's life, but some dim bulb should have clicked on in some engineer's head that "Hey, I don't think the farmer's gonna like having to TAKE THE STEERING WHEEL OFF TO CHANGE THE MUFFLER!!!"

I can't remember where I read it, but I read that Henry Dreyfuss fought tooth and nail to keep the muffler mounts hid under sheet metal into the 50, 60, and 70 as well. Supposedly, it wasn't "pretty" to have the mounting exposed for the muffler.

I can now see why my 49 A hood is cut. Runs the same. eamil is open------

Yes, it is very unfortunate. I have 3 tractors from that erra--a 39 A, 37 A, and the 49 B. Of the three, only the 47 is not cut. So far, the B is the most difficult to get off too.

In our experience with a pair of '52 Late Styled JD "B"s, there is NO reason the replace the muffler ( IF you are really WORKING them hard)..
Ours had had the Water Pumps installed, as they could not keep cool in the Mounted Pickers, etc..
JD replaced and ground the valves in ours steady for 2 Years..until the Original mufflers rusted off..
With straight pipes, they never burned another valve..
Needless to say, our hoods are not cut..!!!

That may be so... Mine started wobbling awfully bad last year. It had been replaced before (hence the cut), but I won't get to know the full extent of the damage until I have the hood all of the way off. If you watch this video of it working last year you'll be able to tell how bad it was getting.

On the G there is no reason to cut the hood, it is
all on top.

Nothing like a hot blonde working a Deere in the field.

That's interesting. I've never seen a G up close. I'll have to find some photos of the top of the hood where the muffler comes out and see how it is attached.

haha yeah she gets that a lot. For those just tuning in, we're referring to the youtube link I posted a few posts up.

What were we supposed to be looking at again in that video ?

Look closely at the muffler compared to the air stack. You'll see it's shaking like crazy.

I got the hood off tonight. It looks like whomever "fixed" it last time just used a welder and put a spot weld in each of the bolt holes on the muffler. That's why it came loose. Had they fixed it right the first time, I'd have a tractor that does not have a cut hood and a hackjob on the radiator inlet pipe.
