Good days folks, have a few questions. I've been running equipment for 40+ years and have a year and a half to retire. 3 years ago I bought a 450C. I've put about 1000 hrs on it and it has been a champ. I've made quite a bit of beer $ with it clearing lots, fire mitigation, roads, and ponds.
The only issue was the exhaust. The guy who used to own loosened the clamp on the exhaust and the chrome exhaust just wiggled around a bit. He said he ran it like that forever and had no problems. A JD tech looked at it and said it was fine.
So the other day I was finishing a pond and clearing brush and timber to build trails to the pond and for some reason the hood slipped off the radiator housing and the right side almost hit the fan. I cooled down and shut it down. I got the hood up where it's supposed to be and put a tarp strap in the exhaust pipe hole and attached the other end to the guard on the front of radiator.
That worked for about an hour then the exhaust pipe tipped all the way over to the left. After cooling off I remove the hood with pipe still in it. This guy had put a 2 1/4 to 3 1/4/ adapter on the exhaust. I cut the pipe just below the adapter and got everything apart. So the question is, should I try to just find a piece of straight pipe to put over that stub? The hole for the air cleaner is butted up tight toward the seat so it can't come forward at all to where it would fit snugly on the radiator side? Any suggestions would be great as I'm on the clock with this job.
Hood issues
Re: Hood issues
Welcome to the Boards.
Do you have the manuals for your 450C? If you don't know about this, you can use the online parts catalog for your 450C at jdparts.com. Here is a link to the online parts catalog if you don't have it. If you don't have the Operator's Manual (OMT71338 for a dozer) and Technical Manual (TM1102), post back for suggestions of where to get them. (I am guessing you have a crawler dozer; I don't see that you have told which it is.)
450C parts catalog PC1420
I mention the parts catalog because it shows you the different exhaust arrangements. You say your crawler has a turbo and straight exhaust stack. Looking at this page, https://partscatalog.deere.com/jdrc/sid ... Id/2641754, in Section 15 of the parts catalog it shows the exhaust pipe (item key 2) clamped to the manifold. JD used a flange on the manifold, gasket on the manifold then the short exhaust pipe, with a matching flange slips on the manifold stub and a split clamp (not a regular muffler clamp) captures the two flanges and locks them together. Per the note for the extension pipe (item key #1) "DOES NOT FASTEN DIRECTLY TO EXHAUST PIPE- FASTENS TO EXTENSION ON HOOD". If the previous owner hooked them together, that is wrong.
Looking in Section 55, the hood and grille page https://partscatalog.deere.com/jdrc/sid ... Id/2388555, it shows the extension for the exhaust made as part of the hood (item key #3). Right below the hood it shows item key 32, Latch. There should be one of those latches at each corner of the hood and a rubber isolator strip under both ends of the hood.
The hood exhaust stack should float around the exhaust pipe. The latches allow some movement of the hood to center up. You might have to loosen the radiator housing (nose) bolts to square it up. It all the bolts can be tight, but the nose might not have been fully back in place when they were last tightened.
To post pictures you have use a hosting site, like Post Image, Imgur, etc. This site has a dedicated picture server you can use as the hosting site. Here is a link to it. http://jdcrawlers.lcent.com:8000/johnde ... .php?cat=1 To set up your own gallery and albums you need to log in. You will need to email Lavoy and set up a user account for that server. There is some info about using the dedicated picture server on the MessageBoard Q&A and Announcements you can read when signed in here. It should be about the 8th thread down on that Board.

Re: Hood issues
Hey thanks for the info. I don't have the manuals for this tractor. It is a dozer by the way. I'll check these links for manuals and parts. I actually get depressed when I walk into my John Deere dealer and start asking for parts for my dozer, my tractor, or my 316 lawnmower. We have the 3 stooges behind the counter that look at you like you're speaking a foreign language when you ask for dozer, tractor, or lawnmower. So any info I can get is helpful. I'll post some pics/videos of this little machine working its heart out. The job I'm doing right now is for a production company way up in the northern Colorado Rockies. Thanks again.
Re: Hood issues
You can download the Operator's Manual for free at the JD Construction and Forestry Bookstore, as well as see the other manuals available for your machine and their prices. Click on this link to go to the Bookstore.
John Deere Construction and Forestry Bookstore
Type 450C in the "Model" search box then click the search icon at the right of the "Search Term" box.
When the page of manuals opens click the Crawlers box in the Product Line section in the left hand column. That will remover the skidders and some other machines.
The OMT71338 is the crawler dozer operator's manual. (OMT71337 is for the crawler loaders.)
Click the yellow download box and it will download a pdf cop to your computer, or device, which you can save to have for review or printing.
TM1102 is the Technical Manual for the 450C, available for purchase from the bookstore. You can see the JD prices there.
The _ suffix after the base publication number of the manuals is the current printing, it might have some changes not in an used OEM manual or reprint. I expect only minor changes for machines the age of a 450C. Using the online parts catalog generally insures you have the latest part number changes.
Lavoy may have access to the 450c manuals in his store, if you contact him. You can use the John Deere publication numbers to be sure you are looking at the right manuals if you search eBay or other places for good used OEM manuals or reprints.
The old hands that knew the parts business are getting fewer rapidly. I look up my own parts most of the time now, and have even had to help the new guys at the dealership look up parts in the store. It has been that the Lawn and garden and Ag tractor dealers (green equipment) could not access parts for the construction and forestry ("yellow" equipment) unless the part was used on the ag or turf equipment, as well as the construction side. Some of that may be changing where JD is getting mega-dealers set up. United Ag and Turf Northeast is buying up all the ag and turf dealers in New England and New York it seems. And they have started the same with the construction and forestry dealers. The two sides are talking some now, at least in the United branches, as I needed a piece of hydraulic hose the other day and the ag dealer had it transferred in for one of their construction dealers. Maybe that has already happened in your area.

Re: Hood issues
Based on your situation, it sounds like you're dealing with a bit of a makeshift setup that’s not quite ideal, especially since you're working against the clock. If I were in your shoes, I’d consider going with a straight piece of pipe to slip over the existing stub, but make sure to measure carefully to get the right fit. You might need to fabricate a custom bracket or clamp to secure it better, given the tight clearance around the air cleaner and the radiator. Another option could be to check with a muffler or exhaust shop that might be able to bend a pipe to fit your specific setup. The key is ensuring that whatever solution you go with doesn't restrict airflow or cause more problems down the road. Since you're still actively using the 450C, getting it done right the first time will save you headaches later.
