Colt Case Ingersoll Garden Tractors

Seems strange but I have been working on my 1985 448, fitting my snowcaster, trying to get my new-to-me EZ clutch working as I want but during the process I noticed that the actuation arm (at least that's what i think caused this) has bent the B48M RH (from seat) rear engine tin back. I guess in my endeavors I could bend it back but what have others experienced here? How do I stop this happening again? should I be bending this back into place or just replacing? I guess the word is HELP!

Can you get a picture of what your seeing, I'll take a look at my 448.

Thanks Tim. I will get a picture in the morning and post

Pics of the bent rear RH baffle.
Couple of things to note here are that I am convinced that before the Snow Blower was fitted there was no damage and the damage occurred as the blower was raised off the ground by the hydraulics and looking closer it seems to be the arm holding the chute handle I guess the question - did I miss somethink and well do I just bend it back, buy new, what?

Your snowcaster or at least the lift arm is an older model that was supplied with Kohler engine powered tractors. When used with Onan engines the interference that you mention occurs. We cut off the crank support and reweld it to the pipe 6-8" further ahead to eliminate the problem.

Bob, my thanks ! From what you have said it makes perfect sense. Now I just need a "friend" to re weld the part for me. BTW the caster is a J model and has been used on my 1977 446 with a B&S 18hp till last year.

So I found three different part numbers for the damaged part! The negine in question is an ONAN B48M fitted to a 1985 (S/N varified but could be 1986 model). The part numbers I have are:
C20362
C24951
C28034

I err towards the last number but could be persuaded otherwise.
Checked online but none are available so I guess I'm into reworking what I have .. any help on how I should do that?

Thanks Bob, when you said "ahead" do you mean closer to the handle or closer to the caster?

Closer to the caster so that it doesn't travel back far enough to contact the shield.

Bob, Thank you!

If we don't talk before Christmas please have a great one with family and friends..

From comments back from members I think I need to take a two stage approach here. The first I need to rework the lift arm to move the rotator arm cross brace (at least thats what I am calling it) more towards the caster to give more clearance to the engine. The rotator arm though is very fragile due to age and use I guess we are talking here of a 1977'ish caster.
The engine tin also needs a lot of work to bring back to somewhat normal. For me I would prefer to replace but I checked on line and there are none available rirght now so it is what it is.. The weather here in WNY is in the early 20.s so today is off limits but check back... I need to fix this...

So, just for information. I have two snow casters a J series that came originally with my 1977 446 and a later L series that came with a 1985 448. Obviously, like most buyers I have no clue of the original origin...were they part of the original purchase, etc. I just assumed that they were but how do you really know the true story. So I checked the lift arms for both snowblowers and they are the same! That really surprised me. So it would appear that either model would have caused the same damage to my engine tin! For me I will deal with the issue at hand here, indeed I have just won a bid for a replacement tin on ebay(Case Ingersoll 446 Tractor Onan Engine RH Rear Heat Shield Air Deflector C28034). Trust me though I will be looking into how to repair the tin I have but also what others should do to not make them a victim of this too. Just know I have a very well stocked machine shop and will fix this!
