I may be able to grab a 450 diesel that turns over but is missing the distributor. Is the distributor from the diesel the same as the gas version? For that matter does anyone know what distributors will fit the 450 Diesel? Can I fit an M distributor for example? Thanks for any help.

First of all a 450D didn't use a magneto. If you just need a distributor gas and diesel are the same. If you need the dist. drive housing only diesel will work.

There is a way to turn the advance weights around on the mag to make it work the opposite direction

Hi Ralph I dont know excatly what your saying but most of the trips are the same .Except for the different advance ones I think there was like 3 or 4 of them.The rear mount has the pin for the pawls to hit that is on the opisite side on a LH trip and the Cam on the rotor shaft in side has to be repositioned to fire diferently on a LH mag also . along with the rotor butten gear timing. I say it that way so people dont get confused on it having two rotors. JON

MagMan, I was saying you can flip the trip dogs end for end and half over to set them up for counterclockwise rotation. I don't remember what you have to do on the catch pawl on the mag.I was playing with the impulse pawls tonight,so I know the pawls will work.Thanks Ralph

Yes diesle magnetos turn the opisite of gas Mags They are LH trip I know that some of the IH diesles were set up with a switch in the manifold so when you switched from gas it would ground the Magneto and stop the spark.Someone was asking how to get rid of one just a week or two back. As far as the Mag goes on Ebay Its one of mine and is a very nice unit. I think by the looks of it you may be able to pick it up pretty cheap. IT HAS A 15 DEGREE SPARK RANGE IMPULSE.It is one of the older ones with a missing speed of 120 RPMs and the pawls do not have springs.They return with cintrifigul force. So maybe someone can tell you for sure how it will work they were used on the MDs if that helps. JON

Did a quick search on Ebay and found a diesel magneto that should fit it.Good luck, Ed

I believe the M and the 450 Ih were basically the same engine apart from larger bore sizes in the 450 engine. Maybe you'll get lucky and they'll interchange.

Good luck Pawel

if you have a distributer off of a m or h, or about any of them will fit. you just have to change the camshaft in the distributer to the diesel one for reverse rotation doc.

That's so weird. Why would it matter which way it rotates. Does the cam ramp up too slowly when going the other way? That's the only thing I could think of. Maybe it would make the timing erratic cause it's supposed to open the points quickly. I'm thinking I could get the cam at the IH/case dealer.

It's not so much the cam, as it the advance mechanism, it would advance the wrong way. Even with a mag. the impluse would do the same thing.

Well, I may be barking up entirely the wrong forest let alone the wrong tree here seeing as I've never even seen a 450, let alone one of the gas start diesels. I know on the smaller or purely gas tractors the distributor (not sure about the mag. but I assume it's similar the same) has an automatic spark advance. This works with a set of fly weights and if they and the rest of the internal components aren't set up for the correct direction of rotation then it would retard the spark not advance it. Hope this helps, SAm in NS

Richard, I don,t know if they are the same. I do know that a Diesel Distributor turns the opposite direction of a Gasoline Distributer, so if you ever have the wires off and when you start it and it misses switch 2and 4 wires.

I don't think a diesel would have any reason to need a distrbuter- maybe your calling something else with a different name the distributer. A distributer does exactly what the name implies, it distributes power from the magneto to the spark plugs, and diesels (unless it is a dual fuel IH) don't have spark plugs, diesel fuel is ignited by the heat of compression only. Do you mean the injector pump?

By the way the M engine, the 400 engine and the 450 engine were basically all the same except for different bore sizes. Oskar

oskar, all IHC Diesels from beginning up through the 450 had a third valve in the head and a gasoline chamber you start them on gasoline let them warm a couple of mins, depending on the outside temp then switched them. I under stsnd the corect name was Diesel Plus.

The 450D does have a distributor since it starts on gas then switches over to diesel

A 450 diesel starts on gasoline an switches over to diesel.

Richard, I don't know about a distributor, but I think the magnetos on the diesels turned backwards to the gas engines.
