Help with air cleaner hose ford 4500

[frankinri]

Working on getting a ford 4500 back to life and wondering if others out there that have one can answer a question for me about the hole I see in the air cleaner hose to the intake. Seems like it should not be there. What do you think? Image is here

New users aren't allowed to post pictures until they have around 10 or so posts. It keeps spammers from flooding the site with advertisement pictures. While you're working up to enough posts to allow you to post your pictures, is it a diesel or a gas engine? Later diesel tractors had an air filter sensor that sensed via the strength of the vavuum in the intake when the filter needed to be serviced. Perhaps a previous owner installed one of those ?

The 4500 never had a sensor stock. Some later models had a simple mechanical indicator that was installed into a hole in the intake that would move a piece inside a clear housing when the vacuum got too high and it would show red, which indicated the filter needed to be serviced. You had to open the hood and look at the sensor to see it. Lots of folks added third party sensors to older tractors once they became popular. I was just guessing that a previous owner added one at some point and then later it fell out and wasn't replaced.

Then later at some point Ford started using an electrical switch type of sensor that was hooked to an indicator light on the instrument panel.

If it's a nice round hole I would just find something to plug it or wrap it with some tape. If it's a jagged hole that doesn't look like it can be sealed easily then replace the hose. In any event you don't want the engine sucking dirt in through the hole.

Thank you

possibly put there so to give the engine a shot of ether.

Good point. Maybe a plug will be best.

Replace that hose. Plug as a plastic plug wont last long, Duct tape is temp fix. That hole lets in more air than goes thru filter along with plenty of dirt.

Replace the hose, there's a lot of dust and dirt comes off the fan in that area that can get sucked into the engine through that hole.
Who ever made that hole wasn't vert smart.

I've got a industrial model to rebuild because someone tried to duct tape a bad spot in that hose, sucked the engine full of dust and eat the rings up.

You're lucky. Lusted for a 3000 for years. Finally a '65 shows up going to work one morning, 5700 give or take hours, rough service....hole worn in metal
clutch pedal, nodules worn off brake pedals, you could tell tin had the dents banged out and some wanna-be painter exhausted a couple of rattle cans of
Ford blue at it, to give you and idea as to usage.

April in Texas....salesman had to use ether to get it to light off. Being a novice, and missing the fact that THE AIR CLEANER TO INTAKE MANIFOLD RUBBER
HOSE WASN'T THERE......I forked over $3950, another $500 on starter, 925 CCA sealed battery, and new cables, 00 at that, and finally met my maker.
Realized that it had to be that my compression wasn't adequate. I did an inframe, another $1000 machine work on the head and pistons, rings and other
necessities, and then another $750 for rubber all around and finally got something worth having. That was probably 30 years ago and just had the injector
pump go out...first problem in all that time, did put brake shoes on it. Got it fixed for less than $400. Turned out to be a good deal after all.
