Engine

Post by 77 Ford » Mon Apr 10, 2017 12:17 pm

I was doing my annual maintenance on my 450c loader and it got me to thinking.

I think I need to put a bottom end in my motor, it has great oil pressure cold but struggles warm.

My injector pump needs rebuilt.

Its addicted to either to start

Its got a broken exhaust manifold

Im wondering if I would be better off to find a whole new engine for it. I know the C could have a turbo or non like mine. How much work would it be to convert it to a turbo?

Engine Replacement

Look for a non turbo 4239. Newer model and starts better. This should be an exact replacement for your non turbo 4219.

I was in a similar situation. I choose to do an in-frame overhaul. I have concerns about used parts/engines. It will cost more for an in-frame but at least you know exactly what you got.

I have a 450C that is going to need attention due to low oil pressure most likely
an in frame for me rings bearings liner seals and necessary caskets keeps price down.did a 350 over winter that way came out very good.

Thanks for the ideas and comments. Im still looking it all over and was thinking about my oil pressure issue. I know that can typically be camshaft bearings too, but I do not see any mention of them in the 4219. Does it not have camshaft bearings? I know there are some older tractors made that way it just rides insides the block journals.

Low oil pressure can be associated to balancer bushings which cannot be addressed with in frame rebuild. You will need to pull engine for access.

Also verify that the oil pressure gauge is working properly. My little dozer would show about 7 psi hot/idle with factory gauge. I put a mechanical gauge on it, and now shows 34 psi hot idle.

yeah check pressure with a known gauge, don't trust dash for accurate reading
also do a compression test to see what you have as well.
she might not be that bad, she might be ready for overhaul.
if you find low pressure or low compression at that point I would pull the oil pan to see how the crank journals look and measure the crank to see if you could do an in frame and re sleeve...any crank work a full teardown would be needed.
if you have a ton of hours, oil leaks etc you are better just pulling the motor and just replacing all gaskets etc.

Thanks for all the posts, I think I'll try and run down a gauge. I doubt that's it it shows 60psi when cold but might as well rule out the easy stuff first.

learn as much as you can about it's condition, then plan your attack from there.
if you do have low oil pressure, most likely the crank will be in need of turning to clean it up.....you may be able to find a used engine but you have no idea how much wear and what condition it is in
