4430 camshaft

I had posted back a few months ago about finding my grandparents 4430 I was just updating that I finally got around to replacing the camshaft which I'm sure was original. I think I was on borrowed time because there were some teeth flaking off on the old one it wouldn't have run much longer. I replaced the oil pump gear also I'm sure it had been replaced at one time but the teeth were getting sharp again. I'm also going to roll all new bearings I and replace the rod bolts. The bearings were dated 1998 so I'm assuming it had been overhauled after my grandparents farm sale which was in 1995. It does start very good for a 4430 and so far doesn't seem to use any oil. I'm having the injection pump gone through currently and removing what was left of the mouse trap linkage and also having the injectors checked at the same time.

Don't be so sure it was original.
Those cams wore out before the engines
needed overhauled.
 
I do know the tractor had around 12,000 hours when it was sold in the winter of 1995 I really can't say how many total hours it has since but I would bet it has around 20,000 on it now buy who really knows for sure.
 
The early cams wore quicker than the newer ones did,, Deere had a program to check them at different intervals for wear and change them if needed,, The owner of the store I worked for changed all the older ones under warranty as a favor to the customers,,Deere wanted to cover them if they had too under warranty and let the customer pay after warranty time ran out..I still have one of the gauges that they used to check them,,well at least the needle part,, you would remove the tach drive cover and slip the needle over the the oil pump shaft and a scale bolted to the cove area,, wiggle the needle back and forth to check the back lash..Here are some pics of the tool..

That,s not necessarily true.IT depend a lot on usage tractor started every day in cold weather cold be very had on those gears summer only last an last. cold starts the oil pumps get the pull very hard gets the gears to Waring sooner then it should block heaters help a lot
 
It was a big enough problem that there was a recall early on for those
tractors to check the tooth wear.
I've replaced several cams on tractors that didn't need overhauling.
You are right though that the bigger the pump load the faster the wear.
 
Ooh yes cold start up is where one with worn thin teeth would let go,,I know of a couple back then where the owner would start the tractor an a cold morning and walk away to do some thing else as it warmed up...come back and it would be locked up...Weather has a lot to do with how we farm and how the equipment deals with it..
 
Where has that pointer been Tim?
I used mine on every one of those old tractors
that came in for whatever. And that was the
first thing I checked on tractors I bought.
Many were scary worn.
I don't do as much as I used to and there aren't
many of those tractors being used around here
anymore either.
 
I know that I am going off on a tangent but was there not a high lobed cam originally used in the late 40 series tractors and 20 series combines that pullers put in the 30 series 404's?
 

I had the cam replaced on mine when it was about 8 years old. Just guessing but probably about 4000 hours. You could have shaved with the gear.
