We've got an International 444. Last fall, I installed a new injectin pump and all is now working fine.
During the install process, I found three bolts. I don't have any pictures, so I'll try to describe the process....
ON the side of the machine is the drive gear for the pump. The pump installs with the drive head facing the front. The gear housing allows BOTH sides of it (covers) to be removed.
I had to take them both off for various reasons...while the front was off (the side OPPOSITE where the pump actually attaches) I found three bolts. They were let's say, all 1/2" bolts by maybe 1" long. They were LOOSE in the bottom of this housing where they either fell off the front of the gear or maybe were slung up here by the timing chaing. (??)
I pulled them out thinking they held the pump to the actual gear BUT as I recall, they did not fit through the gear (there were little holes machined in the gear) AND the pump drive head, also had NO threads on it to allow them to bolt in.
I removed them and replaced the cover.
I installed what I call the 'drive pin' into the gear and this pin is what meshes with the drive head of the pump. I then put the pump into place, aligning the drive pin with the drive head (now the pump is timed to the engine) and bolted the pump on.
The bolts on the pump are much like bolts on an alternator...you have a pivot bolt that allows the unit to swing a few degrees left/right... then the other bolts have a little arc in them so you can rotate the pump and tighten them down.
The pump SEEMS to attach ONLY via these three bolts to the exterior of the housing.
That's all setup... here's the deal...
My brother in law called today, all kinds of ants in his pants.... he is just swearing that there is NO WAY the drive gear can NOT be bolted to the front of the pump. Forget that there are no threads in the pumps head, forget that the bolts I found were not long enough to go through the gear and into the pump head, forget that this would now mean having to disassemble BOTH sides of this attachment to remove/install a new pump... forget that the pump is already attached to the mounting plate with three bolts.
I've looked on their website www.caseih.com and they don't have enough detail to show if the injection pump is supposed to be bolted to the gear or not.
Everything I could see, indicated it was this 'pin' that exclusively powered the pump but my brother in law doesn't think I'm right.
Although the tractor works 100% fine now, he's nervous that this pin is going to shear, find its way into the engine and trash the entire tractor (which would probably be a GOOD thing!! )
So, with that story...
I'm asking if anyone knows specifically if a IH 444 injection pump BOLTS to the drive gear, or is it reasonable that it will simply be held next to the drive gear with the drive pin doing all the work?
Does anyone know factually of a pump that does NOT bolt to a drive gear that isn't an International??
I finally invited him over this weekend....said I'd take the entire thing apart again if he wanted, this way he could see for himself how the parts went and the issue of no threads to screw a bolt into.
Thoughts??
