460 hydraulic pump

I have a 460 gas that the hydraulic pump is about wore out. I am using it now but am thinking about putting in a new pump this weekend since it is raining. I have a book but would like to know from someone who's been in there if it is something I can do in a day or if I should wait until I have more time? You just can't compare the voice of experience to a book.
 
No issue really.
Put the !3 cylinder on compression (thumb in plug hole to feel pressure start, then rotating until the first timing mark lines up with the pointer.
Then photo the position of the rotor in the distributor (or Mag). Remove said mag/distributor, and lay on a clean cloth out of the way. Photo the drive coupler to assure timing correct.
Get a couple of rubber stoppers to plug up the hydraulic lines when removed. Remove the lines, then remove the pump. Reinstall the pump to assure correct timing. Reinstall the hydraulic lines (with new Orings), reinstall the distributor, and make sure it points in the same exact direction. Static time it and drive away. JimN
 
Ain't no big dael when changing one out. Drain the oil out of the transmission only and remove the p/s line and the main hyd. line unbolt the plate use a siff bladed putty knife to tap in under one corner and remove , unbolt the pump replace all O/rings and gskts make sure that ya have the nut on the pump shaft tight and put it back together. refill and change the hyd filter .
 
For us dummies, my 2606 uses the same IT manual as the 460 and the pumps for both appear to be the same. Just wondering what the removal of the distributor has to do with this?

I may pull my pump this weekend also except that mine is outside and we may get snow tonight and I also don't have any o-rings or gaskets lined up. Case-ih said today they can't get the thick gasket now, only the thin one and they also don't carry any thompson pumps anymore.

Guess I'm wondering what to expect too. Do we need to drain the oil or will it just drop about the same amount as when you change the filter.
 
Thanks vet, I got up in the middle of my post to watch the world series for a little bit and didn't see yours till after I posted.

I did read something about measuring your gasket so you can get the same size to get the gear spacing right. I'm not sure how much that matters. I hope to save the old one.
 
When ya remove the plate try real hard to save the gskt. and if ya have a set of caliper's then mic. it as the gskt sets the depth of the gear. Now i know that two thins are way tomuch . SO if ya have the thick gskt then you will need to find gskt. paper real close to what was on there and some real thin and amke up the gskt. his is not a hard job and all ya need is a pair of seizors a ballpein hammer ( the smaller the better) IF ya have never made a gskt before then your going to learn something new . Ya use the small end of the hammer to tap over the bolt holes and around the out side edges with the hammer head and it will cut the gskt out with out a problem Do this before ya mount the pumps to the plate then with a pen or pencil and a ruler ya mark it out the inside and cut it out..
 
You won't as it will be a bear just getting the pump plate off . Like i said ya will need a stiff blaede putty knife and a hammer and ya have to drive the putty knife into the corner of the plate and at times it is a fight and that plate also has two dowels and can come off hard.
 
I think I screwed up on my 504. I bought both the .019 and the .024 gaskets because I live 60 miles from a CNH dealer. I was on my 5th or 6th beer that day and I had to fight the plate. Rain was threatening and I wanted to get it back together. I think I used the .019 gasket. Would this be an issue?
