FE35 perkins diesel injector pump leak

I have a 1961 FE35 with a 3 cly Perkins diesel, the injector pump leaks, and seams to becoming from around the top of the unit. Is this something that a shad tree mach. can fix? In the process of restoring tractor and would like to fix this before I paint.

Is your pump a CAV? If it is a CAV, I have been there done that. The CAV is prone to leaking around the throttle shaft and the cut-off shaft. First you will need to get 2 or 3 cans of engine cleaner. Clean, clean, and clean again the whole area. After each spraying, hose off, let dry and do it again. Cleaner the better, if you drop a ball of grease/dirt into the top while the cover is off - big trouble, one piece of crud dropped into the bottom of the pump will cost you about $600-700. Now using a paper towel, start looking for your leak; it will show up real easy on the dry, clean paper towel.
1. MOST important thing is to have some paper and pencil BEFORE you take off the cover.
2. Remove shut-off linkage and throttle linkage.
3. Remove screws or nuts holding lid on.
4. DO NOT just lift up the top. Lift it just a little, very carefully so you can peek under it. A spring is attached from the lid to the bottom part of the pump. One end of spring is hooked on a wide post looking like a tombstone. The tombstone has several holes in it. Write down which hole the spring is hooked in before you remove it. The other end is through one of the holes in the flattened end of the control rod. Again write down the hole it is in before you remove it. This step is VERY IMPORTANT. If the spring is not reassembled to EXACTLY the same holes on both ends, the tractor will never run right again. The same pump can be used on different model tractors with the only difference being how the spring is hooked. My MF dealer mechanic can tell the proper holes by using the 3 numbers on the CAV. Now remove the spring, and lift off the lid.
5. Write down the model/year of tractor, and the model of the CAV pump and serial number. There are 3 different numbers on my CAV pump.
6. Take the cover with you and head to MF dealer and purchase a new gasket and four (4) tiny o-rings that fit around the throttle shaft and the shut-off shaft. Each shaft has 2 o-rings. If the o-rings are not leaking now, they soon will so replace all of them. Total cost of gasket and 4 o-rings is about $5 or $6.
7. You will need a little patience and two extra hands to get the spring attached on both ends and the new gasket fitted. I did this complete procedure on my MF 690 and now it has NO LEAKS.

If it has a CAV pump,it's a simple fix,did one last week.You'll need a gasket and 4 o rings available from Agco or New holland.Shut off the fuel. Disconnect throttle and shutoff rods, remove the 2 acorn nuts and lift up the cap enough to unhook the spring inside, remove the cap. Remove the shafts and replace the two orings on each shaft, replace the cover gasket. Put the cap back down enough to hook the spring and and engage the pin on the shut off shaft into shut off rail. Install the cap, tighten the nuts, hook up the rods and bleed the pump.

yes it is a CAV...
