I am a new member and this is my first post
We bought lot 97 of Dorrington classic tractor auction in Geelong, Melbourne, Australia. I thought someone may be keen to view the catalogue. Lot 19 was my favourite.
It started and after a short run down to the hay shed the sump had 6 litres of diesel in it.
I have deduced the injector pump ( American Bosch) is leaking through the front gear cover into the sump.
To remove the pump for repairs is it a matter of unbolting the body from the engine or is there a procedure l must follow.
You advice will be greatly appreciated as a new member.

Quick question. In the disassembled injector pump fig 0684 from the manual there is a washer #47 behind # 46 the bronze filter.

My bolt assembly dosn't have one, is it a very thin steel washer
or a fibre washer and is it needed?

And should the lubricating bolt be bare metal to the pump body when screwed in or should there be a copper or fibre washer there also.

Sounds great. Hope it fixes it. Keep an eye on your oil and diesel. I only start with that O ring because it's the easiest. Cheers.

Well, well, well, a friend of a friend rang this afternoon with a lubricating bolt complete with filter. What luck and all for a carton of beer. Cheers.

Thanks Olliejunkie for all your postings and your offer, you did say that O ring first. Dieseltech and Scootergmc thanks for your efforts helping this Aussie novice.

There are other problems with the old 55 to work through but that's for another time.

A part like that in a small padded envelope will be about $15 by USPS to Australia. You want to keep the envelope no more than about 3/4" thick. If you box it, I think it will be more expensive, but I have never sent any of my stuff there by box.

If you have any pump shops near you I would see if they have a used one. I will see what the post office says. I'm sure it wont be cheap. Get back to me if you cant find one and we will figure it out.

That's a good question. I'm not a pump guy and only know what I have learned from others on here and playing with them. Perhaps Rich or John will be along soon. Bosch PSB pumps were used on other equipment and I have picked up a few used pumps here and there for parts. With the lack of availability of parts and close tolerances of these pumps I wouldn't recommend not running without it. These pumps are known to freeze up from sitting. 4 cylinder pumps seem harder to find than 6 cylinder. When you do get it back together I recommend keeping fresh fuel in it and running it monthly

Heres a picture of one with filter and o ring. The filter puts pressure against the o ring. I use a 3-5mm o ring to replace them. It seems to be working so far.

Thanks Olliejunkie that gives me a good impression of the missing screen/ filter. Does this little filter dose the fuel with a fine lubricant for the head unit?
If l cannot replace the filter I wonder with today"s fuel if one really needs the lubricant. I could just block it off.
I would rather have it though,

The small bronze filter is for the oil supply passage to the hydraulic head. Both filter and thick O ring MUST be in place to keep oil and fuel around the head assembly from mixing. Very late PSB pumps on military and some AC applications stopped using the filter, and used a special head bolt in place of the oil passage bolt. Both Oliver four and six cylinder pumps use the same oil bolt, filter, and thick O ring.

The o ring would hold the filter in place. I dont know if they're available or not. I do have a few extras I believe. They are a brass looking kind of material approx 1/2 inch round by 1/2 in long cylinder. It could be in there still or they fall off easy when removing.

Not having the filter can you tell me if it plays a role with the O ring. Could the fuel get through without it in place.

Are the screens available?

As I posted earlier that is the first o ring I replace. It is the easiest to get to and very cheap to replace. I have found that the o ring usually stays in the body and doesn't come out with the filter. I use a pick or bend a small wire with a bend in it and gently pull it out.

Hello John-

Take a look at this link. Are you talking about the filter screen (part #46)? The parts books are all online: https://na.apb.agcocorp.com/p/white/s19e4000/l/326?

Yes that's the part. #45 is the fat O ring, #46 is the missing filter.

Thanks for your postings.

I know a month has passed but l have made a small move forward.

I discovered the small lubricating filter at the back of the body is missing, the fat O ring is there but nothing to seal onto.

When l pressurised the diesel inlet the lubricating oil line at the bottom of the body was releasing the pressure.

I blocked the fat O ring off and the pressure held.

I think the diesel has been bleeding past the fat seal and down
to the sump through the bottom lubricating line.

Is this possible? If the engine isn't running could the diesel run back down. My sump may have filled up with the diesel while it wasn't running after all.

I would be most interested if you can follow my description what you make of this .

Regards John brooks

O. K> There are 5 O-rings. Only one seals fuel! The O-ring Oliver junkie is talking about keeps OIL from getting into the fuel tank! The one in the timing window is the only one that seals fuel. That is not your problem. It may leak but not as fast as you say. I will send you an e-mail. You do NOT need to remove the pump to change any of the O-rings except the one that seals the pump to the timing cover and that seals oil and is not your problem!

There are THREE that seal fuel, the control unit O ring, the LOWER head O ring, and the thick O ring that seals both oil AND fuel to keep the two liquids separate. I've seen all three fail over time.

If you take the rectangular cover off the side and there is diesel there it probably needs resealed. I usually start with the filter at the rear of the pump.

I think it's a 11/16. Unscrew it and you will probably need a pick to get the filter and o ring out. It's easy to replace and wont cost much. Good place to start. If you need pics or more info I can get them. Good luck.

I looked at it... what caught my eye was lot 95, the Super 88 standard. My goodness, sold for $18k+ USD. A couple people really wanted that thing. I'm going to start advertising our sale tractors in Australia. Ha!

For what it's worth, if it ran ok it's usually not the injection pump. I wouldn't touch it until I've started at the tank and worked my way to the pump. New bowl strainer (if equipped), new filters, blow out the lines all the way to the pump and get a rebuild kit for the lift pump (or a new one) and go from there. I looked at the pics of your tractor. It looks like an older restoration with a really good pressure wash before the sale. Who knows what was going on in its former life, or how long it sat. That poor broken three point arm though....

Those PSB pumps are kind of built like an engine. The lower housing is a crank case thatís lubricated by engine oil and the fuel is kept separate up top in the hydraulic head. Not saying they donít leak fuel into the lower housing but it isnít to common. You can pop the inspection cover off the side of it to check this. If fuel doesnít come pouring out your pump is fine. Like J said, it is very common if the tractor has been sitting for the diaphragms in the lift pump to dry rot and dump fuel directly in the oil pan. That is most likely your source.

Thank you both for your thoughts.
I can step you through my actions so far if you have the time.
I unbolted the lift pump first, it does not leak and the manual lever produces a good pulse. The sump still drained diesel, l disconnected the injector lines from the top of the Bosch pump and the diesel still drained from the sump plug.
With the fuel tank cock shut the flow stopped.
I will look for the side cover plate of the pump and check what happens

Did anyone look at the online auction catalogue.
