lucas cav injection pump

Jim Mckay i have a backhoe with a lucas injection pump that is leaking fuel from between the main pump housing and the round section at the end that the injection lines attach to . i cant find any info or exploded diagrams to show what kind of seal needs replaced or how to safely separate the two sections . any help ?
thanks - Jim

Deewight Jim: Very rare to have that pump leak in that area. Are you sure it's not one of the banjo bolts spraying fuel at that area. Make sure area is clean and dry, (brake cleaner and lots of air). Get a mirror and have someone start it up while you watch. If it is indeed leaking where you think it is, pump will have to go to injection shop.
Jim Mckay definetly coming from the housing . i removed the throttle section fron the top of the pump and when you blow compressed air at the leak it bubbles right between the two section inside the pump. you can see this area clearly with the throttle section off. i have the skills and experience to repair my self , i would just like some info on the pump before i take it apart and have to wait for parts i could have ordered ahead . also easier to know if and how the two secions are timed befor separating.
Lorraine Hillman I have that same leak. I replaced all my banjo bolt washers and the leak drips about every 10 secs. The same as before I changed the washers. On another post some one takked about an o ring seal between the high and low pressure sides. Could that be the seal and is user servicable?
Paul Taylor I have the same pump Lucas CAV
I had all the seals destroyed in an engine fire and had to dismantle it to replace them. I found a manual for the pump. I have emailed the manual to you. If you feel confident to dismantle it and replace the seals you should be able to buy a seal kit from a diesel shop for around $50
Let me know if you need any further help

Robert Smith I have a 1998 Case 570 LXT loader-landscaper with the lucas pump on the 3.9 liter cummins 4-cyl. Recently the pump began a slow constant leak from the throttle control lever that is verticle comming out of the top of the pump and hooks to the foot throttle on the platform. Paul could you e-mail me the manual also to , I took the lever off thinking I would find an easy seal to replace under the lever or that I would find the shaft bushing worn...which would have damaged the seal...but the shaft is tight as might be expected with 3500 hours on the machine....anyone know if I can replace that shaft seal without taking the pump off the machine......I don,t have access to a Case service manual to describe the re installation of the pump
Weldon Foster I am in need of a manual also, I have a leak on the throttle stem and shut off stem on the top of pump. The manual would be very helpful!

Thanks so much, Weldon

PETER FIASCONARO I have a 1960 massey ferguson 65 with a lucas cav pump. The pump is leaking from a small plate on the bottom of the pump. The plate is held by a banjo bolt.I removed the plate and replaced all of the o-rings. however leak seems to be coming from the gasket between the pump and this plate. I tried to make a gasket but it just keeps leaking. any suggestions.

The modle # for the pump is --WW47E900/3/2470

It is leaking at the top shutoff and at each Fuel line connection.I don't know what kind of gasket's or seal's are needed to repair this problem I have read in this form about something call a Banjo Gasket this may be the problem.

Re: lucas cav injection pump

The picture is the C.A.V. injector pump on my 1972 Allis Chalmers with a 3 cylinder Perkins. The tractor runs great but the injector pump is leaking where the throttle stem goes into the top of the pump. The model # on the pump is
DPA 3230F350. Can anyone help with instructions on how to replace this seal. A manual with pictures would also be very helpful. Do I only have to take the top is the pump off which can be done without removing the pump from the tractor.
Thanks

steve i could use that manual also if it isnt to much trouble. thanks as far as the throttle shaft fuel leak, both the throttle shaft and manual shutoff shaft has 2 o-rings on them each. you can replace with unit on engine.
Doug Miller I have a ford major 3 cylinder diesel and have the same problem as Roy Monroe and would greatly appreciate a copy of the diagram of the Lucas CAV injector pump. Thanks,
Terry Presnal Be careful doing this oring replacement. It looks super simple and it was but now the dang thing will not run but when the thrtottle is held wide open and then it will only idle. If you move the trottle shaft back towards idle it cuts off. I took pictures of everything before i took it apart and put it together just like it came off. I don't know what the issue is. Im pulling my hair out with this one.

Eamonn ok going to try and help people who cant get fuel to the injectors, some of the posts above , I had the same problem on a ford 3600, similer pumps on ford 2000, 2600, 3000, 36000, 4000, 4600, and on Massey Ferguson, first check timing on tractor, it will give you reading of -12 to +12 on 3600 the setting is zero,setting/timing can be found on were pump is attached to tractor, now you can remove pump, when pump is off remove top of pump carefully there is a spring holding the top and bottom together, take note what holes your spring is in as it has to go back exactly as it was, to clean inside metering valve I used a toothbrush and wd40, and carbarater fluid, there will be a lot of grim in there free up metering valve,I did buy a new gasket,was told a gsket sealant would do I did not like that option,now just but the whole lot back together, it took me 5 hours but I was working slow making sure every thing was right as I went along, loosen injector and bleed screw, thighten bleed screw when diesel appears, could take a few mins before diesel reaches injector, hope this helps some body,

where can i find this injector pump?












































Mac My Lucas CAV was leaking around the cut off valve. After removing the top and replacing the O rings, the cut off will not work. The little tit is in the slot on the cut off arm, but it only revs up when it is turned either way. Seems like it is not able to idle down past 1000 rpm. I am wondering if maybe I have somehow messed up the metering valve, or just not put it back together correctly. It would be easy to fat finger that little job.
Any ideas/ help out there?

marshall Have a Massey Ferguson 1105 with a perkins 6 cylinder and the injector pump is leaking around the throttle shaft. Can this be fixed without removing the pump and if so how? If i had a manual im fairly certain i could figure it out. Any help would be greatly apperciated... thanks

It would be greatly appreciated.
