Found a good used pump. Spot on for age and config. 8 bolt cover Vertical mounted No pre filter Early excess fuel lever SPE 4A 70S 296 Serial #39058 And a good used drive shaft. Will fit and test after a service on the pump and good check over. https://i.postimg.cc/Vrvrc3qB/IMG-3526.jpg https://i.po...

Have purchased a replacement pump of the correct age and serial range. Also a replacement drive shaft as mine had damage. And the correct fuel pipe. Pump is in good used condition. Will give it a service and test then decide if it needs refurb. SPE 4A 70S 296 Serial #39058 https://i.postimg.cc/Vrvrc...

Thank you, will take a look.

Thanks, see other post on pump identification. I think the 296 ran later than 39001.

Very hard to find any info on pump numbers.

I agree, would be good to get the correct pump for my engine #.

The eight bolts on the cover appeared on pump no. 34624 (tractor no. 1271510),, the pre-filter dissappeared on pump no. 39001, the inclined 10º pump started at pump no. 52205, and the new button type excess fuel device appeared on pump no. 61994 (tractor no. 1299000). From here to 1425097 I reckon ...

So i took the pump for refurb and it is a mess. Bearing collapsed, hence the coupling pad breaking as the pump basically locked up. He can rebuild it, but.... the lobes on the camshaft are quite badly pitted and no replacement is avaialble, so it would just be polised up. And the follower rollers ar...

The bottom slot is no longer a slot, it is half missing, not clear in photo...

Found what appears to be a 380 pump, without pre-filter. Hard to tell if its vertical or 10deg ? Those curly pipes are interesting. https://i.postimg.cc/4nmDCLTF/s-l1600.jpg And what i believe i would have had originally, vertical, without pre-filter, 8 bolts. This is a March 1954, mine is July 1954...

Yes just the pad failed, but for many years the coupoling has had a pieve missing, can just see it in the photo above, the slot for one clamp bolt has broken away, another bodge, it worked fine but as im replacing the pad will repalce the coupling. Agree, it appears to be old damage. Almost certain ...

The clamp bolt was tight, no play before taking it off. I think this is an old shaft damage, probably from when they replaced the pump (Over 40 years ago at some point it had an earlier pump fitted). Pump doesnt feel good at all, will drop it off this week and get it looked at. Have a new complete c...

Well a quick update. Fuel pump coupling broke last week, made a terrible noise. Have removed the pump, feels rough, going to have it looked it. Maybe the pump was on its way out after all. Interesting when i took the pump off, the keyway slot is not as i would expect. Take a look. Key is also damage...

I had a milky white dipstick when the tractor sat around for a long time without use and only started occasionally.

Drained the oil (well) and changed it, filter etc.

Not returned since.

What pump serial number did the 380 pump start at?

Thanks Sandy. Im still open to the "needs hard work". The thing i find hard to accept is that for many years it never had this problem, many Majors dont get any hard use,just show tractors, and they dont bellow smoke like mine, something feels up. Today i checked the pump diaphagm, i took the two pi...

If you are sure there are no leaks on the vacuum pipes then the air supply side of things checks out. I presume when you had the air cleaner hose off you checked that the venturi in the inlet manifold was opening and closing correctly when the throttle lever was operated? Did you try SvendH tip of ...

Thanks Sandy. I found the pump serial number, 20228B Sounds a bit early for my 1286920 tractor ? Yes still working through the list of possibles to stop it smoking. It started smoking a good few years ago, no reason i recall. Check timing a number of times, injectors reconditioned, when you give it ...

Someone has plugged it both ends.

Been like it for a very long time.

Will buy a pipe and get it back in service.

Some people.....

Thanks

Thanks.

Mine is blanked off......

Consequences if any?

Where does (or should) it go?

The pipe goes into the head and then.........

Thank you Sandy, thats great info. So it would seem the 4 bolt pump was fitted to models ealrier than my 1286920. I suspected this is not the original pump due to the botched fuel pipe fo the pump. With the 10 degree pumps, is it the pump or the mount bracket that is inclined? Can i fit a 380 pump t...

Up until tractor number1380938 the serial number was stamped on the top of the clutch housing immediately behind the starter motor, there was no number stamped on the engine and the numbers on the clutch housing and the serial number plate should be the same. So where does the number 1302950 come f...

Got it running, was as suggested here, thanks for the advice, saved me some time! Wasnt easy to get access to the top of the followers with anything to give them a tap, but managed it with a plastic drift, turning the engine over by hand and tapping each one until they eased. Cleaned it all out and ...

Thanks, found a video of a working pump internals and makes sense now.
Will do as suggested as see if they want to start moving again!

Thanks, have given the insides a soak.

Are you thinking item 16 in this diagram is stuck?

Hi all, Just went to fire up the major for 1st time this year and no fuel to injectors. Took side cover off and when turning over the springs/pistons arent even moving? Rack slides freely, just no sign of movement when turning over (input shaft is turning ok) Any initial thought welcome before i dig...
