Engines / Re: Lister lt1 fuel problem
« on: May 15, 2020, 04:00:39 PM »
Revisited the engine today and it's definitely an LT1, tried a whiff of easy start and still no joy, I even stripped the head off as I'm sure the exhaust was sucking and blowing but the valves were clean as a whistle!
How fast does the engine need to turn over whilst cranking?
Tried to upload some pics but it will not let me
Any other ideas? I'd love to save this dumper as it's an Aveling Barfors sd06, pretty rare as its front wheel steer and made when British Leyland took over the helm, so it's fitted with a Morris marina back axle, Land Rover steering box and smallest gearbox that I don't know who made

Any more ideas?
Cheers
Ian

Thanks for the replies Gents and I had Strong disposable gloves on when I was testing the pump delivery, I had an old boss when I was working on tippers who put his finger over an injector on a Leyland engine with serious health consequences!

I returned to the engine and once again cranked over the engine and no diesel atomised out of the injector, real head scratching time, I knew there was good pressure from the pump but why wasn’t it lifting the pintle? It must have been that the spring was too much pressure on the pintle so I backed off the top of the injector and sure enough diesel started to spray from the nozzle.

Should there be a spacing washer on the top of the LT injector? As it is I have backed off the top of the injector and there is a space between the body and the top of the injector , I put the injector back and tightened down the holding clamp and I now have White smoke emitting from the exhaust on flicking the compression lever, the engine hasn’t been started for years and I couldn’t get it to go, don’t shout at me but I think it may need a sniff of the old easy start to coax her into remembering what to do?

Thanks for all the replies

Hi Chris

How long was the dumper parked up for? The bryce pump is prone to sticking and sizing if left for periods and if the pump was on the cam stroke it may be stuck in a position that is not moving against the spring.
I'm assuming that it's a AC or type of engine with the bryce pump on the horizontal, this was the case when I bought a secondhand engine which had been stood a while
Hope you get it started soon

Thanks Scott,
It's baffled me, the injector when I put it on the LT engine is drier than an otters pocket not even a dribble, but on the AC pump it works fine

Engines / Lister lt1 fuel problem
« on: May 10, 2020, 04:57:05 PM »
Hi Guys and Gals
After some help please! I have bought another project, another dumper fitted with a Lister LT1 engine, I cranked the engine over after unseizing the gearbox selector and it spun freely but would not start. I removed the injector and attached and turned the injector around as well as the pipe to see if it was atomising the fuel, no joy, took the injector home and watched a YouTube video on how to free the pintle with a drill and all was good, went back down to the dumper and attached the injector with the same set up and still no joy, I put my finger over the delivery pipe and cranked it and there seems to be good delivery pressure from the pump as the diesel squirts out with my finger over the end, restripped the injector and when I put fluid down the pintle pushes it out the jets.
Now here's the weird part, I took the injector up to a road roller I have with a lister ac1 and attached it to that and the fuel could be seen atomising as it should!
Any ideas?
Thanks
Ian

Engines / Re: Lister AD1 not stopping on stop lever

I once had an AC1 with the same complaint.
I removed the crankcase breather hose and fitting, lifted the flat rubber disc, and beneath that is a fitting with multiple holes. I screwed this out using a snap ring pliers inserted into the holes and turned.
Looking through the hole I could see the top of the arm that moves the rack, and as I moved the Stop/Run lever back and forth I could tell that the pivot rod for the arm was bent slightly in a way that prevented the rack from closing fully.
The pivot rod is quite soft metal, and I simply took a screwdriver and hammer and Carefully and Gently tapped the end of the rod in the direction that it needed to go and that solved the problem.

Thanks I will take a look

Hi Cobbadog

Yes I’ve had the gear timing cover off and the rack has full movement from left to right?
It’s baffled me

Thanks for replying

Engines / Lister AD1 not stopping on stop lever
« on: October 29, 2019, 07:34:51 PM »
Hi All

Got the AD1 running after swapping over piston and cylinder from donor engine but once started it will not switch off by pushing lever from "run" to "stop" position, any ideas on what the problem could be?

Thanks

Engines / Re: Lister AD1 seized bryce fuel pump
« on: September 30, 2019, 07:30:57 PM »
Hi Cobbadog

Not quite running yet, freed off the pump and thought it was pumping but ran out of puff swinging it over!
Are you the same cobbadog with the liner roughrider dumper from classic machinery?

Cheers

Engines / Lister AD1 seized bryce fuel pump
« on: September 28, 2019, 01:42:15 PM »
Hi All

First post and a bit of a long winded one but if it helps somebody else then its worth it!
I bought an old stothert and Pitt roller fitted with an AD1 Lister which cranked over and had good compression but had not been started for about 5 years, troubleshooting indicated no fuel out of the delivery side of the pump and after stripping to down to access the bryce pump I could not get the pump out, downloaded a manual from petter and followed the steps, tdc and run lever in 10* of centre and it would still not come out! Brain idea, ill buy another engine and just swap them over, exactly the same thing with this Lister AD1 which is ex military with cold start primer on, took the side cover off which exposes the timing gear and the stop run lever was not moving the rack, few gentle taps with a bar and hammer and the rack moved into the middle enough to allow the pump to be drawn out, first lister I've worked on and it was a real head scratcher as no one mentioned that the rack could be stuck to the side and without stripping off the side I would never have known as the stop run lever was moving through full rotation.
Hope this helps somebody and I'm sure i will be back on looking for more help
