Hi VP, that looks like a very robust puller, it should remove the liner without any problems. Stef is right that a temperature shock could help. Are you going to reuse the liner or replace it? If you are replacing it, run a couple of beads of weld around the inside of the liner where the liner meets the crankcase. As the weld cools it will shrink causing the liner to shrink and pretty much fall out.

My new shed is now erected and I will try to post some pics in the morning.
Keep up the good work,
Bob

Hi VP, Looks like you are making great progress, that bearing looks to be OK. Wen I was rebuilding my cooper engine the tapper bearings were severely damaged by rust, the two replacements were going to cost $500 each. I machined the housings to take slightly larger tapper bearings which only cost $50 each, worked perfectly.

Apologies for not being more involved in your rebuild but I have been a little busy putting up my new shed, I`m hoping to have most of it finished by the end of the week, I will post some pics soon.

Hi VP, I agree with Cobbadog, the bearings should pull out of the casing. It is hard to tell from the photo but is that a tapered roller bearing? If it is, the end float/bearing clearance would probably be determined by the length of the shaft and adjusted by adding/removing shims/gaskets under the bearing cover. I suspect the pin is there to stop the bearing race from falling into the casing during assembly or just an access point to allow you to lock up the shaft while tightening the nut on the shaft end.

Hi VP, nice work as always, can`t wait to see the look on your face when you finally get this 70 year old running.

Hi Vp, I think that lovely piece of German cast iron is way to heavy to ever get off the ground. Properly geared, it might be adequate to provide a tow launch for a glider. I did a lot of gliding in my youth and always hated the ground tow style launch because I didn`t believe the tow cable would detach and I would end up going nose first into the ground.
Are you hunting Bamfords this weekend?

Found it the hard way? So did the Wright Brothers.

I am looking forward to watching you try to get the Deutz to fly!  :laugh:

G`Day to you both. I totally agree with Cobbadog that you need to work through this problem logically, so there are four things that diesel fuel systems hate: dirt, water, air and leaks.
Start at the fuel tank, drain the tank and flush out the detritus, blow out the fuel line to the fuel filter. strip and clean the fuel filter assembly and replace the fuel filter. Follow the fuel pipe from the filter to where it enters the crankcase, remove the adjacent cover plate to expose the fuel injector pump. undo the banjo bolt on the front of the injector and remove the fuel supply pipe, be careful not to loose the two dowty washers or the small neoprene crankcase seal around the pipe. Blow out the pipe. Just above the banjo bolt you just removed, there is a bleed nipple, remove it and check the condition of the seal.
On the top of the fuel injector is a high pressure fuel pipe that runs up to the fuel injector, undo the pipe at both ends and remove it, blow it through.
Now put everything back together starting at the fuel tank, do not tighten the high pressure injector pipe where it connects to the fuel injector. Fill the fuel tank and bleed the fuel filter using the two bleed valves on top of the filter. Next is to bleed the fuel injector pump using the bleed valve above the banjo bolt. Let the fuel flow until you get no bubbles. Now (with the injector pump rack fully open)crank the engine over until you get fuel leaking out around the loose fuel injector pipe, when you do, tighten the nut.
Once you have checked everything is tightened (rocker cover and injector pump cover still removed), with the fuel pump rack fully open, crank it over while decompressed, look for fuel leaks around the banjo bolt and high pressure fuel injector pipe. Also check the fuel injector return pipe to the fuel tank.
If everything looks good try to start it with the rocker cover and injector covers still removed, don`t wear your best suit and please wear safety specs while doing this, you may get a bit of oil spray. If it starts have another good look for leaks, especially around the high pressure line between the fuel pump and fuel injector. If it starts and everything looks ok, turn it off and replace the covers, I recommend some gasket sealer around the neoprene fuel inlet pipe seal.
If it still won`t start after all your efforts I suspect that the fuel injector pump is worn and will require a new element. When they are worn they do not produce enough pressure for the fuel injector to spray diesel into the engine, they also tend to leak fuel out from the bottom of the pump into the crankcase. I hope this is not the case. Injector pump elements are readily available but I do not recommend you try to replace it yourself unless you are a Gun mechanic, take it to a diesel service specialist and have them do it. If you do have to remove the fuel injection pump be very careful to keep the shims that are between it and the crankcase, these determine the fuel injection timing.
Good luck, let us know how you get on,

Bob

Hi Cobbadog, a tractor without mud is  an ornament! Glad you had a good time, I`ll try to get up there in a year or two.

Hi VP, I love that governor mechanism, the Germans have some very skilled engineers and designers, that is a beauty.
A bit worried about the valve guides, 9 euros each as long as you buy 50 is a bit rich. My offer to do the machining stands but you will have to wait till my shed is finished and fully equipped.

Hi Mike, a 12 x 7 shed is luxury, I spent two years living in a caravan, after the bush fires. The local council and state/federal politicians all made a lot of promises of help. All just hot air, so I`m with you f**k them! Any officials comes knocking keep your head down and don`t open the door. If they don`t like it that`s tough luck, point out it`s just a shed and no one lives there.
My shed has planning permission but is not allowed to become any sort of residence. Once the surveyor has signed off that it meets construction codes, I will be fitting a toilet/shower and small kitchen area. Bicheno, Tasmania is a very popular tourist destination but there is no accommodation available for the workers. So a couple of bunk beds should net us a nice little income during the summer.
A couple of pics of todays progress.

Hi Cobbadog, saw your post about painting stuff for the show. I`m guessing that was the rusty iron in Macksville. I hope you all had a good time despite the wet weather and mud. I wish I could have been there but a bit of a drive from Tasmania. Maybe next year.

Hi VP,  So the two bolt holes need to be vertical with the piston at TDC, be careful not to get it reassembled a tooth out either way, it will be a bugger to start and run like a dog.

Hi VP, if the sleeve is in good condition I would just be replacing the O-ring seal, I would be replacing the seal regardless of it`s condition. When reinstalling the sleeve it can be much easier if you leave it in the deep freeze overnight. You might want to put a couple of witness marks on the block and sleeve before pulling it out, that way if there is wear in the bore it will all be reassembled as it was.

Sorry, the picture shows the lever in fuel off position. lift it a little and it is in governor/throttle control position, vertical is over fueling for cold start. Apologies, I haven`t had much time to play with these toys recently.

Hi Guys, the shed erectors arrived today and have had a fun day playing with big boys Meccano. They have assembled all the stanchions and roof trusses and are going to try lifting them into place in the morning.
A couple of pics attached.
