SOHC's vintage lawn tractor

I wonder how well it would run on kerosene? the fuel lines run from both tanks to 2 different locations on the carb. 2 of the bearings I need to remove are in blind holes, dose anyone in Auckland have an internal bearing puller?

Found another problem, the chain drive for the rotatory hoe has an open hole in the cap as the plastic is broken witch has let water into the chain case, I took the drain plug out and a drop of water came out, then I found it has a rust hole in the outer cover, I bet the chain and sprockets are fucked as its seized rock solid, if I am lucky the sprockets will be usable and I can just replace the chain and weld up the rust hole.

Engine is back together, unzezed and all crap and rust cleaned out, valves and seats recut, and end floats corrected, tappets set, points gaped, ignition condenser moved to outside of engine rather than behind the flywheel, I have the head bolted down now.

Need to find a strong person to help me lift it back in, I got it out myself but it is over 90 kgs 

The PTO shaft is actuality the end of the cam shaft, its huge like 1 1/2"

I will try to get some photos tonight but I got the hydraulics off and both the outer and inner PTO chain case off, things seem ok, chain was totally seized, but the tension devices and sprockets are ok, the top bearing is totally fucked and thats why it wouldn't turn, outer cover needs some patches welded in, I had to cleash 3 of the bolt heads off so they need drill ing.

 

Why do people leave shit out in the rain

Some ding a ling lost the oil filler cap off the chain case so it filled up with water till the cover developed a rust hole, that chain is a unique size to, the inks are about 25mm wide, I had to clean it up and reuse it, I could get a replacement of the same pitch but the spacing between the plates is a little wider,

those bearings were in the gearbox side cover, they where stuck to the shaft so hard that it made it impossible to get the cover off, I had to make yet another jacking plate, welded up the holes in the cover and boiled the chain in oil

Been working out how the complicated governor rod and spring system works, turns out the bush was seized to the arm so it wasn't moving how it should. Going to start on the carb next, its like a Tillitson style, the main kerosene float chamber in under the center and the petrol starting is in the square one out the side, choke rod is seized like everything else. turns out the tractor is a lot older than I 1st thought, it has a slieaniam rectofire for the charging system witch would make it from the 60s.

Spent a few hours taking the clutch apart and cleaning it, it was stuck like chuck and full of rust and crap, fitted new bearings to, the blue thing on the right is the hydraulic valve and reservoir, the ram is on the bottom, that was another shitty job rebuilding it.

I did the carb to, took a lot of time to get that apart with out fucking something. the accelerator pump diaphragm mad gone hard and crispy long ago and had been removed but the piston was there so I ground the top off the rivet and made a new diaphragm from an old fuel pump diaphragm, it would of pissed fuel everywhere before. put the engine back in and made a new horizontal exhaust.

It should hardly get warm with this charging system, its using the tin plate as a heat sink, I tore the old exhaust system off by hand it was so rusted out, it had 1" tube and some plumbing fittings to make the shitty vertical stack witch filled the engine with water, I reused the muffler and 1 7/8 tube to make a better sysrem

If I had a bulldozer there would be alot of work for it around my place, about 2.5 KMS of gravel driveway witch all ways needs work as there are 24 houses off it, 

A bulldozer with a grave digger on the back would be ideal.

I just need to put gearbox oil in this and it should go, I have the primary belts off so I might fire the engine up tomorrow.

I had to order in some 90W gearbox oil as its not available anywhere they just sell that LS hypoid gear oil, the fucking bottles have a picture of a gear stick on them but you carnt use it in a gearbox.

It runs, only after I discovered I had the adjustable main jet closed, opened that a bit and it fired right up, I was fucking round for ages trying to figure out why it wasn't picking up fuel and ended up taking the carb off ans apart. Also the rev counter and hour meter were not working until I remembered I have the primary belts off and that drives off the gearbox, another Matt Damon moment. Just out of interest I tested the old slieaniam retrofire by connecting the + DC output to a battery and seeing if the diodes still worked witch they didn't at all as there was 12v at the AC input terminals. when the gearbox oil arrives I can go for a drive.
