Re: Date of manufacture.

What exactly would you like to know. It is almost impossible to know the day it was built but I worked on averages for my tractor and that was enough for me.

Re: Timing Gears

Scrappers are the only suppliers around here too. My 30C has a few chips off a couple of teeth and the idler gear from crankshaft to governor had quite a few half broken teeth. I then noticed a missing bolt that may have gone through the gears to cause the damage. Luckily a mate had a garden ornamen...

Re: Side Panels

You have to use a specially made press for cutting and forming the louvers. Hot Rodders used to insist on having them years ago then they went out of fashion and they are now making a come back. Of course on the tractors and crawler they are there to aid the air flow for cooling. Under normal situat...

Side Panels

These home made side panels came with the Super Cropmaster I had for spare parts and now will go onto the 30C. Hopefully tomorrow I can start putting some parts in primer and next week the sand blaster will be onsite, weather permitting.

Re: Oil Bath Air cleaner.

Thanks for the reply. Here in Australia it is called a swedge so that is why I called it that, no other reason and certainly not to upset you. But the manual does not say to fill both inner and outer sections and is why I asked. Ok, I will fill both sections to the line as there is a number of small...

Here is the inside but I had to compress it more than normal.

Oil Bath Air cleaner.

Hi I recently bought this air cleaner bottom section as my original was missing a clip so I did a swap and now I am cleaning this up ready for painting along with the rest of the tractor. My manual does not give a clear indication of where the oil should go and to what level. In the old one I only e...

Re: 1967 990 engine block

Yes Gard, you can weld using a specific rod with only a small amount of preheating but as I mentioned you do short runs and then peen it. Keep this up until you have welded the crack. In my case with the broken lug I "V" the area to be welded as deep as possible from both sides because I had access ...

Re: 1967 990 engine block

Can't imagine why the thermostat would need to be removed as soon as the engine warms up it should open to allow the sealant to circulate. I like the idea of a plate as well, simple but effective. Welding is successful when done correctly and if you are unsure of your ability get someone who can do ...

Re: 1967 990 engine block

With welding there are a number of different approaches with type and grade of arc welding rod that can be used. Some require preheating and some not so critical. Using oxy welding they can be joined and sealed using bronze rods. these will leave a distinctive wide fillet when done properly but it w...

Re: 1967 990 engine block

You can use a sealant but remember that will also want to start sealing the radiator core as well. Stitching is the best solution but so is welding. If it is in an easy access area welding would be my choice if you don't want to replace the block. What price is on the block advertised and can you be...

Re: Cropmaster Fuel Issue

Other thing to consider is the air hole in the fuel caps. I had a blockage that I was unaware of in the air hole and it would run for around an hour then stop. Re-start and it would go for a short distance then stop, finally figured mine out. As suggested check the fuel flow from the tap outlet goin...

Re: Roll Bar for a 1967 990

On the 30C which is similar that is where my full sized mudguards fit, but a roll bar could still be fitted at that piont.

Re: 1967 990 engine block

I've never had to buy one for any of the toys but I guess a few factors have to be thought about. Is it what we call a short motor which means everything is there but may need reconditioning or is a bare block where everything is missing and requires all the bits to be added? Have a look at other en...
