Rick

My Cropmaster is stored at my sons farm. I can get the measurement for you next week when I am down there. Hopefully someone can get you the answer sooner than me.

I took my old Cropmaster bearings in to a local bearing supply in Brisbane and they matched them for me. I had less luck with the seals (but you should still try) and I rang David Brown Parts in the UK www.davidbrownparts.com and they were here in a week. And yes the bearings are now worth more than...

According to a factory publication a Cropmaster could do 17.96 mph (on steel wheels!!!!). That would have shaken the fillings!

Cropmaster's first show -Allora Queensland

After days of summer rain and assurances that the show would be on I loaded the Cropmaster on to the trailer and paddled to Allora, Queensland for the huge annual tractor show. The rain got steadily worse but the tractor enthusiasts turned out anyway. I was surprised to find only 3 DB's on the field...

Cropmaster finished

With a few last minute bugs sorted out our 1949 Cropmaster is finished and should be at its first show this Saturday. The project has taken about 15 months and was a father and son effort. The dear old thing had been left in the open for many years and so there was much to be done. I would have to s...

I think the BS paint standards have been pretty consistent over the years. I took the BS number down to my local auto paint shop here in Australia and they found it converted directly to Australian Standard R15. R15 is called by many names depending on who you buy it from but mostly known as Cherry ...

Thanks Jim -great clarification. That sent me scurrying for my parts books. I have a 48/09 version and the 52/07 version. The earlier one shows just what you describe. According to the book my engine (P21025) should have the later type oil feed with the drilling in the camshaft but perhaps someone s...

Missing oil feed hole

I removed my camshaft yesterday and there is no hole drilled in the last journal of the camshaft for the interupted oil feed to the rocker shaft. It is just not there! So was this a faulty camshaft installed when the tractor was new (unlikely because the rocker arm would have seized fairly quickly) ...

I acknowledge your great knowledge of DB's Powerrabbit but my Cropmaster engine spare parts manual marked D5207 lists 2 straight 'gasoline' engines for the Cropmaster types AG 4.3.31/2 and type CAG.4.3. Perhaps straight 'gasoline' engines where only sold in markets where 'kerosene' was difficult to ...

The plot has really thickened now. I discovered that the reason the previous owner had moved the oil feed to the rockers is because there is no oil being pumped from the hole into the camshaft oil galleyon the right hand side. I can see the camshaft bearing and journal and it seems to be lubricated ...

Thanks all for the help. I think i have worked out what is going on. It seems that the oil pressure gauge line should be screwed into a fitting on the left hand side of the block (behind the filter) and the oil feed to the rockers should be screwed in to the block on the right hand side. Previous ow...

Powerrabbit Thanks for the diagram and explanation and my pipes etc are exactly the same as the diagram. My problem is that there no fitting in the block for the pipe 18 to screw into. Banjo bolt 17 screws into the block to hold pipe 16 but where does pipe 18 screw into. I will study things again to...

Thanks for the advice -behind the filter is the banjo for the oil feed to the rockers. So I guess it must have been attached there somehow although I cant see any evidence.

Could anyone post a photo of what the connection looks like please?

Cropmaster oil pressure gauge feed pipe

Hello all. Working to finish my Cropmaster restoration in time for the Allora Heritage Festival in 2 weeks. Can anyone tell me where the feed pipe for the oil pressure gauge is taken off for a 49 Cropmaster. When I got the tractor it was tee'd into the oil pipe that feeds the rockers but this set up...

RE: Cropmaster Restoration in Queensland nearly finished

Powerrabbit Thanks for the kind words. Having seen all the discussion over time go on about how we should paint the DB's when we restore them I decided to try to do it the same as the factory built them. Page 182 of Gibbards book shows a photo of a Croppy being painted with red overspray all over th...
