Re: 1967 990 engine block

I would guess if you put the sealant into the radiator it will not circulate thru the engine until the engine has been worked hard and the thermostat has opened. In cooler weather this may take awhile. Perhaps putting the sealant into the engine directly, like at the block heater hose would be an op...

Re: 1967 990 engine block

When I bought my non running 1965 DB990 with AD4/47 engine about 30 years ago it had a crack in block that had been welded but was leaking some coolant. The gasket had been removed from radiator cap to prevent pressure. I drilled and tapped a series of holes around the area and bolted a plate in pla...

Re: How to loosen this bolt witout breaking the lifting arm

Nice job on getting it out, thanks for sharing the photos. Drilling is always my last resort but sometimes its needed.

Re: DB Front Axle Problem -spindle/axle

I used a suitable sized socket wrench to drift out the old bushes with a hammer, did not need to use a press or resort to cutting. I got new bushes from ASC bearings in the US. In general I have had good luck finding new and used parts by finding the DB/case part number then putting that into the we...

Cropmaster or DB 900 color code in USA

After all the time I have spend on the fenders and battery box cutting, welding sanding and knocking dents out, I decided to try and get the correct color. From the DBTC website the correct color red is Hunting Pink (cherry), the British paint code is BS381C -BS538. It was apparently a lead based pa...

Re: Rear Lights

I think it is interesting to find out what the original tractors looked like and how they worked, but so far at least, all of my equipment has been modified to suite my purposes, preferences and budget. Cobbadog, Thanks for the additional info I am starting some painting on a 900. Will you you have ...

Re: By-pass valve removal tip

I think a quick light touch with 1000 grit wet or dry "sandpaper" is really more of a polishing step than sanding, it will remove small fractions of one thou (0.001") from steel. Removing even 0.0001" takes a lot of work with 1000 grit. With tight fitting parts like this I would be very concerned ab...

Re: Dynamo and regulator wiring

I suspect that how well a specific voltage inverter works may depend on how clean the signal is, it may work fine with a battery but not so good with a mechanically regulated generator. There is probably one out there that could be made to work fine. Sounds like a good project for an electrical engi...

Re: Dynamo and regulator wiring

Interesting discussions here, I found a comprehensive manual on the Lucas voltage regulator and generator. I was able to disassemble clean, adjust and got it all working (on a 900). I think the manual was on the web site found by searching on haynes. It has a lot of theory that may also apply to you...

Re: Spun bearing on 990

I do not have much experience rebuilding engines but would assume you will need a new connecting rod. I think you should be able to measure the crankshaft diameter to see if it is within spec (from service manual). Might be a good idea to pull the pistons out and try to get an idea of overall cost b...

Re: Hydraulic take off on db 25

I flushed out the transmission in my late 900 (pre implematic) with diesel. I had found the gauze disconnected and filled with water and crud. I think I have had just about every hydrauliuc component apart and cleaned (3ph valves, ram cylinder and TCU valve and pump). I don't know if diesel was the ...

900 seat and mudguard

I have started working on seat and mudguard. I have more time than money at this point so am trying to repair and reuse as many parts as possible. I know the seat support system is not correct but am not too sure what it is supposed to look like. I am repairing the battery box and am using a photo f...

Re: Cropmaster steering

As you turn the wheel back and forth look closely for any vertical movement in the steering wheel. This would indicate a problem with the spherical ball bearing at the top of the steering column. You may or may not see any sideways wobble. If all is tight at the top it must be something at the botto...
