Re: Engine blow back

Or, are you talking about crankcase pressure?

If you are, I wouldn't worry about it unless it was in large amounts, they seem to do this. Check the breather on the rocker is not clogged up otherwise pressure will build.

Re: 995 oil leak

Clean out the system as advised, your oil is terrible. As to your friend, you need a better one! DB's are brilliant machines far ahead of others of the era. Massey are a well respected, reliable machine but as well as being vastly overpriced I would sooner have a DB any day. I'd put my 995 - or any ...

Re: 996 maintenance

The only antifreeze that is suitable is the ethylene glycol type (blue/sometimes green) and it should be changed every 2 years.
Do not use the pink OAT long life type, as this is not suitable.

A 50/50 mix is ideal in the UK.

Re: Question on the hydrashift

Well I believe the hydrashift was very advanced for its day, and David Brown probably just didn't go far enough to idiot proof the gearbox to the point that it could be driven incorrectly without suffering damage. Modern tractors still aren't all idiot proof, I see drivers that destroy clutches and ...

Re: steering ram

A good seal/bearing supplier should have no difficulty identifying and providing the required seals, I've yet to find a ram my local place can't do although they may not be in stock, so it may take a couple of days to actually get them.

Re: 1412 Adjustable track rods

As others have said, widening the front axle will do nothing to aid stability, it's all down to the rear wheels to hold it down. Ballasting the rear tyres with water can also be beneficial for stability, as can a counterweight. Personally I would keep the front wheel width narrow on a loader tractor...

Re: 1212 Wheel bearing slacked off? Cooling system troubleshooting

It is very rare for a water pump to fail in any way other than a leaking seal or failed bearing, they normally pump fine.

Unless the tractor is overheating then it sounds like everything is fine, as said above.

Re: Soluble oil as coolant

Modern coolants (like OAT) are not suitable for our old machines which is a shame as they don't need changing as often. I have no personal experience of using oils as a coolant but I have heard of it damaging rubber hoses. I really don't see what is wrong with using the correct Ethylene Glycol antif...

Re: cracked block

It's nearly always possible to grind it out and weld it cold with stick. You have to use the correct rods for welding cast iron to cast iron (rods for cast to steel will not work), do very short runs to keep it cool and peen the weld metal while it cools.
It can be tedious but it does work.

Re: DB 1190 - Hydraulic Oil Filler/Ram Seals

I can't answer the other questions but for seals the best option tends to be taking them to a local bearing/seal etc supplier who will measure them up and provide replacements.

Re: Hello to everyone

I would check the thermostat, no. 34 as above. It's not impossible that it's faulty despite being new. Dropping it in boiling water will make it open, there is a proper testing procedure using a thermometer to check exactly when it opens but as a rough test boiling water will do. When you say it get...

Re: Suburban newb with a tractor

Take the block and broken crank to the machine shop to let them assess the damage and how to repair it.
Assuming that they can repair it then buy a replacement crank, but it seems sensible to check that the block is repairable before spending money on a crank.

Re: 1594 injection pump questions

When the tractor is left parked do you leave the engine stop in the stop position?
Some injector pumps can have the stop stick sometimes, so it's a good habit to always leave it in the run position.
