Re: live grive gearbox

Hi The oil seals I am referring to in the pto gearbox prevent oil from moving from the gearbox to the rear axle and vice versa, in other words INTERNAL oil movements. If you have a pool of oil under the tractor is it black oil? If so it has come from the engine rear oil seal behind the flywheel and ...

Re: live grive gearbox

It is more likely to be engine oil coming out of the bell housing split pin. As Sandy says it will be black and smelly if it is coming from the engine, if it is oil coming from the gearbox input shaft seal it will be cleaner looking. When you split the engine from the gearbox you will he able to see...

Re: FPM oil from crankcase breather; coolant pouring out

You have probably got to the bottom of the problem. The blockages in the rocker cover metal outlet tube and the pipe from the cover to the air cleaner would have prevented the engine breathing system from operating properly, and excess pressure from piston blow by would have escaped via the little o...

Re: live grive gearbox

Well Sandy, I am assuming that it will be a complete unit, if the internal primary gearbox is taken out of an assembly then the rest is not much use to anyone else! Not many people will be aware that it is possible to do this in any case. Perhaps " hazard " can enlighten us?

Re: live grive gearbox

As the gearbox is being changed to a live drive version the original gearbox will have to be detached from the rear axle anyway and the replacement live drive gearbox will come loose and thus replacement of the rear output shaft seal on this gearbox before it is fitted will be an easy job!! There is...

Re: live grive gearbox

I would definitely fit a new gearbox output shaft seal, this is in the housing held by four bolts on the back of the gearbox, and I would most definitely change the two PTO auxiliary gearbox seals that are fitted back to back in the PTO auxiliary gearbox - you will have to unbolt the PTO auxiliary g...

Re: FPM oil from crankcase breather; coolant pouring out

If the tractor had been running without problems before then it might have been something as simple as a thermostat that failed to open, resulting in the engine overheating and causing issues with the pistons and rings. How long did you leave the engine running for before you came back to it? Had yo...

Re: New user, new project

What the video shows is not so much the governor responding with the diaphragm and rack moving the pumping elements, but more so the elements minutely moving the rack and diaphragm due to vibration and bounce, this is what you normally see.

Re: New user, new project

No, the principle of governor operation will not cause that to happen. In the case of the vacuum governor, this works on the basis of maintaining a constant vacuum depression in the inlet manifold, the depression is dependant on the engine speed but the governor will select a setting that maintains ...

Yes Old Hywel, I agree with you, they are all independent pumping elements in an inline pump so the status of one cylinder cannot affect the others. The pressure developed in a particular element, pipe and injector is entirely down to the condition of that pumping element, the integrity of the pipe ...

Re: Injector issue

If the tractor has not run for 10 years and there is no obvious sign of water and corrosion in the pump chamber it is likely that the plunger has seized in the barrel through "gumming up" - that can happen with diesel fuel as well as petrol. The machining tolerances between the plunger and the barre...

Re: power loader possible?

The Super Major is better suited to this sort of set up with it's auxiliary service valve, this isolates the lift cylinder completely from the equation and allows the pump to supply just the trailer pipe tapping, and the relief valve will re-set automatically after discharge.

It is easy enough to set up, all you need to do is fit a pair of double acting spool valves supplied with oil under pressure from the hydraulic trailer take off point on the lift cover, and a return pipe for the low pressure return oil plumbed into the oil filler cap on the lift cover. The lift leve...

The same number should be stamped on the flywheel housing flange immediately behind the starter motor on the left of the tractor.

Hi Is this a 3000 with an inline pump (and lift pump ) or one with a rotary pump? Obviously the inline pump has the excess fuel button so a tractor that needs ether to start despite using the excess fuel device has other issues such as low compression due to wear. If it has a rotary pump then the 30...

Re: Meshed gear noise when being pushed in neutral.

As everyone says, with a combination of spur gears and probably twenty to thirty thousand hours use you are bound to get some transmission noise in the old Majors. The original oil seals in the PTO gearbox also fail after a while and this allows oil to drain from the gearbox housing, which is at a h...
