TE 20 Condensation In Hydraulic Oil

Vintage Tractor Engineer — Thu, 10 Jun 2010 21:07:36 +0000

Just a couple of photos from the first day of filming we did for the Ferguson TE 20 Hydraulics DVD. In this shot the lighting and camera were focused on the work bench as we dismantled the pump.

Now take a look at the colour of the transmission oil that came out.

The oil clearly hadn’t been changed for years and water had emulsified with the oil to make this yellow creamy fluid. There was also half an inch of corroded aluminium deposits and dirt in the bottom of the oil reservoir.

The mixture of oil and water is caused by condensation forming in the transmission housing and then dripping into the oil reservoir and mixing with the oil. This is the reason for regularly changing the oil even if the tractor isn’t been used for many hours a year (like many Fergusons that are owned by enthusiasts). In fact the less the tractor is used, there is an argument for changing the oil even more often (due to the increased likelihood of condensation forming).

TEF 20 Engine Not Repaired

Well it’s nearly 18 months since we bought a TEF 20 with a seized engine. As soon as we got the tractor home we were eager to get started with stripping the engine and finding out where the problem was. But the TEF is still sat in the corner of the shed, so why is this if we were so keen to get started? Well I guess the problem is that the tractor belongs to us. You see, well what I mean is, we always have a long list of repairs to do to customers’ tractors – and they have to take priority. As a result the engine is still very much in one piece and still seized.

A few weeks ago one of our customers rang to say he had a TEF and the hydraulics weren’t working. Could we go along and take a look. So we did and after a quick initial assessment decided it was going to need a full strip-down of the hydraulics. The next day we went back armed with a tool box and the video camera. And that was it, the TE 20 Hydraulics DVD was now been filmed.

What about our TEF with the seized engine? Well it’s still there and we intend to get to it as soon as we can, although we’ve got Joe’s TVO35 to work on first – it has a frosted block so Joe has found a second hand block to swap over.

In the mean time, the Hydraulics DVD is to finnish off which will take me a few weeks to edit all the footage and author the DVD onto disc.

Ferguson TE20 Website Resources

Vintage Tractor Engineer — Sat, 29 May 2010 14:13:09 +0000

If there’s one model of tractor that’s written most about on the internet it is probably the Ferguson TE 20. That’s not really surprising in itself, as there were well over 500,000 tractors manufactured between 1946 and 1956.

Vintage Tractor Engineer has decided to take a minute to put some of these resources on this page for quick and easy navigation (not just to help you the visitor, but also so Vintage Tractor Engineer can find these sites quickly and easily). One site, however, is a little favourite of Vintage Tractor Engineer – and that’s Tim Ray’s ploughmyfield site. What we like about Tim’s site is that it’s regularly updated, things are researched in detail and really well inllustrated with photos and videos – just like this post on a 4WD TEA 20.

So here are some links to TE20 resources. There are dozens and dozens on the web, so this is just a selection. If you know of any more that are of interest then please leave the link in the comments. Thanks.

TEF20 Hydraulics Oscillating Drive Strip

Vintage Tractor Engineer — Wed, 13 May 2009 17:28:13 +0000

Having problems with oscillating valve cir clip. How do you get cir clip in position inside valve. Does the valve slide? My old girl is in the 400,000 series. Acquired her last year, finally getting around to
refurbishing her. She still goes, but how so got me beat – more sludge than the black lagoon in back end of her. Any help greatly recieved.

Jed

Hi Jed,

Yes the valve slides.

There ws an alteration to the design of this component at serial number
407,102.

It would appear that the control valve and keyrod (or oscillating drive
strip – depending on version) can be assembled together whilst being out of the pump. This should make it some what easier to work on the retaining circlip. It is of the upmost importance for the circlip to be located correctly in its groove.

As long as the pump is not fitted to the tractor, the valve and oscillator keyrod/drive strip should simply slide back into its bore after lining up the square/slot.

Hope you have some luck.

Steve.
