* Spill Timing – Prepare

Posted on May 18th, 2009 by ploughmyfield. Filed under General, TE-F20 Rebuild.


We are all eagerly waiting for the answer to your timing problem but there are other things in life as well as Ferguson items, guess we will have to wait a bit longer. I too am traveling to Scotland this weekend but not to do any running.I am planing to stop off at the Heritage Museum in East Kilbride looks well worth a visit.   

I was thinking if you purchase, or posibly make, one of those timing discs you will be able to set it up from the 30deg hole in the fly wheel  and do all the settings from that point, although I quess you will need at least the radiator taken off. Did you do the fine adjustment of the camshaft using the slotted holes in the gear wheel? Can you please do some pictures of the venier pump adjustment when you do it please?

Hi John,
I’m glad you like the site.
Please send a report and photo’s of the Heritage museum. I’m sure lots of others would be interested in your view.

Yes I will be making a timing disc. I have access to a (CAD)Computer Aided design package. I’ll be adding the disc as a download for you all to make your own. it’s a bit like blue peter here!

I will be do documenting everything I can john it’s an essential part of the website.

 

To Do

  • Make template for timing (30BTDC (hole in flywheel) 32BTDC spill timing point, 0TDC (just as a check for the valve timing)
  • Ask Holland brand workshops if they have a number one port swan neck I can borrow for the pump.
  • find a hexagon spanner to undo the nuts on the front of the pump.
  • Read the Manual agin and again.
  • Find some time when I can do it.

* Inspiration

Posted on May 17th, 2009 by ploughmyfield. Filed under General.


I hope you are all well,
The tractor has been the last thing on my mind just lately. We’ve had our son’s first birthday, I’ve been to Munich on business and next week I’m off to the Scottish island of Jura to run up and down the hills for 14 miles.

I don’t know when I am going to schedule some time to look at the timing, which still seems very daunting to me.

Funny I never thought of myself as being an inspiration to anyone so this email was a nice surprise. I’ve had this great email from Geoff who also donated £10 which will keep the website up and running for a month for everyone to enjoy. Thanks Geoff.

I was starting to well up by the end of your email. Then I got to the part about wind whistling through my hair. Geoff, I don’t have any hair! not to worry, I’ve never had any hair! Well once upon a time I must have. I’m only joking Geoff, Its nice to see all my friends loosing there hair now as well and getting really paranoid about it. I do like to tease them. Anyway back onto the subject of tractors, here is Geoff’s letter

Tim

Your site has been an inspiration and true motivator for me for the last
twelve months. I have a TEF of which at least the steering column is
1953. My engine is good, at least it starts, has good pressure and
smokes marginally less than the driver. The back end was less good, the
hydraulics at there on pace, and to their own agenda and the brakes have
long since lost any intention of doing anything useful. As my land is
fairly hilly, this has hugely restricted the usefulness of the tractor.

Hence I have started at the other end to you. The backend is in pieces
and being subjected to the shotblaster and/or wire brush on a piece by
piece basis. I did the wheels first as I needed a quick fillip; they
make a huge difference to how a rusty tractor looks and goes some way to
distracting the wife’s glance away from the hole in the bank balance
caused by this impulse buy.

I hope to have her running again by mid summer so that I can go some way
to doing much of the work I promised on the day that it turned up on the
back of a trailer.

I donated a tenner which woefully inadequate for the services that you
have provided: your site has cheered me, and provided greater solace,
than the three pints that this sum could otherwise have purchased.

Don’t get despondent because of your timing issue. If you know that
your engine is in excellent condition, and it looks fantastic too, then
some relatively ‘minor’ tweaking is a small price to pay for the pride
and general feeling of well being that you have every right to feel when
flying down the road in fourth gear with the wind in your hair and the
gentle burple of your engine as a glorious soundtrack.

All the best

Geoff

Geoff, I took the pump out of my tractor to drain the green sludge out of it (green sludge was one hydraulic fluid) With the pump cleaned and refitted and new hydraulic fluid it’s been great ever since.

* Spill Timing

Posted on May 5th, 2009 by ploughmyfield. Filed under TE-F20 Rebuild.


I took the tractor out for a first proper run.
I was disappointed. It isn’t running correctly, by that I mean after you have started the tractor it is reving very highly and I am unable to get it to tick over. There is a lack of power as I move the throttle lever down whilst driving along. The first thought was to change the length of the control rod that come from the throttle on the dashboard to the pump. This didn’t work and even screwing in the rod to its shortest position did not make the tractor tick over any slower.
At this point I reached for help in the form of a question to the FoFH Forum. (If you do any tinkering with your ferguson tractor and you’re not a member , you should be!)
The feedback I got all points to the spill timing as the point to start. Another problem the tractor is having is the black soot or smoke from the exhaust. Again black smoke represents a timing issue.
This seemed the most comprehensive list from a user called Jón

Idling speed adjustment.
( DO NOT rotate fuel pump for that)
The idling speed is controlled by the horizontal screw in the venturi body on the intake manifold .(the piece on which the rubber hose from the air filter is attached)
Warm up engine, fully close throttle ,slacken off the lock nut of the idling speed adjuster ,on the venturi body and with the throttle fully closed adjust screw until engine speed is between 440-495 r.p.m.(P.T.O. 160–180 r.p.m)Thighten lock nut.
If you rotate the pump to adjust idle you will change the spill timing which is critical to the exact degree given in the manual.
Here are two points regarding the spill timing .There are two positions depending on engine serial number if pre 109124 it is 32° BTDC if post 109124 it is 26° BTDC
Here are the possible causes for black smoke
1) Air supply restricted— Check air filter, guess you did that
2) Excessive fuel injected max. fuel stop out of adjustment or pump incorrectly calibrated. (this means to take the pump to certified shop, definitely not DIY job ) guess you had the pump served ?
3) Injectors not functioning correctly — Guess you had them served for a rebuild.
4) Spill timing incorrect, Spill timing is critical but you can carry it out if you have the service manual available. After that NO rotation of pump to correct for errors of any kind, or engine running problems.
5) Poor compression –not likely on a new rebuild !
6) Fuel syphoning from Kigass tank, that´s possible. I had this problem, –reason: leaking check valves in the Kigass pump.
You can probably eliminate most of these causes on your rebuilt engine except may be the spill timing and Kigass. Was that done by the manual ? which it definitely should be.
And congratulations with your “new” engine, certainly hope you get rid of the “bugs”
Cheers

I’m overwhelmed by the method to set the timing. I didn’t pay that much attention to this when rebuilding so I don’t think I’ve done it correctly as well as the fact I have to remove the front axle, remove the timing cover and the rocker cover.
I find the Ferguson User Manual confusing to follow to set the spill timing. Again I asked on the forum and had this very detailed response from René.

Hello Tim,

The re-timing is possible without removing major parts but very tough to do
without the proper tool. It can also mean you end up with the pump on a funny angle.

I made the tool required for a “vernier coupling” as it’s called in the manual. It’s the
splined inside as well as outside “bush” that’s in the pump drive. I skimmed of the outside
splines in my lathe and welded a piece of pipe and a T-bar on to it. Now I can turn the
pump drive as it is shown in the manual. Without this you need to turn the entire engine
to perform the “spill cut off” timing on the pump. If you want to take a crack at doing that :

For 32º BTCD timing the pump must be rotated on it’s flange edge 0.863 mm or .034″
I therefore suggest you set the pump at appropriate angle that allows fitting all pipes easily
and then take those off. Mark the pump flange and engine distribution case. Then rotate
the pump the required amount anti-clockwise (from drivers seat). Next set up a the swan
necked pipe and do the spill timing. Leave the setup in place. With the pump set at this
position remove the “vernier” coupling and rotate the engine two revolutions to place the
1/4 bar in the timing hole in the flywheel. Make sure that the pump does not rotate while
doing this. Then insert the “vernier” coupling. It is splined with one spline difference
between inside and outside so a position will need to be found that allows inserting it by
rotating the coupling a spline at a time. With the coupling in remove the 1/4″ bar and
rotate the engine two revolutions. As you approach the position at which the 1/4″ bar can be re-inserted check the spill timing. It should be exactly on the point you can insert the bar.
If not start again. If ok you rotate the pump until the marks made earlier are in line to set
it for 32º.

Regards,

René.

Now I’m sure if someone showed me how to do this it would be really easy, but to follow the instructions I just can’t imagine it and I think that’s half the battle. It just seems really complicated. Can someone use the pipe from injector 1 as the “swan neck” pipe?

Read Geoff’s Spill Timing article here lots of images but could do with more. It seems easier to follow with pictures.
