Fergie engine upgrade

[Johnny R]

My TEA-20 engine needs overhauling. It has the Standard 85mm engine. There is a engine rebuild kit that is 87mm that they say will fit my engine. Also claim some more HP. Have any of you guys installed this kit in a TEA-20 standard engine? If so, did you run into any problems?

Careful with this upgrade Johnny , it seems that some kits require the liner seats in the block to be machined lower to take the larger liners . An expensive process and one that is difficult to get done.

I'm with Charles here. You could open up an expensive can of worms for no reason.
A rebuilt 85 is as powerful as a grey fergie ever gets- or should get? Like the octane findings on the US news this week, how much more power you going to get for what you will pay in extra $$? This 2mm job might not justify the time and money.
And mine wasn't a hard or expensive a job compare to some. A new clutch while it is apart, and loaded tires (tyres) and you might be impressed.

I would not do it either. Just thought that I would say hi to a neighbour.

Good morning Johnny R. Glad to see you have a great Tractor TEA-20......

Have you ever overhauled a TEA-20?

Do you have the service manual for the TEA-20?

Plenty of experienced gentlemen on "YT" with TEA-20 experience.

If your engine needs overhauling it is bound to be down in power. You might be surprised at the improvemrnt of a properly done standard overhaul. Why burden 60 odd year transmission with more power than it was designed for??

Hi Ron, What part of Ont. are you located?

 

[Johnny R]

Hi Charles, Changed my mind on the 87 mm kit. Going with the 85mm kit. Not worth the costs to get a teeny bit more hp.

 

[Johnny R]

Going with the 85mm kit. Brother will do the rebuild. He's a tractor mechanic with many overhaul jobs under his belt. He knows the Fergies inside out.

 

[Charles in Aus.]

A wise decision I think Johnny.
Besides to get all the up of a 35 engine you would most likely also need a 28G carburettor and a head with lager valves .

Hi Ron, What part of Ont. are you located?

Near London. What about yourself?

You should consider doing the overhaul yourself, and just use your brother for guidance. :wink:

I intend to do the work with my brother, having him for guidance. I live near Waterloo.
