G head gasket?

[Freddy]

Well it looks like the head gasket might have been leaking on my 47 G. (I see no visible cracks, will magnaflux today) It was on the outsides of the cylinders towards the bottom. The gasket was black in a semi-circle in that area both sides. I priced Deere already and there price doesn't surprise me. Is there a head gasket set better than Deere? I have heard of o-ringing the head to keep the gasket from doing this. Is that wise? thanks again for your help.

Give the gasket # to your nearest NAPA dealer. Fortunate that it's possible to get the gasket from Deere, but they don't need to charge so much for it.

do a search on the internet. www.agkits.com or maybe this site. There should be someone selling a head kit, I had trouble getting one for my 730 but it seemed like everyone and their brother make aftermarket gasket sets for A and 60's. How are the head studs, have they ever been replaced or are they original. I've heard of them stretching over time as well causing the head gasket to blow.

 

[Freddy]

Checked local fel-pro dealer and the G-70-720-730 series is missing out of the book.

The engine has been overhauled sometime ago. New block and pistons with an unstyled head. New exhaust valves with 70 exhaust springs and rotators. As for the head bolts they have been out by the chew marks on them. Replaced Maybe, but I don't thinks so.

The unstyled head is more than likely your problem. It needs reinforced where the fire ring of the headgasket sits.

Search the archives on the pulling board on how to do this.

I checked around you need to go to JD for those models i got comeplet overhaul set sort ive for my 52 G no block or upper water pipe gaskets in the set cost $188.00

 

[Freddy]

yeah deere is 245 dollars for two extra gaskets. that kinda steep.

 

[Freddy]

Would it be better just to ditch the old head and get a cyclone head then? This is going to be a work tractor, not hard but it will have to earn a living.

 

[Freddy]

Kent, Do you have a good cyclone head? also I need a oil guage pipe. thanks

 

[TURNER]

I have a perfect head for a g that i would be willing to trade for the unstyled head.

If this is strictly going to be a "user tractor", then you'll be better off with the cyclone head. It will make quite a bit more power with the flat head, but you will soon tire of buying premium or race fuel for a working tractor.

If you arent concerned with making peak power for 300 feet, sell the flat head for $1200 to someone that really wants it and put a cyclone back on your tractor.

The head is being magnafluxed today, but I won't get it back till next friday. Where are you located and how much for the head out right? This head I have might be no good.

 

[Freddy]

thanks for the info. I wasn't aware that the unstyled head with dished pistons increased the compression that much. Hey I just saved it from the crusher. I only gave $400.00 for it. I have a little room to play with it monetarily that is. Although it is getting expensive fast.

If you do swap to a cyclone head it will require some extra parts. You'll need the longer head studs, push rods, rocker oil line from governor to valve cover that go along with the cyclone head.

 

[Freddy]

didn't think of some of those parts. Yes my head has a crack in it. the head shop says it is repairable and was most likely not the area that was leaking. I will need to wait to see what is best.

Freddy, you should be able to sell you flat head, and easily purchase a styled head..
