Came across a wreck of a Bolens tractor and believe this to be the original engine.

 

Only clues I have is that it's a tube frame with a 3 speed box but there are no identifying numbers or marks.

 

Thanks as ever.

B&S carburetor makes me believe its a B&S engine

 

Pulley looks like one of the 70's 3 speed models like G9 or similar

 I thought perhaps Wisconsin???

 

But which one?

 

Don't know if it helps but one valve retainer has a couple of collets the other has an off set hole in the lower valve spring retainer.

no it is Briggs  I 1st thought Tecumseh as well. but with the legs to mount a coil + the carb + the 2 bolts on the head for the shroud means it's a briggs....

99% chance of B&S

Definitely not a Wisconsin

It's a Briggs Either 10 or 11hp if that 2 piece flow-jet carb is original

8hp briggs had the 3 piece carb

 

Got any Pics of the rest of the tractor?

 

:wewantpics:  lol

I have it in the barn at the farm next door so can't get pics in the light until Friday PM but will do.

 

Also which manual and parts catalogue  can I download which will cover it?

 

Thanks

Need to know which tractor model it is first.  Then look in the manuals section for that model or series and it will probably be there.

Here's the pictures you requested. Still none the wiser.

 

This will be a long "work in progress"

If it's a 10 hp Briggs then it's going to be a 1976 or 1977 G10. 

 

If it's an 11 hp, it would be a 1978 G11.

 

The odds say that it's the former.

Looks like its a bit of a franken tractor, that clutch is from an 800,900 or 850/853

Bit of an update.

 

Managed to do some quick and dirty measurements over the weekend. Removed the head and measured bore and stroke.

 

88mm bore (converts to 3.464 inches for my American friends) and 66mm stroke (2.598 inches).

 

Now using some of the downloads available in the manual section, if it is a Briggs then I reckon it's a H48 series 250000.

 

Just now need to find out what the tractor actually is but given Old Buzzards post I'm inclined to agree it's a G10.

 

What do you all think?

 

Am overseas again at the end of the week so limited to answering questions until I get back.

 

Thanks everyone for your help with this.
