I have a 1961 ES2 (62 model year)

Does anyone know if the oil pump is the same as on the Dommie/Atlas?

The pics look identical from what I can see.

Thanks in advance!

No - the ES2 oil pump has the oil outlet at the opposite end, when you study them closely. At least you didn't buy one to discover this, as many do !!

Maybe I should say this applies to earlier ES2s, I don't what happened in the 1960s, they may have altered the design somehow so it is common to the dommie. Caveat Emptor ?

thanks Rohan,

It had alternator and distributor by this point, and shared quite a few bits with the Dommie, hence my question.

If no-one steps forward with a definitive, I'll whip it off at the weekend and take some photos!

Cheers.

Yes its different.
As Rohan says it is a mirror image, but also the body is usually made of Mazak on the singles (although I have seen Bronze ones), unlike the cast iron on the twins and I think the sealing washer seat may be machined differently as well.
I think the gears etc are the same as the 500/600 twins but not the bigger ones.I have a 1962 Model 50 motor and its all the same as my 1959 ES2, I don't think they really changed much after 1947 except the heads and to accomodate the alternator etc.

They're not hard to come by ( the oil pumps, that is) I think anything after about 1933 is the same.


Oil is always cheaper than metal

We stripped it down at the weekend, and refurbed it.

It's now grit free, and spins smoothly!

Thanks all.
