I removed a three speed Sherman from an NAA.The hole in the side of the transmission case had been be elongated about a 1/2 inch forward to except the shifter handle. I put this same Sherman in another NAA. This had the hole already there from a previous Sherman. I had to elongate this hole also about a 1/2 inch to axcept the handle. Does that mean two indivuals missed the mark?
 
Wild guess here on my part, but maybe the combo is a different
length than a step up or step down that was in it before?
I'm sure someone here will know for sure.
 
My guess would be that the tops might be different, since more than one style was made, along with shimming could cause the problem.
Step up handles are in a different location.

Hello Wayne , It is very possible the Sherman you have was originally in a Ferguson tractor . The Ford and Ferguson shift covers are different but the rest is the same , a half inch is about right because the Ferguson cover needed clearance for the steering box where the Ford does not . Also the Sherman Reverser is about a half an inch off but I doubt both tractors were Forklifts at one time . Thanks Tony
 
Hello Kirk , Yes there were different covers as you have two of the designs in your picture but you will notice the casting number is the same , all of the 4 cylinder covers have the shifter in the same place and shimming is usually about .050 max. . The cover in the right side of the picture is the better cover because the shift rails are enclosed and well lubed , the early design has exposed rail ends which tend to rust when not shifted for long periods of time hence the reason many early Shermans are stuck in gear . That design change was made in 1960 . The earliest Sherman I have seen has a serial number of around 65,000 as ALL Shermans are Stamped with serial numbers in the front of the case . Check the two you have apart and you will see the serial numbers on them and post what they are . Thanks Tony

Like Tony said, you likely have a Ferguson top cover on your Sherman. This picture of the Ford and Ferg covers shows shows the shifter shaft is about 1/2" further forward on the Ferguson cover.

The Ferguson top cover will work on a Ford, but the Ford top cover won't work on a Ferguson tractor.

The earliest Sherman combinations were gray and I've seen serial numbers with 3 and 4 digits on those many times. Lowest I've seen was 880 something.

Here's an early one I have in the shop now.

Thank for the information. I wasn't aware of all of that concerning Shermans. One never gets to old to learn.
 
Hello John , I should have known you may also be keeping track of the serial numbers . The highest Combo I have seen is about 71,000 and the highest Reverser is only about 5,000 . I also noticed after Ford bought out the Sherman Bros. in 1960 , they redesigned the Sherman molds to replace Sherman casting numbers with Ford casting numbers they stopped numbering them . All Sherman's with C0NN or C3NN cases have no serial numbers on them , have you noticed that ? I have not had many real early ones in the shop like that , probably out of a 1949 or 1950 8N ? Thanks Tony

Tony, I think the highest number I've seen on a combo was just over 76,000. I also have noticed the Ford cases weren't numbered. It was probably just for Sherman's record keeping. The case pictured above was out of a '49 8N.
