I am considering the purchase of a 350 crawler and as I am not very familiar with these I have some questions. What is involved in repairing the reverser, why does it have a reverse gear if it has the reverser and should the 4th gear be blocked off? Type is 4F3D, SN is C 3276 I. I am not sure the I is correct and it was not easily legible.

The 350s were available with, or without a hydraulic reverser and the same gear transmssion was used either way. So, a 350 with the optional reverser would have two reverses - and of course, if you put both into "reverse", the crawler goes forward. The later 350s, I think starting with the "C" series, made the hydraulic reverser standard equipment, and thusly, left reverse out of the gear transmssion.
As far blocking out 4th gear? If you don't want it, don't use it. It's not a danger, just to fast to be of any use.

Any ideas as to what could be wrong with the reverser?

It's kind of hard to guess without seeing it or having any symptoms described. It is a fairly simple unit but you can't do much without removing it - which requires pulling the engine first. Most problems come from bearings going bad. The main shafts are composed of an imput shaft and an output shaft, with an inadequately sized bearing where they come together in the center. When in forward, the two shafts are locked together and the little center bearing does not turn - but when in reverse, the shafts turn counter to each other and a high load is put on that center bearing. When it wears - or burns out - the entire assembly gets loose since all the bearings are Timken sytle adjusable tapered cone bearings. Early 350s and 1010s have the smallest center-bearing and there are update kits to put a larger one in. Later 350s already have the larger center bearing. Again, the whole device is much simpler than an automatic transmssion in a car - but the parts cost a lot. A thorough rebuild usually entails a new pump, two new clutch packs, a new hydraulic manifold, seals and bearings, and checking various small parts in the control valve assembly. You will probably need a new driver-assembly on the flywheel also. Early models use a spring-loaded clutch plate disk, later models up to the "C" series use a convoluted and trouble-prone spring/hook/plate "torsional isolator" assembly - real piece of junk that often flies apart and locks the engine up. The "D" series and newer have a totally different unit that is much more durable. I haven't checked parts prices lately, but I'm sure it's very easy to spend over $2000 in parts for a complete rebuild. If you are careful, check everything, but only repair or replace what is needed, you may get by much cheaper.

If you find other problems and it is not worth fixing then I would be interested in the transmission from input shaft thru ring gear, even including the case.
