Hi,
I've Done it now, I broke my 933G Reverser. Not sure exactly what's gone wrong (broken shifter fork?), but I need a service manual to open her up and inspect. 
My first question is what service/shop manual do I get? The Machine serial number is 42A 8504 G  The used manuals I find say 42A1-up, but my serial number is 42A, so Im confused as I thought my machine being a "G" with a turbocharged 4cyl was the last of the 933 series. I see there are 42 A1 & A2's I would think those would be later than mine, just confused. 
Thank You for the help!

The Parts Book for s/n 42A5918 to 9202 (Form # UE036197) covers the "G" model with the D320 engine.
The Service Manual for 42A1-up doesn't cover the later models and I'm not aware of one that does.

Thanks.I really need the service/shop manual because I have no clue how to open the top of the transmission up with the steering clutch linkage going through that.
