I purchased what I was told by the seller, to be a "partially restored" 1975 C Series. I have it now for 3 seasons & have concluded that this restoration consisted of replacing a few bolts and repainting it and replacing some of the decals. The seller told me he "screwed up" on the Model Decals when he ordered them, & put the wrong one on it (C120), but did not tell me the correct one that should be on it, and he gave me a 1975 C Series Owners Manual with it. I am wondering if the Model Numbers correlate to the horsepower of the engines. If that is the case, I must have a C100, because mine has the Kohler 10 HP engine, which is labeled as a K241S. It has an 8 Speed Manual Transmission.
After getting it home and using it, I put it in my shed & the next time I went to use it, I see the transmission/gearbox has leaked oil onto the shed floor, appears to be coming from the seam between the two halves of the rear-end. I also see a heavy black greasy film build up at both axle seals & also around the brake drum seal. I am now in doubt of the recommended oil for the rear end. Some of the online forums say that they had begun using transmission fluid as a replacement for older types of lubes, while others say 10-30 motor oil. I saw someplace which I can't seem to find again right now, that 85W-140 gear lube was what should be used. The oil level on the dipstick has not dropped to low levels, and appears to be motor oil, so after searching around and also checking the manual given to me with the tractor, I top off the level with 10W-30 as spec'd on page 5 of the manual(if this is indeed the right manual for my year and model).
My problem now, is that last season, it suddenly seemed to get a bit sluggish & slow down as it gets warmer during use. I believe my sluggishness problem might be due to the leak in the box seam and possibly also the type of fluid/lube in the case of the transmission/gearbox. I had already tweaked the carb as best I could, changed the fuel filter, replaced the spark plug due to a hard starting condition and rough running, & it seems to be running fine right now except for a backfire when shutting it down. I have purchased a replacement carb for it that I have to put on now, & I am pretty sure I need to locate & change the points as well.
Anyway I am hoping that someone can point me towards the right manuals, by placing all numbers I have been able to find on it here so I can hopefully find the right service/repair manuals (hopefully as free downloads someplace online) for the different systems.
Tractor:
Model: 103909
Serial Number: 47404
Engine:
Model: K241S
Specs: 46636D
S/N: 6097616

101761 or 1017G1 ?(Cannot Read Clearly)
Any and all advice/info anyone can supply me with on this would be greatly appreciated! Also, any tips on good places to purchase reasonably priced parts would be good as well.
