Surprise
I was recently looking for replacement PTO shaft (Part No. 70050-94620) for in-between my F3060 mower and RC72R-F30 rear discharge deck, but was told by dealer it is no longer available from Kubota!
The dealer was unable / unwilling to offer any help at all for alternatives. The PTO driveshaft 70050-94620 was listed as a $600 part when it was last available.
This was totally unexpected bad news and prompted me to urgently start looking for alternatives!
After 3600 hours of use, the drive shaft spring lock yoke splines were worn, the extension spline was worn and the bevel gearbox end yoke fit to the gearbox was worn loose.
U-Joints were the only parts without any noticeable wear.
The design of RC72R-F30 (Rear Discharge) deck uses shear-bolt only at the bevel gearbox end and has no key-way in the shaft making it slightly loose fit over time, which probably caused the extension spline in-between the yokes to wear excessively.
After some online searching I found out that the old IH Farmall Cub tractor uses the same .098"-10 spline in the PTO output shaft end where the PTO shaft yoke is connected to, and Weasler Spring-Lok yoke No. 105-0610 has a perfect fit and will also fit the U-Joints Kubota uses (which are the same as MOOG 861)
Kubota F3060 mower gearbox output shaft end will connect with Weasler part No. 105-0610:
Item No. 020 is the internal gearbox PTO output shaft with .98"-10 output end spline:
All of these 12 Kubota F models use the same PTO gearbox output shaft, item 020 ( Part # K3511-14310) and have the same .98"-10 spline:
Note:
With that information I went to a local drive shaft specialty shop where the first thing I was told was Kubota uses proprietary parts and may be tough to find aftermarket replacements, but mentioning Weasler 105-0610 Spring_Lok yoke caught their attention.
Long story short, they made me a new PTO shaft out of parts found in Weasler North American Drivelines & Components catalog and the cost of new shaft was way lower than expected.
The new shaft fits perfectly and does not have any noticeable vibration - so far I have used it for about 4 hours.
It's good to have a local shop and alternative supplier, especially when the OEM stops support!
In all fairness I have been able to get all other parts for my 1996 F3060 mower, it's just the uncommon rear discharge deck they have apparently stopped supporting.
All PTO shaft parts for the RC72R-F30 mower deck can be found in the Weasler catalog, pages 7 thru 11 and I think they were the source for the original US made Kubota RD deck PTO shaft parts.
I will keep you posted,
Cheers
