Title: Graupner Schottel II metal gear upgrade?
Post by: Aramis76 on February 08, 2023, 04:27:42 am
Hello all,


I recently found an unassembled Tito Neri that i plan on building next year.


The kit came with 2 Graupner Schottel II drives (2335).


I have read that the plastic pinion gears inside the drives had a tendency to wear rapidly and some mentionned that a metal alternative existed.


Unfortunately I can't seem to find such parts.  Would anyone know where to look?


I would like to find those parts and have them ready for when i build this boat and do it right the first time.


Thanks!

I never thought about this!!


Thank you!


The description mentions the listing is for 1 gear, if I have 2 schottel, I would need to buy 4 is that correct?


I hope this seller accepts to ship to Canada!!

I just realized that the 2335 changed in 2017 for a new gear design, do you know if these metal gears fit both?


Mine are the black ones so i guess they are pre-2017

Hi Ray, do you mind if I contact you directly, I think i'll have a few questions!

I see the helicoil on their website, it's part  4.3303   but thats for their 70-BM,
It does look very similar to the 2335, I know they bought the molds back from Graupner, but are they the same parts?

Also, newbie question but those are for the bottom of the drive, on the vertical and propeller shaft right?

What about the gear on the motor shaft?

hi aramis76  they are just the same if not slightly better than the graupner ones as bauer modells has improved on thing


the metal gears are indeed for the bottom of the units the top gears are ok they dont need replacing 'just regular lubricant and there fine'! 


 it was always the bottom gears 'if they were plastic' that was the problem  another upgrade bauer did was to  belt drive the unit 'like you see on there site


 ( ive not used them ones myself )   and also they   add a thread on the output shaft so  you can use a prop with a thread   regards ray

I reached out to bauer modelle and they told me none of their parts fit the 2335.The shaft diameters are different they say...
