Hello I would need help to find part number for sun gear shaft from final drive 242-1153 Motor GP-Travel That sun gear shaft connects to motor shaft 311-9649 Final drive was bought for parts so I don't have serial number of excavator it was installed on cat 301.8C
Not available from Cat as a separate part number, sorry. Whatever parts are serviceable from that final drive are only sold as kits. If it is shown as being part of a kit then you can get hold of it but only by buying the complete kit.
If the hydraulic motor has a tag on it you'll find who the manufacturer was (it won't be Cat), Nabtesco, HyDash are just 2 of many. From there you can find dealers who can supply the parts required.
If it's anything like others the tag will only have a Cat logo and Part Number on it. That ship sailed long ago as far as Cat are concerned, there are no freebies. The only possibility I can think of is for someone to recognize what brand of drive motor it is from a photo.
Bugger.
Yep. They don't make it easy.
Thanks Nige and Tones Find some more info final was made by Transmital-KYB, maybe other brand got rights to sell parts from gearbox side so cat didn't show those parts Kubota distributor have those on stock
Usually they aren't generic to one brand of digger so other Japanese brands could be using them also. There are independent dealers who specialise in this stuff.
