Rayco rg25hd gear box ..

Recommended Posts

So my RG25HD has had a new input shaft kit and a rotor ball kit due to loosing drive. When it went back into the machine, you push the lever forward it now goes backwards instead of forwards and when you pull it back it now goes forward.. it's then turned off and the person that fitted the parts and rebuilt the box had a play with the adjuster on lever down behind the left hand wheel and she would only fly backwards as soon as you started it up so turned it off immediately and he then leaves! This morning it's now not doing anything forward/reverse?


Any ideas.. is there something inside the gearbox that he could have put back together wrong changing the way the oil flows? Why has it gone from working incorrectly to not at all.. Clueless.


A new handbrake cable was also fitted and is completely useless as when applied the right wheel doesn't lock up. :thumbdown:

Have you had a look inside the control lever? There's a degree of adjustment there as well. Mine had a really weak forward drive but reversed like a champ and got the adjustment I needed there

No drive whatsoever is likely to be the drive belt from the engine to the Hydrostatic gearbox either broken or too loose or the tensioner broken. Also check that the Hydrostatic disengagement lever is not stuck, or the button it pushes onto is not stuck in (this can be seen from above on the rear of the Hydrostatic gearbox).

I'm not sure how the drive lever can have been reversed though?

However' if the linkage has been changed, then the ground travel control lever needs to be adjusted to neutral so that the wheels and hub stop when the lever is central.

Without looking at it, I can only assume something has been fitted 'back-to-front' to cause the change in lever direction?

It does sound like your engineer is pretty useless though!

Call Westcon Equipment and ask for Malcolm in the spares department. He is a font of knowledge and will probably be able to help. He will also be able to supply you with a Operation, Maintenance & Parts Manual which will help you to understand and be able to fix your machine yourself. I believe that to be able to run a stump grinder efficiently, you really need to be able to maintain and repair it yourself. Having an affinity with your machine, promotes mechanical sympathy, which in turn creates harmony between man and machine and will ultimately keep your costs down.

Had it apart tonight and the new rotor ball wasn't machined properly not allowing one ball bearing to move at all so no wonder the machine didn't know what way to go, handbrakes spot on also after sanding the rough edge off, just what you expect £300 parts.


She runs happy days.

I thought the same with the change in direction on the lever but there's only one way things can go back together, there wasn't much to it really I do all the servicing sharpening etc but never opened a gear box.. luckily he returned tonight and there was no extra charge from original quote to repair machine, wasn't his fault in the end.
