AP900 informations

Hi everybody,
I just became the owner of an AP900GTO of 1999 fitted with CP3 V1 chip and a Keypad. What is the procedure to perform a re-greasing of the motor box because the grease seems to be old (there is dried deposit)? Is-it also necessary to check and re-greasing the RA and DEC axis, is there a procedure to do this? Is there a list of possible upgrade of the AP900GTO version to the latest one (CP3 to CP4, V1 to V2, new motor box...)? Thanks for your feedback, Julien. |

Julien, You can upgrade the control box itself or at a minimum upgrade the CP3 to the V2 chip, which will enable you to use the latest drivers. The chip upgrade is not difficult if you are familiar with changing socketed chips. Steve On Mon, Apr 4, 2022 at 10:51 AM Julien LECUYER <lecuyerj@...> wrote: Hi everybody, --

No need to re-grease the axis - don't try to take the axes apart. You can regrease the worm gears by removing the motor boxes. See the website for instructions.

I think the V2 & V1 chips are for programming instructions that can be understood by encoder equipped mounts like the 1100, 1600 & 3600 mounts, which was not part of the V chip.
For the 900 <and 1200> mounts- which are "not upgradeable to encoders", the V1 or V2 chips won't impact performance- I believe. So upgrading the CP3 from V1 to V2 for the 900 mount shouldn't be noticeable. Fernando |

Hello,
Thanks for your feedback. According to the message of this forum about grease, I have buy the Aeroshell 33 one which have the correct green color. Nevertheless, on the constituent, I see that this last one contains "dialkyl sulfide (CAS 822-27-5, 0,1-0,9%)". Is this grease is correct? Regards, Julien. |

You do NOT the formulation that has sulfur. FYI. As alternatete, A-P carries their own formulation. Bryan |

Any grease that contains sulfur will be bad for brass and bronze gears. Aeroshell 33MS contains sulfur, so avoid that one. Plain Aeroshell 33 is ok to use.

Hello,
I have bough Aeroshell 33 not Aeroshell 33 MS. Aerosheel 33 MS (now renamed as Aerosheel 64 due to possible customer confusion) contains 5% molybdenum disulphide (color black) and Aerosheel 33 contains dialkyl sulfide (color green). Thus, it is not possible to use Aerosheel 33. Is there any other existing grease to do the job or does anybody have a picture of the constituent of the right Aerosheel 33 in order to see if it the same than mine? Thanks, Julien. |
