Re: P60 planetaries gearboxes

Everyone,

Thanks for the interest in the P60s.

Given that these are a new product being used by a good number of FIRST teams, we thought it might be good for us to monitor this thread and provide answers to questions that may come up. We would like to give credit to the person who called and suggested we do this, but honestly we forgot to get his name.

Please ask any questions you have concerning the P60s and we will respond to them as fast as we can. Please understand that we do not continually monitor this forum so it may take a little time for us to post a response.

It seems the largest question right now is around delivery time. We have been working 7x24 to meet the demand for the P60s

All orders for P60s placed before 1:00PM Mtn time yesterday (Jan 27th) have shipped.
Orders placed yesterday afternoon or today will likely be shipped on Thursday or Friday.
Orders placed Wednesday – Friday will likely ship next Monday.
Starting next week we hope to maintain about 2 days from order to ship.

We do not anticipate any problems or delays due to materials, all lead times are a direct result or machining and assembly times.

A few things to note:

- The screws on the 64:1 are a bit short. They engage enough to hold but longer would be better. We have not been able to find an affordable source for the 2-1/8 inch long screws so we had to go with the current 2 inch screws. If you are worried, you can pick up some 2-1/4 inch screws and cut them to length.

- The grease used is not critical. We use Mobil XHP 222 Special, it is readily available from many sources includnig McMaster, Grainger, and MSC. Some people have chosen to get the gearboxes with no grease and use a light oil (you might be surprised how much resistance the grease adds.) We can't directly recommend this but have found that it works OK for intermittent use. Keep in mind that you can (or will soon be able to) purchase the gears separately if you push it too far

- When assembling the gearbox, ensure that all 4 spring pins are in place in the front block. They keep the ringgear from spinning. Only two engage at a time depending the the direction. If one is missing in a high stress application, the other may push out and allow the ringgear to spin.

- The blocks on some of the geasrboxes are a bit tighter than we planned, we have adjusted to correct for it. There is nothing holding the gearbox together besides the 4 long screws. If you are having trouble separating the blocks and the ringgear after removing the screws, you can gently tap the blocks to remove them.


Please post comments, questions, and suggestions. We appreciate candid feedback and will try and respond in a timely manner.
