Hi all,
I had a service man come to my business a few months ago to replace some brushes in one of my drive motors because they were stuck..
Well, it seems like the other motor has stuck brushes now too. The last service call was a surprising $800.. I am trying to work on the forklift myself now. I got two of them moving again but I am having a heck of a time getting to the other two.. Any thoughts on how to get to them??
Thank you,

Chevo,
I felt the motor was a good price so I jumped on it..
I tried draining the drive unit oil but the allen screw is rusted in to the point of stripping.. I think I am going to have to try an easy-out...
I also ordered a service manual for the machine...

RC3000 Drive Motors are about $1276 (new) and $950 (certified crown renew) direct from crown with warranty. If you are actually getting a new Crown motor for that price, you are getting a pretty good deal!
As far as your drive unit checks.
-Draining and inspecting the gear oil will tell you a lot.
-Drive unit noise (Grinding/popping sound)
-Slop in the final
Its just a gear reducer (a box with gears, shafts, seals, gaskets and bearings)
Thank you for your responses.. I was able to get to the brushes free, 3 of the four..
Then today I had had to roll over a small concrete lip 1" high (empty forks) and i thought going slow would help.. After about 5-10 seconds of trying i backed up and it sounded like i was playing with a bag of rocks... I immediately parked the forklift, lifted the front end by using blocks under the mast. turned the steering wheel so only one drive motor would work. I let the motor run for about 30-45 seconds so i could get a read with my stethoscope, in hopes to isolate where the sound was coming from. I had to stop because the motor started to smoke like crazy...
I am confident that i burned up my motor enough that I bought a brand new one , crown brand , from ebay for $825 delivered. arrives this coming week..... not bad considering today's insult.
But could the drive unit be toast as well? How could I test this? I have removed the drive motor... Are there instructions or drawings etc available?
thank

Bottom drive motor brushes on RC's are very dangerous if you do not know proper blocking procedures. If you are not trained on blocking procedure I suggest pulling the motor and rolling it to get to bottom brush. This does add a lot of labor/time but... A lift truck falling on a human body is almost always deadly.
You can move the battery to get the one on the back side there is a slot and the bottom is you just have to feel by hand.
