I have a Bally Reliance, and it is my appreciation that the mechanisms are on the Reliance and the Bones are similar, except for the payout (2-4 on the Reliance). The "Bones" is the rarer of the two, and brings more on the market because of that. See Buschel, An Illustrated Guide to the 100 most collectible slot machines.
The old grease and oil can be cleaned with lacquer thinner. Contrary to what most people think, it is not good to drown a slot mechanism with oil and greese. Certainly, the coin slot does not need oil in it under any circumstances, nor do the nickels, nor do the dice. If you are using brand new nickels, they are slightly thicker than the older nickels and that could be your problem on the larger payout.
Rest assured that the spring has some purpose. It may be part of your problem with the smaller payout. See Loose Change - April 1978 for an article on the Bally Reliance with some pictures of the mechanism. This may indicate to you where the spring should be attached.
The expert on these machines is Jeff Frahm (Two - Bit Restorations), 4750 W. Mint Creek Rd., Prescott, AZ 86305. He is listed in the C.O.C.A. directory and advertises in the C.O.C.A. Times. He did a magnificent restoration job on my mechanism at a reasonable price. You have a very valuable machine, and it would be a good investment to have it placed in top notch condition.
I hope that this information is of some assistance to you.
