Since the motor is broken and a replacement is very pricey, I’m investigating switching to a new motor, controller etc.
The first question I’m running into is whether I still need the Peerless transaxle transmission model 180B118. I think it’s a Peerless 800 Series. Here’s an exploded Transmission diagram and part list that I received from palmer. Peerless
From my limited understanding, there’s not much need for a transmission with modern motor systems. that said, it’s not necessarily a liability. It is added weight and there’s probably a little power loss running it through the transmission.
For the technically-minded bidder, the Forward-shift gear ratios are: 1st) 4.55:1; 2nd) 1.50:1; 3rd) 1:00:1; 4th) 0.79:1; and 5th) 0.61:1. Input pinion ratio is 2.54:1, final-drive/differential ratio is 8.02:1, and Reverse is 2.00:1. Other gear ratios are available for this transaxle — I can change ratios or convert this to a close-ratio transaxle, if you need it.
The last resource I’ve found on the Peerless transmission is a manual. Here’s the transmission manual.
