Bond Bug ZZR1400 Project |
Alternator upgrade- in progress
Currently with a specialist company making the new outrigger bearing, custom pully and belt system.
The new Kawasaki ZZR 1400 engine has an internal alternator outputting only 38 amps in a counter clockwise direction. No upgrading to the existing windings is possible.
I am going to drive a new CCW 170amp Delco Remy high output alternator by extending the existing crankshaft through a bearing housing. The existing rotor and windings have been removed.
A specialist engineering company is building the new shaft extension , bearing housing, two new pulls at a 1 to 0.9 ratio and the engine mounting plate with adjuster. A serpentine belt will be used to transfer the power.
The downsize in the pully ratio is to allow the 12,000 rpm engine to drive the alternator that has a max rev of 10,000 prm.
The new alternator is brush less and provides 100 amp at idle. More than enough to power all the ancillaries.
New alternator finally finished - aluminium items sent off to be black anodised this week
