Lister HR4
« on: April 12, 2016, 11:28:18 PM »
Hi everyone. I have a Lister HR4 gen set. The alternator is a Kato 18KW, 60 HZ @ 1200 RPM. Engine runs fine but the RPM is not consistent, which causes under frequency when engine is cold, then can go over frequency when engine warms up. When light load is applied, frequency is from 59 to 61, put some load on her and she will shut down on under frequency. I think maybe the mechanical governor is not working, her RPM should be constant whether engine is hot or cold?? She has the Cav Minimec inline pump. I think it is a 5222 model. She has the throttle arm in a fixed position secured with a bolt in a slotted attachment.   Anyone have any thoughts? derektwakefield@gmail.com  Thanks.
