I got the new to me LK unloaded today (model & serial numbers in post # 61 above) I pulled all the cooling shrouding off, blew out the old dirt and opened the control box. The start relay (307-1048) is missing. I happen to have a 2.7AJ, would the start relay work so I would be able to see if the 2.5LK unit will start or will I have to get the correct relay?
The RV parts manual lists the 2.7AJ as a start solenoid (307-0845). Since I don't have one to match it up to I have no way to tell.

Thanks!

The manuals should be in your mailbox.

I would not worry about the smoking until you have run it for an hour or two at near full load. The rings may be stuck from sitting for a long time. The compression specs are 100 to 110PSI. Again, after you run it for a while it will probably come up to about 110PSI.

If it has the original metal clad head gasket you can reuse the gasket. I always pull the head, pull the valves, and clean out all the carbon. If there is sludge in the oil pan, you can try rinsing it out with kerosene (NOT running). If that doesn't work, I always pull the oil pan and clean it. No sense in putting clean oil into a pan covered with sludge.

thank you for the manuals I pulled the head and cleaned the small amount of carbon off the piston and head .I then took a hone to the cylinder and put it back together. the engine started with almost no smoke . I ran it for almost 1 hr with a 1770 watt load I am very happy with results.117 volts 60.2 hz the one thing I noticed is the lk runs a little less smooth than my aj's is this because its 1800 rpm not 3600 rpm like the aj's THANKS AGAIN FOR YOUR INPUT

I just aquired two Onan 2.5 LK-1R/10545J generators. The serial numbers are 0774811062 and 0572443381 I got one running but it smoked and knocked (sounded like a wrist pin) really bad. It was however making power. The second one I was told, had power output problem's but the engine was supposed to run. Hopefully it will with no loud noise's so I can make one good one out of the two. I need some manuals so I can work on them. I would be so grateful to get the service,parts and any other manuals available for these generators from someone. My email is msdb56@outlook.com if anyone can help. Thank you, Daniellehttp://www.smokstak.com/forum/images/smilies/redface.gif

Take look at post #74 for a link to the LK manuals. You can do a search for "LK" and you should come up with manuals you need. Just look for your spec.
