ST3 Rebuild
« on: January 16, 2012, 05:16:22 AM »
Its been a while sense I've been here. I bought a used ST3 Gen Set about 3 years ago and its looking like I need to do an over hall on it. I went to change the oil and there was metal suspended in the oil. It wasn't running smooth either. I'm thinking it is a valve/piston problem because one cylinder didn't seem to have good compression.

I'm thinking of taking the top end apart first. I have a manual but is there anything I should be aware of? Does anybody know a good machinist in the Sacramento or Reno areas? What kind of Money am I looking at for a good rebuild? Parts and machine work. I'm figuring I can do the tare down, cleaning and assembly.

Thanks for any help and pointers....

We rebuild a lot of these... 40 hours + for the labor and typically about $2500 to $3000 for a complete overhaul set to bring everything to factory specs. Machining will be minimal in this model, everything that suffers significant wear and tear is replaced. On a 3 cylinder it is common to see them run long after a fairly drastic failure of one cylinder and this most likely explains your metallic contaminated oil.

We build them on a steel topped table with an overhead hoist to handle lifting and moving... I have not seen any engine stand used for this style Lister before. That could be an interesting thing to research!

That made me go and have a look! I am figuring I can mount it using the generator fan shroud mounting holes. My gen set is mounted on a trailer frame so I might just leave it on that and put the whole thing on some stands so it is at a comfortable work hight.

Guess I should move it into the shop and just get into it....
