I'm on the learning curve with my 2 Lehman 120s in recently purchased GB42. I know about Racor filters, fuel lift pumps and how to change oil/filters in my engines. I also got copy of Operation Manual from the GB Forum site. I wanted to attend next month's Lehman workshop in Lake Park but class is full. So, here are a few questions (4) that I have:
1. Frequency for changing transmission oil?
2. Is it important to have temp sensor or gauge for transmission?
3. Is it crucial to check torque of head bolts every 400 hrs for normally aspirated Lehmans or just turbo charged?
4. My next maintenance step is changing oil in Simms injector pump reservoir. I've already seen some great posts on this. I understand where the drain plug is, where the "fill level" plug is on right side facing sump, but is the actual "fill plug" on top, the very first plug forward of injector lines? Mine is circular with a slothead. Just after is another plug-looking with a white cylindrical extended plastic cap with a tip projection.
