Otter LRC CM4647296 comes home

I’ve referred to the below website previously.

The part on the Zener diode is near the bottom of the above link. I’ve included the relevant section as an image.

It’s full of very well thought out modifications to inline 6 engines. However a lot of what they write about can be applied to any make of our vintage vehicles.

As a follow up, I emailed the guy who created the above website asking if a heat sink was required. His reply is as follows.

As for my setup, I thought about adding heat shrink, however the diode is mounted to the fibre board then kept inside that housing.

Nice work as usual, Jordan. I like how you did the small pressing....small modelling jobs on a big vehicle.

Bob, I bought 10 online with shipping for about $20 Cnd. One was bad or I fried it on my variable DC power supply. The rest were fine. Compared to the other options, I find these are a great deal with very little to go wrong. The Runtz ones have more components and require a dedicated ground. Basically more things to go bad.

Alex, the time spent on making the stamping die was substantially longer than pressing the one successful piece. By that point it was simply more of the challenge to see if I could stamp out a part like this.

Pulled the engine the other night. She is one heavy power plant with the bell housing and transmission all attached. I’ve still got to build a simple wooden cart to hold this engine so it can easily be moved around the shop. Once that is done, the plan will be to pull the transmission and get it taken apart and rebuilt.

The oil filter was also removed from the frame rail. I took advantage of the warmer weather and got it all cleaned up and painted. When I was cleaning the grime off, I realized the filter had been over sprayed with KG#3. But only the side that was visible and not covered by the frame. When I removed the mounting brackets they were the proper gloss black and the filter was the early grey colour. For now the filter will stay grey. But once it’s back on the frame I plan on giving it the same overspray of KG#3

Lastly I’ve started removing the floor panels. Lots of sand, rust and other debris is coming out of the Otter. It’s amazing just how much crud has accumulated in this vehicle.
