my 1967 patina project build

I just noticed the pic of your super swampers...!

Coolest

Tires

Ever.

But Noisy.... Noise----EEEEEEE.

If you enjoy pretending that you're the pilot of a B17 as you roll down the road, you are gonna LOVE those tires. But off-road, they are like tank-tracks.

I beg to differ. I think the N78, P78, and Q78 Gateway Buckshot Mudders are the best ever! But I am biased, because they were supposidly developed right here in Mississippi for the delta farmers,,,and since the molds were sold off by Gateway a few years back, and Gateway bought had few sets imported back in a few years ago, I bought a set of P78s.

Well the tread patterns are so similar, that I guess it all comes down to who has the cooler name for their tire:

"Super Swamper" vs. "Buckshot Mudder"


Hmmm... It may just be a tie.

I looked at getting a set of the buckshot mudders but the price was close to $1000 so I went with the super swampers. I also looked at the Original Swamper from 1968 that they offer also but it is a special order only and I am sure that is represented in the price. Not sure which was first but they do look very similar.

Today I had a little time to get the rings on the pistons and the pistons installed. I checked the ring grooves on the pistons and found one to have a small nick that caused a tight spot so U used my ring groove tool to clean it up.


The pistons have a F on the side near the wrist pin that signifies front. The rod caps have match numbers on them that will be facing the cam side of the engine.


The compression rings usually have a mark that identifies which side is the top. At first I did not think these rings had that mark but I finally noticed the little 100 size on them. only the 1st and 2nd compression rings have that mark. The oil ring has two thin scraper rings that go one each side of the oil ring.






Then I used my ring compressor and then tapped the pistons in with the wood handle of a hammer.


And then torqued the rod cap nuts.

The "Nissan Engine Model P Service Manual" was a little light on detail so I purchased a "TCM Shop Manual" for the PPU240 engine. It provided a little better info. I have scanned and attached a few pages from that manual below.

Excellent details of the process. Textbook quality. Thanks!

The pictures are great as always, and the added bonus of the scanned manual, even better.

Thanks for great documentation!
I pushed the “Thanks” icon, but received back a message “invalid thanks”. What can this mean?
I felt like a kid who has just been told his apology was not sincere enough.

Not sure why that would happen, maybe the system was busy.maybe River knows?

Sometimes the 'Thanks' button has a mind of it's own. Rest assured, we consider your thanks sincere.

This A.I. stuff is getting rather sophisticated. I may have inadvertently selected the icon by using my middle finger, so sarcasm was possibly implied? I’ll be more careful next time.
