Para-Rail Repair

That was fun, but do not need to do it again for a while. Wound up with 14 pounds on the spring, I like 11, but will try it as is.

I am using the later style chain case, and driven pulley. Installed a temporary chain case on the chassis just to hold it all together while sand blasting and painting.

Turns out, I like the look, so I left it.

Grill,s are marginal, one is missing chrome, so I painted it. The other is missing the cross bars, so I am looking for a chrome wire shopping cart.



The drive shaft and drivers were very nice, as the donor sled only had 1400 miles on it.

I like to slather the wheel with epoxy, and add a clamp. Would be nice to find better clamps. Thought about those galvanized clamps as used on a chain link fence, but that would be just to much bulky hardware down there.

Some of my pics post full size, and others appear as a thumb nail? I love computers!

Track, drivers, and suspension go in today.

The old Super had 20/40 sprockets. I was going to use them, but the old bottom sprockets do not fit as the splines are cut at a V shape Later Scorpion used the same size and number of splines but they were cut more square. You can file the old sprockets to fit if so inclined.

Also had to weld in the para-rail shock mount.

I can not figure out why some pics become uploaded as thumb nails, and the others way to big?

Ok, got side tracked, and slid the ol Super out of the way for now. I was digging around through one of my parts stash sheds, kind of reorganizing, and wound up dragging home a pile of Sachs singles.

This old 290ss really caught my eye, and I just had to take it apart to "check it's condition"? Ya, that is code for "build race engine"

The crank was good, gave it the chisel in one spot, and it came within .001 on both sides. Fukin a skippy, lets grind her out, and build a pipe!

This engine is not worthy of a Super Stinger, but good enough for an old Lynx, or Puma.

Still side tracked, got to messing around with a JLO 400 4 bolt out of a 73 Super Stinger TK. It had the usual burnt piston on the clutch side. I melted the aluminum out with muratic acid, and it cleaned up nice, except the darn thing was also rusty, so it needs a new bore.

I did find another cylinder, but am hurting for a standard size SPI pee stone.

Again while digging for spares, I come across a pair of really nice freshly bored 440 6 bolt cylinders with pistons to fit. So I guess I am building another motor, out of parts.

We did finally get an inch or two last week, and another 1 1/2 today. The neighbors went crazy with big snow blowers, and 4 wheelers with plows. When they were all done, I ran up and down my driveway with a push broom, took about 10 minutes. I do not know what is wrong with those guy's, well actually, I do, but being careful not to be political.

So I was able to test the TX donor sled, 9 degrees, it needed stabil sprayed into the carbs in order to start, and then needed a few more squirts to keep it running for a minute. I suppose it needs pistons and rings. once it is warmed up, it starts easy, kind of like all my half worn out vintage sleds.

Now I am massively side tracked as ice racing starts in 3 weeks and I decided to campaign the old Red Racer. This thing has been pickled for the last 3 years, while I was dinging around with a Yamaha Exciter in the D stock class, of which I may not run this year, just kind of lost interest for now. It is a great sled, and a great class to run, but I found it to be way simpler to just run 1 or 2 sleds on race day. So the Yami might have to sit out this season.

Remember the 6 bolt cylinders I found at Princeton, I could not resist, they are going onto the old 4 bolt Red Racer sled. I will temporarily retire the 4 bolt top end for now, but that set up was legendary.

I am using the same exhaust, clutch, and carb. The only change is the top end, so we will see if the 6 bolters are actually any better.

Now if I were to plug this new set up into a Sting pipe, I am sure it would be faster, but I have to run the Donaldson in this E Stock class.

So the TK 400 engine rebuild is 50% complete, all boxed up, and set aside. The 6 bolt conversion is my focus this week.

Today, I am fabricating an exhaust manifold to fit the Double Donaldson muffler, should take all day, and several Heinkins. I have to go to my brothers shop to braze the pipes, and he will get me messed up for sure, probably will have to crash there.

I will use this plate cut free from an old manifold, this way the cylinders are all tied together, no flex.

The little one in the picture was built by Charlie, and is probably ok, but it is a tad small, so I am going to build my own version, this way I get to go see my brother

That exhaust/cylinder plate is a great idea!...I guess that beer works!!!!!!!!!!!!!

Say hi to bro for me.
