Gordo's X8 Ramblings

Recommended Posts

Finally put all the finishing touches on the adaptor plate, like assembly access holes, throw-out lug, and throw-out support.

Not going with the Quartermaster throw-out shown, as I had a Coleman that the bleed hole was at the top, that I liked better.

Off to the welder soon, then the helicoils can be installed, and ready for the final trans assembly.

 

I also swapped barrels on my wheels, so that the 9" rears had gold centers, instead of the silver they came with.

That means I can finally mount rubber :)

OK, as many of you know many of the simple little parts are no longer available from Toyota.

 

One of these is the small press in bronze bushing that goes in the block, to support the top end of the oil pump shaft.
Toyota p/n 11437-45010.
After 25 years of getting fed unfiltered oil directly from the pump, these are typically worn, as is the shaft end.
When this bushing & shaft gets worn, more pressure is applied to the bushing in the pump. just below the gear, and when that gets sloppy, the gears move away from each other, and start wearing.

 

Thankfully, there are a few pumps floating around still, but no bushings.

 

Now is some of you remember, I got on the parasitic drag quest a few years ago.
One of the things I made was a needle bearing replacement for that bushing.

But I never put this in, as I had 2 issues with the idea.
1) That was a very small bearing, to fit the 7M's 8mm shaft.
2) The 7M shaft is not hard.
That made me realize that this idea was not the best solution.

 

So I used my last new OEM bushing when I built this latest engine.
I even moly coated the bore.
But it still bugged me that there wasn't a better way.

 

After who knows how much coffee (no drugs mind you), I came across a better way to use a needle bearing in this location.

Found a closed end bearing, with the same OD as the hole in the block (16mm).
It has a 12mm ID.

Located a hardened steel precision ground bushing that has the required 8mm ID, and 12mm OD.
The through hole in the pump shaft was small enough to drill & tap a M5x.8mm thread in it.

 

Then had the problem of how to get oil to the bearing.
Came across 'vented' cap screws while searching for something else, but none of them were long enough.
So figured what the hell, lets see if I can drill a 1.5mm hole through a damn black oxide M5 FHCS.
I can either do it, or the frigging little drill will snap, get stuck in the hole, and end up costing me $1.50, and a little time.

 

Well, it worked :)
One drill is good for one 25mm long cap screw, and it takes a lot of time, and caution to not screw things up, but it turned out good.

 

All it then took was running a 4.2mm drill into the pump shaft to get the correct hole diameter, and tapping it.

 

This I'm happy with.

Drilling a little bitty hole through 25mm long cap screw.
Note the copper between the chuck jaws, and the screw to keep from damaging the threads.
Did the same on the pump shaft.

Tapping the pump shaft, after drilling it 4.2mm (only about a .5mm increase)
DSC09165.jpg

 

The bearing is a BK1210.
Bushing is an un-shouldered metric drill bushing, 8mm ID, 12mm OD, and 16mm long.
Had to grind a 45 degree seat for the cap screw to sit in.
And the screw is an M5 x .8 x 25mm long FHCS.
Total cost (not including 25 pounds of instant coffee, or machine work, or shipping) is less then $25.

Well, don't hold your breath.

Wild ass ideas are coming fewer, and farther between.

May be due to the drugs I did back in the '70s are finally wearing off.

Well, redoing my 044 pump set up again.
Ordered in one of the Holley HydraMats. Went with a 15" by 8" cross units.

Since they come with good old 'merican pipe threads, couldn't directly attach to the bottom of the pump,
so more fittings, and now hoses.
Cutting the old pressure out line off, and going with a -6 bulk head fitting.
Not all of the fittings are here yet, but I will post more pictures when they do show up.

On another note, any circuit type events now require a Hans device. Fuck they are expensive... Sad
Found an old used on eBay for $150, so grabbed it...  Happy
Then Rue ruined my day by asking what the certification date was... Sad
Asked the seller, he said it didn't have one, so I asked to cancel the sale... really Sad
Next day I called Hans/Simpson, how just happen to be just 15 miles from me, to ask if they could recertify an old Hans.
They said no problem, just $25 plus cost of new straps... Happy again!

Took it to them yesterday, walked in, saying I had a Hans that needed recertification.
Gal said no, that wasn't even their product... Sad, and a little pissed.
We argued for about 5 minutes about how there was a picture of this unit on the Pegasus web site on the history of Hans.
I'm getting more sad, and more pissed.
She gave in, took the unit to the offices, and came back without it.

I'm already thinking of how to word the description for an eBay listing, so I can recoup some of my $$.
15 minutes later, Tina from the offices comes back with my $150 special, and explains to me why it can't be recertified.
I'm thinking more about dumping it on eBay as a relic, or collectable, or vintage Hans unit (and how cute Tina is).
The reason is that it's a first production unit, and there were no certifications on them back then.
So I say something to the effect of it being a wall decoration, and she says.....

"Would you like to trade for a new one?"

About the only thing that could have been better is if she asked me if I wanted to go get naked in a motel room !
But a trade for a new one would do just fine, thank you very much !
Turns out they wanted it for display, and they had only seen one other of the first production units.

I drove home happy, and with a hard-on.......

Any one have a really old Simpson helmet, so I can go talk to Tina again ?

my simpson is a M1995 unit, my new one is a M2010.  do those old ones get recerted? i really like my old one better than the new one. new one is a bit stiff in the cheek.  both my helmets use the same visors with different hardware, interesting how they chanegd and didnt change. i think in 2015 they started a new design and phased out all the old stuff. i dont really like the new stuff with their weird ribbing on the top.

You would have to contact them.
I know belts can be, but never checked into helmets.

OK, Change of plans # 21,426.....

Sold my reclinable Recaro seats before ever installing them.
Decided to buy them due to long trips sitting in my old Momo T-frames making my butt hurt.
Then realized that seats to hold my skinny ass in place was more important than comfort.
If I wanted comfort, I would have kept the stock seats.

So now looking at the following: Bride Zeda-III, Charge Speed Spirtz SS, OMP WRX-R, or Sparco Pro 2000.
Like the OMP Airtex fabric, and removable side pad to adjust for hip width, but only available in black.
Like the Bride, and there are lots of aftermarket things like vinyl edge protection pieces, just don't like their blue, as they are only available in the 'logo' fabric. 
The Sparco look to be very comfortable, and they have all of the upholstery replacements, just they have that crappy wimpy material typically found on stuffed animals, and don't really have high side bolsters.
Charge Speed are a little sketchy about how wide they are, have no replacement cushions, but for the same $$ as the others for 'glass, they are carbon fiber.

I'll just cut my Bride bases apart, and adapt them to take non-adjustable side mounts.

Brides are very tight in the shoulders and skinny in the hips as a heads up. Do u have access to sit in any of these?

Out of those I'd say the OMP is what I'd go with. But for my next project I've been eyeing the Veilside reclinable buckets in carbon. They are't too expensive, look like a comfortable shape/size, and I've never seen anyone use them on their build.

About the only ones I could possibly sit in is the OMP or Sparco, if I drove to Austin (Winding Road Racing), if they actually have any in stock.

I'll try to call them this week.

The omp and sparcos I've sat in are quite large for me. I'm 6'3 and mostly leg, slender frame, 200ish lbs now a days and broad shouldered. My spgs fit me the best. Ppl forget everyone is shaped different so when they talk about height and weight it doesn't really matter much due to where the weight and height is located

I wanted a pair of SPG Type-  2, but none are to be found, and used when one pops up, they go for $1500 each.
Even then, when they do pop up, they have the yellow center pads.
Probably going with the Zeta, as I'm only 150 with my boots on.
(nothing else, just my boots, that's how I run around the neighborhood late at night)

Sounds like your sized correct then for the bride's. Old balls and all. Lots of bride's for sale. I still think the srds, if not in terrible shape, are a great all around seat for comfort and staying put

I love my Bride Zeta-III Japan. I have the regular size. I'm 5'-11", 165lbs. 32 waist, sorta broad shoulders. I fit perfectly in it. Hardly able to wedge my hand between my thigh and the bolster.
I do daily drive with this seat and I find it comfortable. The only time I feel discomfort is when it is hot and there is no air flow to my back. Sweaty.
I think the Large size would be perfect for daily driving comfort as it would give me that little extra wiggle room. For track days, I wouldn't want any other seat to be honest.

I have heard many Americans love the Bride L and XL sizes. I think you would definitely be able to find comfort in the L seat. I have heard Recaro hip sizes run narrow.

quite the opposite. my recaros have good waist sizing then widens out for leg and balls, all brides new and old ive sat in, all legit ones, are tight in the waist and dont widen much, so my balls have zero room, as well as the shoulders pushing in. the newer ones got better, but i still like the recaro for my body size

I wish there were local places that had major brand racing seats on display that a consumer can try out before dropping $800-1500 on a seat that may or may not be the appropriate size. lol
