darn impressive and logical custom welding project


I've searched every possible keyword and I can't find the splined shaft. Without that not sure what you could do. Any ideas how to get the shaft???

 
I thought you made the custom one off Heavy Duty engine stand Grumpy.
You do need to make a few similar.
Be decent project to complete in a few days & earn extra $$ on the sale.
Bad economy here too.
Know they will sell.

The splined shaft is the "S" CAM from a large air brake diesel truck with Drum brakes.
Front drum steer axle or Rear Daul tire axle.
Kenworth. Peterbuilt. Volvo. Mack trucks. ect.

Any diesel shop has a scrap iron pile.
Find used worn out S cams there.
Worth maybe .50 cent scrap iron price.
The slack adjuster has to match S cam aplication.
Some Slack adjusters are self adjusting. Others not.
Have to investigate more myself.
My boss Jack is the large diesel air brake expert.
So many variations used from 1960-present.
I see & work on them all.
In farmer land.
Ethanol plants all around.
Full sized Kenworth or Peterbuilt with a Caterpiller engine the favorite road machine to haul their corn & make moonshine.
I fix pickups & Cars in same shop. Big shop.
 
S cams can be found on all 52 foot semi trailers too.
All have drum brakes air powered brake chambers..
Slack Adjusters.
My new 4 Leg wide base engine stand is a POS compared to the home built geared slack. adjuster engine stand.
Just ingenous.

Profesional geared stands cost $800- 4500 bucks.
 
Id bet almost anyone with minimum welding and fabrication skills and a few tools like a decent welder could build a better engine stand , or modify an existing stand to be far more user friendly with just a few hours work and some proper planing.
EXAMPLE

about 8 years ago, I added 4 decent quality caster wheels to each of my engine stands in the shop, effectively doubling the cost of the stands but making them far FAR more user friendly, because they roll far easier, and you can lock the wheels when working on the engine making torquing the bolts far safer and easier

these are very similar to what I used (6) of on the engine crane, having 6 large diam. CASTERS rather than 4 small casters and two wheels that don,t change direction is a HUGE IMPROVEMENT in how easily the engine crane moves once an engines suspended from it
I use this style mostly for storage, once you add the larger casters its a decent functional engine stand

I have one of these stands, I modified with the larger casters and additional diagonal braces, that I use for most engine builds because its very stable, and a decent bargain for a cheap stand but I would add the engine turning mod in a heart beat if I had the parts required

Yes. I am going to add heavy duty ball bearing Rubber tire caster wheels to my new 1250# engine stand.
Love the Truck drum brake slack adjuster idea.
Radius ring machined & welded to pivot neck tube.
Mine will be different to use with engines & my vintage Kent Moore RWD Turbo 400- 700R4 Trans support & Kent Moore Corvette Dana 44&36 diff holder & another Kent Moore Vintage 1957-64 I-Pontiac 9.300" 3Rd member center section holder. Ebay finds .. ;)
 
This is not overengineered, this is a example of a great mind at work. Is is possible to turn the engine using a air ratchet? Seems it would make it a lot easier since we old hotrodders aren't getting any younger.
 
now that Im forced to buy/build a new engine stand this info will be helpful






one more in a nearly endless list of reasons every serious engine builder needs a decent welder

does anyone know where you can purchase just the engine stand, mounting, and rotational head assembly for an engine stand at a reasonably low price, as Id love to custom fabricate my own engine stand device,
with a manual engine rotation adapter, and several other upgrades. modifying an existing stand is obviously an option, but Id be wasting a good deal of cash and paying for parts Id throw away, that would be seriously upgraded
like a roller bearing rotational head, larger casters with brakes, and a gear drive rotation on the engine, maybe even an angle adjustment on the block if weights making it droop a bit
, a larger more stable base helps
a quick detach mount head for use on transmissions would not hurt either

this guy in the video above has got some reasonably good ideas and several really bad ones

Is this what you are looking for, it's called a "Slack Adjuster" ?
It's used on air brakes for large trucks.

This guy had some good ideas also, below is his second video for mounting the head and brake.

what Im looking for, to purchase (reluctantly) is, the upper engine holding parts painted black on this picture
I know I can easily design a better engine mount plate and rotational head assembly

The main plate could be made by sending a dxf file to "Send-Cut-Send" and made from 3/8" mild steel for $52 for a single unit or $42 per unit for two. I used FreeCad to make the drawing. I think shipping is free.

Dimensions For Quote Above Would BE .......

Need to make changes ?????
