Colt Case Ingersoll Garden Tractors

Sometimes the little guy just gets a break. Called Hercules, turns out it's just a glitch in the online ordering system, anyone can buy with a credit card, but now it only allows businesses with PO. Until it gets fixed one can place order over the phone. Yay!

Now I'm fighting the bucket cylinder which has the retaining ring all broken inside, rusty and apparently impossible to get out. If I do them I may as well do them all. Once I get the parts and confirm proper fit I will post all the parts numbers needed to redo all the cylinders.

This was a nasty one.

That looks like a whole lotta fun right there. Is that the reason for the weird rants last night

That's it Tim!

Eugen, have you ordered seals. I would have ordered for you as we have an account.

I think 90 durometer would be fine. 70 durometer would likely give you 20 years of service, 90, a little more. Then you get the joy of taking them apart again. Never used 95 urethane.

Thank you, but I don't want to trouble you with this. I am still working on making sure I'm ordering the right parts. Measuring things again and again.

On the subject of hardness, from what I've been reading, 70D for o-rings is pretty standard in normal applications. The wipers are normally urethane it seems. I'm inclined to stay with standard. 20 years seems like so far in the future.

One question though. The original kit from Case has two wiper seals and an o-ring on the inner side of the head/gland. The wiper closer to the end of the cylinder is oriented with the "lip" towards the outside, fine. The other wiper has the lip towards the other end of the cylinder. When I opened the bucket cylinder I found instead of the wiper+o-ring a u-seal+ o-ring. From what I've been reading, a u-seal or u-seal+o-ring is superior to a wiper+o-ring. The cost difference is not much, just a few dollars. Should I stay with wiper+o-ring or use u-seal in this position? What do you think?

What are dimensions of groove? ID, OD and width?

For the lift cylinder head here are the dimensions of the groove:
A = 1
B = 1/4
C = 1/8


For the bucket cylinder head here are the dimensions of the groove:
A = 1-1/4
B = 5/16
C = 3/16

To answer exactly what you asked, for the lift cylinder head: groove ID = 1", groove OD = 1.25", groove width = 0.25"
For the bucket cylinder head: groove ID = 1.25", groove OD = 1.625", groove width = 0.3125"

These are the two u-seals I think fit here exactly well per these dimensions:
lift https://herculesca.ca/product.php?pid=2 ... 1.000-250B
bucket https://herculesca.ca/product.php?pid=2 ... 1.250-312B

by the way @FUTZ I cannot thank you enough for pointing me to the Hercules site, I find it amazing.

Here's the list of parts from Hercules for diy seal kit to rebuild the lift cylinder(s) and bucket cylinder. As far as I can tell the part numbers are exactly the same on both the Canadian and USA Hercules site. For reference,

USA https://herculesus.com
Canada https://herculesca.ca

The pdf file is here and I will update it if anything needs to change. I cannot guarantee the accuracy of this list until I rebuild my cylinders, but perhaps it's still useful to people.
