Is that washer thicker than .010”? The thin washers are .010” the washer should be close to .050”.

You will find problem. I think with hyd systems acting up, right after someone that shouldn’t have been working on the system, because of lack of knowledge, is like playing with a jig saw puzzle with pieces missing or in the wrong spot! Proper parts books, and shop service manual, put all jig saw pi...

Ok. Good luck

You will probably find a .010 shim will change hyd pressure 80 to 100 psi

When you get your new washer, would you measure thickness and post on here, in case someone else has similar problems, it would be for all to see! Also, after you install new washer and your 3 thin shims, and warm oil and pressure test, post on here what is pressure of your system, and if you have t...

Welcome to trouble shooting/ adjusting hydraulics !!
Drip cans, soaker pads and wipe up rags are a must have part of ones tool box!!

Did you try and measure a regular flat washer ?

Another suggestion - when you are testing hyd pressures over 300 psi, do not use brass or copper fittings, they won’t stand the elevated pressure and personal injury could result.

I found a listing for your 450-c on line and believe your hyd pressure is 2250 psi.

Forgot to say- get a bunch of .010” and install them, if you would rather. Put 5 or so in and try it. All the washer does is make it so you don’t have a bunch of thin shims. I always install thickest shim next to spring, that way spring action over time won’t distort thick shim( it will distort thin...

The T10649 washer is available on eBay , the thin shim you have should be U10562 and is .010” thick. Get a regular flat washer,( O.D. Of washer should be close to OD of thin shims), ( use a flat washer from your hood or floor plate) measure the thickness, install it, follow my previous post, or orde...

You need to find out what the hyd pressure is supposed to be, and at what RPM. Then put a pressure gauge( approx 1000 psi more than what your spec is) and a good gauge, then bottom a function so pressure is max. Record this reading. If it’s low, put in .050 washer or approx,but measure so you know h...

I would try and start engine with the inj pump that is on it. It may just surprise you, and then run pretty good.
Just my thoughts

Thanks. If you could, the thickness of the plate would be excellent !

Very nice!!
