I have what I believe is a original gauge. I have had it for ~10yrs. It is stamped “EXERCISE CLUTCH FINGERS “ and is stamped “JD227A” directly underneath the words. Best regards, Bruce

You may need to borrow Mom’s cloth measuring tape and make an approximate length measurement as Jim B has suggested. When you succeed, post the information back here for future reference, please. Best regards, Bruce

this is for a 75 loader on a 450c, not sure they are the same. You could compare some parts numbers at https://partscatalog.deere.com/jdrc/ The Deere web site for parts often lists the length of the hoses in the description under the part number http://www.jdcrawlers.com/messageboard/viewtopic.php?f...

There is a 1” hole in top of the right box lid. It is towards the rear of the arm rest lid. In that hole there is a vertical rod. It should have a roll pin or pin on the top. This rod is connected to the bypass valve and spring actuated. When the oil is at operating temperature, and you are raising/...

There is an often neglected filter in the right box/hydraulic box. It is either under the bolt on cast cap on top of the tank or in very late C series,?it is a spin on filter. You need to change this. Have you observed the pop-up head while raising and lowering the loader??

Does your tank have a spin-on filter or is yours old enough to have the filter in the tank? Has it been changed recently?

Is the fuel tank sump and drain line working? Glad your rig is running again, but if the sump isn’t purged occasionally the screen may have problems again.

I can't imagine that the liner has that kind of flex in it. If there was something on the ledge then the whole liner would just stick out. Like Lavoy says the math to make that thing tilt is mind boggling. I would be very curious to see that liner out on a known flat surfaced and measured. I think ...

I’m thinking damage to the low side or debris under the high side. It is not uncommon for debris to be left on the liner landing or to fall in with the liner installation. Hopefully no a block problem. I agree with Lavoy, just push the one suspect liner out. Port-a-power from the bottom on the liner...

While the pan is off, consider using some plasti-gauge in at least one rod and one crank bearing.

My guess is a aged oil pump and ever increasing bearing gaps in the crank, rods, cam and balancing shafts. It sounds like you have an otherwise good engine. If you are certain your oil pressure reading is accurate, you could consider an underhaul. It takes 10-12# of pressure to float the rotating ma...

Sounds like a great opportunity for a 2 crawler herd!!!

Welcome to the forum! Sounds like a nice project. This site has a dedicated pic site, read about it in the FAQ section. Best regards, Bruce

?were you able to change both hoses without removing the steel pipes as I described??

This last summer's project was to replace all 12 hoses on my 450C loader. I blew a boom lift hose out with a bucket full of dirt while on-the-job. I replaced mine with the machine in the field. I placed a thread on this site documenting the hydraulic hose size/dimensions etc. I rolled the bucket for...
