Re: Clutch on JD450C

Hi, One issue that can occur with a clutch is the pilot shaft on the trans input shaft sticks into a hole in the engine crankshaft which has a bushing in it. If that gets sticky the input shaft will still turn even with the clutch disc completely disengaged. That leads to gears grinding when trying ...

Re: Buying Guidance

Hi, In my case, I was trying to talk my wife into a JD350. But, I can't get another crawler unless she gets a new 10x20 garden shed. Ok! Shed has duly been ordered! Ought to be here in two weeks. :) Also, this means her Gator will have its' own place in one end of the new shed. This frees up the mos...

Hi,

Ah. Both, then. That clears up the confusion I was having earlier.

Re: Clutch on JD450C

Hi,

The 350 with a reverser has a clutch pedal which operates a hyd valve. The 450 with HLR has a regular clutch IIRC.

Re: jd440 ic hydraulic pump/hyd cylinder

Hi, You should be fine. The only real issue with 20w v 10w is when the temp drops way down in the winter. Then, the heavier oil will cause the hydraulic system response to slow down. A secondary issue is if you have a seepage, then the 10w will dribble out faster than 20w in the summer. If any of th...

Re: jd440 ic hydraulic pump/hyd cylinder

Hi, You can use Non Detergent. It is sold as Motor Oil, but it works OK for hydraulic. The detergent likes to foam. It is an additive to collect combustion byproducts. Non-Detergent oil is Base Stock, minus additives. If the oil bottle label does not say Non Detergent, then I would leave it out of a...

Re: jd440 ic hydraulic pump/hyd cylinder

Hi,

Engine oil has a tendency to foam when used in Hyd systems. If it does, then you'll be thinking something went wrong with your repair.....

Re: birthday

Hi,

And, the old JDs turn a darker shade of green....my 420c looks more like an Oliver than a Deere these days!

Hope you had a Happy! :)

Re: proper color

Hi,

My starter and generator are green. The standard Delco color was black, so rebuild shops usually paint them black.

Re: 63 blade- hydraulic 6way conversion

Hi,

Ah. That is different than the usual PAT conversion discussion of a 62 or 63 blade, which involves simply adding hyd cyls and pulling out the pins.

Re: Help on figuring out 450 year?

Hi, That tag says it is a 1970, Straight (as in No Letter) 450 crawler, loader, Diesel, with an HLR. Lots of machines get new decals with the wrong letter, so that is probably the case here. It seems that decals with the letter 'C' get used a lot. That might be due to earlier models using 'c' to mea...

Re: jd440 ic hydraulic pump

Hi,

You know, if the blade will pick up the front end of the machine, the issue is not in the pump. I am thinking along the same lines as Lavoy.

Re: 63 blade- hydraulic 6way conversion

Hi, The 63 is essentially the same as my 62 (on a 420c). The design is not meant to run unpinned or unwedged. Conversion to hydraulic for the angle and tilt will require both. I expect that condition would destroy the left hand mount in short order. And, it won't be kind to the tilt track piece, eit...

Re: proper color

Hi, My still-original paint on my 58 420c has black on the seat frame. The rest matches what Lavoy has said. Being a 58, it is a Phase-III, so earlier ones might well have had green seat frames. Mine has the oil dipstick on the right, which was changed for the 430. So, maybe the seat frame paint col...
