A big shout out to Lavoy, Love you man! Today finished tightening the last nuts and bolts on my 420-C and tensioned and aligned the tracks and she is back in business WAHOO!! Now to work! Thanks again Lavoy!

Thanks Lavoy, I'll try to be gentle

Hi all, been awhile since I've been here. Rebuilding my right hand idler assembly with a lot of help from Lavoy, bless his little heart! Anyway one of the new/used brackets has a little ovaling where the shaft fits and I can't seem to get it to slip on. I micd it at 25.40 mm but it narrows slightly ...

I'm not sure if this will help but I have the test specs for the delco-remy gen/reg for the MC, 40C-420C-430C &4401C Attached:

WOW!!! And here I thought I was something special with my 6 cords last month But now I gotta stack it, any one want to come out to calif?

What do you mean by "a lot of work" did you fabricate yourself? Thats awesome, what kind of wire feed do you use? I have a stick but am looking for wire feed.

Hey, notmeu that 6 way blade must do some awesome work! My loader won't do dat

Thanks Stan, I am unfamiliar with the JD brand, I,ll have to do a little research for the old girl, wait a minute I'm 5 yrs older than her By the way how do you like the blade on your 420, mine has a loader.

Has anyone an opinion on types of oil for an older JD crawler, detergent or not, friction additives? any additives?synthetics? With all the new tech on oils I'm torn between upgrading or sticking with the tried and true 10/W30 plain old oil?Any help on this is,as always much appreciated

Sorry Jim I had about 8 things going on here at once and didn't proof read. It's a JD- L 420-C. The springs are about a 1/4" off factory specs, big deal? I am not sure, the problem is the adjusting nut will not budge, do I worry about or is a 1/4" no biggee?

Any ideas on this, My spring measures 1/4" shy of the factory specs, should that be a concern or chalk it up to years and wear, I can't get the adjusting nut to budge, soaked for three days still nothing? Spring pressure must be holding, how to release pressure so I can adjust if necessary? Thanks f...

Why can't you drop a track at the barn door or the lawn in front of the house, oh right, it's Gods way of sayin, you're havin to much fun!!

I carried the .1204 to far is all, it's still .120 or close the bushings vary a little side to side, probabably should replace, still almost an 1/8" thats too much, so let me know what you can supply.

Once again I may have misled, apologies, Here's the comp's !: Factory specs on Idler & roller shaft (they're the same) 1.981- 1.982-----------I read 1.9625 2. Idler & Roller Bushings---factory: 1.983-1.987------------------------------------ Read------2.037- 2.0125 opposite sides diff of .1204 from ...

Front Idler torn apart roller shaft mics 0.020 diff than factory specs, roller bushings mic.1204 diff, replace ? do it now cuz it's tore apart, let it go cuz it's a tractor by gosh?As always any help will be appreciated to the max
