Great news . Have fun operating it . Dan

I read on a site about a foundry here in Pennsylvania run by the Amish that would cast parts for old equipment , I will see if I can find their name and send you the information . Dan

Lavoy , did you ever get a good track stop for the 420/430's ? Reason I am asking is I will need two when I get back to working on mine both of them are worn through on mine . Dan

A little more information would be some help here . Okay that said , when you pull the steering clutch lever to the rear with the engine shut off does the throw out bearing contact the clutch fingers ? IE is it adjusted properly ? If it is not adjusted correctly than you need to adjust it before pro...

Gil , how badly are the front idler guide flanges on your track frames . If they are thin then this would be the time to fix them also . That will be my next project on mine as both sides are getting bad . I will be posting pictures of the repair as it progresses . First thing to do is get figure ou...

Three things to test , 1. test for voltage at the coil , coming from the ballast resistor should be 6 volt or there abouts . If you have voltage there than the switch is working correctly . 2. Test or voltage at the distributor with the wire coming from the coil disconnected from the terminal on the...

Crossing asphalt or concrete can be done with old tires , line up the tires with where you want to cross the surface (drive over them) . I have done this with excavators up to a Cat 320 and not left marks on the road . As for tearing up the grass just use one path and then fix it when you are done w...

Okay I know this is a stupid question but it has to be asked , Since I have to rebuild both final drives on my 420 , pull the center frame to get the clutch pedal and brake cross shaft freed up , fix the lip that the idler sets on on both sides of the crawler , and repair the one side frame cross me...

Could be worse , I have seen a few five ton dump beds in the Army laying on the ground . Put some new framing under it and you are back in business . Dan

The work is progressing slowly on the crawler , I brazed the holes shut on the blade control handle and re-drilled them , now it is setting in the box for the machine shop to check the main pivot point for trueness and sized for a new bushing which he will be making . I have some brass rod to make i...

My parts manual list the jam nut for the bottom rollers as a 3/4 and the bolts that bolt the roller to the track frame as 1/2 " . If you are talking about the Idler wheel it lists them as same . TIP ALERT : If you are having trouble determining a shaft size use open end wrenches to measure the diame...

Lavoy , did not get to it today , will see what the morning brings . Trailer welding turned out to be a bust as the crossmembers are all shot , will need to build brand new bed for trailer before using it again . Gotta love road salt Thanks for the info . Dan

If the blade control handle is cast steel I will tig build up the worn parts of the holes with ER70 filler wire , is it is cast iron I am going to braze them up , then drill them out to the same pin diameter . I thought of cleaning up the holes with a 1/2" end mill then pressing in a bushing made fr...

I will have to get the idler wheel off and the blade off of it before making a decision on how to rebuild it but from what it looks like , the flanges thickness is too thin to take a build up . I have to repair the pin holes in the blade control handle as the pins have egg shaped the holes . I am he...

Lavoy I have the hood off the crawler and have the shaft wedged forward , I was planning on building a puller tonight but I am stuck in front of the computer wet nursing a friend on the web through putting in a water heater on another board , it is slow but he is getting there his last post he was r...
