Re: Virginia 450 Help

Thanks Lavoy. Makes more sense to have both sides brake. I havent dug into the service manual on this. Finding what you need in there is a bit of an art Im learning.

Re: Virginia 450 Help

Ok well lets hope for the best. Its a 4239 D motor from French JD plant. I was told it was put in sometime in the 90s in a refit. Dam thing runs great. No smoke. Starts immediately even when cold. That would really suck if I needed a rebuild. I will do everything you suggest. Just replaced water pum...

Re: Virginia 450 Help

I GOT IT FIXED! I found detent. I think that bolt was gummed up from brake dust and dirt. Anyway detent seemed to magically appear and was able to get more turns out of the adjuster bolt. Then readjusted the lever adjustment and started making progress did it all again with a little more shim under ...

Re: Virginia 450 Help

Ok and so the linkage goes across and both bands are used at once for the pedal brake right?

Re: Virginia 450 Help

Thanks Amos Cylinders sound like a beast. You can see on mine where someone struggled at one time or another with the spanner. I found a guy that will replace the bands and fix the cylinders. He said ¨sometimes they are a bear¨ Ok on detent - something like that is what I thought it meant BUT I feel...

Re: Virginia 450 Help

Tighten the brake band adjusting screw until tight when not in detent (1/4 turn past detent) What does ¨when not i...

Re: Virginia 450 Help

Thank you Amos
I will be pulling them off and taking to a shop. Sounds like that is really reasonable to get them worked over. I have two that need attention on the machine. Need to get the hoe going and will probably need a couple there too.

Re: Virginia 450 Help

Amos Thank you very much. Very sound advice. I will reconsider a quote from the JD Dealer and share some info on that. I wish I had the time to take it on. Another question while we are at it. Would you take on rebuilding hydraulic cylinder yourself? Never done it but my lack of fear of trying somet...

Re: Virginia 450 Help

Amos Thanks for the reply and sorry for my delay. I have been adjusting as needed and now the band adjustment bolt in the side access is bottomed out. I have been using the process/procedure as laid out in the manual. I assume this means I need a new brake band or is there some other adjustment to c...
