Not wanting to highjack the other equalizer spring post, but I also have a question regarding the small, or sometimes called "stabiliser" spring pack.
Could some one please explain the function of this small spring assembly. I'm only guessing that it that it's function may be to keep the equalizer spring level or in a centralised position.

The reason I am asking is that I have a d4 6U with the small spring pack missing and am wondering if I am in mortal danger of something nasty developing with out it. Should I be looking at finding a replacement?

Thanks in advance.

Without the auxiliary spring fitted, there is nothing holding it to the crankcase and the machine can flip over backwards leaving the tracks on the ground, a very dangerous situation.

Someone posted a couple of photo's years ago that had flipped due to the equalizer spring either not being in place or had lost the hold down pins.
VERY DANGEROUS INDEED!
Please for the sake of all Fellow Members do NOT operate the tractor until this is repaired!

Hi Geoff, A lot of the old Cats I see here in Oz have busted that equalizer spring off including my "Good" RD6 so I just made up some brackets and fitted them both sides of that crawler for safety sake, the purists may not like it but I reckon it beats scraping me off a upside down Cat and will do on my flat farm till I find a genuine equalizer spring for her.......
regards
Mike

Sorry all, but I don't think I described my situation too well the first time around.
Thanks for all the concern though. I do appreciate the danger of not having an equaliser spring fitted and have checked that what I have will provide the protection required to prevent a back flip.
I know I have used the wrong descriptive wording for the small spring in my initial message, but thats all I could find to use.

What I meant to ask about was the small spring assembly that fits under the equaliser spring.
My parts book calls the small spring on my D4 6U the L-1195 spring, it's a five leaf spring and this is the one that is missing from my machine. Sorry I can't post a picture of it to show you what I am talking about.

Currently I only have the shackle assembly fixing the equaliser spring to the engine and it looks pretty much like the photo that Mike has kindly posted.

Thanks again for any info.

Same deal applies Palmer. That smaller spring absorbs any "upward" bounce, and then ultimately those straps shown in Mike's photo, which are also where the small spring attaches to, will limit the travel. The small spring just softens the hard stop as the tractor rears. The other important point about preventing rearing is that the outer ends of the main spring need to be secured to the track frames in such a way to prevent the spring lifting up and out. For the smaller tractors, a bolt through the spring seat stops the spring from coming up and out of the seat bracket.

Thanks Neil,
Understood now.

Cheers.

I don't see why a guy couldn't make a small trailer spring work.

It would be interesting to find out what a spring maker would charge to make a new set, as you point out jmvmopar they are not very big or heavy, I'd assume $300 maybe?

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
