Restricting the top link… advice?

I ordered two of those... one to slow down the top link and (hopefully) get rid of the "chatter" when extending the ram... the other is for the side link... just to slow it down...

Now the wait begins... c'mon UPS!!!

Got the top link off the tractor and the quick connectors removed… I say “connectors” because when I removed the ram side connector ( where I’ll place the restrictor) I found the dealer used Teflon tape to seal the threads… got all the tape off the threads and everything cleaned up with alcohol… I have some Rectorseal Tplus2 in my stash, so that’s what I’ll use for assembly…

once I get the hose/restrictor/connector assembled do I need to bleed any air out of the system or are all modern cylinders self purging? (My double pilot check valve needs to be installed with the valve body under the cylinder due to clearance issues… does this make any difference?)

I never purged my grapple when I put the restrictor in. I never experienced any side effects either.

I ordered two restrictor… one for the top and one for the side…

I put the top on the ram end hose and gave it a go… nice, smooth, slow extension… AND NO MORE CHATTERING … unfortunately the retract was still “full” speed… no restriction…

I placed the other restrictor on the closed end hose and was rewarded with slow retract movement… I’m guessing these are one-way restrictors…

I’ll order two more restrictors for my side link… life goes on…

thanks to all who helped get me on the right road…

Just an FYI for anyone else looking, we sell 1/4, 3/8, and 1/2" NPT fixed restrictors on our website.

If hyd hose has a male coupler just remove male coupler try inserting a dime with a hole drilled in the center between male tip & hose end. I know JD offers similar type restrictors(item 34) but those are much more expensive than a 10 cents

I haven’t taken the tilt hoses apart yet … although, I need to — to remove the teflon tape used by the dealership…

reading up on the alloy used in the minting of modern dimes (cupronickel), the use of a “10 cent” restrictor might just work… if I can manage to poke a 1/32” hole in one (I don’t own a drill press…SACRILEGE!!!)

Thanks for the suggestio…

Even if you DID have a drill press, it'd be pretty unlikely it would grab a bit that small - I ran into that several years ago when trying to use my press to drill some #60 holes in circuit boards - ended up buying a smaller chuck replacement (1/4" max), adding a fine thread grade 8 bolt to the new chuck, slicing off that bolt's head - then mounting the SMALL chuck in the larger one.

A 1/32" bit is .0313", that's .0003" larger than a #68 drill - (numbered drills get smaller with higher numbers)

You CAN buy 1/4" hex chucks, some will close to ZERO - I have this one

it goes down to at least #76, which is quite a bit smaller than the 1/32" you're after.

If you have a way to hold a dime steady (like a small vise) you could just center punch a small divot where you want the hole and your handheld drill (maybe WITH the above adapter, if your drill's chuck doesn't go to zero) should do well enough for your flow limiter... Steve

Oh, bits that small aren't as easy to find as bigger ones, if all else fails -
