What should a guy be looking at on used 60-70' paralinks with 30K acres or so?
Thinking opener bushings, cylinders, hoses, wheel bearings, etc. What's the reasonable lifespan of these machines?

What model are you looking at? Our 3310 is a 2011 and besides hoses and some (a lot) of seal kits on the opener cylinders been pretty much trouble free. We did the main pivot bearings on the front castors a couple years ago.
We bought it used but likely has 50,000 acres on it

Probably a 3320. Local dealer sells lots of the seal kits, how hard are the cylinders to re-seal? I'm guessing you just check them with a heat gun to see which ones are by-passing, or do they leak externally?
I owned a 3320/7950 for a couple years so am familiar with the drill, just never ran it long to find out durability concerns.

What's happening to the "prototype" drill, or are you going to be running two drills?

When you get good at changing seals it takes me 10 minutes maybe. Plus time to R&R it. We just change the ones that are leaking oil. The 3320s seem to have less trouble with seals then the 3310. We get our seals from mikes hydraulics in Saskatoon. About a 1/4 of the price of bourgault.

What's happening to the "prototype" drill, or are you going to be running two drills? Only ran for one season and I never owned it, sold to another guy last winter. I'm a little back-and-forth between disc and hoe drill, so picking up a used hoe drill and keeping my disc will give me some flexibility. Used seeding equipment is a lot easier to stomach than new stuff on the pricing too. If I could pick one unit and price was not a factor it would be a K-Hart with some sort of older tank that wasn't so complex. Looking at the new Bourgault brochure I can't even figure out what they are offering anymore it's so complicated! |

I didn’t think these small rams could be take a part and resealed?
Opener bearings should be checked, if greased properly will be fine though. Bushing should be fine at 30,000ac on a large machine.

In the last 3 years I’ve done almost all the rams on our 3310. Ive done a few on 3320s for guys also. Not sure on the newer ones… but they have to come apart somehow cause they were put together.

I went to parts and looked at one of the rams. The cap has flat spots so looks like just put in a vise and put a bar in the end and spin it apart. I wonder though do they wear at the end on the pin?
Going to look at one tomorrow, so will find out more.

Never seen any of ours worn. Just the seals are destroyed when I pull them apart.
I put the ram in the vise with a bar through the end to hold it. Then I put a big pipe wrench on the flat parts and give it a hit with a 10lb dead blow hammer. It takes a bit to snap them loose.

So I bought this thing, a 3320 QDA. Turns out the depth cylinders are different than the 3310, but the MRB cylinders are like the 3310. Cylinders were all a bit damp around the rod ends with dirt stuck to them, figured it was likely normal. Needs the bushings that the opener attachment vertical arm pivots on, and the bushings on the front of the main arm, packer bearings and midrow bearings. Not all failed but enough loose so will do them all.
Tires all hold air and made it home 170 miles miraculously, but will likely get a few spares. The 6700 tank conveyor is rusty inside on the bottom, trucker said he has had them bend on the road before. Tank hitch looks okay, main part has a sticker so almost looks like it was updated but I might have to look into that.
Otherwise most stuff looks good. Wish I had a big heated shop to do the work in this winter, might have to park in front and drag hubs inside when necessary.

I have never changed a bearing on a paralink cause it was loose. Or a midrow bander and we have been running them since 2001. Have changed them when the dust cap came off or got damaged but otherwise just Tighten and grease and away we go.
The mrb cylinders will be different than the 3310 also as the 3320 uses smaller diameter cylinder to lesson the hydraulic requirements and speed up the lift and lower. Dust sticking to the rams is pretty normal as they sweat a little bit. As long as oil isn’t dripping out I wouldn’t worry about it.
I’ve got 4 16.5x 16.1 tires on rims if you need a spare. I changed over to a 445/50-22.5 tire on main frame. Tire and rim was cheaper then just the tire and they are a heavier rated tire.

One other thing to check is the walking axle bearings on the front of the drill. Especially the main frame ones. Some owners don’t know they are greaseable

Some of these bearings are definitely sloppy. Walking axles were supposed to be checked before it got towed but I will again. Rear walking axles on main frame didn't seem to have a grease point but I didn't look at the front yet.

Rears don’t have a grease point. Or they didn’t on the ones I have ran.
