2510 overhaul

[Tireboy]

I have a 2510 that needs a overhaul it has a block casting number T26933. According to on line John Deere parts the 2520 also used that same number block. Can I put in the pistons and liners for a 2520 for the block number T26933 in my 2510? Has anybody done this?

2510 I owned was a pain in the buns to get the right liner like 8 different engines fit in them

If you have the block number and Deere has one I would order ONE sleeve get a good part number make sure it’s the right size and length. Then match that sleeve to the overhaul kit for the tractor from whoever you like with a known good part number but it’s likely this will be piece by piece.

Tried ordering an overhaul kit from 3 different places and had to return 3 different sets. Including Deere once. They eventually got it right and yours I believe will be a 4-219 by the casting and if I recall that is the original?? Gee shouldn’t it be easier to have the right part the first time? Sure should. But the cost of one extra sleeve and checking fit will save you the month of messing around that I did. Could have gotten a lot done in that month! 4020 3010 find the casting you are good. There just aren’t as many 2510s around and everyone’s favorite displacement engine can get shoehorned in. Then an aftermarket place decides that will fit this 2510 it should fit…no it don’t.

I am sure the 2510 used the 180 diesel which one of mine has and the other 2510 I have has a later 219 diesel which has more power as well

Gas was 180 and diesel was 202, same as the 2020, I believe.

Yes you are correct Jim I was wrong I believe mine was a 4-202 when I went back and looked but was a gas I believe some of the swaps have engines of different fuels that are the same size

 

[Jim.ME]

Yes you are correct Jim I was wrong I believe mine was supposed to be a 4-202

I have a 2020 with a 180 gas. It took a bit of research to get the right liner kits. There was a difference in the liner sealing rings depending on the block used as I remember it, changing the liner kit needed.

In Tireboy's case I would say that if the liner sealing parts are the same for engines, using the same block number, it is likely the 4219 liners will fit in place of the 4202 liners. If he does some further research he should be able to find detailed dimensions of the liners and compare the dimensions of the two (ODs, heights, etc.) to see if they match.

If he can find a tech manual it should give him all the dimensions. When I did my 4020 I found out after market liners are not all the same. My first liner I got would slide in with no resistance, the next liner I got from a&i had to use a block of wood and a hammer

They are supposed to just drop in easily with no resistance. Never seen that on a JD, unless the block wasn't clean.

Guess u haven't read a tech manual

You are both correct depending on what stage of installing a liner you are talking about.

If checking the fit of the liner in the block without the sealing rings, mattheis is correct, it should go in freely.

When installing the liner with the sealing rings in place, after working them in by hand, a block of wood and hammer maybe needed to seat them, due to the friction of the seals. If you have to drive a wet liner in all the way with a block of wood and a hammer, I don't see that as correct.

I was putting the after market liner in with the new rings and it slid in with no effort at all , the after market liner was 25 thousands to small

2510- 180 gas and 202 diesel, then 2520- 202 gas and 219 diesel. I looked into putting 239 parts into my 219 block, but it was going to be too complicated, and experimental!

Including the info in this post about the liner dropping in with the seal rings on it vs having to use a hammer and block of wood on the second liner would likely have change the responses to your earlier post. I first thought along the same lines as mattheis, that you were checking dry fit and the liner should fit freely. Easy to have these mix ups with partial info.

Did your 219 block have the same casting number as a 239 block you were looking at using parts from? I may be wrong, but I think there were more changes between the 219 and 239 than there were between the 202 and 219.

His (2510) 202 diesel block casting number also shows up for a (2520) 219 diesel block and the liners used the same seal rings. That is why I said they may fit and suggested finding and comparing all the dimensions.

No. You are correct. The 239 block is different. With some machining and different connecting rods, (so I was told) we could make it work. But would it hold up? I doubt it. Interestingly, the 219 diesel, turned up 10%, was much more powerful than the 202 gas had been. Enough so the same clutch wouldn't hold it. Another thing- this 219 was prone to cavitation erosion. I was told that was a design/clearance issue. With my second set of sleeves I added a coolant filter with additive. Then it didn't bother again. Different/better material? Coincidence?
