Brand new here, sorry for any mistakes I make in posting here or if I ask questions that are already answered, I browsed for a while and couldn’t find what I was looking for specifically. I recently purchased a 1959 D14 in relatively good working order. It needed a new starter, so I fixed that and it was running well. Recently front loader stopped going down. I checked all the hose connection and everything external that could be checked and decided I needed to look at the hydraulic linkage inside the case. Took the reservoir off and found that the hold position valve wasn’t working properly. So I took the pump out to be able to open that up and found a completely different problem. One of my cam shaft follower bearings has lost its outer casing and has a huge chunk ground out of it. Amazingly the clutch shaft is in good condition, but the other bearings have pockmarks now from where the metal shavings that got loose on the hydraulic fluid have been grinding into them. Does anyone know where I can purchase these bearings or what the size is on these bearings so I can just replace them rather than buy a full pump replacement on eBay? I can’t seem to find that information. Thank you in advance for any assistance rendered.

When the shaft is separate form the rolling element and passes through the inner race, they're typically called 'yoke rollers' rather than 'cam followers'. I'd be surprised if you can't find one from a supplier like Carter, Smith, RBC, or McGill. Any industrial/bearing supply should be able to order from them - they're the more common manufacturers of cam followers & yoke rollers: Carter Catalog for cylindrical, unsealed yoke rollers: https://carterbearings.com/products/line/ynb" rel="nofollow - https://carterbearings.com/products/line/ynb NTN also has a good selection, and a very convenient sorting/filtering tool to find the size you're looking for: https://bearingfinder.ntnamericas.com/category/roller-followers

| I'd be very surprised if you can find any of those other than another pump or AGCO themselves. As far as I'm concerned that is an OEM part specifically designed for that hydraulic pump application and nothing else. |

I think I just may have a couple of them in my NOS parts. It may take a few days to find them. I know I have a completer take-out pump from a D15. ------------- If it was fun to pull in LOW gear, I could have a John Deere. Real pullers don't have speed limits. If you can't make it GO... make it SHINY |

sounds like a GREAT reason to fin a 'parts tractor' !! though if you're like me you'll get it to run, then have to buy a 3rd, oopsy, get it to run, then #4 comes along.....  ------------- 3 D-14s,A-C forklift, B-112 Kubota BX23S lil' TOOT( The Other Orange Tractor) Never burn your bridges, unless you can walk on water |

Glad I'm not the only one that's fallen into that trap!

Tone indicator- Informative, not argumentative. I referred to them as cam followers because my service manual, parts guide, and operators manual all refer to them as cam followers. I will keep the preferred nomenclature in mind however, thank you for that information. And thank you for the leads on finding them. |

I'm not a man of enough means to have two or three old tractors laying around, I barely managed to scrape up enough for this one. Got a couple of broke ass motorcycles and an old suzuki sidekick that also wish I had part vehicles for them. |

[/QUOTE] Yup, we use them all the time at work and we all call them 'cam followers' most of the time too. Only reason I mentioned the 'yoke roller' name was in case you're searching the interwebs for suitable equivalents/suppliers.

| Amazing the clutch shaft isn't tore up. One of the WD45's I bought had rollers that looked like that from having no oil in the reservoir. The lobes on the clutch shaft were equally as ugly. Local tractor salvage yard had a bin full of shafts and cam followers. |
