SHAFT SEAL RING 37X52X14 MM AL68702

Shaft Seal Ring 37x52x14 mm AL68702

The AL68702 shaft seal, sized 37x52x14 mm, corresponds to an older model indicated by reference number 4 on the relevant assembly drawing. It is used in applications documented for John Deere, Case and Ford tractors. To select the correct part number, it is essential to verify the dimensions, the part number on the exploded view, and the assembly version.

The role of this seal on a rotating shaft

A sealing ring is placed around a shaft to maintain the seal of a mechanical assembly. In typical use, this type of seal helps keep lubricant within its housing while limiting the entry of dust or other contaminants from the outside.

For this part number, the key information is not a specific design but its use as a shaft seal with precise dimensions. It is this dimensional match that allows you to find the correct part when replacing it.

Key features to check when identifying the AL68702

The selection of this bushing is based primarily on the dimensions 37x52x14 mm. This is the most direct way to compare the removed part with the replacement part. The part number AL68702 then helps you find the correct item, especially if you’re working from a parts list.

• Dimensions 37x52x14 mm to confirm that the housing and shaft match
• Partnumber AL68702 for identifying the part
• Part No. 4 if you are using an exploded view
• Old model if your machine has undergone a design change

When multiple versions exist for the same machine, it’s important to verify whether it’s an older model before completely disassembling it. On a tractor that has been repaired in the past, a visual comparison with the removed bushing is also helpful.

Applications found on John Deere, Case, and Ford

This bushing is found on several agricultural tractors from the brands listed in the compatibility chart. For John Deere, it is found in particular on models such as the 1550, 1640, 2040, 2040S, 2250, 2450, and 2650, as well as on certain variants such as the 1630OU, 1630VU, 1750V, 1850N, 1850V, and 1950N.

Applications are also found on tractors Case, for example in XL versions such as the 485XL, 585XL, 745XL, 844XL, 895XL, or 995XL, as well as on several Ford tractors such as the 5110, 5610, 6610O, 7610O, and 8210. Depending on the installation, a serial number restriction may apply to certain John Deere applications.

Useful Checks Before Replacement

Before selecting this part number, compare the dimensions of the old bushing, note its part number if it is still legible, and check reference point #4 in your documentation when available. A difference in version or installation date may be enough to indicate that a different bushing is needed.

If you are working on an older tractor or a machine with an incomplete repair history, also verify the exact model and, if necessary, the serial number. These simple checks will help you more reliably identify the correct seal for your application.

FAQ — Frequently Asked Questions

What is this shaft seal used for?

This sealing ring is mounted around a rotating shaft to ensure the assembly remains sealed. In typical use, it helps keep lubricant in its housing and limits the entry of contaminants. For this part number, the primary verification criterion is the dimension 37x52x14 mm.

How can you identify the older model, part number 4?

Identification is based primarily on the installation method and the dimensions 37x52x14 mm. The notation “old model” and part number 4 are helpful if you are working with an exploded view or parts documentation. Also compare part number AL68702 with the removed bushing before confirming the replacement.

Does part number AL68702 apply to the John Deere 1550, 1640, 2040S, or 2650?

Yes, this part number is listed among the documented applications for several John Deere tractors, including the 1550, 1640, 2040S, and 2650. However, depending on the installation, a serial number restriction may apply. It is therefore best to confirm the exact model and version before ordering.

Can it also be installed on Case, 485XL, or Ford 8210 tractors?

Yes, applications have also been identified on Case, and Ford tractors, including models such as the 485XL and 8210. You can confirm the correct choice by cross-referencing the exact model of the machine with the dimensions 37x52x14 mm and the mounting reference when you have the machine on hand.
