Perkins Filter Kits

Perkins T402380 Engine Service Kit with Filters

A Perkins 1100 Series schedule service kit, listed for the 1104D-44TG2 and 1104D-44TG3 genset engines. Perkins states it covers one 500-hour and one 1,000-hour service. The box is not filters alone — it also carries a rocker-cover gasket and a fan belt. Listings disagree on one line inside it, so confirm your kit against the engine serial and build list, not against a copied description.

Which Engine the T402380 Kit Fits

Perkins lists the application as electrical power for the 1104D-44TG2 and 1104D-44TG3. In practice, those are the genset builds of the 44T engine. The industrial 1104D-44T is a different build, and the electronically controlled 1104D-E44TA sits under separate kit numbers again.

The 44TG2 and 44TG3 are generator-drive builds, governed and rated for fixed-speed duty. The industrial 44T is a general-purpose power unit. They share the same core engine platform — which is exactly why buyers assume one kit covers both. It does not. A kit number is tied to a build and an emissions configuration, not to a displacement.

Build, not displacement
A kit number is tied to a build and an emissions configuration. The 1104D-44T shares the core engine with the 44TG2 and 44TG3, but carries a different kit number.
Genset vs industrial build
The 44TG2 and 44TG3 are generator-drive builds, governed for fixed-speed duty. The industrial 44T is a general-purpose unit. Do not substitute one for the other.
E44TA is a separate family
The electronically controlled 1104D-E44TA sits under separate kit numbers again. State the exact build code in the enquiry so the kit can be checked.

What the T402380 Service Kit Contains

The contents below are the lines published by resellers and distributor listings for this kit. The Perkins product record names the application and the two-service coverage, but it does not publish a full contents list. The part numbers are the reliable field. Descriptions and quantities vary between listings, so the table carries a status for each line, and every line is confirmed against your engine build in the quotation.

Perkins numbers its service kits in a close sequence, and the numbers either side of T402380 belong to different engines. None is a substitute for another. The numbers sit one digit apart, carry the same naming pattern and are photographed the same way — that is how a buyer ends up with a kit for an engine one generation away from the one in front of them. T402611 is the clearest example: a 400 Series kit for a 403A engine, not a variant of the 1100 Series kits, and not interchangeable in either direction.

Genuine Kit, Individual Filters,
or a Filters-Only Kit?

The genuine schedule kit. One number, both services, and the gasket and belt included. The advantage is one contents list to check rather than seven.

The same components as individual lines. Buyers who already hold stock of one item, or who service several engines on different schedules, often order the lines separately. We quote individual lines the same way as the kit.

A third-party filters-only kit. Sold by machine model and split into 500-hour and 1,000-hour options. It carries filters and not the belt or the gasket — a different contents list, not a cheaper version of T402380.

Declare the requirement. If the kit must be a genuine original item, say so before we quote. Where an alternative is offered, it is labelled as an alternative, and no substitution is made silently.

What to Send for a T402380 Quote

Four things make the reply specific.

Engine model + full serial · old filter numbers · kit quantity · genuine or filtration-only

The engine model and full serial number; the number off each filter you are removing, or a photograph where it is worn; the quantity of kits required; and whether the genuine original kit is mandatory or the filtration contents alone will do.

No price is quoted before the lines are confirmed. Declare the genuine-original requirement before quoting, or the reply cannot be compared like for like.

What the reply will state.

The offered kit or the offered lines, the maker of each item, the complete part numbers and the quantities — plus availability against your list, the documentation and the delivery terms.

No real-time stock feed is published. For a fleet or dealer service programme, add the rest of the engines to the same enquiry; each kit comes back as its own line.

Frequently Asked Questions

What is included in a Perkins T402380 service kit?

Listings show two lube filters (2654407), one fuel/water separator element (4415122), two secondary fuel elements (4816636 or 26560201), an outer air element (26510342), an inner safety element (26510343), a rocker-cover gasket (3681A055), and a fan belt (2614B652). Confirm the lines and quantities against your build.

What engine does the T402380 kit fit?

Perkins lists it for the 1104D-44TG2 and 1104D-44TG3 genset engines. Confirm by the full engine serial number and build list, because the industrial 1104D-44T and other variants carry different kit numbers.

Does T402380 cover one service or two?

Two. Perkins states the kit contains the parts for one 500-hour and one 1,000-hour service. That is why the lube filters and secondary fuel elements appear twice.

Is T402380 the same as T402379?

No. T402379 is published for the 1104D-E44TAG1 and G2. T402380 is published for the 1104D-44TG2 and TG3. The numbers sit one digit apart and are not interchangeable.

What is the difference between 26560201 and 4816636?

They describe the same secondary fuel element at different points in its life. Parts sellers list 4816636 as the later number replacing 26560201. Check the number on the element you are removing rather than treating them as two filters.

Can I buy the filters separately instead of the kit?

Yes. Individual lines are quoted the same way as the kit. What you lose is the belt, the gasket, and the single contents list covering both services.

Is the kit genuine Perkins?

Genuine-original requests are accepted when declared before quoting. Any alternative we offer is labelled as an alternative, so you know which you are comparing.

Why do listings show different contents?

The secondary fuel element number has changed, and some listings mislabel the gasket and belt lines. Check the part numbers rather than the descriptions, and confirm the offered lines on the quotation.

Confirm the Build, Then the Box

Send the engine plate details, the old filter numbers and the quantity. We will confirm the kit or the nearest correct number in the family, and state the offered lines and delivery terms in writing.
If the number is worn or missing, photographs are enough to start.
