0745-396 and 0745-426 appear in the same Arctic Cat starter reference group, alongside 0745-438 and 0745-488. Use those numbers to identify a candidate replacement, then confirm the exact snowmobile model, year, and original starter flange before ordering—not just the reference-number match.
How the four references are listed
The supplied product record distinguishes a stated replacement reference from additional group entries:
| Reference | What the supplied record says |
|---|---|
| 0745-396 | Main reference for this product entry |
| 0745-426 | Described in the technical notes as a replacement number for 0745-396 |
| 0745-438 | Included in the same reference group |
| 0745-488 | Included in the same reference group |
That wording does not establish an official manufacturer supersession history. It also does not document a replacement sequence through all four numbers or prove that every assembly bearing one of them fits every listed application.
The 0745-396 / 0745-426 product listing is the relevant catalog entry for this comparison. Arctic Cat identifies the listed vehicle applications; it is not a statement of genuine-brand manufacture.
Which specifications are available for this group?
The supplied entry lists these technical details:
| Feature | Listed information |
|---|---|
| Rated voltage | 12 V DC |
| Rotation | CW, or clockwise |
| Pinion tooth count | 9 |
| Construction | PMDD, or permanent-magnet direct drive |
| Mounting | OE-specific flange mounting |
The mounting notes do not supply a uniform hole-spacing or mounting-angle dimension. Those details require comparison against the specific OE reference and original sample. The entry also does not specify the viewing direction for its CW notation; request that clarification when comparing rotation information.
Treat the table as the source-listed description, not as a substitute for application and flange confirmation.
Confirm the exact model before comparing the flange
The application record distinguishes model years and detailed model designations. A broad family name alone is not enough to resolve snowmobile starter motor fitment.
Send the supplier:
- The full snowmobile model designation, including its variant or trim suffixes.
- The established model year; record a registration date separately if the model year is unknown.
- The original starter number exactly as marked, preferably with a clear photograph.
- Any known engine changes or previous modifications that could affect the original application.
Ask for confirmation against that specific machine rather than asking whether the starter fits “Arctic Cat” generally. If the old unit is marked 0745-438 or 0745-488, preserve that number in the request instead of replacing it with 0745-396 simply because the numbers share a listing.
Request a flange comparison, not an appearance match
Because this entry leaves hole spacing and mounting angle unresolved, provide a mounting-face photograph and a labeled measurement record or drawing. Identify the units and the points used for each measurement. Keep measured values separate from estimates.
The comparison request should cover:
- Mounting features and spacing: identify each attachment location and the center-to-center measurements being compared.
- Flange and housing orientation: show the mounting face, drive end, and overall unit so the proposed starter can be compared with the original.
- Terminal position: include a terminal-side view and request confirmation of its position relative to the mounting arrangement.
- Outstanding differences: ask the supplier to identify any unresolved dimension or conflicting detail rather than assuming a visual match resolves it.
Photographs document visible features, but they are not scale drawings. Where the original unit or reliable dimensions are unavailable, leave flange fitment explicitly unconfirmed.
Suggested confirmation request
My original starter is marked [exact reference]. The snowmobile is [full model designation], model year [year]. Please confirm whether your proposed 0745-396 / 0745-426-group starter fits this exact application. Attached are the original marking, mounting-face, drive-end, terminal-side, and overall photographs, plus labeled flange measurements. Please compare the hole spacing, mounting angle, and terminal orientation, clarify the viewing direction used for CW rotation, and identify any remaining fitment uncertainty.
The useful outcome is a reply identifying the proposed reference and the specific application and flange details checked—not merely a reply repeating the four-number reference group.
