Original MTD 61002-188 — Gearcase oil seal (single unit)
Restore a leaking or worn gearbox with this genuine MTD gearcase oil seal, part number 61002-188. It’s the shaft seal used in the transmission/gearcase to keep lubricant in and grit out — a single-lip oil seal supplied as a replacement part for affected MTD/Lawnflite/Cobra machines.
What you’re getting
- One original MTD gearcase oil seal (61002-188) designed to press into the gearbox bore and seal the rotating shaft.
- Made and specified for Danarm/Cobra/Lawnflite-style gearcases (listed under Danarm/C0 part references), sold as the manufacturer’s replacement seal.
Example machines it fits
- Danarm / Kaaz: LM4851KXR, LM5360HXAR, LM5360HXR.
- Cobra: RM48SPK, RM53SPH (including RM53SPH Pro) and transaxle models such as TN1951SXRK, TN2160SXARH.
- Lawnflite / MTD-series: 448HR, 448KJR, 553HRS and related Lawnflite-Pro models. These model examples match listings for part 61002-188.
Quick installation tips
- Remove the gearbox housing, clean the bore and shaft, check the shaft for wear or scoring, and gently press the new seal squarely into the bore until it sits flush. A light smear of compatible lubricant on the lip helps initial seating and prevents dry start wear. Avoid hammering directly on the seal lip or distorting its outer case. (No special tools required beyond a suitable driver or socket that matches the seal outer diameter.)
Why this part matters
A worn or torn gearcase seal lets oil leak and dirt enter the gearbox — replacing the 61002-188 restores proper sealing and helps prevent premature gear or bearing failure. If you’re searching for reliable power tool parts for a mower or garden machine with a leaking gearcase, this original MTD seal is the direct replacement called out on parts listings for the models above.
Sold individually — one seal per order.
