Product Description
🛠️ Stop Arm Cylinder Rod Leaks – LC01V00054R100C Front Repair Kit
Is your Kobelco SK350LC-8 or SK330-8 excavator leaving puddles of hydraulic oil under the arm cylinder? Is oil dripping down the chrome rod near the front gland?
You need the LC01V00054R100C Arm Cylinder Front Repair Kit.
This kit is specifically designed to rebuild the front/gland end of your arm cylinder. It contains all the seals required to stop external rod leaks, keep contamination out, and restore proper cylinder performance.
⚠️ Note: This is the FRONT repair kit (rod/gland end). For full cylinder rebuild (including piston seals), check our LC01V00054R200C or full kit options.

🔍 Compatibility – Check Before Buying
⚠️ How to verify 12 holes:
Remove the arm cylinder, separate the piston from the rod, and count the bolt holes on the piston face. If you see 12 holes, this LC01V00054R100C kit is correct for the front end.
❌ Will this fit SK330LC-8?
Yes – SK330-8 is compatible. SK330LC-8 (with canopy) uses the same arm cylinder as SK330-8.
❌ Will this fit SK350HDLC-8?
No. The HDLC-8 models use a different part number. Please check our LC01V00070R100C/R200C series for HDLC-8 machines.
🚨 When Should You Replace the Front Repair Kit?
Replace the LC01V00054R100C front repair kit immediately if you notice:
📌 If your arm drops slowly under load (internal bypass), you need the rear/piston seal kit – not this front kit.
🔧 Installation Overview
Tools needed:
-
Cylinder gland nut wrench (or spanner)
-
Pick tools for old seal removal
-
Soft-faced hammer
-
Clean hydraulic oil (for lubrication)
Basic steps:
-
Remove arm cylinder from excavator
-
Drain hydraulic oil
-
Remove gland nut or retaining ring
-
Extract old seals from the gland
-
Clean gland thoroughly – inspect for scratches
-
Lubricate new seals with clean hydraulic oil

⚠️ Critical: Rod seal lip must face the pressure side (inside the cylinder). Incorrect orientation causes immediate leakage.

❓ Frequently Asked Questions
Q: How do I know if I need the front kit (R100C) or rear kit (R200C)?
A. If oil is leaking from the front of the cylinder (where the chrome rod enters), you need the front kit (R100C). If the arm drops under load but no external leak, you may need piston seals (R200C).
Q: My piston has 14 holes, not 12. Will this fit?
A: No. This kit is only for 12-hole pistons. Please check our LC01V00070R100C series for 14-hole configurations.
Q: Is this an OEM Kobelco part?
A: Aftermarket premium quality manufactured to OEM specifications. Not original Kobelco branded but direct replacement.
Q: Can I install this kit myself?
A: Yes – with basic mechanical knowledge and proper tools. We include a seal orientation diagram. For first-timers, we recommend watching cylinder repair videos or hiring a hydraulic shop.
Q: What if my rod is scratched or pitted?
A: Replacing seals alone won’t fix a damaged rod. You’ll need to replace or chrome-plate the rod. Contact us for rod replacement options.
Q: Do you ship to [country]?
A: Yes – we ship worldwide. DM us your postal code for a delivery estimate.
