Designed exclusively as an optional add-on for routine upkeep, this spare parts kit is intended for enthusiasts who prefer having extra backups on hand.
Please note: Purchasing this pack is completely optional and not required for normal operation. All components included in your original Teching DM229 kit are durable, high-precision parts built to last under standard conditions. No parts require replacement unless you experience specific, accidental wear, damage, or loss during assembly or extended use. If your model is currently operating smoothly, your original parts are fully sufficient, and no upgrades or replacements are needed.
If your model is running smoothly, your current parts are more than enough and do not need to be replaced.
The latest version of the user manual is currently in production and will be available soon. Please download the digital version directly. Additional physical paper manuals must be purchased separately if needed.
If you require any other individual components not listed above, please reach out directly to our customer support team at service@stirlingkit.com with the specific part numbers and quantities needed (part numbers can be found in your product manual), and we will be happy to provide a quotation for you.
