Car Mechanic Simulator 2021 – Repair Bench Compendium

Found a part in a barn or the junkyard and you don’t know whether it can be repaired or not? Then this is the guide for you! Continuing on the work of my CMS2018 guide, this guide presents two lists: Parts that can be repaired, and equally as important, parts that cannot be repaired.

Preface

There are many parts available when wandering around barns and the junkyard that can be picked up for a bargain, but can those parts be repaired? Knowing what can or can’t be repaired can make the difference in picking up major parts and restoring them at a fraction of the store purchase price. Very useful when restoring that prize vehicle you’ve been working on.

This guide is primarily made up of two lists: parts that can be repaired and, secondly, parts that cannot be repaired. Knowing what parts are on what list can make the difference in whether you pick up something that is in a low condition that can be repaired or whether you leave it unless it is in good condition.

As in CMS2018, items have to have at least 15% condition before they can be repaired, so there is no value in picking up any part that is under 15%, whether it is on the repairable list or not.

In order to repair parts, you need to have unlocked the renovator ability and have purchased the workbench once you have expanded the workshop. Each level of the Renovator’s ability opens up more repairable parts as all parts are leveled. To begin repairing body parts, you need to reach level 6 of the Renovator ability and have purchased the body repair station.

Brake Discs and Batteries are not repaired at the Repair Bench but at the Brake Lathe and Battery Charger, respectively, which can be purchased through the Workshop after the workshop has been expanded (the charger can be purchased before the garage expansion). Unlike the Repair Bench, it doesn’t cost any money to repair the brakes and recharge the batteries.

The higher the level of the Renovator ability, the greater the chance to repair the part completely. At level 6, the chance is 60%.

When repairing, the repair sweet spot (green bars) is best to be attempted when they are on the ends. This effectively doubles their size as the cursor runs through them and then returns back. If the placement of the bars is not advantageous, you can cancel the repair and try again.

These lists are not yet complete and will be updated as I come across the different parts. Exceptions are listed in brackets. If you come across any errors, please mention them in the comments.

Currently, these lists represent the base game and current DLCs. Mods may have their own idiosyncrasies as mod authors may have used slots for unique modeled parts that may or may not be repairable. These items will generally be in the Body Parts section. I do use a lot of mods so I will add them as I come across them.

When I have tested and checked a greater number of the parts in the game and have filled out my spreadsheet a lot more, I will look at adding a link to a Google Sheets file that contains all of the parts in the game and holds further useful information that can be downloaded.
