Frequently Asked Questions
Why are my Bobcat glow plugs not working?
The most common causes are a burned-out plug, a failed glow plug relay, or damaged wiring feeding the plugs. If one plug has failed, the engine may still start but will crank longer and run rough until it warms up. Testing each plug helps you find out whether the plug itself or the circuit is the problem.
Where is the glow plug location on a Bobcat skid steer?
Glow plugs thread into the cylinder head, with one plug per cylinder. Each plug has a terminal on top where the power wire or bus bar connects. The exact access point depends on your loader model and engine.
How to test Bobcat glow plugs?
Disconnect the power lead and check each plug for continuity with a multimeter, from the terminal to engine ground. A plug that shows no continuity is open and needs to be replaced. If all plugs pass, check the relay and wiring next.
Which glow plug fits a Bobcat S650?
We carry glow plug 7008500, which fits the Bobcat S630 and S650. For the S100 and 553, we offer plug 16851-65510 for D905 and D1105 engines. If you are unsure which engine your loader has, call (800) 909-7060 and our parts team will confirm the correct plug.
Should I replace all the glow plugs at once on a Bobcat?
Many owners replace the full set, because plugs wear at a similar rate and the others are often close to failing. Replacing them together also saves pulling the engine area apart a second time. At minimum, test every plug before deciding to change just one.
