LiftMaster K75-19103 1HP Tension Rod for HS670GL Hydraulic Slide Gate Operators
The K75-19103 is the 1HP tension rod used in the linkage system of compatible LiftMaster HS670GL hydraulic slide gate operators. Its job is to help maintain correct mechanical tension and alignment through the pivot arm assembly. In a hydraulic slide operator, the linkage must stay square and properly preloaded; a damaged tension rod can allow the linkage to shift, bind, or apply uneven force during travel.
This is a horsepower-specific part. The 1HP version is not a safe substitute for the 2HP tension rod, and the final fitment should be verified by the HS670GL illustrated parts list. When replacing this rod, it is good practice to inspect the upper pivot arm, lower pivot arm, tension spring, rod ends, and mounting hardware because a worn companion part can quickly damage the new rod.

Technician Note
Do not reuse damaged or stretched companion hardware with a new tension rod. A tension rod failure can be a symptom of gate drag, linkage misalignment, or incorrect adjustment.
Before Ordering
- Confirm the operator is HS670GL and 1HP
- Do not use this part for the 2HP tension rod position
- Inspect upper and lower pivot arms for bent or elongated pivot holes
- Check tension spring and mounting hardware condition
- Verify the gate rolls freely and is not overloading the hydraulic operator
Professional Advisory
Mechanical repairs on heavy slide gates should be handled with the gate secured and the operator power controlled safely. A qualified gate technician should service hydraulic linkage problems where the gate is binding or under heavy load.
Important Ordering Warning
K75-19103 is horsepower-specific. Do not substitute it for 2HP HS670 tension rod applications.
Product Questions and Answers
What operator is K75-19103 used on?
K75-19103 is used on LiftMaster HS670GL hydraulic slide gate operators in the 1HP tension rod position.
Is K75-19103 used on 2HP HS670 units?
No. The 2HP configuration uses a different tension rod reference, so K75-19103 should not be substituted.
What does this tension rod do?
It helps maintain linkage tension and alignment between the drive assembly and gate movement hardware.
Should I replace the spring with the rod?
The spring is not automatically assumed to be included. Inspect the parts diagram and replace the spring separately if it is worn, damaged, or listed separately.
What can damage a tension rod?
Gate drag, bent linkage, loose pivot hardware, impact damage, corrosion, or incorrect adjustment can bend or wear the rod.
