POTENTIOMETER FEELER BOARD RJ-13SR Toyota JAT-600 JAT-610 JAT-710 JAT-810 Loom Part HL1025

Product Overview

This is the trimmer potentiometer fitted on the weft feeler board of Toyota JAT-600, JAT-610, JAT-710 and JAT-810 air jet looms. Original part number RJ-13SR, our item code HL1025. It is the variable resistor that sets the feeler detection level on the board, turned during adjustment when the sensitivity has to be brought back into its working window.

The suffix on the marking matters. Our range includes more than one trimmer of this body size, and the version on your board is the one printed on its own body. Two trimmers that look the same from across the bench can differ in shaft, travel or mounting, and a wrong one will either not seat on the board or will not give the adjustment range the setting needs. Read the marking on the old part, or send us a clear photo of it, before ordering.

The reason this small part is worth keeping in stock: when the setting will not hold, the fault is often nothing more than a worn track under the wiper. The board is then replaced as a whole, at many times the cost of the trimmer, and a board that was otherwise sound goes into the scrap bin. A drawer of the correct trimmers turns that into a bench repair.

This item is the potentiometer only, supplied without knob or mounting hardware, and it is fitted at board level, not at the loom.

Frequently Asked Questions

Q1: Is this trimmer the same as the other feeler board potentiometer in your range?
No. This listing is original part number RJ-13SR. Please match the marking on your old part against it, or send a photo, and we will confirm.

Q2: How do I know the trimmer is worn?
The setting moves away from where it was left, the detection level jumps when the control box is tapped, or a meter sweep shows dead spots along the track.

Q3: Can I replace it myself?
It is a board-level part: desolder and solder on the bench, not a loom-side swap. If your workshop repairs boards, this is a straightforward job.

Q4: Is the knob included?
No, the potentiometer is supplied on its own. Please ask if you also need the knob or mounting hardware.

Q5: Can I order samples first?
Yes, sample orders are supported for quality checking before bulk purchase.

Q6: What about the warranty?
Warranty is offered against manufacturing defects, evaluated case by case. Damage from soldering heat or wrong installation is not covered.
