SA-3800-12 belongs to a pump-side diesel shutdown family for diesel engines using a Bosch RSV governor. Correct procurement depends on voltage, governor mounting side, lever direction, linkage travel and the complete reference group. Similar cylindrical bodies can use different brackets or switching arrangements, so pump and removed-part evidence must be reviewed together.

Match the complete stamped code because winding, mounting, terminal and linkage details can differ within the same family.
Matching Point | Buyer Review |
Governor or pump | Identify Bosch RSV, RQV-K, P7100 or the installed pump type from the old assembly. |
Mounting side | Compare left/right installation, bracket angle and hole centers. |
Lever travel | Measure the resting position and required run-to-stop movement. |
Voltage | 12V and 24V versions; select by complete OE and old-unit marking |
References | SA-3800-12 / SA-3800-24 / 1751 |
A shutdown complaint can originate in the governor lever, linkage adjustment, pull/hold circuit or wiring rather than the solenoid coil. Watch the solenoid and pump lever during start and stop commands, then measure voltage under load and confirm full mechanical travel.
Observed Situation | Recommended Check |
Rod pulls but engine keeps running | Check pump stop-lever adjustment and lost motion at the linkage. |
Rod pulls then releases | Measure the hold feed and inspect relay or internal switching behavior. |
Movement is slow | Check voltage drop, connector resistance and governor-lever binding. |
Coil overheats | Confirm that full stroke is reached and the pull stage is not left energized. |
Replacement bracket differs | Stop installation and compare mounting side and installed clearance. |
Release the order only after electrical, mechanical and application evidence agrees with the removed assembly. The checklist below keeps fleet, distributor and service-team information on one approval record.
Approval Item | Required Information |
OE and voltage | SA-3800-12 / SA-3800-24 / 1751; 12V and 24V versions; select by complete OE and old-unit marking |
Application | diesel engines using a Bosch RSV governor |
Removed-part photos | Complete label, connector face, both bracket sides and output end |
Measurements | Hole centers, body clearance, resting output length and working travel |
Commercial details | Quantity, destination market, packing and marking requirement |
Keep the complete voltage-specific reference and old-unit marking on the order. The 12V and 24V bodies may share mounting geometry, but their coils are not interchangeable. Confirm machine charging-system voltage at the old connector and label cartons by both OE and voltage to prevent mixed inventory.
Bosch governor applications can use left- or right-hand brackets and different lever directions. A solenoid with the correct voltage may still pull away from the stop lever or sit outside the available clearance. Send an installed pump-side photo and bracket dimensions before the part is released.
Watch whether the rod reaches the run position and remains there after cranking. If it pulls and releases, inspect hold voltage, relay logic, connector resistance and any internal switch. If it stays energized, check whether the governor lever is binding or incorrectly adjusted.
No. The governor family is useful context, while voltage, mounting side, bracket-hole spacing, rod thread and required travel complete the match. Record the full OE group and compare the removed assembly because several shutdown kits serve neighboring Bosch pump families.
Compare the full label, voltage, connector face, terminal count, mounting-hole centers, body orientation, output end, resting length and required travel. Add one wider installed photo showing nearby pump or linkage clearance; close product photos alone may hide the geometry that decides fitment.
Correct the reason the old unit failed before installation. Check supply voltage, pull/hold timing, linkage resistance, mechanical stops, terminal tightness and heat exposure. A new coil can fail quickly when the pull stage remains energized or the plunger cannot complete its designed stroke.
Send SA-3800-12 / SA-3800-24 / 1751, confirmed voltage, diesel engines using a Bosch RSV governor, old-label and connector photos, bracket and output measurements, quantity, destination and packing requirement. Mixed fleets should list each voltage and configuration on separate lines so technical approval and warehouse labeling remain traceable.
Send the complete OE group, confirmed voltage, diesel engines using a Bosch RSV governor, removed-part photos, measurements and order quantity for a fitment-focused B2B quotation.
