Jetronic pulse generator

Adjustment, testing and repair for Bosch Jetronic pulse generator in the ignition distributor.

Masterful: Original Made in Germany

The overhauled ignition distributor is tested on our ignition distributor test bench. Adjustments are made to the weights and/or springs of the centrifugal adjustment until it operates within the factory specifications. The ignition contacts are machined to ensure the correct closing angle in all load and speed ranges. The test results are recorded on an original test report and enclosed with the unit. The reconditioned distributor is supplied ready for installation and can be used immediately

Basically, the running-in is carried out on the test bench. However, if, for example, a new pinion is installed, it must be run in again with the camshaft and the appropriate lubricating paste must be used during installation. If you have any questions, please contact our master mechanic team.

We always use original parts, where possible also NOS (new old stock). Where spare parts are no longer available, we produce small batches of spare parts for your distributor ourselves that meet or exceed the manufacturer's specifications. All our distributors meet the manufacturer's specifications (e.g. map) on acceptance.
