Old style M25 engine alternator bracket

[Ron Hill]

Someone asked how you can tell if you have the old or the new improved bracket?

The answer is simple and easy to spot - the old bracket that's prone to failure has the adjusting arm over the top of the alternator.
The new bracket assembly has the adjusting arm under the alternator.

The service bulletin put out by Universal Engines applied to all of the M25 engines (1986 C34s) and some of the early M25XP engines (early 1987 C34s).
