SERVICE BULLETIN Important – Avoid Cam Shaft Failures
Date August 2002 Service Bulletin #235
Models: Universal M25XPB, M25XPBC, M35B and M35BC
Subject: CAM SHAFT DRIVE TANG REINFORCING SLEEVE
Random reports have been received from the field relative to the failure of the sea water pump drive tang on the camshafts of early Model “B” series UNIVERSALS listed above.
These failures are related to early production models and it has been found that the sea water pump drive tang reinforcing sleeve had not been installed.
Production models with a manufacturing date code of E001 (January 2000) and older are suspect.
Owners/operators are advised to immediately remove the sea water pump off the front gear case of they engine and inspect the cam shaft sea water pump drive end to make sure it has this reinforcing sleeve.
Other illustrations on the Westerbeke web site show the cam end with and without the reinforcing sleeve. http://www.westerbeke.com/Products/ServiceBulletins.aspx
If the reinforcing sleeve is not present contact the Westerbeke Corporation immediately at (508) 823-7677 or email us a help@westerbeke.com referencing this Service Bulletin #235 and a sleeve and sea water pump mounting gasket will be sent at no charge. Please have the serial number or your engine available when making this request.
The reinforcing sleeve is easily installed as it is just a slight force fit fully over the sea water pump drive end of the cam shaft. Position the reinforcing sleeve squarely into the end of the cam shaft and gently tap/push it fully onto the shaft end so it is flush with the end of the shaft.
Reinstall the sea water pump using the replacement mounting gasket supplied with the reinforcing sleeve.
This bulletin, along with a reinforcing sleeve and sea water pump mounting gasket have been sent to all registered UNIVERSAL owners on record owning models listed manufactured prior to January 2000.
A copy of this and all other Service bulletins are available at any Westerbeke/UNIVERSAL dealer.
