| Twin Cam Recall
On Friday January 8, 1999, a safety recall notice # 095 was faxed to
all dealers and distributors regarding cam bolt breakage on the twin cam engine. Certain
twin cam engines from the start of 1999 production to those manufactured up to September
27, 1998 are affected. Affected 1999 twin cam 88 engines must have a 99 stamped in position
3 and 4 and have numbers from 035 through 270 stamped in position 5 through 7. The
crankcase numbers are stamped on the left side of the engine. A service bulletin containing complete details concerning this
recall will follow to the dealers within 14 days. All registered owners of affected vehicles will be notified by
Harley Davidson to bring the vehicle in for recall service
Andrews is now producing camshafts for the Twin Cam 88 engine. |
TWIN CAM 88 Performance Notice: It is critical that the rear camshaft drive sprocket retainer bolt be
GRADE 8. The bolt must be torqued to 25 ft. lbs. and installed with LOCTITE.
Until steel sprockets are available from Harley-Davidson
(December 1998), there is a danger of the stock retainer bolt heads breaking during normal
engine operations. If the bolt breaks, there will be damage to the engine caused by valve
to piston contact.
This situation can occur in stock bikes produced prior to
October, 1998. Even without changing the camshaft, there is a risk of the bolt breaking.
It is our understanding that bikes produced after October 1998 should not experience the
problem. |
