Cylinder & Crankcase
SUBJECT: Studs replace capscrews to secure electric starter and
generator mounting brackets; 40 H.P. Models RDS & RDSL-22 thru 23.
A change was recently made on 1961 model RDS series production engines
which consists of using studs instead of the former washer-faced
capscrews to secure the electric starter and generator mounting
brackets to the powerhead. Figure 1 illustrates the new parts
involved in this change.
Since the studs are also used to secure generator mounting brackets,
three complete sets of the parts illustrated in figure 1 will be
included as part of future generator kits for the RDS series engines.
These studs are also interchangeable on those 1960 and early 1961
model RDS series engines which have starter and generator mounting
brackets secured with the former capscrew. Because we suggest re-
placing all such capscrews whenever you service any engine which still
uses them, the following installation pointers are given to assist
you in properly installing the studs:
1. The end of the stud with the coarse thread must be entered into
the cylinder block, figure 2.
2. THIS STEP IS IMPORTANT: To insure holding power, apply some
"Lok-Tite" compound to the coarse threads before entering.
3. Install all starter bracket studs so
1 3/8 inches extends from the casting,
(measured from face of boss).
4. Install all generator bracket studs so
1 9/32 inches extends from the casting,
(measured from face of boss).
The parts illustrated in figure 1 are
available from your Parts Distributor at
the following list prices which are subject
to the standard parts discount. We suggest
ordering and maintaining an inventory of
these parts in sufficient quantities so they
will be immediately available whenever a
1960 or early 1961 engine is brought in for
service.
