(3) Place the short end of the oil seal remover and installer J 6270-3 in the oil seal and under the ram of the press.

Then, press the oil seal into the end plate until the shoulder on the installer contacts the end plate.

NOTE

A step under the shoulder of the installer will position the oil seal approximately .005 inch

below the finished face of the end plate. This is within the .002 inch to .008 inch specified.

(4) Install the remaining oil seals in the end plates in the same manner.

(5) Install the blower front end plate, (15), making sure the mark TOP on the outer ribbed side is at the top of the

blower housing, identified by the flange with supports the housing on the top edge of the cylinder block.

NOTE

The front and rear end plates of the blower are interchangeable.

(6) One end plate should be assembled to the front end of the blower housing first and the other plate should be

assembled to the rear of the blower housing after the rotors are in place. Attach an end plate to the front of the blower

housing as follows:

(a) Check the dowel pins. The dowel pin must project .380 inch from the flat inner face and .270 inch from the

outer face of the front end plate to assure proper alinement of the end plate to the housing and the cover to the end plate.

(b) Place the blower housing on a bench with the top of the housing up, and the front end of the housing facing

the outside of the bench.

housing and the end marked TOP facing the flanged side of the housing. Then, start the dowel pins straight into the dowel

pin holes in the housing. Push or tap the end plate against the housing. Note that gaskets are not used between the end

plates and the housing; therefore, the mating surfaces must be flat and smooth.

(d) Insert the two fillister head screws through the end plate and thread them into the housing. Tighten the

screws securely. Do not use lockwashers on these screws.

(7) Assemble the blower rotors in the blower housing and front end plate as follows. The rotor must be assembled

in the blower housing with the omitted serrations in the rotor shafts alined as shown in figure 3-32.
