E: Engine Thrust Washers

[Martyn Goodwin]

Can anyone provide the dimensions of these thrust washers used in the timing case? I am after the ID, OD and (nominal) thickness of each

E95, ET98, E98/1, ET173, ET173/1

Thanks for your help

.505" x.741" x.025"; .381" x.618 x.025"; .318" x.618" x.025"; .314" to.320"x 1.00" x.069" ( a known original with a 30 degree chamfer on one edge),and .628" x.875" x.027" There appears to be serious variation only in ET173.

Correction, Chamfer on ET173 is 45 degrees for 1/16" wide. Two other ET173's measure .056" and .071" thick.

There is also a chamfer on the ID of ET173 - I think its there to ensure a flush fit against the shoulder on the spindle.

No inner chamfer on any of the four I inspected, but did note differing i.d.'s probably to achieve the same result.

Pics of an ET173 I have on hand. Shows the chamfers on each side.
