Good morning Doc, and thanks for the compliment although I will forgo
any and all praise and defer to Nelson Riedel for all his efforts and
work.
1. the Gunst bearing with the Sachs clutch and pressure plate. You
feel that this is the best combination?
Yes I do. I was running the Koyo bearing with a LUK pressure plate in
the car prior to this replacement. The KOYO bearing has a large ID
measurement - larger than the RHP bearing. One of the things that I
feel contributes to the problems is the large diameter of the t/o
bearing coupled with a pressure plate with cranked or bent fingers.
However, the LUK unit doesn't have that (which is a positive), and I was
still experiencing major issues. The KOYO is better made than the RHP,
but like Nelson, I whole-heartedly agree that the Gunst is a better made
unit. One thing that really got my attention about the Gunst when I
first learned about it was the fact that the sleeve is made of bronze
and not hardened steel, and the trailing edge of the sleeve is chamfered
so there is less chance of binding on the front cover. Bottom line,
Gunst is better than KOYO.
*** One note *** Dick T. is not using the Sach's pressure plate - he
is using a Borg & Beck unit. This will result in a slightly stiffer
clutch - which is ok, as mine is very soft. However, I would shy away
from any B&B unit that had the cranked fingers - this is my personal
preference. Dick might be able to offer some advice on this subject.
2. Are they similar in size in your thoughts?
No, they are not at all similar in size except the I/D obviously. The
O/D of the Gunst is significantly smaller, which I regard as a positive.
3. Also did you put any type of lubricant on the main shaft around the
Gunst or are you relying on the bronze and steel to work together?
Yes, I lubricated the main shaft, bearing, sleeve and even the face of
the pressure plate with molly grease.
4. Excellent web site and write-up on your install.
My thanks once again to Nelson and Dick for their help; without with I
would still be driving around with a pitiful clutch.

Subject: Gunst and Sach
I noticed your write up on the smooth Gunst bearing. I recently got one
myself and am presently working on my transmission doing a J install.
My question is - the gunst bearing with the Sach clutch and pressure
plate. You feel that this is the best combination. I am questioning
this as the fact that most use this clutch with the Koyo bearing. Are
they similar in size in your thoughts?
Also did you put any type of lubricant on the main shaft around the
Gunst or are you relying on the bronze and steel to work together?
Excellent web site and write-up on your install.
