IMS Tool Problem

[cnavarro]

Early driver tools allowed for the bearing to be secured to the driver.

We had a shop have 6 ims retrofits fail. Turns out the same tech did each one and was using an air tool to drive the nut down on the install tool, which damaged the bearing even prior to installation, pre-disposing it to an early failure.

I figured that if one person was stupid enough to do this, there have to be others and promptly redesigned the driver tool to prevent the user from securing the bearing with a nut. Problem solved :-)

If our procedures seem to be borderline paranoid or ocd, there is a reason behind everything we do and require.

So did the shop purchase 6 new engines for the unfortunate owners?

Charles - your 17 pages of Instructions are word perfect. I wish all vendors used such Instructions.
When IMSB questions come up I often mention your 17 pages to the guys who say : "slap it in, get 'er done 'n have another beer' .
Most of us are doing an IMSB Retrofit for the first time. It is a daunting task because going back in to remedy a faulty install is awful. That assumes you get that 'opportunity'!
So thank you for taking the time to write it up. It must have been frustrating to try to imagine every conceivable way an Installer could screw up a repair job that is "just procedural" to quote our mutual friend.

In my post further above, I linked a couple versions of the instructions directly from LN Engineering's IMS retrofit web page. The link to download the Single Row Pro and Dual Row IMS Retrofit has a single page of instructions as does the "Single Row Classic IMS Retrofit only". The IMS Solution manual is 31 pages, about 25 of which are installation instructions. I have often read your "17 pages of instructions" statement. Count me as one of JFP's idiots, because I can not find it. ...and yes, I have searched for 10 minutes for my car keys to find that I am holding them in my hand. Where is the 17 pager?

It is a pdf .
When I tried to open it from my Bookmarks I got a 404 Message.
I am sure LN would have what you need.
