4.2 E Type Jaguar - Block machine work |
Update report - May 24, 2009
Your crankshaft has now been ground and balanced together with the rest of the rotating assembly. Per your instructions, we test assembled the crank, set the end lash and trial fitted the front seal. Everything should be ready to ship out to you first thing Tuesday morning.Main bearing clearances, caps torqued to factory specification of 83 lbs ft: #1 .0027", #2 .0023", #3 .0021", #4 .0020", #5 .0020", #6 .0023" and #7 .0024"
Rod bearing clearances, Carrillo rods torqued to .007" stretch: #1 .0018", #2 .0022", #3 .0016", #4 .0016", #5 .0017", #6 .0016"
We have now completed our work with the block. The new sleeves have all been installed and the cylinders honed to size. The Wiseco pistons were (dimensionally) very consistent and each cylinder has been honed for .003" skirt clearance.
I am pleased to report that your custom sleeves have now been delivered and we have already begun boring the block to size and installing the new sleeves. We also received the Wiseco pistons that you had custom made for this project, so we have everything we need to push ahead with the machine work.

With the old sleeves removed, we discovered that we are going to need a set of custom top hat sleeves because the cylinder counter bores have already been cut significantly oversized. Unfortunately, this will add some expense in relation to the custom sleeves and also add a couple of weeks to the project schedule, while we wait for the new sleeves to be made.

Your engine has arrived safely at CJ and we now have your block machine work underway. Initial findings, as follows:There were three helicoils of the wrong type (5/16" -18) that had also been incorrectly installed. One of the dowels by the rear seal was damaged and will have to be replaced. The main housings measured as follows: #1 - 2.9169, #2 - 2.9168, #3 - 2.9171, #4 - 2.9174, #5 - 2.9171, #6 - 2.9172 and #7 - 2.9163. #4 housing was + .001" out of round and #7 housing was .0002" undersize. We have already completed the align hone - see final measurements in second to last photo below.
