Engine case questions

In the process of an overhaul I broke a couple of bolts and screwed up a couple holes on the cases. Found a full cases on flea bay from an 82 spectre. Will the spectre cases line up with all of my original LTD internals?? Help please ends soon

factory part number for spectre was 14001-5118 and for LTD was 14001-5091

A different part number does not necessarily mean the part will not work. Any change by Kawasaki will result in a new part number - even a cosmetic change. Since the Spectre is a gold/black bike as opposed to the Ltd being chrome, the discrepancy in the engine cases could be as simple as the color.

that was what I was thinking but just wanted to make sure before dropping coin on a new case

spectre is shaft drive, ltd chain there may be some compatability problems with certain components

I'm not saying it'll work.

Just pointing out that a part number difference doesn't necessarily mean a part can't be used.

Kawasaki.com shows KZ750 cruiser models including chain-drive LTD plus shaft-drive LTD plus shaft-drive Spectre plus belt-drive LTD. Accordingly, cricketfire46's bike could be either shaft or chain or belt driven.

Imo the safest bet for match-up would be Spectre and LTD-shaft.

Am wondering if the existing cases are beyond hope of feasible repair.

Good Luck!

I bought a bike a while back with the two bottom holes that hold on the clutch cover compleatly stripped out. I split the cases, put them up on my bridgepot mill and drilled them out and put inserts in them. Worked out great.
I can do yours too if you are interested. I do machine work for a living. Let me know if I can help you out.

The Spectre cases should work fine. The differences are from the output shaft out. Otherwise it is a standard J case. The Spectre case a Goldish Titanium color while the LTD is silver. That should be the only diference, and the serial #.

My LTD was a chain drive, and the spectre was a shaft, we know this. After looking on the kawasaki factory website, all the output bearings matchup. I will be using all of my internal parts so my mechanic thinks I will not have a problem. If anyone knows different please let me know. From what the site said and the mechanic said these should matchup other than colors. Again any info would be appreciated, but for the price I just cant pass this up to have a case that I dont have to spend an arm and a leg to get machined out.

thank you otakar You are a guru and made my mechanic very confident when he just read that.
