KidandhisCar Posted March 19, 2015 Share Posted March 19, 2015 (edited) ]Hi gents,first time poster long time lurker. Long story short two weeks back I had the engine in my 82 280zx sling a rod, (stock l28E AFAIK). Found a local guy with a L28E pulled to be replaced with a V8, engine is in good running condition. so I bought it. Now here is my problem.. My car is a 5 speed, and the replacement engine came out of an auto, When attempting to mount to the flywheel from my engine onto the replacement engine i noticed that the fly wheel sticks out about 1/4 farther from the rear engine plate,then it did on my engine. I also noticed that the tail end of the crankshafts are different. the one on my original engine has a shoulder that the flywheel sits on. The one on the replacement engine does not. I can still bolt the flywheel to the end of the replacement engine is just sits about 1/4inch farther from the rear engine plate,than it did on my engine. Both are F54 Blocks,and P79 Heads, All stock. Please Advise.

NewZed Posted March 19, 2015 Share Posted March 19, 2015 You need to lurk harder. I've never had one but have read often about the spacer on the end of the crankshaft used for the automatic transmission flex plate. Pretty sure I can see the separation line in your pictures. Pry or pull it off and you should be where you need to be. Quote Link to comment Share on other sites More sharing options...
Pac_Man Posted March 19, 2015 Share Posted March 19, 2015 Definitely the flex plate spacer. Usually it will pop off, but heating and some prying will remove it if it's being stubborn. Quote Link to comment Share on other sites More sharing options...
Project1 Posted March 19, 2015 Share Posted March 19, 2015 You can use a 2x4 butted to the spacer and hit it with a hammer and it will come off. If it's really frozen you can use a puller. You can usually rent them at your local part store for free (w/ deposit) if you didn't have one. Quote Link to comment Share on other sites More sharing options...
Tony D Posted March 19, 2015 Share Posted March 19, 2015 Heating with a crack pipe torch, it falls right off. Or can be plucked early with a needle nose before it's so hot to fall off on it's own. Quote Link to comment Share on other sites More sharing options...
