Rebuilding The LT5 Tensioner

I attempted this tensioner rebuild and cracked my back casing on the factory LT5 Tensioner while trying to tap the fresh tension spring in. I've called all around and nobody has a used/core available for sale.

I just installed a slew of new parts including injectors, radiator, ignition coils, starter, cam sensor, and knock sensor to get my ZR-1 Back up and running and now I'm dead in the water since I can't get a replacement tensioner.

Can anyone give me some guidance on how to compress the spring to fit in into the housing? I'm trying to practice installing the spring back in the L98 Donor Part casing, and I've used a vice, and a set of 20" Pliers to try and compress it and no matter what I do I can't get it compressed enough to fit back into the casing...

I just finished rebuilding my tensioner with these instructions and a L98 tensioner purchased from Amazon - fairly straightforward task.

ManPro - I ended up putting the spring in a vice with half of the width of the spring exposed. This allowed me to compress it enough to get the cover started. Once you get it started you can remove it from the vice and use a pair of channel grips to fully seat the spring.

Does anyone have the current part # for the L98 tensioner? Everyone seems to be out of stock of the Dayco 89298 which makes me think it may have been discontinued. Or, does anyone know of another tensioner that has the same "guts"?

Ecklers claim this to be correct for LT5. Can anyone confirm this??

Link I posted is pulleys for L98.

The link posted to Eckler's website claims to fit both.... base and ZR-1.

Winter projects on the Z, will include a tensioner rebuild for my 91 @ 64,000 kms and upon reviewing this thread all the knowledge one requires has been shared by those who went before as expected, thanks guys for making it possible for the rest of us. Has anyone actually verified the Eklers claim of fitting the LT5 or is it still a donor part we are dealing with?
