I have a friend who has a Quadra 40. He just got some new rings and is in the process of reassembling the engine.

He is having trouble getting the needle rollers onto the crankpin. Does anyone have a procedure for fitting the rod back onto the crankshaft and then fitting the rollers?.

Do you fit the rollers first and then put the rod onto the shaft?, or do you fit the rollers after the rod is on the shaft?.

I have not seen the engine so I am describing this from a second hand description.


Any Ideas??.

Thanks

use grease to !QUOT!glue!QUOT! the needle bearings in place till the parts are assembled..you can !QUOT!rinse!QUOT! the grease away with a good solvent..or you can leave it in till run..the fuel should clean out any residue when you start the engine..

I just ran accross this post. Hopefully you already have your answer but if you don't, the answer is grease. The grease will make the bearing stick.

Thanks Jeff,

Yes my friend has been able to assemble the engine using grease to hold the rollers in place.


Regards

You can use wax to hold them together.

The new bearing come with a wax.

Best and good luck.

If you don't have wax use vaseline.

I used to use Morroso assembly lube, intended for race car engines.

I have a 41 ? basket case that has had the carb mount welded and only have 8 rollers, couldn't get 6 in place, and think there should be about 10 rollers, anyone know how many there should be? There must be a trick even with wax. Where can I get a parts layout/list? Bob
