Question: 1981 185s Timing Chain

[madmax]

Looks like one of my 185s's jumped time, it wouldnt start so I took the CDI cover off and turned the engine over with the pull starter, the CDI rotor moved then stopped, then moved again. Also I hear a clicking sound.

Can the chain be replaced w/o removing the cylinder? Any other potentially damaged areas I should look at? It looks to be all original, should I go ahead and put rings in it? Wheres a good place to get gaskets? Would I need just a top end set?

Lots of questions, thanks

It sounds like your chain has come loose. Or your chain adjuster has quite working. You can replace the chain without removing any of the top end of the engine. You just have to pull the side cover off and remove your clutch to get the chain on the bottom gear.

Fuzzy,

Any suggestions on a good place to get parts?

Are engine parts for 185s still avail from Honda?

Thanks

some are still available at your honda dealer. A lot of stuff you can get from www.denniskirk.com they sell one for $21.99. #11-9272-100

The chain runs $42.75 from www.partfish.com

Thanks Fuzzy. Dennis Kirk looks like a good source.

I tried www.partfish.com and it appears that there is no info there on 3wheeler stuff (unless I didnt look in the right place)

I took the 185s apart and found that the long angled cam chain tensioner has broken. So should I replace the guide on the opposite side of the chain also? I'm not sure how to get it out of the engine. Also, what do I look for as far as wear on the cam/crank gears?

Thanks
Max

Can you tell if the other one is worn out also. It is not uncommon to wear on one side. But it wouldnt be a bad idea to change both. As far as the gears go you want to check the teeth on the gears to make sure they arnt all rounded off and the chain would slip over them. Kind of like your sprockets for your drive chain.
