Smashed engine, need help with parts.. (CR125 2005)

Recommended Posts

Hi!

 

My riding buddy smashed the right side of his engine last week. He's on a budget, so were trying to find the parts he need used on Ebay.

The bike landed on a rock, and the engine took the entire hit..

 

We are wondering what parts interchange over which years, eg. will a 2004 clutch basket fit a 2005 bike etc.

Hopefully, the shaft that is fitted to the clutch isnt bent, we havnt checked that yet.

 

Its a 2005 Honda CR125.

 

Parts that are broken:

 

*Engine case clutch cover

*Clutch cover

*Rear brake pedal

*Clutch basket

*Clutch inner hub

*Clutch plates

*Clutch pressure plate

 

So, which year parts fit the 2005 bike?

 

Really appreciate all helpful answers, thanks in advance.

Oh man that is really rough. This exact thing happened to me on my CRF. Came over this blind hill way too fast and was greeted on the other side with a pile of boulders. Clutch side completely smashed just as you described and destroyed every component of the clutch and both the inner and outer covers. It cost me $600 in new OEM parts to fix the damn thing.

Sorry can't tell you which year parts would work on your bike. Figured I would share my misery with you so you know your not the only one who had to deal with that :-)

In case you dont find used parts....
Pro-x makes about the most affordable inner hub in existence.

Tusk sells clutch plate kits for less than anyone else and they actually work great and last as long as oem

Really bad news, turns out the engine case has a crack (the one clutch case cover is bolted to).

 

We were thinking:

 

Drill a small hole where the crack ends so we dont have a fracture guide (for fatigue caused by vibration).

Then get the hole and crack filled.

 

Or 

 

Get it welded, IF the material is suited for welding.

 

What do you think? I will upload pictures later ;)

Ok guys, here are the pics:

Notice how the entire hub is torqued apart from the back pressureplate

That looks pretty bad. I'd be going on Ebay pricing out a used set of cases and covers. I've tried to weld on cases before and it can be done, but the clean up can be more hassle than its worth. Too bad it's not a 98, I have everything you'd need to rebuild it.

You might be able to get  a complete engine or bike cheaper than trying to collect all those parts. It's really jacked. Good luck.

Update:

 

All parts have arrived after ordering from Ebay.

Bike was assembled today, and the engine case is being glued (industrial glue, stands 30MPa (N/mm^2)).

 

Question; Is the coloring inside the waterpump normal, and what causes it? (see picture 2)

Its not my bike, and were using industrial glue that holds 30MPa. Welding is difficult due to the aluminium twisting from the heat, we figured drilling a hole at the end of the crack and using the right glue is the way to go.

 

Any input on the coloring?

For an economic fix, I'd drill a tiny hole (like you suggested) at the end of the crack and then wire wheel the crack so the glue/epoxy or JB weld can stick to the surface.

Glue on engine cases shaking my head at you. Keep an eye out on eBay for a cheap bottom end. You'll need it at some point.
