Well I'm back at working on my Bolens 1000. The head gasket was shot and it had oil leaks to fix. So as long it was apart I'm checking things over, it did run great before other than the bad head gasket.

 

Looking at the crank and rod and its scratched up, not bad but I might get it machined. Now for the rod which is where I've got a question. According to the parts manual the rod isn't inter changeable between the 2, which I assume is because of the stroke being different.

But when I do a search for a TR-10D rod most places list that they're the same and the part numbers don't match up with the manual.

 

Instead of finding a rod I have a TRA-10D that I could tear apart to swap the rod and crank. But if I do that would I have to use the cam out of the TRA-10D because of the compression release?

Only things not interchangeable between the two are the Rods. The TRA has a slightly longer stroke

 

Wont matter which cam you use.

There is 2 different part numbers for the crank in the manual though.

I was unaware of the cranks being different but could be wrong...... Its always a good idea to keep the Rod & Crank together if your still going to use the old rod though as they all wear differently.

 

Light scratches in the Rod can be easily dressed down. As long as your rod is still within specs you should get many more years of service out of it.

I just trying to get it back together keeping a low budget. I'll have to do some more measuring to see if I'd have to actually replace the rod.

The length of the stroke is determined by the crank, not the rod. If the block is the same and the stroke is longer, I'd think the rod would have to be shorter.

You are correct Doug.
