Help with 73 250wr transmission

Hi guys, new to vintage Husky's but raced a 450cr in the day..I've acquired a 73wr motor that appears to be rebuilt. My problem is that it is locked in high gear, whatever that is. I researched and see that it is supposedly a six speed. Is that correct? I'm attempting to split the case, have left clutch case off, cylinder and piston removed and also femsa flywheel. My question is which side can be left intact? Should the right side be lifted up with transmission intact to left side and can the clutch be left intact..Sorry for so many questions but all I have for reference is the exploded diagram from our tech pages..Pat

When splitting the center cases on a 73 remove the right side (ignition side), this will leave the clutch side intact. A case splitter is a good idea to insure there's no damage. Many guys make one or you can buy one for about $150.

The 73 250WR did come with a 6 speed. Just to make sure of the year and whether its a true 73WR, or possibly a 73CR (which had the 5 spd) check the engine numbers.

Thankyou Crash! Splitter coming, ser no. Says 73wr, so I'm gonna go with six speed. Yes, gonna pull right side and hope to get it in 4th gear to reassemble. Someone in here before so probably didn't know difference. Thanks again for reply, I guess there's not a lot of old case splitters on here! Pat

Excellent, you ordered a case splitter. It'll save a lot of grief. Some splitters are also assembly tools, they pull the crank onto the main bearing when assembling the cases. Hope all goes well with the repair.

Well, got the splitter, Rocky Mountain Atv, worked like a champ! Less than 5 minutes after attaching, and up it popped? I did this with clutched and left case intact, pulled off right side and proceeded to reset transmission into 4th gear before reassembling the case. Had a CD that had service manuel, that showed assembly of six speed trans. Went back together in one afternoon. So far so good! Keep you posted. Pat

Here's a picture of transmission.
