Crankshafts?

[jbsaws]

Well, I've been pretty successful at identifying the parts I have, but the crankshafts have me stumped. The parts lists don't have good images and I'm not sure I can trust the photos I see on line to be correct.

So, I'm turning to you. I will appreciate it if you can give me a positive i.d., with a part number, on the cranks in the photo.

I don't want to offer them for sale unless I'm sure of the part number and application.

They're kind of big for steelhead fishing on the Salmon R., but might be just right for sturgeon on the Snake ;D

Thanks!

Homelite never published bearing and journal specifications so you won't be able to measure your way through this. If you had a lathe or something with centers you could mount it and at least figure out the stroke. That would help narrow the possibilities. The bottom one is typical of the larger saws with a ball bearing at the clutch end held on with a snap ring.

About all the help I can offer is it looks like they all have grooves for opening points, so they're not saws with solid state (i.e. 350-750 or 330/410... etc.). Also, they don't have the extended length on the starter side, so they won't be saws that use the ball/ratchet type mechanism. They'll either be FM or pawls. I you can't dismiss possibility of the overrunning bearing types. The middle one looks like it must be slotted for the clutch instead of threaded, so that can eliminate many saws there. Just about everything after the mid sixties was using threaded clutches, may be a few exceptions, but can't think of any off the top of my head.

Thanks for the replies!

I'll keep working on it and let you know if I come up with anything.

After more reading the service manual, staring at the parts lists and a fair amount of head scratching here's what I'm thinking:

1. I think crank #1 is for xl-12 and crank #3 is for sxl-ao.
2. I'm wondering if crank #2 is for 360.

Even though they are points cranks, they're service replacement parts and maybe they come that way so that they can be used with either ignition.

I'm going to put them in some saws and see if they fit.

As for the theory on #2, 360s were always equipped with the dual piece ignition setup. I've never noticed a crank with lobes for point actuation. Its a bit difficult from the photo to tell for sure, but it does look like its lobed. Question, are there any slots on the clutch side? Can't see form the angle of the pic.

Thanks for the reply. Still learning here, so bear with me.

Lobe: yes, it looks just like the other two cranks on the flywheel side.

Slots on the clutch side: do you mean a slot for a key? It doesn't have any key slots.

I've found a former Homelite dealer with some new cranks. Next time we get by there I'm going to take mine and do some comparing. Won't be for a while, but I'm not in any hurry.

[jbsaws]

I've compared cranks #1 and #3 to known cranks. I've confirmed that #1 is an xl-12 and #3 is an sxl-ao.

Still haven't been able to identify crank #2.

You know what bothers me about crankshaft 2 is there is no LH thread for the clutch to screw onto or is that outside thread LH?
Looking at CS 1 and 2, they do look quite similar in the picture. Is there keyways cut into CS 2 at the boss where CS 1 has threads?

[jbsaws]

You got me thinking the same thing last night. So I compared them. Other than the missing clutch threads, they look the same. So, I think you're suggesting that crank 2 might also be an xl12 without the clutch threads. I think that's a good possibility. I'll take some measurements.

[lesorubcheek]

May be on the right track. There were pumps and circular saws, blowers, and who knows what else the XL-12 engine was used on. May be this crank is for one of these type devices where a clutch wasn't needed.

Thanks for the good replies!

I took cranks 1 & 2 to one of my favorite old Homelite shops this morning. Both cranks measured exactly the same. The owner suggested exactly what Dan said. He's thinking it may be from an XLS pump. Here are two different crankshaft part numbers from the XLS IPL. #58439-1 is the crank for the XLS pump 1 1/2-1. #63497-1 (edit: which I just realized is the part # for an xl-12 crank) is the crank for XLS pumps 1 1/2 1A - 3 - 4.

There is a #58439 for sale on ebay. It has something on the clutch side where the threads would be but the picture is too fuzzy to see if it is threads or maybe some kind of a sleeve.
