Blake, did you get a lot of snow yesterday?

I hope you had your Cletrac ready!

Good Luck!
Ray

140 ft lbs. If you are working on your OC4 you should invest in a shop manual, it will save time and frustration;)

I'm not sure of the exact year, 1930's. The orange was a repaint. I have new reproduction lower side panels for K20 and W12.
Ray

Hello, looks like a project! We have some W parts, you can email (text only) for availability.

Ray

Thanks Blake, good to see you back! I hope the hackers get their cletracs running before they get mad again!

Ray

That sounds like an OC4 Aftatrack, The under carriage was built by a company in Sweden, and was used on several different brands and models. This was advertised alot for logging applications. The main Oc4 crawler was the same except for the undercarriage.
Parts are scarce for the undercarriage, unless there are some available in Sweden, maybe erik knows.
I could fax some info if you want, sorry I can't scan anything at this time.
Ray

you bet, Mike,
just roll them out the back, no problem.
Ray

That should be a 20 amp fuse.

Yes, the HG's all had that glass bowl, then a copper line running to the carb.

I do have those rubber grips new again

Most likely the differential was put in with the gear on the wrong side. (flipped)

Or your crawler has an auxillary trans with it shifted in reverse.

Ray

WOW!

Check to see if the drive shaft between the trans and the clutch is turning. If not check the reverser trans right behind the cutch.

OC46 usually has a spotturn (clutch disc)type steering system and can be costly to rebuild ($500-$1100)

Maybe someone else has some more ideas.

Good luck
Ray

firing order is 1-2-4-3

Good Compression is 100-110 psi

A worn engine will run ok if all the cylinders have equal compession, say 70-70-70-70

good luck

Welcome,
Use O-I-L and absolutely no grease! If they had grease in them, there is no need to take them apart to clean them out, just pump oil into them and it will dilute the grease. If you need an adapter for your zerks give us a call.
Good luck
Ray
