Actually now have cab off (wasn't too bad a job).
Trying to refurb an L2 I have. Have got in way to deep. It will be pretty well new when done, if ever that happens.
On most wrecked L2's or L3s I've seen (Gleaner wrecking yard near me) the curved sheet steel at the top of the housing (just behind feederhouse-and can only see when feederhouse is off) has rust holes. Design flaw in that chaff/dust and moisture over 30+ years sits and eats on the trough that the curve creates. Also, there are 2 tabs that are welded on to support the no cab platform on an L (must be the same front end from L to L3s) that trap stuff and that's the worst spot.
Anyway, I'm going to fix this (weld in new curved sheet as well as fix the other sheet right behind the front one (butts up to bottom of grain tank). Now have to take grain tank off and I'll have complete access from above to fix both sheets.
Do I need to do this. No. I'll be the only one that would know I didn't do a complete refurb. For personal satisfaction reasons I'm going to try and do it right.
For anyone interested in what I have done. Putting in new PFP cylinder and new concave plus a rebuilt N5 engine plus 4wd with JD922 flex head with air reel and Headsight AHHC. Balanced both Beaters and all new bearings, sprockets, chains and belts even the straw walker blocks (checked the cranks for true and cracks). New cab interior, isolators, with Grammar air ride seat. Every wear part is new or refurbed (built up a few crank journals on straw walker cranks).
I guess I'm a believer in the L series to go off the deep end like I have. I truly hope this machine performs so I can work off the cost. We will run 2 of them. I'm told it should-we'll see.
