Another thing I'll add; often times a parts listing will show it fits a L245 (for some reason I think they where a lot more common than the 285/295/305/345/355) but if you check, sometimes the part number is identical and fits. Looks like engine rebuild kits are available for about $550 on ebay/Amazon, ect; but I think I would pull the glow plugs, and put some diesel/atf in cylinders and gently rock it.
Don't know about the 295, but the 285 and 245s Had to use glow plugs, and a strong battery, or they wouldn't start, even on a 90 degree day. Once(if) you can free it up, check glow plug function,
