we brought in a 1630 into our shop.. has a loader and a broken block now.. loader mounts to a group of 4 holes on either side of the front of the block.. the holes have a small raised area where the bolts go it.. maybee 1/4" raised area. loader was dealer installed
here's the deal.. looks like this happened because the dealer used TOO SHORT of bolts.. in fact.. there are 4 bolts oneach side.. looks like the dealer used 3 short bolts and 1 long bolt. the long bolt was used in the forward lower hole, and the 3 shorter bolts were used inthe back lower, and both upper holes.
This is what happened.. the 3 short bolts were just barely into the block.. the 3 bolts on each side broke out a 'ring' oc block material... that raised lip I told you about.. that came off with each bolt.. plus maybee another single thread onthe block.. IE.. the bolt was only in about 2-3 threads.. the holes were plenty deep.. looks like another 1.5" - 2" of bolt could have gone in there.. just like the lower forward holes where a long bolt was used... here, the bolt broke out the bottom of the block in a pie wedge shape at each of the 2 bolts, with the top of the bolt hole as the center point of the pie wedge.
The other 3 holes on each side did not breach the block, and that lower forward hole that was damaged is not into a water or an oil area of the block, we are going to clean it up, and braze that wedge back in on each side and then polish it so the oil pan will mate up.. and the laoder is going on another identical tractor that has no loader.
Nothing else uses these holes.. so we figure it should be fine. no water has shown up in the oil.. or oil in the water since the damage occured.. though oil does dribble out the cracked areas when running.
Anyone see a problem with brazing her up and making a new oil pan surface and buttoning her back up?
good job dealership mechanics! you saved 1 $ buy buying 6 short bolts instead of 6 longer botls.. and cost a loader tractor!
