It pumps 4 ' idiosome of mounting base to be mounted on cylinder head ontology 3 ' by positioning pin and fastener, processing again makes the two collectively form
Water pump mounting hole 11 ' causes processing technology complicated, cumbersome, and beat is long, and manufacturing cost is high；And the mode of the two Combined machining, lock
Tight bolt is easy to loosen when processing stress is larger, leads to fraction defective height；And after 11 ' completion of processing of water pump mounting hole, also need to tear open
Semicircle water pump mounting base 4 ' is unloaded, is assembled again after cylinder interior is packed into the parts such as camshaft, rocking arm, in order to preferably ensure
Assembly precision, first wife still need to specified pairing in follow-up assembly with cylinder head ontology 3 ' to the water pump mounting base 4 ' of processing and use, lead
It causes production management complicated, cumbersome, is easy error.
(2) manufacturing cost and maintenance cost are higher；
The mode that above-mentioned pairing is processed, used, although the problems such as preferably avoiding mismachining tolerance, rigging error, one
When denier occurs that abnormal quality such as water pump mounting base 4 ' is internal the defects of stomata, sand holes, need by water pump mounting base 4 ' together with
To cylinder head ontology 3 ' scrap together, cause larger cost to waste risk；And when market is repaired, if water pump mounting base 4 '
Damage, has that cylinder head ontology 3 ' is replaced together, larger loss is caused to user.
