Hey guys, I just got done install a trans in a 2001 windstar what a bi*** rust,rust,rust and bolts breaking everytime.But the question I have is about a 93 mitsubishi galant 2.0 sohc, I was installing a oilpump housing and notice how much looseness in the the balanceshafts and removed them to inspect, finding the front bearings ok the rear bearings were completely gone and the rear parts of the shafts has been ate up,I have manuals showing the shafts but not installation of bearings,and I just bought 2 new shafts/bearings cost around $500 in parts not counting oilpump assembly. I was hoping if someone would know about the installation procedure or were I could find the info.

Dave..
This is all I got..hope it helps..let me know......
This is for the SOHC 16 valve engine...
Fig. 52 Silent Shaft, Oil Pump & Front Case Assembly 
Refer to Fig. 52 , when removing silent shaft, oil pump and front case. Keep silent shaft in position by inserting a screwdriver through plug hole in left side of cylinder block and remove oil pump driven gear securing bolt.
- Inspect oil holes for clogging and clean if necessary.
- Inspect left silent shaft front bearing section for wear, damage and seizure and replace as necessary.
- Inspect front case for cracks or other damage and replace as necessary.
- Inspect oil seal lip for wear, damage or deterioration and replace as necessary.
- Inspect journal for seizure, damage or contact with bearing, replace as necessary.
- Inspect silent shaft oil clearance. Clearance should be as follows:
- Front- Right (0.0012-0.0024 inch).
- Front- Left (0.0008-0.0020 inch).
- Rear- Right and left (0.0020-0.0036 inch).
- If clearance is out of specification, replace silent shaft bearing, silent shaft or front case assembly as necessary.
- Position oil pump gear to front case and rotate to ensure smooth rotation with no looseness. Ensure there is no ridge wear on contact surface between front case and gear surface of oil pump cover.
- Measure side clearance. Clearance should be 0.0031-0.0055 inch (drive gear) and 0.0024-0.0047 inch (driven gear).
- Ensure oil cooler bypass valve moves smoothly on engines with air cooling type oil cooler.
- Reverse procedure to install, noting the following:
- Using oil seal installer tool No. MD998375-01, or equivalent, install crankshaft front oil seal into front case.
- Apply engine oil amply to gears and align mating marks, then install oil pump drive and driven gear.
- Coat threads of oil pressure gauge unit and oil pressure switch with 3M ATD sealant, No. 8660, or equivalent, and install in that order avoiding overtightening.
- Apply engine oil to outer surface of right silent shaft rear bearing, then install ensuring oil hole of bearing is aligned with oil hole of cylinder block.
- Apply engine oil to left silent shaft rear bearing outer surface and bearing hole in cylinder block and install. Left bearing has no oil holes.
- Using bearing installer tools, No. MD9987373-01 and No. MB990938-01, or equivalent, install silent shaft front bearing .
- Install front case assembly through a new front case gasket, then temporarily tighten flange bolts.
- Insert a Phillips screwdriver into a hole in the left side of cylinder block to lock silent shaft. Tighten flange bolt to specification.
- Install new O-ring to groove of front case, then the plug and tighten to specifications.

Damm Jim, thats it, parts#29 to #33 wondering if engine has to e removed?,already done ring job on it 2 years ago,if only applies going thru front case no problem, the removal of the rear bearings might be tricky,have to check my bearing installation tools,Jim thanks a million, it seems like I get the sh*** jobs and they have someone else for the easy ones .This is why mechanics drink and I might be seeing J/D tonight. thanks again Jim.

"Kewl"
Glad that helps...
Know what your saying about the S*** jobs..used to get 'em all the time..
But in the shop,I use to look at it as ...I was the one they trusted to do this job..not every one can do this correctly..
at least tell yourself that until its over.....makes it go easier...LOL....
Better get over and get some "Makers Mark...seems to do wonders for some..or so I've heard....
I heard ( insert name here) went to donate blood and all that came out was Bourbon...Kentucky's finest ,I might add..
  
Good luck
