Installation guidelines for 19mm Pro Kit
12mm Socket Wrench
17mm Socket Wrench
22mm Socket Wrench
Oil Drain Pan
Gasket Scraper - we recommend a carpet razor blade
Additional Tools Suggested:
8mm x 1.25 Tap
4" angle grinder
600 grit sand paper
15" flat sanding bar
Grease & Oil removing solvent aka - brake cleaner
2.5 quarts Penzoil Syncromesh Gear Lube (approximate)
Unscrew the pan plug and drain your current lube into an Oil Drain Pan.
Remove the 12 M8 bolts and pull off the current pan.
As you can see this one had a lot of Silicon sealer.
The 17mm bolt in the upper left is the lube fill hole.
We always wondered why this transmission had a perpetual slow leak.
When the old cover was removed, there were several small dents in
the aluminum case with material displaced up on the gasket surface.
These needed to be removed to get a flat sealing surface. A bastard
file was gently used to remove these "burrs".
On this transmission the machined gasket surface was slightly depressed
to the casting surface. This casting surface was cleaned up with a 4"
angle grinder to make clearance for the new Tuff Pan.
A better view of the "relieved" surface.
Also seen here is the cleaned gasket surface and clean threaded holes.
Brake cleaner was used on the gasket surface and the M8 holes were hand
chased with an M8 x 1.25 tap. There was a lot of gasket sealer stuck
in the threads which needs to come out. Take this time to hand drive
a M8 stud 12mm end to full depth in each transmission hole. The gasket
surface was lightly touched with 600 grit sand paper wrapped around a flat bar.
Everything was again cleaned spotless with brake cleaner and a shop towel. Test
the Tuff Pan against the Transmission surface to make sure it seats completely flat.
The 40mm studs in the 19mm Pro Kit have Pro Seal applied to the
first 3 threads of the 12mm threaded end. This end gets installed
into the transmission case.
M8 Stud installed to full depth.
All 12 M8 Studs fully installed. Once again test fit the Tuff Pan.
Apply a liberal amount of Loctite 518 in a pattern like shown. Its quite thick.
Place the Tuff Pan over the studs and hand press fully against the Transmission.
Install the washers and flange nuts. Torque to 8Nm. Clean up your pan plug and install
with a new fiber washer. Refill the transmission to the proper level with Syncromesh.
