Product Description
This is the left hand side gearcase to convert a Tamiya TRF211XM or TRF201XM/XMW, or TRF201XR to a 3 gear layback (or short laydown) transmission. Unlike the previously released 3 gear laydown transmission, this drivetrain uses the stock Tamiya 27t idler gear to pull the motor rearwards (9mm back from the laydown, 17mm forward from the Tamiya 4 gear motor position) and improves traction in medium/mixed grip conditions by weighting the rear wheels more. It still uses the Yokomo motor plate and the Fibre Lyte shock tower from the 3 gear laydown. The battery plate is unique to this transmission, and it also available from Fibre Lyte. Ask for the Layback Battery Plate.
For the complete conversion you will need this part, the Right Hand gearcase (https://shpws.me/R7a7), the 3 gear Layback hole guide (https://shpws.me/R7a1) and either the transmission brace if you have the TRF211XM (https://shpws.me/QO4x), or the TRF201 Waterfall if you have a TRF201XR/M/MW (https://shpws.me/R4Wf). If you have previously purchased the 3 gear laydown conversion, you don't need a new Transmission brace or waterfall. These are the same as the laydown.
There is an optional Spur Gear Cover. If you don't want a cover you need the Spacer (https://shpws.me/R78x). There is a small cover which wrap over the top of the spur gear to protect your bodyshell (https://shpws.me/R6JE), or there is a full cover which encircles the spur gear as much as possible (https://shpws.me/R6Jr).
To complete the conversion you will need:
Tamiya 27t TRf201 idler: 54262 (includes reinforced ball diff gear too)
Yokomo YZ2 or Tamiya kit ilder shaft: Yokomo part Z2-303I or Tamiya kit
Yokomo YZ2 CAL2 motor plate: Z2-304C
CTE RC 3GL suspension tower (available from Fibre Lyte: email sales@fibre-lyte.co.uk)
CTE RC Layback Battery plate (available from Fibre Lyte: email sales@fibre-lyte.co.uk)
This conversion can be set up with front or rear mounted shocks depending on setup. Tamiya 51449 DN01 R Parts or the 54142 DB01R High Traction Reinforced Arms are needed for front mounting. The 51313 arms from the TRF211 kit only work with the rear mounting.
You will also need assorted bearings and fasteners.
Diff/outdrive bearings - 2 x 1510
Idler - 2 x 1050
Slipper Shaft - 1 x 840, 1 x 1050
It uses the stock rear suspension and clears the 3.0, XA and XB aluminium inboard rear suspension blocks (but not the plastic one from the original TRF201 kit). You do not need the special tapered front block from the XM conversions for this gearcase.
For fasteners you need need:
2 x Countersink head M3 x 10 (front gearcase to tub)
2 x Countersink head M3 x 7 (middle gearcase to tub)
2 x Countersink head M3 x 20 (rear gearcase to tub)
2 x Countersink head M3 x 15 (new front battery stop holes drilled using drill guide)
1 x Countersink head M3 x 10 (rearmost motor plate)
2 x Countersink head M3 x 35 (the other 2 motor plate/gearcase halves)
1 x cap head M3 x 15 (rearmost gearcase)
1 x cap head M3 x 20 + 1 x M3 Nut (middle gearcase and front top gearcase/transmission brace)
1 x cap head M3 x 25 + M3 nut (front transmission brace to battery stop)
4 x cap head M3 x 10 (shock tower mounting)
The bearing seats should all be cleaned out with a scalpel/Xacto knife. The 2.5mm holes should be tapped with an M3 tap. After using the drill guide to drill the front holes with a 3.1mm drill, on the TRF211 plastic tub open out the countersinks using an Xactoknife. Do not use a drill. For the aluminium XM/XR plate, drill the holes and open out the countersinks with a proper M3 countersink drill bit.
Cobra Racing (https://www.facebook.com/groups/539051429511100/) make a bespoke chassis to install either of our CTE RC 3 gear transmissions (Layback here for medium/dirt/all round , or Laydown for high grip astro/carpet). If you need the front standup parts BB26 and BB27 to move to a plate chassis, order these with your transmission (https://shpws.me/RgSC)
